Table 3. Operative treatments of GTPS related to GMed.
| Report | Cases | Treatment | Outcomes |
| Brooker AF76) | Patients with refractory TB (n=5) | Decompression by fenestration of bursa | All cases achieved pain relief and average HHS score was improved |
| Kagan A77) | Patients with unresponsive TB (n=7) | GMed repair/fasciotomy | All cases achieved pain relief and one case had weakness of the GMed |
| Govaert LH et al.78) | Patients with chronic TB (n=12) | Trochanteric osteotomy | Outcomes were very good in 6/12 (50%) and good in 5/12 (41.7%) |
| *5 cases refractory to bursectomy | Pain and physical function (Merle d’Aubigné and Postel Method) were significantly improved | ||
| Baker CL et al.79) | Patients with refractory TB (n=42) | Endoscopic bursectomy | 44/45 (97.8%) had improved symptoms/postoperative average JOA score |
| Davies H et al.80) | Patients with GTPS unresponsive to conservative treatment (n=16) | GMed/GMin repair and bursectomy | 11/16 had significant reduction of hip symptoms; 5/16 had relapse |
| Voos JE et al.81) | Patients with GMed tear (n=10) | Endoscopic gluteus medius repair | All cases had complete resolution of pain; MMT of hip abd. was improved |
| Walsh MJ et al.82) | Patients with GTPS unresponsive to conservative treatments (n=72) | Gluteal tendon repairs | More than 90% of cases were pain-free or had minimal pain; repair surgery significantly improved hip score |
| Davies H et al.83) | Patients with unresponsive TB with tear of hip abd. by MRI (n=23) | Open gluteal tendon repair | 23/23 had significant improvement in VAS, OHS, and SF-36 PCS |
| Chandrasekaran S et al.84) | Patients who underwent endoscopic GMed repair (n=24) | Endoscopic GMed repair | Age-matched non-surgery group had significantly greater strength than the surgery group; GMed strength is a possible risk factor for surgical intervention |
TB: trochanteric bursitis; GTPS: greater trochanteric pain syndrome; Cs: corticosteroid; abd.: abductor; ESWT: extracorporeal shockwave therapy; PRP: platelet-rich plasma; GMed: gluteus medius; GMin: gluteus minimus; LDD: lumber degenerative disease; JOA: Japanese Orthopaedic Association; VAS: visual analogue scale; HHS: Harris Hip Score; OHS: Oxford Hip Score; SF-36: MOS Short-Form 36-Item Health Survey.
