Abstract

Background: The transtendinous technique has been used to treat partial-thickness gluteus medius tears in the setting of concomitant arthroscopy for labral tears. The tendon compression bridge technique for gluteus medius repair has been developed as an alternative method, providing several advantages; however, comparative studies between the 2 techniques are lacking in the literature. Purpose: (1) To evaluate the short-term patient-reported outcomes (PROs) of the tendon compression bridge technique and (2) to compare these findings with short-term PROs of the transtendinous technique. Study Design: Cohort study; Level of evidence, 3. Methods: Data were prospectively collected on patients who were followed for a minimum of 2 years after an endoscopic tendon compression bridge procedure for gluteus medius repair in the setting of concomitant hip arthroscopy for labral tears. The following PROs were collected preoperatively and postoperatively: modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score–Sports Specific Subscale, visual analog scale score for pain, and the International Hip Outcome Tool. Clinical outcomes were assessed using the Patient Acceptable Symptom State, minimal clinically important difference, and maximum outcome improvement satisfaction threshold. Patients were propensity matched 1:1 to a cohort that underwent gluteus medius repair using the endoscopic transtendinous technique with concomitant hip arthroscopy. Results: A total of 48 hips (48 patients) that met inclusion criteria (age, 53.3 ± 9.8 years; 92% female; body mass index, 26.7 ± 4.6), with a mean follow-up of 38.5 ± 15.7 months, were matched to 48 hips (46 patients) that underwent gluteus medius repair using the transtendinous technique. Both groups demonstrated significant improvement from preoperative scores to latest follow-up (P <.05). Mean magnitude of improvement and latest follow-up scores were not significantly different between the tendon compression bridge group and the transtendinous group, and the groups demonstrated similar favorable rates of achieving Minimal Clinically Important Difference (79% vs 79%, respectively), Patient Acceptable Symptom State (73% vs 73%, respectively), and Maximum Outcome Improvement Satisfaction threshold (65% vs 58%, respectively) for modified Harris Hip Score (P >.05). Patient satisfaction between groups was similar (8.1 ± 2.2 vs 7.7 ± 2.7, respectively) (P =.475). Conclusion: At minimum 2-year follow-up, the endoscopic tendon compression bridge technique for partial-thickness gluteus medius tears, when performed with concomitant hip arthroscopy, was associated with significant improvement in functional outcomes. These postoperative results were comparable with those of a matched cohort that underwent the endoscopic transtendinous technique for partial-thickness gluteus medius tears, suggesting that the tendon compression bridge technique for gluteus medius repair is an effective treatment option for partial-thickness gluteus medius tears.
