A comparison of outcomes after endoscopic repair of partial versus full-thickness tears of the Gluteus Medius tendon.

Abstract Purpose The purpose of this study was to evaluate and compare the functional outcomes after endoscopic repair of partial or full-thickness gluteus medius tears at a minimum 2 years’ follow-up. Methods Patients with isolated tear of the gluteus medius tendon repaired endoscopically between 2012 and 2017 were evaluated at a minimum 2 years follow-up. Patients with large, retracted and:or irreducible tears, advanced atrophy or fatty degeneration or with concomitant other hip pathology were excluded. Functional outcomes were assessed using the modified Harris Hip score (mHHS), Non arthritic Hip Score (NAHS) and visual analogue scale (VAS) for pain preoperatively and at the last follow-up Results Forty-six patients, 3 men and 43 women with mean age of 63 ± 9 [43-82] years were included. 33 patients (72%) had partial thickness tear and 13 (28%) had full thickness tear. Pain was reduced significantly from a median of 8 (Q1-Q3: 6-8) at the preoperative visit to a median of 2 (Q1-Q3:15) at the most recent follow-up (p Conclusion Endoscopic repair of gluteus medius tendon tears yields excellent functional outcomes at a minimum follow-up of 2 years. A lower functional improvements for full thickness tear was observed; this difference was statistically significant for one of the two scores evaluated Level of evidence III, Retrospective comparative cohort.
