PRP injections show promising but inconsistent results for hip bursitis, with roughly 80% of patients reporting some degree of improvement in the best studies. However, the evidence is mixed enough that major orthopedic organizations haven’t formally endorsed PRP for this condition. Whether it works well for you depends on what’s actually causing your hip pain, how long you’ve had it, and how you define “success.”
What the Research Actually Shows
Hip bursitis, more accurately called greater trochanteric pain syndrome (GTPS), has been studied in several clinical trials involving PRP. A 2023 systematic review analyzing multiple studies found that eight out of nine studies reported improvement and sustained symptom relief after PRP injections, while one showed no change at all. One study within that review reported a 79% improvement rate roughly three months after injection. A separate retrospective case series found that about 80% of patients reported improvement at around 12 weeks.
Those numbers sound encouraging, but the picture gets murkier when you look closer. A broader review of the available evidence described the role of PRP in treating greater trochanteric bursitis as “still controversial,” noting that four high-quality studies produced conflicting results. Two randomized controlled trials showed PRP outperformed corticosteroids at mid- to long-term follow-up. One short-term study found PRP didn’t help at all while steroid injections did. And one trial found no difference between PRP and a placebo injection for up to a year.
So while the majority of studies lean positive, the evidence isn’t as clean-cut as you might hope before spending several hundred dollars on a procedure.
How PRP Compares to Steroid Injections
Most people considering PRP have either already tried corticosteroid injections or are weighing the two options. The comparison is nuanced because the two treatments work on different timescales.
Corticosteroids typically provide faster relief. In studies of bursitis, steroid injections reduced pain scores more dramatically at one week and continued to outperform PRP at eight weeks in short-term assessments. For quick pain relief, steroids generally win the early rounds. But steroid effects tend to fade. Repeated steroid injections also carry risks of tissue weakening over time, which limits how often you can get them.
PRP’s potential advantage is durability. In one well-designed trial, patients who received PRP for greater trochanteric pain saw their hip scores improve from a baseline of 51 to 84 at three months, then hold steady at 87 at both six and twelve months. That sustained plateau suggests PRP may promote longer-lasting healing rather than just suppressing inflammation temporarily. Another study found 81% of patients with gluteus medius tendinopathy (a common component of hip bursitis) had moderate improvement to complete resolution of symptoms at an average follow-up of 15 months.
Not every study tells that story, though. One trial tracked patients for a full year and found that initial improvements at three months gradually declined by six and twelve months, with pain scores creeping back toward baseline. This suggests PRP doesn’t work equally well for everyone, and some patients may see benefits fade.
Why “Hip Bursitis” Matters Less Than You Think
One reason the research is inconsistent is that “hip bursitis” is often a simplification. What most people call hip bursitis, the pain on the outer side of your hip, is now understood as greater trochanteric pain syndrome. It can involve actual inflammation of the bursa, but it frequently includes damage or degeneration of the gluteal tendons that attach near the hip’s bony prominence. Many patients have both problems simultaneously.
This distinction matters for PRP because the treatment works by concentrating growth factors from your own blood and injecting them into damaged tissue. Those growth factors stimulate cell repair and new tissue formation. If your pain comes primarily from tendon damage, PRP has a more logical biological target and may work better. If your issue is purely inflammatory bursitis without structural damage, a corticosteroid might address the problem more directly.
Most studies that show strong PRP results involved patients with tendon involvement, not isolated bursal inflammation. Getting an accurate diagnosis, ideally with imaging, can help predict whether PRP is likely to help in your specific case.
What the Procedure Looks Like
A PRP injection for hip bursitis is typically done in a single visit. Blood is drawn from your arm, spun in a centrifuge to concentrate the platelets, and then injected into the trochanteric bursa and surrounding gluteal tendons using ultrasound guidance. The whole process takes about 30 to 60 minutes.
Most protocols call for a single injection, with the option to repeat at around six months if the first one doesn’t produce enough improvement. Some patients ultimately receive two or three injections total.
Expect an initial flare of pain in the first few days. This is the inflammatory phase, and it’s actually part of how PRP works: it triggers a controlled inflammatory response that jumpstarts healing. You’ll need to avoid strenuous activity for about two weeks. Most people return to normal activity around six weeks, with full recovery taking three to six months. Tendon injuries tend to sit at the longer end of that range.
Risks and Side Effects
PRP is a low-risk procedure. Because the injection uses your own blood, allergic reactions are far less likely than with corticosteroids or other medications. The most common side effects are soreness and bruising at the injection site, which resolve on their own.
Less common risks include bleeding, infection, tissue damage, and nerve injury. These are rare and generally associated with any injection procedure rather than PRP specifically. You should eat a meal and stay hydrated before the appointment, since the blood draw can cause lightheadedness otherwise.
Cost and Insurance Coverage
PRP injections typically cost between $750 and $850 per injection, according to Johns Hopkins Medicine. If you need two or three injections, that adds up quickly. Insurance coverage is inconsistent. Some insurers cover full or partial payment, but many still consider PRP experimental and won’t reimburse it. Contact your insurance company directly before scheduling to find out where you stand.
This cost factor is worth weighing against the evidence. If you’ve failed conservative treatments like physical therapy and steroid injections, PRP offers a reasonable next step with a roughly 80% chance of meaningful improvement based on the most favorable data. If you haven’t yet tried physical therapy or a single corticosteroid injection, those lower-cost, better-established options are worth pursuing first.
