Early Results of Labral Repair (SS-17)

Abstract

The purpose of this study is to report early results of function and patient satisfaction in labral repair patients. Patients experienced improvement in function at least 6 months postoperatively. Early results demonstrate that arthroscopic labral repair for the treatment of labral tears lead to improved level of function and high patient satisfaction. This reveals the potential of labral repair in pain management and joint preservation. This may be important when developing a standard of surgical labral tear treatment. Previous arthroscopic intervention has included labral debridement, excision and repair. Studies suggest that debridement and excision, while alleviating immediate pain, compromise labral structure and function, leading to narrowed joint space and early arthrosis. It is believed that arthroscopic labral repair restores proper labral structure therefore preserving its physiological function. Little has been reported on labral repair postoperatively. The purpose of this study is to report early results of function and patient satisfaction in labral repair patients. 52 patients underwent arthroscopic labral repair (26 male, 26 female). Patients completed subjective questionnaires preoperatively and at least 6 months post-operatively. Data was collected from the Hip Outcome Score (HOS), the Non-Arthritic Hip Score (NAH), and the Modified Harris Hip Score (MHH). Patient Satisfaction was also collected (1=unsatisfied, 10=very satisfied). The average postoperative follow-up was 9 months (range 6 to 15). Average age at follow-up was 34 (range 13 to 50). Postoperatively, the HOS (ADL and SPORT), NAH, and MHH all experienced significant improvement (p<0.05). HOS (SPORT) had the greatest improvement of 31 points increasing to 74. HOS (ADL) increased from 69 to 88. NAH score improved 20 points to 85. MHH score improved 21 points to 82. Patient Satisfaction was 8.5 (range 1 to 10). 11 of the 52 patients were at least one year post-op. The average age within this subgroup was 34 (range 17 to 45). There was a significant improvement in all scores (p<0.05) compared to preoperative values and patient satisfaction was 8.8. At one year, HOS (SPORT) increased from 34 to 80 points, HOS (ADL) improved 22 points to 86, NAH improved 31 points to 89 and MHH score increased from 58 to 83 points. Patients experienced improvement in function at least 6 months postoperatively. Patients continue to experience improvement at one year or more. Early results demonstrate that arthroscopic labral repair for the treatment of labral tears lead to improved level of function and high patient satisfaction. This reveals the potential of labral repair in pain management and joint preservation. This may be important when developing a standard of surgical labral tear treatment.
