Managing Knee Arthritis: An Allied Health Perspective
Knee arthritis is one of the most common musculoskeletal conditions in Australia. By some estimates, one in five Australians over the age of 45 lives with some form of osteoarthritis, and the knee is the most frequently affected joint. It changes the way people walk, work, exercise, sleep and move through their daily lives.
Managing knee arthritis well is rarely about a single treatment. It is about the right team of people supporting the right combination of approaches over time. This blog explains where allied health fits in that picture, how physiotherapy, exercise physiology and podiatry each contribute, and how to know when it is time to bring in additional medical or specialist input.
It is written for adults living with knee arthritis (both NDIS participants and community members), for family members supporting someone through it, and for Support Coordinators considering allied health input for participants with knee arthritis alongside other disability-related needs.
For a broader clinical overview of conservative treatment options, our conservative treatments for knee arthritis page covers the medical and clinical detail. This blog focuses on the allied health perspective specifically.
What Is Knee Arthritis?
Arthritis is a broad term for joint inflammation. The knee is a hinge joint that carries the body's full weight with every step, so it is particularly vulnerable to wear, injury and inflammation over time.
The most common forms of knee arthritis are:
Osteoarthritis, the wear-and-tear form. Cartilage inside the joint gradually breaks down, and the underlying bone changes over time. It typically progresses slowly across years and is more common with age, previous injury, higher body weight and genetic predisposition.
Rheumatoid arthritis, an autoimmune condition where the body's immune system attacks the joint lining. This form typically affects multiple joints, requires specialist rheumatology input and is often managed with disease-modifying medication.
Post-traumatic arthritis, which develops after a significant knee injury such as an ACL tear, meniscus tear or fracture.
The type of arthritis matters, because the treatment approach differs. This blog focuses primarily on osteoarthritis, which is the type most often managed with a conservative allied health approach.
The Allied Health Perspective on Knee Arthritis
Medical management of knee arthritis (medications, injections, and when appropriate, joint replacement surgery) sits with GPs, rheumatologists and orthopaedic surgeons. Allied health sits alongside that medical care.
The allied health question is different. It is not "how do we treat the disease?" It is: how do we help this person keep moving, stay strong, manage pain, and continue doing the things that matter to them?
For most people with knee arthritis, allied health input is what makes daily life sustainable between medical appointments. The evidence base is clear: exercise, strengthening, weight management and joint-friendly movement patterns produce better long-term outcomes than rest, avoidance and passive treatment.
Physiotherapy for Knee Arthritis
Physiotherapy is often the primary allied health input for knee arthritis. A physiotherapist assesses the joint, the surrounding muscles, movement patterns and functional impact, then designs a treatment plan tailored to the person's goals and daily life.
Typical physiotherapy input includes:
- Assessment of joint range, strength, alignment, pain patterns and functional limitations.
- Manual therapy to reduce pain and improve joint mobility, including soft tissue work and gentle joint mobilisation.
- Exercise prescription focused on strengthening the muscles that support the knee, particularly the quadriceps, hamstrings, glutes and calves.
- Movement retraining to reduce load on the knee during walking, stairs, sit-to-stand transitions and other daily activities.
- Pain management strategies including pacing, activity modification and self-management education.
- Equipment recommendations such as walking aids where appropriate.
Physiotherapy for knee arthritis is often more effective when it happens in the person's real environment, particularly for older adults where stairs, kitchens and outdoor mobility are the priority. AH2U delivers mobile physiotherapy across Sydney and Greater Sydney for exactly this reason.
Exercise Physiology for Knee Arthritis
An Accredited Exercise Physiologist (AEP) takes the strengthening and conditioning work further with structured, progressive exercise programmes. For knee arthritis, the goal is building strength, cardiovascular fitness and functional capacity in a way that protects the joint rather than aggravating it.
Exercise physiology for knee arthritis typically includes:
- A tailored exercise programme that progresses over time, based on the person's starting point and goals.
- Land-based exercise including strength training, cardiovascular work and mobility exercises.
- Water-based exercise (hydrotherapy) where available, which is particularly valuable for people with significant pain, deconditioning or higher body weight.
- Weight management support where relevant. Even modest weight loss significantly reduces load on the knee.
- Ongoing coaching to keep the programme sustainable.
The evidence for exercise as a treatment for knee osteoarthritis is strong. It is not an adjunct to real treatment. It is real treatment.
Podiatry for Knee Arthritis
Podiatry is often the missing piece in knee arthritis management. Foot biomechanics directly affect knee load. Poor gait mechanics, foot pronation, leg-length differences and worn footwear all contribute to how much stress the knee absorbs with every step.
A podiatrist can:
- Assess gait and biomechanics to identify factors that increase knee load.
- Prescribe orthotics where they are clinically indicated (they are not for everyone).
- Advise on footwear appropriate to the person's activities and knee arthritis stage.
- Address related foot issues that may be affecting walking patterns, such as heel pain, forefoot pain or nail conditions that limit mobility.
For people whose knee arthritis is affected by biomechanical factors, podiatry input can meaningfully change pain levels and function.
How the Allied Health Disciplines Work Together
Knee arthritis rarely benefits from one discipline in isolation. A typical coordinated approach might look like:
- The physiotherapist leads the initial assessment and pain management, working on joint mobility, strength and daily function.
- The exercise physiologist takes on progressive strengthening and cardiovascular conditioning, particularly for people who want to build capacity beyond basic function.
- The podiatrist addresses biomechanical factors and footwear.
- The GP oversees medication, refers to specialists as needed and monitors overall health.
- The rheumatologist or orthopaedic surgeon steps in for cases requiring specialist medical input, injections or surgical consultation.
When these disciplines are coordinated, the person benefits from the full picture. When they work in isolation, gaps appear.
For NDIS Participants With Knee Arthritis
For NDIS participants, knee arthritis is often part of a broader picture that includes disability, ageing, or multiple conditions. Physiotherapy, exercise physiology and podiatry for knee arthritis can be funded under Capacity Building, Improved Daily Living or Improved Health and Wellbeing, depending on the plan and goals.
The work often integrates with other allied health input. A participant receiving Occupational Therapy for daily living support may also benefit from physio and exercise physiology for knee arthritis, coordinated across the AH2U team so the participant is not managing three separate providers.
For older NDIS participants or participants ageing with disability, knee arthritis is a common comorbidity worth addressing before it significantly limits mobility.
For Community Clients With Knee Arthritis
For community members not funded through the NDIS, AH2U delivers physiotherapy, exercise physiology and podiatry privately or through relevant health rebate schemes such as Medicare Chronic Disease Management (Team Care Arrangements) and private health fund extras cover.
A typical starting point is a GP visit to confirm the diagnosis, discuss overall management and consider a Chronic Disease Management referral if appropriate. From there, the allied health work begins.
When to Seek Medical Rather Than Allied Health Input
Allied health is powerful, but it is not the whole answer. Reasons to see a GP, rheumatologist or orthopaedic surgeon include:
- Sudden significant increase in pain, swelling or joint deformity.
- Symptoms in multiple joints suggestive of an inflammatory arthritis.
- Pain that does not respond to conservative management over a reasonable period.
- Increasing disability that is affecting quality of life significantly.
- Consideration of injections, disease-modifying medication or surgical options.
A good allied health team will encourage medical input alongside the conservative work, not replace it.
