PRP for Hip Arthritis: What to Know Before You Decide
Updated: 17 hours ago
The Hip Is Not Just a Deep Knee
Patients often assume PRP works the same in every joint — if it helps knee arthritis, it should help hip arthritis equally. The reality is more nuanced. The hip is deeper, harder to inject accurately, studied less than the knee, and surrounded by structures (bursae, tendons, the labrum) that frequently generate the pain instead of — or alongside — the joint itself.
PRP has a legitimate role in hip arthritis. But the evaluation matters more here than almost anywhere else, because treating the wrong structure with the right biologic still fails.
What the Evidence Shows
The hip PRP literature is thinner than the knee's but directionally positive:
Randomized trials and case series report pain and function improvements in mild-to-moderate hip osteoarthritis following PRP, with benefits typically measured at 6–12 months
Head-to-head data vs. hyaluronic acid favors PRP in several studies, mirroring the knee pattern
The evidence base is smaller and more heterogeneous than knee OA — fewer large RCTs, more variability in preparation and protocol
As with the knee, no credible evidence of cartilage regrowth — the benefit is symptom modification through inflammatory modulation
Our read: PRP is a reasonable option for hip OA, with the confidence level set one notch below the knee — which has the deepest trial base in orthobiologics.
Why the Diagnosis Comes First
This is the part that separates a good hip PRP outcome from a wasted injection. Hip-region pain has several common generators, and they need different treatments:
Hip osteoarthritis — deep groin ache, worse with weight-bearing, limited internal rotation; the PRP target
Trochanteric bursitis / gluteal tendinopathy — outer hip pain, tender to lie on; often the actual diagnosis when patients say "hip arthritis" (we've written about gluteal tendinopathy and PRP specifically)
Hip labral tear / FAI — groin pain with clicking or catching in younger active patients
Referred pain — from the lumbar spine or SI joint
Our workup — exam, X-ray, and diagnostic ultrasound — sorts this out before any needle is discussed. Injecting PRP into an arthritic-looking hip that's actually gluteal tendinopathy is the most common reason hip "PRP failures" happen.
Ultrasound Guidance Is Non-Negotiable
The hip joint sits several inches deep, surrounded by the femoral nerve, artery, and vein anteriorly. A blind hip injection is a guess; studies show landmark-guided hip injections miss the joint a meaningful percentage of the time. Every hip injection we do is ultrasound-guided — direct visualization of the needle entering the joint space. For the hip, this isn't a premium feature; it's the minimum standard.
Who Benefits Most
Mild-to-moderate hip OA on X-ray with concordant groin pain
Patients wanting to delay hip replacement — PRP as a bridge strategy, often buying 1–2 years
Patients who can't take NSAIDs or want to avoid repeated cortisone
Active adults whose arthritis is pain-dominant rather than mechanical (stiffness and deformity respond less)
Less suitable: bone-on-bone disease with significant deformity or leg-length change, rapidly progressive collapse (possible AVN — different workup, urgent), or pain that's actually trochanteric/gluteal (different injection target entirely).
PRP vs. MFAT for the Hip
As with the knee: PRP first — lower cost, minimal downtime, reasonable evidence. **MFAT cell therapy** — which we also offer for the hip — is the bigger intervention: mini-liposuction procedure, higher cost, evidence for longer-lasting relief. Patients with more advanced disease, or who want the longest-acting option before considering replacement, often choose MFAT. We'll lay out both honestly and let the arthritis grade and your goals decide.
What to Expect
Blood draw, processing, ultrasound-guided injection deep into the hip joint — the procedure takes under an hour. Soreness for a few days is normal. Unlike the knee, you'll feel this one more (it's a deeper stick); most patients are back to normal activity within days. Improvement builds over 6–12 weeks; we reassess at 3 months.
The Bottom Line
PRP for hip arthritis: real but thinner evidence than the knee, excellent outcomes when the diagnosis is right, wasted money when the pain is actually gluteal tendinopathy mislabeled as arthritis. The evaluation is the treatment.
