What Is Greater Trochanteric Pain Syndrome?

Greater trochanteric pain syndrome, usually called GTPS, is a condition that causes pain on the outer side of the hip, and it affects roughly one in six women and one in twelve men. For decades, doctors labeled it “trochanteric bursitis” and treated it as an inflamed fluid sac. That framing has largely been replaced: the pain usually comes from wear and damage in the gluteal tendons that attach to the bony prominence on the side of the femur, not from the bursa itself. Understanding that shift matters because it changes which treatments actually help.

What Is Actually Happening in the Hip

The greater trochanter is the knob of bone you can feel on the outer edge of your hip. Two muscles essential for hip stability, the gluteus medius and gluteus minimus, anchor to it via tendons. For years, the standard explanation was that a small fluid-filled sac (bursa) sitting over the trochanter became inflamed, hence “trochanteric bursitis.” Newer research has shifted that understanding. An ultrasound study of 877 patients with lateral hip pain found that isolated bursitis was actually rare; instead, the dominant finding was tendon pathology in the gluteal muscles.¹ The umbrella term “greater trochanteric pain syndrome” was adopted specifically because the old name pointed clinicians toward the wrong tissue.²

The tendons of the gluteus medius and minimus can develop small areas of degeneration, partial tears, or full-thickness tears. A cadaveric study found that blood supply to the gluteus medius tendon declines significantly with age, which may help explain why GTPS becomes more common as people get older. The relationship between age and reduced blood vessel density in the tendon was statistically significant across multiple zones of the tendon.³ When the tendon loses its blood supply, it heals more slowly after micro-injuries and becomes prone to the kind of chronic degeneration clinicians call tendinopathy.

Compressive load on the tendons is also a major contributor. The iliotibial band runs over the greater trochanter, and when it’s tight or when the hip is repeatedly held in an adducted position (legs crossed, standing with one hip dropped), it presses the gluteal tendons against the bone.⁴ This mechanical compression, repeated over months and years, is thought to be one of the main drivers of tendon breakdown.

Who Gets GTPS

Women are affected far more than men. A large community-based study found unilateral GTPS in about 15% of women versus roughly 7% of men, and bilateral GTPS in about 9% of women compared to 2% of men. The odds of having GTPS were more than three times higher for women. Interestingly, age and race were not significantly associated with the condition in that study.⁵ The sex difference is often attributed to women having wider pelvises on average, which increases the angle at which the gluteal tendons pull on the greater trochanter and increases compression from the iliotibial band. Hormonal changes around menopause may also play a role, though that link is less firmly established.

People with lower back problems are at particularly high risk. A study of patients referred to orthopedic spine specialists found GTPS in about one in five of them, and significantly more women than men in that group had the condition. Of those diagnosed, nearly two-thirds had already been evaluated by a spine surgeon or orthopedist without anyone identifying the lateral hip as the pain source. One patient had actually undergone two lumbar decompressions without improvement before GTPS was recognized.⁶ That overlap with back pain is one of the biggest diagnostic traps, and it’s worth knowing about if you’ve had persistent lateral hip or thigh pain that doesn’t seem to respond to spinal treatments.

What It Feels Like

The hallmark symptom is pain over the bony point on the outside of the hip. It usually worsens with weight-bearing activities, walking, climbing stairs, or lying on the affected side at night. That nighttime component can be especially disruptive. One clinical case described a patient who couldn’t lie on her affected side and had difficulty walking more than five minutes.⁷ Pain can also radiate down the outer thigh, sometimes as far as the knee, which is part of why it’s confused with sciatica or lumbar radiculopathy.

The functional impact is larger than many clinicians initially assume. A study comparing people with GTPS, people awaiting hip replacement for severe osteoarthritis, and pain-free controls found no meaningful difference in hip scores between the GTPS and osteoarthritis groups. Both had significantly lower quality of life than the controls. People with GTPS were actually the least likely to be working full-time.⁸ That finding pushes back against the notion that GTPS is a minor nuisance. For many people, it’s seriously debilitating.

