Partial Hemiresurfacing of Osteochondral Defects of the Talus? Surgical Technique and Preliminary Report from Four Patients

Abstract Background: Osteochondral lesions of the medial talus (OLT) frequently lead to chronic ankle pain and osteoarthritis. Arthroscopic debridement, subchondral bone stimulation by drilling, and microfracturing are options for primary therapy in small lesions. In larger lesions, restoration of the talar dome contour seems to be a mandatory course of action. Methods: In a case series, we followed up four patients being treated with a focal resurfacing prosthetic due to large osteochondral talar lesions. In contrast to other studies, we can report on an off-label application to restore defects of the lateral t…
