The purpose of this study was to evaluate the outcomes of arthroscopic debridement and microfracture for isolated osteochondral lesions of the talus.
Twenty-four patients (25 ankles) with isolated osteochondral lesions of the talus were treated by arthroscopic debridement and microfracture. Nineteen men and five women with an average age of 38 years (range, 18–60 years) were followed for 32 months (range, 22–44 months).
American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scores were used. The results were excellent in 13 feet (52%), good in nine (36%), and fair in three (12%). Mean AOFAS scores improved from 61 points (range, 49–78) preoperatively to 89 points (range, 74–99) at final follow-up. Visual analogue scale (VAS) scores improved from 8 points (range, 4–8) to 2 points (range, 1–5), and Short Form-36 scores showed improvements in physical function, pain, social function, and general health. Also, we found that longer symptom duration had a negative effect on the outcome, as determined by AOFAS scores and VAS scores.
Arthroscopic debridement with microfracture for isolated osteochondral lesions of the talus appears to be a reliable, safe, and effective procedure that provides good clinical outcomes in most patients at midterm follow-up.
