ACL Rehabilitation: The Role of Physiotherapy in Returning to Life, Activity, and Sport

ACL Rehabilitation: The Role of Physiotherapy in Returning to Life, Activity, and Sport

by | Apr 22, 2025 | ACL, Gym and Strength, Knee, Return to Sport, Running Injuries

On today’s Praxis what you Preach, we cover a very common injury here in Australia – the Anterior Cruciate ligament (ACL) injury. At Praxis Physiotherapy, we understand that recovering from ACL reconstruction is more than just healing a knee — it’s about restoring confidence, movement, and returning to the activities and lifestyle that matter most to each person. Physiotherapists are uniquely placed to guide this journey from surgery through to return to everyday function, recreation, and sport.

What is an ACL Rupture?

The ACL is one of the key stabilising ligaments of the knee, crucial for controlling rotation and forward movement of the tibia. An ACL rupture typically occurs during sudden changes in direction, pivoting, or awkward landings — common in sports like AFL, soccer, basketball, and netball. It most often affects young, active individuals, particularly females, due to biomechanical and hormonal factors. While not all ACL injuries require surgery, those with complete ruptures who wish to return to cutting or pivoting sports usually undergo ACL reconstruction. Regardless of the surgical decision, structured rehabilitation guided by a physiotherapist is essential for a successful recovery and long-term knee health.

The Importance of Physiotherapy in ACL Rehab

Research shows that while around 80% of individuals return to some form of sport after ACL reconstruction, only 65% return to their preinjury level and just 55% to competitive levels (Andrade et al. 2020). Physiotherapy plays a vital role in improving these outcomes by guiding progressive rehabilitation and using structured criteria-based progressions.

Physiotherapy-led rehabilitation should begin early, with emphasis on knee mobilisation, weight-bearing as tolerated, and initiation of neuromuscular training (Andrade et al. 2020). The BJSM systematic review of clinical guidelines for ACL rehab supports early kinetic chain exercises (both open and closed), strength training, cryotherapy, and neuromuscular stimulation when indicated (Andrade et al. 2020).

From Healing to Performance: A Continuum

Recovery after ACL surgery should follow a continuum from impairment-based care to performance restoration. This includes early pain and swelling control, progressive strength and range of motion restoration, motor control retraining, and sport-specific preparation. At Praxis, we follow a phase-based rehabilitation model tailored to individual needs. These needs may include the type of surgical graft used, concurrent injury (e.g meniscus / MCL), the operating surgeon’s post-op protocols, the patient’s goals, sport-specific demands, timelines for return to competition, and previous levels of function — all of which require thoughtful and collaborative clinical decision-making.

Unfortunately, studies show that many patients are discharged before meeting strength or performance benchmarks — particularly in strength-focused exercises like the split squat, squat, or deadlift, which play a vital role in ACL rehab progression. For example, performing around 22 single-leg sit-to-stands is one such late-stage benchmark that reflects adequate quadriceps strength and control before return to sport (Welling et al 2018). Nichols et al. (2021) found that most published rehabilitation protocols emphasize endurance and hypertrophy without progressing to the strength or power needed to reduce reinjury risk. This underlines the need for physiotherapists to include high-intensity, sports specific strength training and late-stage performance metrics as patients near return to sport.

Addressing Muscle Atrophy and Weakness

Quadriceps atrophy remains a key barrier to recovery post-ACL reconstruction. Evidence supports adjunct interventions such as neuromuscular electrical stimulation and blood flow restriction (BFR) training to combat muscle loss, particularly in the early post-operative period (Charles et al. 2020). BFR combined with low-load resistance exercise has been shown to reduce muscle wasting and promote strength gains when higher loads are contraindicated — we explore this more in our Blood Flow Restriction Training blog. We use this frequently at Praxis Physiotherapy in both reformer pilates and early gym based settings. 

The Role of the Physio: More Than Just Exercise

Our job as physiotherapists goes beyond prescribing exercises. We support patients through the emotional and motivational challenges of recovery, address fear of re-injury, and help them develop the confidence to return to sport or physically demanding jobs. We tailor plans based on functional goals, sport-specific needs, and personal circumstances.

