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?

Knee Osteoarthritis: Is ‘Bone on Bone’ a painful life sentence?

Knee Osteoarthritis: Is ‘Bone on Bone’ a painful life sentence?

by | May 16, 2023 | Knee, Osteoarthritis, Pain, Surgery

  • Knee Osteoarthritis is a common ailment responsible for pain, loss of function and reduced quality of life
  • Rates of knee OA are set to increase
  • Whilst there is no cure, exercise therapy under the guidance of a physiotherapist is considered a front line treatment to help reduce the severity of symptoms
  • There are options before a knee replacement

Do your knees go crackle and pop? Pain with walking, stairs or getting out of a chair? Stiffness and pain first thing in the morning or after a long car ride? These are signs that you may be living with the early or even advanced symptoms of knee osteoarthritis (OA). Don’t fear though – there is plenty that can be done immediately.

What is “OA”?

Osteoarthritis (OA) is an increasingly prevalent source of musculoskeletal pain and dysfunction. OA is a disease of the joint – including cartilage, bone, capsule and other associated tissues. This disease process can cause chronic pain, reduced physical function and diminished quality of life. The ageing population and increased global prevalence of obesity are anticipated to dramatically increase the impacts of knee OA and its associated impairments [1]. Although osteoarthritis can affect any joint, OA is knee is one of the most common complaints.

Presentation

It most commonly presents in people over the age of 50, and is often described as being painful, stiff and occasionally swollen. In terms of a tissue level, knee OA describes the gradual deterioration of the supportive cartilage within the knee joint. As the cartilage wears away with time, the protective joint space between the bones decreases. With a reduced cartilage lining to protect and support the spacing of the knee joint, the Femur and Tibia (knee bones) are increasingly less likely to dissipate forces through the joint . With time, it should be expected that bone spurs (osteophytes) may form in and around the joint as the bones react to repetitive contact with each other.

Management

The management of knee OA largely consists of exercises addressing strength, range of motion, quality of movement, emphasizing joint control, pain reduction and weight management.

Strength Training

Strength training should be the cornerstone of addressing knee OA, particularly the early signs. Strengthening the muscles around the knee joint, such as the quadriceps, hamstrings, and glutes provide better support to the knee, reducing stress on the joint and helping to alleviate pain and discomfort. Movement associated with exercise has an added benefit – It increases joint lubrication. Loading of the joint stimulates the production and distribution of synovial fluid within the joint. This fluid acts as a lubricant, reducing friction and providing cushioning to the joint surfaces. Improved lubrication can help alleviate pain during movement.

Range of motion

Knee osteoarthritis often leads to stiffness and limited range of motion in the joint. Physiotherapy can include specific exercises, manual therapy and stretches to improve joint flexibility, helping to restore a more normal range of motion and enhancing mobility. The greater the restoration of range, the better the knee feels.

Pain reduction

Both strength training and physiotherapy can help reduce pain associated with knee OA. As mentioned, stronger muscles provide better support to the joint, relieving pressure and reducing pain during movement. Physiotherapy may provide education of aggravating and easing factors (eg. hot / cold packs, hydrotherapy) as well as liaise with your GP for adequate analgesic medications.

Lifestyle modifications

Adopting a healthy lifestyle can play a pivotal role in managing knee osteoarthritis. Maintaining a healthy weight reduces the stress on the knee joints. Regular low-impact exercises such as swimming, cycling and reformer pilates help improve strength, flexibility, and overall joint health. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can promote weight loss and provide essential nutrients for joint health. Quitting smoking and minimizing alcohol consumption are also beneficial.

Improved weight management

Regular exercise can assist in weight management, which is crucial for individuals with knee osteoarthritis. Excess weight puts additional strain on the knee joint, contributing to pain and progression of the condition. By maintaining a healthy weight, exercise helps to reduce the load on the joint and alleviate pain.

Surgical Interventions

When conservative measures fail to provide relief, surgical interventions may be necessary. Procedures such as arthroscopy, osteotomy, and joint replacement surgery can help repair damaged tissues, realign the joint, or replace the damaged joint with a prosthetic. These surgeries can significantly improve mobility and reduce pain, allowing individuals to resume their daily activities. Physiotherapy can aid in preparing you for the surgery, as well as rebuild your “new” knee after a knee replacement has been completed.

In conclusion, while knee osteoarthritis can be challenging, it is not a condition that should hinder individuals from leading fulfilling lives. By implementing lifestyle modifications, exploring various treatment options, and working closely with your physiotherapist, individuals can effectively manage their symptoms, alleviate pain, and enjoy an active lifestyle with a sense of well-being. If conservative options fail, there are surgical interventions that can be investigated. If you are wanting to look after your knees, or already suffering from knee pain, chat to our knowledgeable Praxis Physios to discuss your treatment options at any stage of OA’s progression.

Knee Pain

Knee Pain

by | Jan 7, 2020 | Knee, Pain

Do you have a good knee and a bad knee? Do your knees snap, crackle and pop? Do you ever wish you could walk for longer without pain or not be worried about how your knees will feel in the morning if you were living your life to the fullest? Knee pain is a very common condition that affects people of all ages. Typically knee pain is the result of an injury on the sporting field when we are younger but tend to be more degenerative in nature as we age.
Mid Potion Achilles Tendinopathy Location

Different knee injuries tend to have differing symptoms. Common symptoms include:

  • Aching, sharp, stabbing and/or catching pains
  • Large amounts of swelling or sometimes pockets of swelling
  • Warm to touch
  • Feelings of grating, grinding or even giving way
  • Pops and crunching noises
  • Unable to full bend or straighten the knee

The structures of the knee that are often implicated in knee pain are the patellar or quadriceps tendons, cartilage, meniscus, bursas, and even major ligaments such as the anterior cruciate ligament, otherwise known as the ACL.

Common injuries to the knee can be:

  • Osteoarthritis
  • Tendinopathy / Tendonitis
  • Bursitis
  • Knee cap pain (patellofemoral pain)
  • Meniscal tear (degenerative and acute tears)
  • Dislocated knee cap
  • Iliotibial band friction syndrome

Regardless of your symptoms and presentation, our highly trained Praxis physiotherapists have expertise in this area and will help identify the problem and work with you so that you will feel empowered to fix the problem. At Praxis Physio this is our point of difference, we promise to take the time to fix you using a range of modalities including advice, hands on manual therapies and of course strength and conditioning programming. In addition, we work in close collaboration with leading knee surgeons if this course of action is required.

FACT OR FICTION FRIDAY || Knee Pain and Scans

FACT OR FICTION FRIDAY || Knee Pain and Scans

by | Dec 6, 2019 | Knee, Osteoarthritis, Pain

Answer: FICTION 🙊

“Osteoarthritis” is a common term that gets used by our patients as an explanation of their knee pain. But is this always the case 🤔?

🔍In a recent systematic review estimates of osteoarthritis feature prevalence on MRI among asymptomatic uninjured knees were up to 14% in adults < 40 years, and up to 43% in adults > 40 years!

Whilst features on MRI imaging such as cartilage defects, meniscal tears and osteophyte lesions can potentially play a role if you have pain, this should always be interpreted in the context of your clinical presentation by a health care professional as these changes can be normal in an asymptomatic population – just like grey hair as we age 👴👵!

If you have knee pain and have resigned yourself to a ‘life sentence’, come and have a chat to one of our physios to ensure you aren’t robbing yourself of a full functioning future 🕺🏃🏌️🏄🏋️🏊🚴🏂🎾! Call 07 3102 3337 or book online
