Navigating Knee Osteoarthritis: A Physio-Centric Pathway to Strength and Mobility Before Surgery

Navigating Knee Osteoarthritis: A Physio-Centric Pathway to Strength and Mobility Before Surgery

by | Apr 22, 2025 | Knee, Reformer Pilates

Knee osteoarthritis (OA) is one of the most common causes of chronic pain and mobility restriction in Australians over 45. Whether you’re a weekend warrior, an active grandparent, or someone just trying to keep up with the daily demands of life, OA can slowly erode your confidence in movement — long before X-rays show the full extent of joint degeneration.

At Praxis Physiotherapy, we take a forward-thinking, collaborative approach to managing knee OA. Working closely with renowned orthopaedic knee surgeon Dr. Kelly Macgroarty and drawing from our extensive experience with high-performance athletes and everyday patients alike, we believe the journey toward better knees starts well before surgery — and, for many, might even avoid or delay it altogether.

What is Knee Osteoarthritis?

Knee OA is a progressive condition involving the breakdown of joint cartilage and underlying bone, typically leading to:

  • Pain during or after activity

  • Morning stiffness or stiffness after rest

  • Swelling and inflammation

  • Loss of flexibility and range of motion

  • Difficulty with stairs, kneeling, or prolonged standing

Radiographic OA becomes more common with age, but symptoms often precede visible changes on X-ray. Up to 30% of people over 65 show radiographic OA, yet many remain functionally capable — highlighting the importance of early, movement-based interventions (Naja et al., 2021).

Why a Physio-Led Model Before Knee Replacement?

Surgery is not the first or only option. A large systematic review of 19 randomized controlled trials found that non-surgical interventions such as physiotherapy, platelet-rich plasma (PRP), and structured exercise were associated with meaningful improvements in pain and function over 12 months (Naja et al., 2021). Physiotherapy, in particular, is consistently supported by international guidelines as a first-line treatment (Fransen et al., 2015; Bennell et al., 2014).

Traditionally, knee OA rehab has emphasised quadriceps strengthening — and for good reason, as quadriceps weakness is strongly linked to OA-related pain and disability. However, more recent research suggests that focusing exclusively on the quadriceps may be too narrow. Programs that include hip (gluteal), hamstring, and calf muscle strengthening are now shown to be superior in improving functional outcomes, especially for activities like walking, stair climbing, and maintaining balance (Bennell et al., 2014). This broader approach addresses the full kinetic chain around the knee, optimises joint load distribution, and better supports long-term movement efficiency.

At Praxis, our physios:

  • Assess gait, strength, joint mobility, and function

  • Design individualised exercise programs targeting quadriceps, glutes, and calf strength

  • Implement manual therapy techniques to restore joint mobility

  • Provide pain education, load management advice, and real-world strategies

  • Monitor progress and adjust programs over time

This proactive approach not only builds resilience in the knee but also prepares the joint and surrounding muscles should surgery eventually be required.

Booster Sessions: Keeping Gains, Lowering Costs

An often-overlooked strategy is the use of booster physiotherapy sessions — structured follow-ups after an initial rehab program. Research by Bove et al. (2018) showed that exercise programs with booster sessions at 3, 6, and 12 months were not only more clinically effective but also more cost-effective over a two-year period compared to standard physiotherapy care.

At Praxis, we now embed these booster sessions into long-term OA management. They help patients:

  • Maintain strength and conditioning gains

  • Stay accountable with home programs

  • Troubleshoot new symptoms early

  • Reduce future health care costs and medication reliance

What About Injections and Other Adjuncts?

We often collaborate with GPs and orthopaedic specialists to incorporate adjunct treatments where the evidence supports it:

  • Platelet-rich plasma (PRP) injections showed significant long-term benefit for pain and function, with improvements of ~20 points on the WOMAC index. PRP ranked just behind stem cells as the most effective non-surgical treatment in a large 2021 network meta-analysis (Naja et al., 2021).

  • Hyaluronic acid (HA) injections have shown mixed results. A review of overlapping meta-analyses concluded that HA is likely safe and modestly effective, especially in early-stage OA, although guideline recommendations remain inconsistent (Xing et al., 2016).

Ultimately, our philosophy is to build strong knees first, and complement physiotherapy with interventions like PRP or HA only when clinically indicated and appropriately timed.