At Praxis, this also means working closely with coaches, GPs, surgeons, and families to ensure clear communication and aligned expectations. For sporting patients, this might include on-field rehab or comprehensive return-to-play assessments in collaboration with clubs and teams.

A Collaborative, High-Performance Rehabilitation Environment

At Praxis Physiotherapy, we bring high-performance rehab principles to all patients — not just elite athletes. Our team has provided physiotherapy services to the Aspley Hornets AFL Club since 2014, giving us deep insight into the physical and mental demands of competitive sport. We apply this same standard of care to everyday athletes, weekend warriors, and anyone seeking to return to an active lifestyle.

We also work closely with orthopaedic knee and shoulder surgeon Dr. Kelly Macgroarty, including in-room triage consulting, ensuring a seamlessly integrated, evidence-informed rehabilitation pathway. This collaboration allows us to align surgical timelines, post-op considerations, and physiotherapy progressions — from day one to return to sport.

Our clinical culture is shaped by exposure to elite-level sports environments, including AFL, representative athletics, and professional national cricket programs. But rather than highlight individual accolades, we’re most proud of the high clinical standards and systems-based approach that ensure our entire team delivers the same quality of care — no matter who walks through the door.

Each of our Brisbane based clinics includes access to gym facilities and reformer Pilates equipment, allowing for real-world, function-driven exercise. These resources support patients to not only recover structurally but also return to high levels of strength, coordination, and performance in line with the latest evidence-based guidelines.

A Message to Our Patients

Whether you’re an athlete aiming for competitive return or someone wanting to run after your kids again, we bring the same level of care and attention to your ACL rehab. Recovery is not just about timelines — it’s about building back strength, movement, and trust in your knee. Ready to get started with your own recovery plan?

Hamstring Strain Injuries: Lessons from Personal Experience and the Latest Research

Hamstring Strain Injuries: Lessons from Personal Experience and the Latest Research

by | May 29, 2023 | Gym and Strength, Return to Sport, Running Injuries

Recently, in an effort to keep the ballooning effects of the all-you-can-eat buffet at bay during my Cricket Australia Indian tour, I ramped up my high-intensity running load. Things were going splendidly — four days of high-intensity running under my belt — until day five, when 90% of the way through a very intense interval session, I tore my hamstring.

I felt the tell-tale sensation so many of my patients describe: a sharp tearing and retraction sensation in my outer thigh while sprinting. I had to pull up immediately and iced the injury straight away. You’ll be happy to hear that I’ve since fully recovered. No longer ‘gun shy’ at my top speeds (which, admittedly, are not that fast!), my strength has vastly improved, and I’m back running at full capacity.

Having treated countless hamstring injuries through my long involvement in recreational, semi-elite, and elite sport — especially with Cricket Australia teams and the Aspley Hornets NEAFL squad — this experience gave me even deeper appreciation for how tricky these injuries can be. Hamstring strains are one of the most common injuries in running athletes, responsible for significant downtime and lost performance. Hamstring injuries have remained the most prevalent injury in professional AFL for the past 21 consecutive seasons (Orchard et al., 2013), with the average 2012 injury costing clubs over $40,000 per player!

Understanding Hamstring Injury Mechanisms

Most hamstring tears occur during the late-swing phase of running, where the hamstring undergoes rapid lengthening while producing high forces (Danielsson et al., 2020). Key risk factors include:

  • High eccentric loading demands.

  • Poor neuromuscular control.

  • Muscle imbalances (particularly hamstrings vs quadriceps).

  • Fatigue — as evidenced by my own injury, occurring late in a demanding session!

Importantly, the long head of biceps femoris is the most commonly injured muscle, partly due to its higher proportion of fast-twitch fibers and its anatomical position under stretch during running (Martin et al., 2022).

Fatigue, poor trunk/pelvic control, and sudden spikes in high-speed running are emerging as significant contributors to hamstring strain risk, particularly in field and court sports (Martin et al., 2022).

Preventing Hamstring Injuries

The good news is, hamstring injuries can often be prevented with smart training. Strengthening the hamstrings through eccentric exercises like Nordic hamstring curls and single-leg Romanian deadlifts has been shown to reduce injury rates significantly (Al Attar et al., 2017; Martin et al., 2022).

Effective prevention programs should also include:

  • Agility and trunk stabilization exercises — not just strength work (Martin et al., 2022).

