Purpose
The purpose of this study was to assess the surgical outcomes of endoscopically repaired
full-thickness abductor tendon tears using validated outcome measures.
Methods
After institutional review board approval was obtained, clinical outcome data were
retrospectively collected from patients who underwent endoscopic gluteus medius and/or
minimus repair by a single surgeon between August 2009 and September 2011. With a
minimum follow-up of 1 year, patients were evaluated using the modified Harris Hip
Score and the validated Hip Outcome Score (HOS). The HOS questionnaire included 2
subsections: HOS–Activities of Daily Living and HOS-Sports. Physical examination data
were gathered during routine clinic visits, 1 year postoperatively. Statistical analysis
was descriptive. The change in strength testing postoperatively was assessed with
the Wilcoxon signed rank test, with significance set at P ≤ .05.
Results
Twelve patients were identified, 1 of whom was excluded; 10 of 11 patients (91%) completed
the study requirements. The mean patient age was 65.9 years (range, 60 to 74 years),
70% were women, and the mean follow-up period was 23 months (range, 13 to 38 months).
The mean postoperative scores were 84.7 (SD, 14.5) for the modified Harris Hip Score
and 89.1 (SD, 11.3) for the HOS–Activities of Daily Living, with 90% patient satisfaction.
All patients had clinically and statistically improved abductor tendon strength (P = .004). Patients with good to excellent outcomes were younger (P < .001). There were no complications identified.
Conclusions
In our small series, endoscopic abductor tendon repair was an effective surgical intervention
after failed conservative management at short-term follow-up. Patients had reliably
good to excellent outcomes with improved strength during hip abduction, were at low
risk of complications, and were satisfied with the outcome. In addition, younger patients
achieved better outcomes.
Level of Evidence
Level IV, therapeutic case series.
