Abstract
PURPOSE: To investigate the clinical outcome, level of patient satisfaction, re-injury and re-operation rates of patients 7-10 years after augmented hip abductor tendon repair. METHODS: Between October 2012 and May 2015, 146 patients were referred to the senior author with symptomatic hip abductor tendon tears, of which 110 (101 female, 92%) were included in the current study and underwent hip abductor tendon repair augmented with LARS. Patients had a mean age of 63.2 years (range 43-82), body mass index of 27.8 (range 20.0-40.2) and duration of symptoms of 3.6 years (range 6 months-18 years). Patient-reported outcome measures (PROMs) were evaluated pre-operatively and at 3, 6, 12 and 24 months, as well as 7-10 years post-operatively, including the Oxford Hip Score (OHS), 12-item Short Form Health Survey (SF-12), a Visual Analogue Pain Scale (VAS) evaluating the frequency (VAS-F) and severity (VAS-S) of hip pain, and patient satisfaction. Adverse events, surgical failures, revisions and subsequent treatments on the ipsilateral hip were reported. RESULTS: A significant improvement (p < 0.05) was observed for all PROMs and, while a mean deterioration was observed for all PROMs from 24 months to final review (7-10 years), these were not significant (n.s.). In the 90 patients retained and assessed at final review, 93% were satisfied with their hip pain relief and 89% with their ability to participate in recreational activities. Overall, 9 (of 110, 8.2%) surgical failures were observed over the 7-10-year follow-up period. CONCLUSIONS: Good clinical scores, a high level of patient satisfaction and an acceptable re-injury rate were observed at 7-10 years after augmented hip abductor tendon repair, demonstrating satisfactory repair longevity. LEVEL OF EVIDENCE: IV.