  • Warm-up routines with dynamic stretching and sport-specific drills.

  • Monitoring high-speed running loads to avoid sudden spikes in intensity.

Addressing muscle imbalances is key too. Maintaining a healthy strength ratio between the quadriceps and hamstrings — and ensuring good trunk and gluteal control — promotes optimal biomechanics and reduces injury risk (Martin et al., 2022).

Recovering Well After a Hamstring Injury

A proper recovery should include:

  • Early management: Controlling swelling and pain with ice and appropriate activity modification.

  • Progressive eccentric strengthening: Integrated carefully to build resilience.

  • Functional rehabilitation: Sprinting drills, agility work, and sport-specific movements are crucial before returning to full play (Martin et al., 2022).

Interestingly, studies show athletes who follow programs that include eccentric training and trunk stability work have lower reinjury rates than those who just focus on basic strength and stretching (de Visser et al., 2012; Martin et al., 2022).

Return-to-play decisions should be made carefully. Factors like strength symmetry, absence of pain, and readiness for high-speed running should all be considered to reduce the risk of reinjury, which can be as high as 30% otherwise (Martin et al., 2022).

Final Thoughts

Even as a physio, my personal hamstring tear was a stark reminder that fatigue, progressive loading, and structured rehab are vital ingredients for both prevention and recovery. Whether you’re a weekend warrior, a professional cricketer, or just trying to beat the buffet, hamstring health is crucial.

If you’d like help strengthening your hamstrings, managing an existing injury, or optimising your running and performance, feel free to reach out. I (and my hamstrings) would be happy to help!

Understanding the “side strain” in cricket fast bowlers: Your guide to rehabilitation

Understanding the “side strain” in cricket fast bowlers: Your guide to rehabilitation

by | May 26, 2023 | Gym and Strength, Return to Sport

Cricket is a game that demands immense physical prowess, especially from fast bowlers who generate incredible power during the delivery stride. However, it is this intensity that can often lead to injuries, with side strains being a common condition among cricketers. In this blog, we will discuss the causes, prevention, and rehabilitation strategies for cricket fast bowler side strains, shedding light on the often vital role of physiotherapy in ensuring a successful recovery and return to play.

What is a side strain?

Side strains, also known as intercostal muscle strains, typically occur due to the rapid rotation and forceful actions involved in fast bowling. The repetitive and high-intensity nature of this movement can lead to fatigue and ultimately a single incident leads to a tear of the intercostal and or oblique (more frequently internal oblique) muscles. It is these muscles that are responsible for aiding in generating stabilisation of the rib cage and force generation during the powerful trunk rotations during bowling actions. A side strain is characterised by the onset of pain and localised tenderness over the lateral trunk near or over the rib cage, usually on the opposite side to the bowling arm. It is often felt after a single delivery when the front arm “pulls” down during the delivery action. Side strains require rehabilitation and often significant time spent away from sport. In fact, side strains are the second longest injury that keeps a player out of cricket other than a lumbar stress fracture.

Risks

The early part of the competitive playing season has been associated with relatively higher incidence of side strain injury, particularly in younger bowlers. Those that are returning from a different injury that has limited their bowling loads are also at risk. Fast bowlers, as opposed to spin bowlers are at a much higher risk given the higher forces associated with fast bowling. Finally, those who have sustained a side strain are also more likely to re-injure that same season.

Diagnosis

Diagnosis of side strain is based on the athlete’s clinical history and physical presentation. An MRI may also be utilised to confirm the diagnosis. Clinical features include acute pain over the outside thoracic wall over one or more of the lowest four ribs. There is also pain on activation of the oblique muscles in activities such as resisted side bending or rotation. Deep inhalation can sometimes be an aggravating factor.

Management

The goal is to allow the injured intercostal muscles to heal fully, regain strength, and gradually reintroduce sports-specific movements before returning to full competitive play. On average, it may take upwards of 4-5 weeks to return to sport. More severe side strains can take longer to heal, typically requiring 6 to 8 weeks or even more. However, early management and loading of the side can improve prognosis and return to play timeframes. It is important to graduate from low level exercise through to more challenging sport specific exercise (shown below). It is also important to cross train wherever you can so that you maintain as much lower body conditioning as possible.

