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

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

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?

Pilates: Reforming our back pain rehabilitation (Part 1 of 3)

Pilates: Reforming our back pain rehabilitation (Part 1 of 3)

With our 30 day pilates challenge starting today, we thought we would take a look at why we love pilates so much for our patients, and what some of the benefits are. Part 1 looks at how pilates affect those with chronic lower back pain. Part 2 looks at the difference between mat and reformer pilates and part 3 looks at how often is required to see the benefit of pilates.

SUMMARY:

  • Back pain is extremely common, multifactorial, and often reoccurs
  • Strengthening interventions appear better for long term suffers of lower back pain
  • Pilates has been shown to improve muscular strength and endurance of key pelvic and postural musculature associated with lower back pain
  • Specifically, pilates promotes the restoration of the function of muscles involved in lumbopelvic stabilisation, that is, transversus abdominis, multifidus, diaphragm and pelvic floor muscles
  • As little as 2 sessions per week for 6 weeks has been shown to see improvements in pain and function for those with longstanding lower back pain, even after stopping pilates

Chronic low back pain (CLBP) is one of the commonest musculoskeletal problems in modern society (Anderson 1999) and is a highly prevalent in both the sporting and general public. CLBP is experienced by 70%–80% of adults at some time in their lives (Crombez et al 1999) and as such, the costs associated with LBP and related disability are enormous, causing a major economic burden for patients, governments and health insurance companies (Dagenais 2008).

Lower back pain has been one of the most extensively studied musculoskeletal conditions as a result of the prevalence and debilitation nature. Its management comprises a range of different intervention strategies including surgery, drug therapy and non-medical intervention like rehabilitation (Paolucci et al 2018). Within Physiotherapy, exercise therapy is probably the most commonly used intervention for the treatment of patients with chronic non-specific LBP due to its plausible biological rationale and low cost.

Whilst general conditioning programs to train strength and endurance of the spine musculature have been shown to reduce pain intensity and disability (Rainville et al 2004), the popularity of pilates (both mat and reformer) has helped provide an accessible and supervised form of therapeutic exercise.

EVIDENCE FOR PILATES

The Pilates method, using functional exercises aims to improve muscular strength and endurance. Specifically, the pilates method have promotes the restoration of the function of muscles involved in lumbopelvic stabilisation, that is, transversus abdominis, multifidus, diaphragm and pelvic floor muscles. Using the principles of progressive overload, your body adapts to the incremental loading week after week and consequently results important postural control improvement. In 2009, Curnow and colleagues showed that the Pilates method improves load transfer through the pelvis, something that intuitively helps those with CLBP.

However, a systematic review (Patti et al 2015) reported evidence that Pilates method-based exercises are more effective than no treatment or minimal physical exercise interventions in the management of chronic nonspecific LBP. Further, they pointed out that the effects of the Pilates method are only proven for patients with chronic nonspecific LBP in the short term.

A recent study by Natour and colleagues (2015) showed that the group of participants that were practicing Pilates method resulted statistically better compared with the a non exercising group who only used inflammatory medication. Those who were in the pilates group used less pain medication at 45, 90 (conclusion of the Pilates method), and 180 days, 90 days after the conclusion of the exercise program.

In conclusion, Pilates as an exercise choice is more effective than minimal physical exercise or drug based interventions in reducing pain and disability in the short-term period. There is agreement that exercise “helps” in the treatment of chronic pain, but it is still not clear exactly which factors or particular kind of exercises may be responsible of such improvements (Natour et al 2015; Patti et al 2015). Praxis Physiotherapy has always been a strong proponent of movement and loading early in rehabilitation (more on this in later blogs!).

In the next instalment, we discuss the difference between mat and reformer pilates and perhaps find some more answers regarding which exercise regime reigns supreme!

Congratulations 30 Day Challengers

Congratulations 30 Day Challengers

Final measures have been taken. Numbers crunched and the results are in…

But first, a massive congratulations to all our 30 Day Challengers who recently completed a gruelling but rewarding 30 days of Reformer Pilates. Participants completed a suite of baseline strength measures (recording maximum repetitions) on the reformers and then underwent a structured program devised by our clinical Pilates guru’s Emma, Karen and Kylie. No two workouts were the same and challengers used their 20 classes over the 30 days to take giant strides in improving their pilates technique and strength.

We had an eager and wide range of participants from the sporting to the previously sedentary office worker. All participants have reported how strong they feel after only a month with further benefits felt in enhanced posture and energy levels.

During this challenge, our participant’s average improvement to their baseline testing was more than 80%! Special mentions to Dominique P, whose push ups went from 15 to 43 repetitions. Sandra L doubled her ab curl ups to record the highest measure of 120 reps and increased her scooter lunge a whopping 55 reps!

But there can only be one winner from each clinic. Our winners were *drumroll please* Michael B. from Club Coops Carseldine and Siobhan E. from the X-Centre in the Valley. Michael in particular blew the competition away with calf raises progressing from 38 to 105 reps, footwork (on all springs) from 40 to a mammoth 120 reps! Not to be outdone, Siobhan almost doubled her abdominal curls to 118 and added almost 40 reps to her Scooter lunge!

Michael and Siobhan each receive a FREE 5-Pack as a reward for effort and dedication during the colder months of the year! Great stuff!!

Congratulations again to all our participants and our winners Michael and Siobhan. Stay tuned for the next challenge date which we’ll have a few added surprises and bonuses included!

Yours in Health,

Praxis Pilates – Prevent. Prepare. Perform.
