Aims

This study uses prospective registry data to compare early patient outcomes following arthroscopic repair or debridement of the acetabular labrum.

Background. The acetabular labrum provides sealing function and a degree of hip joint stability. Previous early(16 month) and mid-term(mean 3.5 years) follow-up of this cohort reported better patient related outcome measures in the refixation group. Methods. We reported patients who underwent labral debridement/focal labral excision during a period before the development of labral repair techniques. Patients with labral tears thought to be repairable with our current arthroscopic technique were compared with patients who underwent labral refixation. In 46 hips, the labrum was focally excised/debrided (group 1); in 54 hips, the labrum was refixed (group 2). Outcomes were measured with modified-Harris-Hip-Score (mHHS), Short Form-12 (SF-12), and a visual-analog-scale(VAS) for pain preoperatively and postoperatively. Results. Mean age was 33 years in group 1 and 28 years in group 2 with mean follow-up of 7 years (range, 2–13.6 years). At mean follow-up, subjective outcomes were significantly improved (P<.01) for both groups compared with preoperative scores. The mHHS (P=.005), SF-12 (P=.025), and VAS pain scores (P<.001) were all significantly better for refixation group compared with debridement group. Although most recent outcomes for both groups fell at mean 7 years' follow-up in comparison to 16 month and 3.5 year follow-up, the disparity between groups was greater in favor of labral refixation. Good-to-excellent results were 47.7% in debridement and 86.3% in refixation (p<.001), and failure rates were 29.6% (debridement) and 13.7% (refixation group) (p =.059). There were 4 revisions in the debridement group and 2 revisions in the refixation group. Conclusion. Longer term follow-up comparing focal labral debridement/excision to refixation revealed a decrease in patient related outcome scoring and good/excellent results in both groups. Ultimately, there was a greater drop in outcome measures and good/excellent results in the debridement group and better maintenance of results in the refixation group at mean 7 years follow-up.

Background: Arthroscopic stabilisation surgery for the shoulder remains a controversial choice of treatment for post traumatic anterior instability. We present the results of a consecutive initial series of 50 patients who were stabilised using a knotless labral repair technique. Methods: The study group included 41 men and 9 women with an average age of 26 years. 58% were affected on the dominant side. The average duration of preoperative syptoms was 3.8 years. 72% of patients had dislocations, whilst the remainder experienced subluxations. Each patient underwent a standardised procedure by the same surgeon with a regional interscalene block and/or general anaesthesia. Anchors were placed in the 3, 4 and 5 o’clock positions. Each patient was assessed using the Constant, Rowe and Walch-Duplay scores at an average of 18 months follow up (range 12–36 months). Results: At review 95% of shoulders remained stable. One patient had a true dislocation 6 months post surgery. One patient experienced a subluxation following a direct whilst skiing. 6 patients remained apprehensive. 3 patients had minor restriction of external rotation. The average Rowe score was 90.8, average Constant score was 89.9 and the average Walch-Duplay score was 81.4Conclusions: Early results indicate that capsulolabral reconstruction using the knotless suture anchor combined with a south to north capsular shift is an effective procedure in the treatment of post-traumatic anterior shoulder instability. This procedure may be performed as a day case under regional anaesthesia and is associated with a high index of patient satisfaction with a return to sporting activities

Labral tears are commonly associated with femoroacetabular impingement. We reviewed 151 patients (156 hips) with femoroacetabular impingement and labral tears who had been treated arthroscopically. These were subdivided into those who had undergone a labral repair (group 1) and those who had undergone resection of the labrum (group 2). In order to ensure the groups were suitably matched for comparison of treatment effects, patients with advanced degenerative changes (Tönnis grade > 2, lateral sourcil height < 2 mm and Outerbridge grade 4 changes in the weight-bearing area of the femoral head) were excluded, leaving 96 patients (101 hips) in the study. At a mean follow-up of 2.44 years (2 to 4), the mean modified Harris hip score in the labral repair group (group 1, 69 hips) improved from 60.2 (24 to 85) pre-operatively to 93.6 (55 to 100), and in the labral resection group (group 2, 32 hips) from 62.8 (29 to 96) pre-operatively to 88.8 (35 to 100). The mean modified Harris hip score in the labral repair group was 7.3 points greater than in the resection group (p = 0.036, 95% confidence interval 0.51 to 14.09). Labral detachments were found more frequently in the labral repair group and labral flap tears in the resection group. No patient in our study group required a subsequent hip replacement during the period of follow-up.

This study shows that patients without advanced degenerative changes in the hip can achieve significant improvement in their symptoms after arthroscopic treatment of femoroacetabular impingement. Where appropriate, labral repair provides a superior result to labral resection.
