PRP cannot cure hip arthritis, but for suitable patients with mild to moderate osteoarthritis it may help reduce pain and improve function as part of a broader management plan.
Hip arthritis is a condition that gradually robs people of mobility, comfort, and independence. Groin pain, a limp, and difficulty putting on shoes or getting in and out of a car are common complaints. These symptoms can severely affect quality of life. Yet many patients are not yet ready for hip replacement surgery. For them, there is a meaningful gap in treatment options.
This guide is for patients with hip arthritis in Sydney’s north-west and the Southern Highlands. It explains what is happening in the joint and what the treatment options are. It also looks at whether regenerative therapies like PRP might play a role in their care.
Understanding Hip Osteoarthritis
The hip is a ball-and-socket joint — the ball (femoral head) sits within the socket (acetabulum) of the pelvis. Both surfaces are covered with articular cartilage, which allows smooth, pain-free movement. In osteoarthritis (OA), this cartilage progressively breaks down. The joint space narrows, bone spurs (osteophytes) form, and the joint lining (synovium) becomes chronically inflamed.
Hip OA affects roughly 10% of adults over 60. It can occur earlier too, particularly after hip injuries, with developmental conditions like hip dysplasia, or in people with a family history of the condition.
Symptoms of Hip Arthritis
- Groin pain — the most characteristic location for hip OA pain; also common in the outer hip, buttock, or thigh
- Morning stiffness that eases within 30 minutes of getting up and moving
- Reduced range of motion — particularly difficulty rotating the hip inward and outward
- Pain with weight-bearing activities — walking, standing, climbing stairs
- A limp, which may develop gradually as the body compensates for pain
- Pain at rest in more advanced stages, including at night
Diagnosing Hip Arthritis
Diagnosis is made through a combination of clinical assessment and imaging. X-rays typically show joint space narrowing, subchondral sclerosis, and osteophytes in moderate to advanced OA. MRI can identify earlier changes and other coexisting pathology such as labral tears or bone oedema.
It is important to accurately diagnose the cause of hip pain. Groin pain can also arise from the lumbar spine, the hip flexor tendons, the adductor muscles, or the hip labrum. Each of these requires different management.
Conventional Treatment
- Exercise and physiotherapy — the most evidence-backed first-line treatment; strengthening the hip and core muscles reduces load on the joint and improves function
- Weight management — each kilogram of weight loss reduces the force through the hip during walking by several kilograms
- Pain relief medications — paracetamol and NSAIDs for pain management; used with caution given gastrointestinal and cardiovascular risks with long-term NSAID use
- Walking aids — a walking stick in the contralateral hand can significantly reduce hip joint load
- Cortisone injection — provides short-term pain relief and can help confirm the hip joint as the source of pain; duration of benefit is variable and typically 6–12 weeks
- Total hip replacement (THR) — highly effective surgery for end-stage hip OA; indicated when conservative measures have failed and quality of life is significantly impaired
The Treatment Gap for Moderate Hip Arthritis
Many patients find themselves in a frustrating middle ground. Their hip OA causes significant pain and functional limitation. But they are either too young for a hip replacement, not ready for surgery, or do not yet meet the clinical threshold for it. Cortisone injections provide temporary relief that becomes shorter-lived over time. NSAIDs carry too many risks for long-term use.
This is the population for whom regenerative medicine offers a meaningful option.
PRP for Hip Osteoarthritis
PRP therapy for hip arthritis involves injecting a concentration of your own platelets directly into the hip joint. These platelets are rich in growth factors, and the injection is performed under ultrasound or fluoroscopic guidance. The growth factors work to reduce synovial inflammation, support the joint environment, and potentially slow the progression of cartilage breakdown.
Clinical evidence for PRP in hip OA is growing. Studies show improvements in pain and function comparable to, and in some cases better than, cortisone injections. This advantage is clearest at longer follow-up timepoints. PRP carries no systemic side effects and does not accelerate joint deterioration, unlike some other interventions.
PRP is not a cure for hip arthritis and will not reverse established structural changes. However, some patients want to maximise function, delay surgery, and use a treatment that works with their body’s biology rather than simply masking symptoms. For them, it is a well-reasoned choice.

Frequently Asked Questions
Can PRP help hip arthritis?
PRP is used to help manage symptoms of mild to moderate hip osteoarthritis by targeting inflammation and supporting the joint environment. It is not a cure for arthritis, but for suitable patients it may help reduce pain and improve function as part of a broader management plan.
Is PRP an alternative to hip replacement?
PRP is not a replacement for surgery in advanced arthritis. It is generally most useful in earlier stages, or where a patient wishes to explore non-surgical options first. Suitability is determined after assessment of your imaging and symptoms.
How many PRP injections are needed for hip arthritis?
This depends on the severity of the arthritis and your response to treatment. Some patients have a single injection while others benefit from a short course. Your plan is tailored following assessment.
Do I need a referral to be assessed for hip arthritis?
Not usually. If you already have imaging and a diagnosis you can often book directly. For more complex cases we may recommend consulting your GP first. We see patients across Sydney’s North-West and the Southern Highlands.