In summary, fast bowling is tough work so your body has to be strong and resilient. Good structured strength training helps! If you do suffer a side strain, patience, adherence to rehabilitation protocols, and close monitoring are essential for a successful recovery from a side strain.

Split Squat vs Squat vs Deadlift: How to tailor your lower body training

Split Squat vs Squat vs Deadlift: How to tailor your lower body training

by | May 26, 2023 | Gym and Strength, Return to Sport, Running Injuries

The age old question: What’s the best gym activity for my sport? Well – the answer should always be “it depends”. Even the same athlete playing the same sport will have different requirements at different parts of a season. Generally speaking, there are some common exercises in utilised by strength coaches when programming for athletes. The split squat, squat, and deadlift are all compound exercises that target various muscle groups and are commonly included in strength training programs. In today’s Praxis What You Preach article, we are going to breakdown the kinematic (joint angles) and inverse dynamic (joint forces from assumed joint angles) differences between these exercises. We’ll also briefly discuss what sports may benefit, but as just mentioned, the answer is “it depends”.

The Split Squat

The split squat is a unilateral lower body exercise that primarily targets the quadriceps, hamstrings, glutes, and hip stabilisers. It is a personal favourite of mine as I believe it replicates many athletic positions and helps identify any asymmetries there may be. In this exercise, you start in a staggered stance with one foot forward and the other foot positioned behind. The front leg performs most of the work, while the back leg provides support.

The Movement

  • The front knee flexes and extends, moving vertically.
  • The rear leg remains relatively stationary, providing balance and stability.
  • The hip joint of the front leg moves through flexion and extension.

What’s working?

  • The front leg experiences greater joint forces and moments due to supporting most of the load.
  • The knee extensors (quadriceps) and hip extensors (glutes) generate the majority of the force to extend the knee and hip joints.
  • The rear leg primarily acts as a stabilizer rather than generating significant force.

Sports?

The split squat is a versatile exercise that can benefit individuals participating in a wide range of sports. Running, jumping and change of direction field sports such as AFL and soccer seem to benefit well due to the asymmetrical load on the pelvis. The increased loading of the hip stabilising muscles make this a useful exercise for tennis players, volleyballers and track and field (eg triple jumpers) athletes as well.

The Squat

An absolute staple of the gym! The squat is a bilateral lower body exercise that primarily targets the quadriceps, hamstrings, glutes, and lower back muscles. For the sake of this argument, talking about a Barbell back squat. It involves descending into a squatting position while maintaining a relatively upright trunk and then returning to a standing position.

The Movement

  • The hips and knees flex simultaneously, moving in a coordinated manner.
  • The knees move forward, tracking over the toes
  • The torso tilts forward slightly, maintaining a neutral spine but a bit of flex here is fine (and biomechanical studies show you can’t not flex the spine)

What’s Working?

  • The quadriceps, hamstrings, and glutes generate force to extend the hips and knees during the ascent phase.
  • The erector spinae and other lower back muscles provide stabilization and contribute to maintaining an upright posture.
  • The knee extensors (quadriceps) experience higher forces and moments during the descent and ascent phases.

Sports?

Squats help with vertical force generation so jumping sports like basketball and volleyball are sports that would benefit. The Barbell back squat is also central in powerlifting, olympic lifting and Crossfit. Given you can load significant weights to the bar, back squats are also useful for football codes whe are required to absorb impacts during tackles.

The Deadlift

The deadlift is a bilateral exercise that primarily targets the posterior chain, including the glutes, hamstrings, erector spinae, and upper back muscles. It involves lifting a loaded barbell or other weight from the floor while maintaining proper form.

The Movement

  • The hips hinge backward, allowing the torso to lean forward while maintaining a neutral spine.
  • The knees flex to a lesser extent compared to the squat.
  • The barbell moves vertically in a straight line close to the body.

What’s Working?

  • The glutes, hamstrings, and erector spinae generate force to extend the hips and maintain a neutral spine.
  • The quadriceps contribute to knee extension.
  • The upper back muscles help stabilize the spine and prevent excessive forward flexion.
  • The lower back muscles experience significant forces and moments due to their role in maintaining spinal alignment.

Sports?

