Return to Sports After Bone Marrow-Derived Cell Transplantation for Osteochondral Lesions of the Talus

Abstract

Objective: Arthroscopic \"one-step\" technique based on bone marrow-derived cell transplantation (BMDCT) have achieved good results in repairing osteochondral lesions of the talus (OLT), overcoming important drawbacks of older techniques. It may be particularly adequate for the treatment of athletes in order to permit a safe and stable return to sports. The aim of this study was to report the results at 48 months of a series of athletes and the factors influencing the return to sports.

Design: Case series. A total of 140 athletes underwent a \"one-step\" BMDCT repair of OLT. All the patients had the cells harvested from the iliac crest, condensed and loaded on a scaffold, and then implanted. Patients were evaluated clinically by the American Orthopaedic Foot and Ankle Society (AOFAS) scores and Halasi score.

Results: AOFAS score improved from 58.7
