Purpose

The purpose of this study was to evaluate the clinical outcomes of a cohort of patients who underwent labral repair by use of a previously published labral base repair suture technique for the treatment of acetabular labral tears and pincer-type femoroacetabular impingement (FAI).

Methods

Patients who received hip arthroscopy for symptomatic intra-articular hip disorders and underwent the previously described labral base repair technique were included in the study group. Patients who had Tönnis arthritis grade 2 or greater, had Legg-Calves-Perthes disease, or underwent simple looped stitch repair were excluded. The patient-reported outcome scores included the modified Harris Hip Score, the Non-Arthritic Hip Score, the Hip Outcome Score–Activities of Daily Living, and the Hip Outcome Score–Sport-Specific Subscale obtained preoperatively and at 2 years' and 3 years' follow-up. Any complications, revision surgeries, and conversions to total hip arthroplasty were noted.

Results

Of the patients, 54 (82%) were available for follow-up. The mean length of follow-up for this cohort was 2.4 years (range, 1.7 to 4.1 years). At final follow-up, there was significant improvement in all 4 patient-reported outcome scores (modified Harris Hip Score, 63.7 to 89.9; Non-Arthritic Hip Score, 60.9 to 87.9; Hip Outcome Score–Activities of Daily Living, 66.9 to 91.0; and Hip Outcome Score–Sport-Specific Subscale, 46.5 to 79.2) (P < .0001). A good or excellent result was achieved in 46 patients (85.2%). There was significant improvement in pain as measured by the change in visual analog scale score from 6.5 to 2.3 (P < .0001), and the patient satisfaction rating was 8.56 ± 2.01. There were no perioperative complications. Revision surgery was required in 3 patients (5.6%), and 2 patients (3.7%) required conversion to total hip arthroplasty.

Conclusions

The clinical results of this labral base repair technique showed favorable clinical improvements based on 4 patient-reported outcome questionnaires, visual analog scale, and patient satisfaction. More clinical, biomechanical, and histologic studies are needed to determine the optimal repair technique.

Methods

At our institution, data are prospectively collected on all patients undergoing hip preservation surgery. The PRO scores include the modified Harris Hip Score (mHHS), the Non-Arthritic Hip Score (NAHS),14 the Hip Outcome Score–Activities of Daily Living (HOS-ADL), and the Hip Outcome Score–Sport-Specific Subscale (HOS-SSS)15 obtained preoperatively and at 2 years' and 3 years' follow-up. All 4 questionnaires are used because it has been reported that there is no conclusive evidence for the use

Results

During the study period, 66 patients met the inclusion criteria. Of these patients, 54 (82%) were available for follow-up. The mean age was 28.8 ± 12.8 years (range, 14 to 57 years). One patient had a prior hip arthroscopy at an outside institution and underwent revision because of continued hip pain from unaddressed FAI, whereas all others underwent primary hip arthroscopy. The mean length of follow-up for this cohort was 2.4 ± 0.58 years (range, 1.7 to 4.1 years). Patient demographic data are

Discussion

Arthroscopic labral repair by the described LBR technique has been shown to be a successful technique for labral repair based on the PROs reported in this study. This technique generated a response from advocates of the looped stitch technique when initially published.12 Although the benefits of labral repair continue to be shown,7, 8, 9, 10 on the basis of current clinical outcomes research, the specific technique most optimal for repair remains to be determined. The theoretical benefit of LBR

Conclusions

The clinical results of the described LBR technique showed favorable clinical improvements based on 4 PRO questionnaires, the VAS, and patient satisfaction. More clinical, biomechanical, and histologic studies are needed to determine the optimal repair technique.