How Doctors Diagnose It

Diagnosis is primarily clinical, meaning it’s based on a physical exam rather than imaging. A systematic review with meta-analysis found that a combination of two tests can either confirm or largely rule out GTPS in someone with lateral hip pain. If pressing on the gluteal tendon area (palpation) doesn’t hurt and resisted hip abduction (pushing the leg outward against resistance) is painless, the probability of GTPS drops from about 59% to 14%. On the other hand, if both tests are positive, the probability jumps from 59% to 96%.⁹

Another well-studied test involves standing on the affected leg for 30 seconds. If this reproduces the patient’s usual pain within that time, the test is considered positive for gluteal tendinopathy. One study reported very high sensitivity and specificity for this single-leg stance test.¹⁰

When Imaging Helps and When It Doesn’t

MRI can detect gluteal tendon tears with reasonable accuracy. One study found about 91% accuracy for identifying tears, with specific signal patterns on the images correlating strongly with confirmed tears.¹¹ However, a systematic review found that MRI sensitivity varied wildly across studies, ranging from 33% to 100%, with false-positive findings being common.¹² That means a normal MRI doesn’t rule out GTPS, and an abnormal MRI doesn’t guarantee GTPS is the source of pain.

Ultrasound is another option, and it’s less expensive and faster. One comparison study found that ultrasound correctly identified pathological gluteus medius tendons in most cases, but it also incorrectly flagged five out of six normal tendons as abnormal. Both MRI and ultrasound struggled to distinguish between tendinosis (degeneration without tearing) and partial-thickness tears.¹³ The practical takeaway: imaging is helpful when a clinician needs to assess tear severity before deciding on surgery, but for routine GTPS management, clinical tests are often enough.

Conditions That Mimic GTPS

The list of things that can cause lateral hip pain is long enough to create real confusion. Hip osteoarthritis is one of the most important to differentiate because the two conditions frequently coexist. Although osteoarthritis pain typically shows up in the groin or front of the thigh, a retrospective analysis found that about 27% of patients with an intra-articular hip problem experienced pain over the lateral thigh. The FABER test (flexion, abduction, external rotation of the hip) can help distinguish the two when pain is reproduced laterally. Lumbar spine problems are another common mimic. The referred pain pattern from GTPS overlaps with the L2 through L4 nerve root distributions, and lumbar stenosis can even produce hip abductor weakness that looks like the Trendelenburg gait seen in GTPS. The prevalence of GTPS among patients referred for lower back pain evaluation was found to be as high as 51% in one analysis. Meralgia paresthetica, a nerve condition causing numbness and burning on the outer thigh, also enters the differential. Point tenderness over the lateral inguinal ligament rather than the greater trochanter, and the presence of Tinel’s sign near the front of the pelvis, help distinguish it.¹⁴

Exercise and Load Management

Exercise programs are currently the best-supported first-line treatment. A systematic review with meta-analysis found that exercise-based interventions, particularly progressive loading programs combined with education, outperformed minimal interventions like sham exercise or a wait-and-see approach for both short-term and long-term symptom severity. Exercise also had a higher treatment success rate than corticosteroid injections at both short and long follow-ups, even though both approaches reduced pain to a similar degree.¹⁵ A pilot study comparing isometric exercises (holding a position without movement) to isotonic exercises (moving through a range) found both approaches effective, suggesting there isn’t one clearly superior loading strategy at this point.¹⁶

Education about load management is considered just as important as the exercises themselves. A classification-based treatment framework recommends reducing compression through the lateral hip by avoiding prolonged single-leg standing, not crossing your legs while sitting or standing, and sleeping on your back with a pillow under your knees or on your side with a pillow between your legs. During daily activities, sitting down to put on pants rather than balancing on one leg reduces the demand on the gluteal tendons.¹⁷ These modifications sound minor, but for a tendon that’s being compressed hundreds of times per day, cumulative offloading can matter.

Corticosteroid Injections

Steroid injections into the trochanteric area remain one of the most commonly prescribed treatments, but their track record is mixed. A meta-analysis of randomized controlled trials found that corticosteroid injections did not significantly reduce pain compared to usual care or “wait and see” at the six-month mark. A modest long-term benefit did emerge at 12 months, with corticosteroid injection also showing a small but statistically significant improvement in function at that point.¹⁸ For many patients, the injection provides a few weeks of relief before symptoms return. This pattern makes more sense if the underlying problem is tendon degeneration rather than bursitis: steroids can reduce inflammation in a bursa, but they don’t heal a worn-out tendon, and some evidence suggests repeated steroid injections may actually weaken tendons over time.

