Abstract
Objective
This study aimed to evaluate the mid- to long-term clinical, functional, and radiological outcomes of osteochondral autograft transplantation (OAT) in patients with advanced-stage Freiberg disease.
Methods
This retrospective study included 19 adult patients with Smillie stage III–IV Freiberg disease who underwent OAT between 2016 and 2022. The study included 11 female and 8 male patients, with a mean age of 36.7- 11.8 years and a mean follow-up of 61.6 - 24.1 months. Functional outcomes were assessed using the visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society lesser metatarsophalangeal–interphalangeal (AOFAS-LMI) score, and metatarsophalangeal joint range of motion (ROM). Radiological evaluation included weight-bearing radiographs and magnetic resonance imaging to assess graft incorporation and joint morphology. Preoperative and postoperative outcomes were compared, and an anchor based receiver operating characteristic (ROC) analysis was performed to determine the minimal clinically important difference (MCID) for the AOFAS-LMI score.
