Central compartment, lesser trochanter release offer similar results

For the treatment of internal snapping hip syndrome, both central compartment release and release at the lesser trochanter produced positive outcomes.
Researchers studied 20 patients diagnosed with internal snapping hip syndrome between 2008 and 2012 who treated with endoscopic release of the iliopsoas tendon. Six patients (Group 1) underwent tendon release at the lesser trochanter, and the remaining 14 (Group 2) underwent release from the central compartment. The researchers evaluated WOMAC scores preoperatively and at final follow-up. Minimum follow-up was 24 months.
On average, WOMAC scores improved in Group 1 from 50.1 preoperatively to 89.3 at final follow-up, whereas Group 2’s scores improved from 57.2 preoperatively to 89.7 at final follow-up. Associated injuries were commonly found and treated arthroscopically in both cohorts (four in Group 1 and 10 in Group 2), according to the researchers.
One patient in group 2 exhibited recurrence of snapping that required surgical fixation. No complications were observed.