Powerlifting, Olympic lifting and Crossfit are the obvious ones that spring to mind. But tackling sports such as rugby can benefit. Given the predominance of back musculature, rowers will benefit here. Wrestlers and MMA athletes will also benefit due to the whole body nature of a deadlift.

Overall, while all three exercises involve lower body movements, they differ in terms of joint angles, muscle activation patterns, and force distribution. Understanding these differences can help tailor training programs to specific goals and individual needs. We also modify these exercises further to tailor our rehabilitation needs, In that vein, it’s important to be conscious of technique when performing these exercises to maximise their effectiveness and reduce the risk of injury.

So if you are growing stale in your lower body workouts, try and mix it up with some of the above. There are also plenty of variations of the above to alter the movement and forces even more! If you are after some help to modify your gym program, chat to us today – we are here to help!

Split Squat vs Squat vs Deadlift: How to tailor your lower body training

Unilateral vs Bilateral Training: Part 1 – Your Comparative Guide

by | May 19, 2023 | Gym and Strength, Hip, Knee, Lower Back, Return to Sport

We often get asked what are the benefits of one form of exercise versus another. Sometimes this is as simple as discussing the difference between cardio and weights. Today’s article focuses on the difference between a two types of gym based loading programs Bilateral vs Unilateral training. In Part 2, we delve more into some of what the evidence says regarding these modalities.

In general, strength training plays a pivotal role in athletic development, enhancing performance, preventing injuries, and promoting overall fitness. This is especially true for the injured population. As such, our Praxis physiotherapists will discuss with you how your rehabilitation plan will incorporate strength training.

When it comes to strength training though, two primary approaches are often employed: unilateral and bilateral training. Unilateral training focuses on exercises that isolate a single limb or side of the body, whereas bilateral training involves movements that engage both limbs simultaneously. This blog aims to contrast the benefits and drawbacks of unilateral and bilateral strength training methods, examining their impact on athletic performance and overall physical development.

Unilateral Strength Training

Unilateral strength training involves exercises that emphasize working one limb or side of the body independently. One of the significant advantages of unilateral training is its ability to identify and correct muscle imbalances. By targeting each limb separately, athletes can pinpoint weaknesses, imbalances, or asymmetries, and address them with specific exercises. Unilateral training also enhances proprioception and balance by requiring greater neuromuscular control. It activates stabilizer muscles and enhances coordination, which can lead to improved athletic performance and injury prevention.

Moreover, unilateral training allows for greater range of motion and flexibility development, as each limb can move freely without the restrictions imposed by bilateral movements. This can be particularly beneficial for athletes who need to improve mobility and functional strength in specific joints or muscle groups. Additionally, unilateral exercises offer sport-specific advantages by simulating movements that athletes encounter during competition, such as single-leg jumps in basketball, change of direction football or one-arm strokes in swimming.

However, unilateral training does have limitations. It generally requires more time and effort to complete a full-body workout due to the need to perform exercises separately for each limb. Additionally, unilateral exercises tend to involve lower weight loads, which may limit their potential for developing maximum strength.

Bilateral Strength Training

Bilateral strength training, on the other hand, focuses on exercises that engage both limbs simultaneously. One of the primary benefits of bilateral training is the ability to lift heavier weights. This can lead to significant gains in maximal strength and power, making it particularly advantageous for athletes involved in sports that require explosive movements, such as weightlifting or sprinting.

Mid Potion Achilles Tendinopathy Location

Bilateral exercises also promote increased overall muscle mass and hypertrophy due to the higher loading potential. By engaging multiple muscle groups simultaneously, bilateral training can provide a time-efficient method for achieving muscle growth and development. Additionally, the bilateral movements help improve intermuscular coordination, allowing athletes to transfer strength gains more effectively across various activities.

However, bilateral training may not address asymmetries or imbalances as effectively as unilateral training. In some cases, stronger limbs may compensate for weaker ones, perpetuating muscle imbalances and potentially increasing the risk of injury. Moreover, bilateral exercises may not fully translate to specific sport-related movements that often require unilateral actions.