Surgical Collaboration 

In more advanced cases, where conservative management fails, we work closely with Dr. Kelly Macgroarty, one of Queensland’s leading knee surgeons. Our relationship allows:

  • Streamlined triage for surgical consultation

  • Shared prehabilitation planning to improve surgical outcomes

  • Integrated post-operative rehab, using in-clinic gym equipment and reformer Pilates to accelerate return to function

This continuity ensures you’re never left navigating knee OA alone — whether your journey stays entirely within physio care or progresses to surgical management.

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?

Capping kneecap pain – Your guide to Anterior Knee Pain (Patellofemoral Pain Syndrome)

Capping kneecap pain – Your guide to Anterior Knee Pain (Patellofemoral Pain Syndrome)

by | Jul 11, 2023 | Knee, Return to Sport, Running Injuries

Patellofemoral Pain Syndrome (PFPS) is a common condition that affects the knee joint, particularly the area where the kneecap (patella) meets the thigh bone (femur). It is a prevalent issue among athletes, active individuals, and people with certain anatomical factors. In this Praxis What You Preach article, we will explore PFPS, its causes, symptoms, and available treatment options, shedding light on how physiotherapy can effectively manage and alleviate this condition.

What is PFPS?

Patellofemoral Pain Syndrome, also known as runner’s knee or anterior knee pain, occurs when the patella fails to glide smoothly over the femoral groove during knee movement. This causes irritation and inflammation in the patellofemoral joint, specifically the underlying bone, leading to pain, discomfort, loss of function and even swelling. PFPS can be triggered by multiple factors, such as overuse, muscle imbalances, poor biomechanics, weak hip and thigh muscles, improper footwear, and previous knee injuries. Essentially though it is the kneecap joints’ in ability to tolerate the load of the activities being undertaken.

Symptoms and Diagnosis

Common symptoms of PFPS include pain around or behind the patella, especially during activities that involve knee squatting, lunging, bending, climbing / descending stairs, or sitting for extended periods with knees bent (commonly called movie goers knee). These typically can occur when workloads have increased with activities such as running, cycling or weightlifting. Patients may also experience swelling, grinding or even stabbing sensations, and occasionally a feeling of knee instability. A physiotherapist will perform a comprehensive evaluation, considering the patient’s medical history, conducting a physical examination, and possibly using imaging tests, to accurately diagnose PFPS and rule out other potential causes of knee pain.

Treatment and Management

Physiotherapy plays a crucial role in managing and treating PFPS. The primary goal of physiotherapy is to exclude differential diagnoses, alleviate pain, improve knee function, manage aggravating workloads and prevent the recurrence of symptoms. Treatment plans are tailored after a comprehensive history taking and examination to the individual’s specific needs and should include the following components:

  • Pain Management: Initially, pain and inflammation may be managed through ice therapy, massage, stretching and non-steroidal anti-inflammatory drugs (NSAIDs).
  • Strengthening Exercises: Targeted exercises aim to strengthen the hip, thigh, and trunk muscles, which can help correct muscle imbalances and improve knee alignment and load tolerance.
  • Stretching and Flexibility: Stretching exercises can help improve flexibility in the muscles surrounding the knee joint, reducing strain on the patellofemoral joint.
  • Biomechanical Analysis: A physiotherapist may evaluate the patient’s movement patterns during functional activities such as jumping and running to identify any obvious faulty mechanics that contribute to PFPS. Corrective techniques, gait retraining may be employed.
  • Activity Modification and Rehabilitation: A gradual return to activities while maintaining a balance between rest and exercise is important to ensure proper healing and prevent re-injury.
  • Taping: taping has been shown to acutely help reduce symptoms by aiding in the improvement of kneecap tracking through the femoral trochlea (groove where the kneecap runs)

Prevention Strategies

To prevent the onset or recurrence of PFPS, individuals can incorporate the following strategies:

  • Regular strength and conditioning exercises to maintain muscle balance and strength of the lower limbs and trunk musculature.
  • Proper warm-up and cool-down routines before and after physical activities.
  • Gradual progression of activity levels and intensities to avoid overuse injuries.
  • Being aware of the early signs and symptoms and addressing them promptly.

Is my knee pain osteoarthritis?

In short, No. Patellofemoral Pain Syndrome (PFPS) is not the same as Patellofemoral Joint (PFJ) Osteoarthritis (OA). While both conditions involve the patellofemoral joint, they are distinct entities with different causes and characteristics. As mentioned, PFPS primarily involves pain and dysfunction in the patellofemoral joint, often caused by factors such as overuse, muscle imbalances, or poor biomechanics. It is commonly seen in younger athletes and active individuals. PFPS is characterized by pain around or behind the patella, especially during activities that involve knee bending or loading such as running.