Shockwave Therapy

Extracorporeal shockwave therapy, which uses acoustic pressure waves directed at the painful area, has generated interest as a non-invasive option. A multicenter randomized controlled trial of focused shockwave therapy showed a significant drop in pain scores, from an average of 6.3 at baseline to 2.0 in the treatment group compared to 4.7 in the control group at two months. Most secondary outcomes were also significantly better in the shockwave group.¹⁹ However, the picture is more complicated than one trial suggests. A separate double-blinded trial using radial shockwave therapy found no difference between a “recommended dose” of three full sessions and a “minimal dose” control, raising questions about whether the type of shockwave matters or whether other factors in the treatment environment explain the results.²⁰ The distinction between focused and radial shockwave may be relevant here; the positive trial used focused shockwave, while the neutral trial used radial. This area of research is still evolving.

Platelet-Rich Plasma Injections

PRP injections, in which a concentrated preparation of the patient’s own platelets is injected into the damaged tendon, have shown promise in head-to-head comparisons against corticosteroid injections. A randomized, double-blind trial of 80 patients with chronic gluteal tendinopathy found no difference between PRP and corticosteroid at two or six weeks, but at 12 weeks, the PRP group had significantly better scores. About 82% of PRP recipients achieved a clinically meaningful improvement compared to roughly 57% in the corticosteroid group.²¹ A follow-up from the same research group indicated that PRP benefits persisted for up to two years, while corticosteroid benefits faded after about six weeks and did not last beyond 24 weeks.²²

The catch is that PRP is often not covered by insurance, it can cost several hundred dollars per injection, and formulations vary. Different PRP preparations contain different concentrations of platelets and white blood cells, and the ideal formulation for tendon healing is still debated. If you’re considering PRP, ask the provider what type of preparation they use and whether the evidence for that specific formulation exists in tendon studies.

When Surgery Becomes an Option

Surgery is generally reserved for people who haven’t improved with at least six months of conservative management, particularly those with confirmed full-thickness gluteal tendon tears. Both open and endoscopic repair techniques have been studied. A review of surgical repair methods found that outcomes generally improved regardless of how the tear happened, with newer techniques showing particular promise.²³

A prospective study of endoscopic repair for full-thickness tears reported significant improvements in pain scores, hip abduction strength, and patient-reported outcome measures at a minimum of two years. All 15 hips in the study showed resolution of a Trendelenburg sign, meaning the patients could stand on the operated leg without their pelvis dropping on the opposite side. The majority of patients exceeded the threshold for a clinically meaningful difference on multiple outcome scales.²⁴ Open repair has also shown good results: one prospective study of refractory cases found steady complete pain remission in seven of eight patients after tendon reattachment, with follow-up MRIs confirming good reinsertion of the sutured tendon.²⁵

Recovery After Gluteal Tendon Repair

Rehabilitation after surgery follows a cautious loading progression. A systematic review of postoperative protocols found that most surgeons prescribe partial weight bearing with crutches for six to 12 weeks, with active hip abduction restricted for at least six weeks. Many studies used an abduction brace for six to eight weeks. Failure rates were low regardless of bracing: about 3.8% with a brace versus 4.4% without.²⁶

A laboratory study examining the forces on the gluteus medius tendon during different weight-bearing conditions helps explain why the recovery timeline is so long. At full weight bearing, the gluteus medius tendon experiences substantial force. Partial weight bearing reduced that load by about 68%, and full non-weight bearing reduced it by roughly 88%. The researchers recommended partial weight bearing when suture stability was sufficient, to avoid the muscle atrophy that comes with complete unloading, while full non-weight bearing was advised when tendon or bone integrity was compromised.²⁷ Returning to full activity typically takes four to six months.

Habits That Protect Your Lateral Hip

Whether you’re managing active GTPS or trying to prevent it, the same biomechanical principles apply. The gluteal tendons are compressed when the hip is in an adducted position, which means any posture or habit that pushes the knee across the midline of the body loads that area. Crossing your legs, standing with your weight shifted entirely to one side, and sleeping on your side without a pillow between your knees all increase compression. Runners who overstride or have a narrow step width may also place more stress on the lateral hip.

Strengthening the hip abductors is protective in the same way that strengthening the rotator cuff muscles can protect the shoulder. But the loading has to be appropriate. Going straight to heavy resistance band walks or single-leg exercises when the tendon is already irritated can make things worse. Starting with isometric holds, where you push your knee into a wall at a comfortable intensity and hold without movement, lets the tendon adapt without the compression that comes from full range-of-motion exercises in positions of hip adduction. Progressing slowly, adding resistance and range as pain allows, reflects how tendons actually heal: gradually, over weeks and months, in response to the right amount of mechanical stimulus.
