Osteoarthritis — Hip and Knee

Osteoarthritis gradually wears down joint cartilage, causing pain, stiffness, swelling, and reduced mobility. Physiotherapy and regenerative treatments help manage symptoms, improve function, and support joint health.

Understanding Osteoarthritis

Osteoarthritis (OA) is the most prevalent long-term joint condition, often called ‘wear-and-
tear’ arthritis. It is a progressive degenerative disorder leading to breakdown of joint cartilage
and eventual impact on surrounding bones, ligaments, and muscles. It most commonly
affects the hips and knees, and is strongly linked to age, obesity, prior joint injury, and
genetics.

Causes

  • Natural wear and tear over time
  • Previous joint injury or surgery
  • Aging and cartilage degeneration
  • Obesity and lack of physical activity
  • Genetic predisposition
  • Underlying medical conditions

Symptoms

  • Pain or aching after extended activity or at the end of the day
  • Morning stiffness or stiffness after resting
  • Reduced range of motion
  • Clicking or cracking sounds when bending a joint
  • Swelling and tenderness around the affected joint
  • Muscle weakness and joint instability

Treatment

While OA cannot be cured, physical therapy is vital in managing pain and maintaining function. Treatment includes joint mobilisation, muscle strengthening, manual therapy, balance training, gait retraining, and pain management strategies.

Specialist & Regenerative Medicine Options

Osteoarthritis is one of the most extensively studied indications for regenerative medicine. At Prestidge, our sports and exercise physicians offer a range of evidence-informed treatments that may assist with pain management, support joint health, and improve quality of life — often as part of a broader plan to delay or avoid surgical intervention. All treatments are subject to individual clinical assessment.
  • Platelet Rich Plasma (PRP) Therapy — Concentrated platelets from your own blood are injected into the affected joint under image guidance, providing growth factors and anti-inflammatory agents that may support joint health and pain management.
  • Hyaluronic Acid (Viscosupplementation) — Products such as Synvisc or other hyaluronic acid formulations are injected into the joint to help restore the lubricating properties of synovial fluid, which may reduce discomfort and improve mobility in suitable patients.
  • Stem Cell Therapy — Where clinically appropriate and within current TGA regulatory guidelines, autologous mesenchymal stem cells derived from bone marrow or adipose tissue may be used as part of a personalised treatment plan.
  • Combination PRP + Hyaluronic Acid — Where indicated, combining these two approaches may offer complementary effects for joint support and symptom management.
  • Intra-osseous (Bone) Injections — Targeted injections for patients where subchondral bone changes are identified as a contributing factor to symptoms.
  • Corticosteroid Injections — Used selectively for short-term symptom management to allow rehabilitation to progress.
  • Testosterone Replacement Therapy (TRT) — For patients with clinically confirmed low testosterone contributing to reduced recovery capacity, muscle weakness, or quality of life, our physicians can assess suitability for TRT. This prescription treatment is available only after comprehensive pathology review and medical assessment and is not appropriate for all patients.
  • Peptide Therapy — Certain peptides, prescribed by our sports and exercise physicians where clinically appropriate, may support tissue repair, reduce inflammation, and assist recovery as part of a comprehensive management plan. All peptide treatments require a valid prescription following individual medical assessment in accordance with TGA and AHPRA requirements.

Our sports and exercise physicians at Prestidge work alongside your treating clinician to determine which option best suits your condition, goals, and stage of injury. Image-guided procedures are performed with precision and care. Visit prestidge.com.au to learn more about our full range of specialist services.

Important: All specialist consultations, prescription treatments, and injectable procedures are subject to individual clinical assessment by a registered medical practitioner. Suitability, potential benefits, and risks will be discussed during your consultation. No treatment outcomes are guaranteed. Prescription medicines — including testosterone and peptide therapies — are only available following appropriate medical review and a valid prescription in accordance with TGA and AHPRA requirements.

Prevention Tips

Maintain a healthy weight, stay active with low-impact exercise (swimming, cycling, walking), and practice good posture. Regular strength and flexibility training protects joints from excessive wear.