In summary, both unilateral and bilateral strength training methods offer unique benefits and drawbacks for athletes. Unilateral training aids in identifying and correcting muscle imbalances, enhancing proprioception, and improving sport-specific movements. It is a valuable tool for injury prevention and rehabilitation. On the other hand, bilateral training allows athletes to lift heavier weights, develop overall muscle mass, and enhance intermuscular coordination. It is particularly effective for activities that demand explosive power. Ultimately, the choice between unilateral and bilateral training should be determined by an athlete’s specific needs, goals, and the demands of their respective sport. Further, an accurate assessment of any asymmetries that may be present helps to decide where to start. A well-rounded strength training program can incorporate elements of both methods to optimize performance and minimise the risk of injuries.

Treatment Strategies

Physiotherapy plays a pivotal role in the management of Achilles tendinopathy. Treatment strategies focus on reducing pain, promoting healing, and improving function. These will include calf strengthening exercises, stretching routines and activity modification as frontline options. Moreover, physiotherapists can guide patients in proper footwear selection, gait retraining, and implementing preventive measures to minimize the risk of reinjury.

Rehabilitation and Prevention

Rehabilitation programs are essential for individuals recovering from Achilles tendinopathy. Gradual progression of exercise intensity, functional training, and sport-specific drills enable patients to regain strength, flexibility, and proprioception while minimizing the risk of relapse. Educating patients on proper warm-up and cool-down routines, appropriate footwear selection, and regular monitoring of training loads can significantly contribute to preventing Achilles tendinopathy in the future. One of the common errors patients make is making rehabilitation too easy, or returning to sport too quickly. Again, physiotherapy play a pivotal role in ensuring you undertake a graduated return to loading as the application of mechanical stress to the Achilles tendon promotes tendon healing and remodeling.

Conclusion

Achilles tendinopathy requires a comprehensive approach for effective management. As physiotherapists, our knowledge and expertise are invaluable in helping you overcome this condition and return to their active lifestyles.

Blood Flow Restriction – more than just a gimmick?

Blood Flow Restriction – more than just a gimmick?

by | Oct 11, 2022 | ACL, Gym and Strength, Knee, Reformer Pilates, Return to Sport

Summary:

  • Restriction of blood flow purportedly creates an internal environment of greater stress, thus greater adaptation
  • Importantly, the greater adaptation can occur with less absolute load to damaged or painful tissues
  • Started in healthy population to build muscles but the principles are transferable to rehabilitation
  • Best suited persons who are unable to tolerate normal load
  • Post surgery, tendinopathies and people needing to arrest atrophy or build muscle fast are best candidates

Blood flow restriction (BFR) training is becoming increasingly popular in rehabilitation and conditioning settings. As the name suggests, BFR training incorporates a restriction of blood to an area paired with low resistance training (20-50% of 1 rep maximum). The principle is to achieve greater muscle strength and hypertrophy gains for healthy and load-compromised populations with the same or less load than without a cuff. Essentially – more bang for your buck in the early phases of rehabilitation!

Benefits of BFR include; prevention of muscle mass in early post-operative periods, similar benefits of muscle mass and strength as heavier resistance training in achilles tendinopathies (>70% 1RM) (Centner et al, 2019), and improvement in maximum voluntary torque.

 

Whilst research is still being developed, multiple studies have been conducted recently showing the benefits of BFR training in post-operative populations ie. ACLR, patella / achilles tendinopathies, as well as knee osteoarthritis and patellofemoral pain syndrome.

Here at Praxis Physiotherapy, we have used a BFR cuff paired with low-resistance training on the reformer pilates and in the gym to optimise the distal quadriceps strength post ACL surgery. As you can see we are putting to the distal quadriceps to fatigue under a small amount of load, thus preventing muscle loss (Prue, et al. 2022) which can be common postoperatively.

General prescription guidelines according to the Australian Institute of Sport recommend that “the application of BFR should be limited to less than 20 minutes for lower limb, and 15 minutes for upper limb, before allowing adequate time for reperfusion of tissues (3 min).” (AIS, 2022).

In summary, this is an exciting new area of research that we are investigating clinically. Anecdotally, we hear from patients that they fatigue earlier in the desired muscle groups. We as a Praxis Team are embarking on some in clinic research in the area and hoping to provide feedback on our experiences so keep your eyes peeled. In the meantime, if you are pre or post your operation and are looking to maximise your recovery, come and have a chat with us about whether BFR is suitable for you!
