The Effect of Containment Type on Clinical Outcome in Osteochondral Lesions of the Talus Treated with Autologous Osteochondral Transplantation:

摘要

Category:AnkleIntroduction/Purpose:Operative management for osteochondral lesions of the talus (OLT) can be broadly divided into reparative techniques, including bone marrow stimulation (BMS), and replacement techniques, including autologous osteochondral transplantation (AOT). Predictors of outcome of BMS have been established as lesion size, containment of the lesion, and previous surgery. Predictors of outcome of AOT or allograft transplantation have been established as body mass index and the requirement for greater than 2 grafts. However, containment of the lesions has not been assessed as a predictor of outcome in patients undergoing AOT to date. Therefore, the purpose of the current study is to clarify the effect of the containment of OLT on clinical and radiological outcomes in patients who underwent AOT procedure for the treatment of OLT.Methods:A retrospective cohort study comparing patients with contained type and uncontained type OLT was undertaken, to include all patients who underwent AOT pr...
