Background
The purpose of the study was to compare the clinical results of arthroscopic labral repair using knot-tying and knotless suture anchor techniques for patients with labral tears.
Methods
From September 2012 to May 2013, we performed a randomized, prospective analysis of 40 hips with labral tears treated with arthroscopic labral repair via knot-tying (group A) or knotless suture anchors (group B). A total of 33 patients were treated for labral tears, and 7 of them received bilateral labral repair. Outcomes and intraoperative parameters were prospectively measured with the UCLA score, the modified Harris Hip Score (MHHS), the Hip disability and Osteoarthritis Outcome Score (HOOS), and the Hip Outcome Score (HOS).
Results
Three patients (3 hips) were lost to follow up. A total of 37 hips (30 patients) were finally analyzed: 19 hips in group A and 18 in group B. The mean traction time for group A and group B was 72.2 versus 68.7 min, respectively (p = 0.314). Although the clinical outcome scores in both groups improved between the initial and final visits, there was no difference in measurements parameters between the two groups. Survival rate, using reoperation or progression of osteoarthritis as the primary end points, was 100 %. 83 % of cases had excellent and good MHHS scores after 2 years of follow-up. During arthroscopic surgery, the drill penetrated the closing subchondral area or the joint in three hips. There was no progression of arthritic change at the latest follow-up.
Conclusions
Labral repair with either knot-tying or knotless suture anchor resulted in significant postoperative improvements and no difference between the two groups after 2 years of follow-up.
