Reconstruction of nonrepairable acetabular labral tears with allografts: mid-term results.

Abstract

Many labral tears are nonrepairable. For these cases, labral reconstruction procedures may be considered in order to restore the joint fluid seal and prolong hip longevity. The aim of this study was to describe the clinical and functional outcomes of a series of cases with nonrepairable labral tears that underwent labral reconstruction with tendon allografts. The hypothesis was that labral reconstruction would provide good clinical outcomes. A cohort of 20 patients with nonrepairable labral tears, which underwent to labral grafting mainly by means of arthroscopic assisted anterior mini-open approach, were included in this study. The study period was comprised between July 2008 and September 2013. DCS-score resulted in 17 satisfactory results, whereas Nonarthritic Hip Score (NAHS) resulted in mean improvement of 39 points. 1 retrieved allograft demonstrated 8 weeks after implantation new whole revascularisation. We concluded that labral reconstruction with tendon allograft provides relief of painful symptoms, and represents a reliable alternative for patients with nonrepairable labral tears that are not yet candidates for a joint replacement procedure.