On the other hand, PFJ OA refers to the degeneration and wearing down of the cartilage within the patellofemoral joint. This condition typically occurs in older individuals and is more common in those with a history of knee injuries or conditions such as patellar instability. The primary symptom of patellofemoral joint osteoarthritis is joint pain, stiffness, and swelling, which worsen over time. This pain can be at rest.

While both conditions can cause knee pain and affect the patellofemoral joint, the underlying mechanisms and treatment approaches differ. Physiotherapy plays a crucial role in managing both conditions, but the specific treatment plans and exercises may vary based on the individual’s diagnosis, symptoms, and physical examination findings.

In summary, Patellofemoral Pain Syndrome is a common knee condition that can significantly impact an individual’s daily activities. With a comprehensive physiotherapy approach involving pain management, strengthening exercises, and biomechanical analysis, PFPS can be effectively managed and treated, allowing individuals to regain pain-free movement and engage in their desired activities.

Stress Fractures in Young Cricket Fast bowlers: A persistent challenge

Stress Fractures in Young Cricket Fast bowlers: A persistent challenge

by | May 16, 2023 | Lower Back, Return to Sport

Lumbar stress fractures are a common and persistent injury among cricket fast bowlers, particularly adolescents. The repetitive and high-intensity nature of the bowling action places tremendous stress on the lower back, leading to the development of stress fractures in the lumbar vertebrae. With several years of cricket physio experience, I’ll explore the causes, symptoms, treatment, and prevention strategies associated with these usually season ending injuries.

Causes and Symptoms:

The primary cause of lumbar stress fractures in fast bowlers is the high volumes of repeated hyperextension and rotation of the lower back during the bowling action. This repetitive motion places excessive strain on the bony structures of the spine (pars interarticularis), eventually leading to small cracks or fractures. Adolescent fast bowlers are of particular risk as this strut of bone has yet to fully develop (as with most of their surrounding musculature) and thus is more susceptible to overload. Symptoms of lumbar stress fractures may include lower back pain, stiffness, tenderness, and discomfort, particularly during bowling.

Treatment and Rehabilitation:

The management of lumbar stress fractures requires a comprehensive approach. Initially, rest and avoiding activities that exacerbate the pain are essential to allow the bone to heal. A period of complete rest from bowling, coupled with appropriate pain management is usually recommended. A structured rehabilitation program focusing on core stability, flexibility, and strengthening exercises on the lumbar spine, pelvis and lower limbs is crucial for a safe return to bowling. Once a players has reestablished the requisite physical attributes, a graduated bowling plan is established.

Prevention Strategies:

Prevention is key in mitigating the risk of lumbar stress fractures. Fast bowlers should maintain a balanced training regime that includes multi-joint strength training, flexibility exercises, and proper warm-up and cool-down routines. Regular monitoring of workload and ensuring adequate recovery time between bowling spells can also minimize the likelihood of injury. Of particular note, is avoiding back to back days of fast bowling in adolescent cricketers.

In summary, lumbar stress fractures pose a significant challenge to cricket fast bowlers, especially those in their teen years or as they transition to junior cricket to senior cricket. A diagnosis typically requires extensive time away from bowling and requires a targeted rehabilitation plan and a cautious return to the sport. By understanding the causes, recognizing the symptoms, and implementing effective prevention and strengthening strategies, bowlers can continue to bowl fast and trouble the batsmen down the other end!

If you wanting to minimise your risk of a stress fracture, or think you may have one, feel free to consult with one of our expert physiotherapists, well versed in the cricket literature.

FACT OR FICTION FRIDAY || I’m too old to lift weights!

Answer: FICTION 🙊 Progressive strength training in the elderly (>60 years) is efficient, even with higher intensities, to improve bone health, pack on muscle and retain function. And not surprisingly, side effects are rare! Strength training increases muscle strength by increasing muscle mass, and by improving the recruitment of motor units, and increasing their firing rate. This is no different between younger and older gym goers.
Mid Potion Achilles Tendinopathy Location

It all comes down to how you train! Training with higher loads generally provokes marginally larger gains in muscle size. Intensity corresponding above 85% of the individual maximum voluntary strength can also illicit improved rate of force development compared to 60-80%. This is imperative for reducing frailty as we age.

It is now recommended that healthy old people should train 3 or 4 times weekly for the best results; persons with poor performance at the outset can achieve improvement even with less frequent training.

So if you are using age as an excuse – STOP! Don’t let your age be a barrier to trying new things or feeling strong. We are here to help with supervised sessions, a great network of PTs as well as our clinical reformer pilates classes which are a great way to start (or return) to strength training!
