First author | References | Technique | Number of hips | Follow-up (months) | Results |
|---|---|---|---|---|---|
Taylor | [7] | Open release (medial approach) | 17 | 17 | 31 % residual pain, 38 % recurrent snapping, 12.5 % had persistent weakness with hip flexion |
Jacobson | [8] | Open Z plasty | 20 | 25 | 19 reductions of snapping frequency, 14 no snapping, 2 required reoperation, 3 subjective weakness |
Dobbs | [9] | Open Z plasty (iliofemoral incision) | 11 | 48 | 11 had complete pain relief, no patient had detectable loss of hip flexion strength, 1 patient had a recurrence of the snapping, and 2 patients had a transient decrease in sensation over the anterolateral thigh due to injury of the lateral femoral cutaneous nerve |
Gruen | [10] | Open Z plasty (ilioinguinal incision) | 11 | 36 | 58 % complete resolution of their hip pain, 17 % had recurrence, 25 % improved, 5 had postoperative subjective weakness. No complications related to the wound or surgical approach |
Hoskins | [11] | Open tendon lengthening (iliofemoral incision) | 92 | 65 | 12 % recurrence of snapping within 3 months and another 10 % after 3 months, 12 % had surgical incision related complications |
Byrd | [4] | Endoscopic release at lesser trochanter | 9 | 20 | All patients pain free, no recurrence |
Ilizaliturri | [12] | Endoscopic release at lesser trochanter (10) and endoscopic transcapsular (9) (randomized) | 19 | 20 | Improvements in WOMAC scores were statistically significant in both groups, and no difference was found in postoperative WOMAC results between groups. No complications were seen |
Anderson | [13] | Endoscopic release at lesser trochanter (athletes) | 12 | 9 | Preoperative hip scores averaged 41 and 44 points for the competitive and recreational athletes, respectively, at 12 months, 96 and 97 points, and none had recurrence of their snapping or pain |
Flanum | [14] | Endoscopic release at the lesser trochanter | 6 | 12 | 38 points average Harris hip scores increase, no recurrence |
Wettstein | [15] | Endoscopic release (preserving iliacus muscle) transcapsular | 9 | 3 | No complications, hip flexion strength was restored to normal within 3 months |
Ilizaliturri | [16] | Endoscopic release at the lesser trochanter | 7 | 21 | All the patients were relieved of their painful snapping symptoms, average WOMAC score improved from 82.5 to 91 points. The only complication seen was loss of flexion strength in all patients |
Domb | [6] | Endoscopic tenotomy and either labral debridement or repair | 25 | 21 | Mean preoperative HHS, ADL HOS, and Sport HOS scores were 61.64, 73.94, and 51.63, respectively, the mean post-operative scores were 86.06, 88.21, and 72.01, respectively |
