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

BACKGROUND: 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.

AIMS: 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.

METHOD: 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.

RESULTS: 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.

CONCLUSIONS: 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.
