BackgroundGreater trochanteric pain syndrome (GTPS) is a common cause of lateral hip pain that affects patients' quality of life and functioning. The condition is often associated with tightness of the iliotibial band (ITB) and tendinopathy of the gluteus medius (GMed) tendon, which are subjected to excessive stress and inflammation. A traditional treatment for GTPS is conservative medical management (CMM), which includes but is not limited to physiotherapy, oral anti-inflammatory medication, and/or local steroid injections. Surgery is performed when these treatments fail. The failure of these techniques indicates that some treatments classified as CMM may not be feasible for some patients.ObjectivesThis study aimed to evaluate the efficacy and safety of combined GMed and ITB injections for a cohort of CMM-refractory GTPS patients.Study DesignA retrospective chart review.SettingSingle-center, academic hospital.MethodsBetween 01/01/2022 and 12/31/2022, a retrospective analysis of 68 hips that underwent combination GMed-ITB percutaneous ultrasound tenotomy (PUT) was performed. The primary outcome measure was a numeric rating scale (NRS) for hip pain, and the secondary outcome measures were VISA-G (Victorian Institute of Sports Assessment-Gluteal Tendinopathy) scores, sitting-to-standing and walking tolerance, and side-lying tolerance.ResultsThe patients' NRS scores decreased, and the VISA-G scores and all functional measures increased one year after the procedure, indicating significant improvement in pain and functioning (P < 0.001). Treatment success, defined as 50% reduction in pain and side-lying tolerance, was achieved by 83% of the patients. No major complications were reported.LimitationsThe lack of a comparable cohort reduces the data's interpretative significance. Having a control arm would have enabled a statistical comparison between treated and untreated patients to provide a valid assessment of the procedure's benefit.ConclusionsThis study demonstrated the feasibility and efficacy of combined GMed-ITB PUT as a novel treatment for GTPS in patients who failed CMM. The results showed significant and durable improvement in pain, function, and quality of life at the one-year follow-up. Our study suggests that both ITB and GMed tendons are involved in the pathogenesis of GTPS. The present study compared favorably with previous studies that reported outcomes of either ITB PUT or GMed PUT alone, implying that combining the approaches may offer superior benefits. Furthermore, the study had several strengths, such as the use of a validated outcome measure (VISA-G), the elimination of bias by independent practitioners, and the inclusion of a difficult population with severe pain.
