Summary
There is no optimal treatment for large osteochondral defects of the talus or for lesions after failed primary surgical treatment. A metal implant has been developed for these cases. The authors report 15 patients with a large defect of the medial talar dome treated with this implant after failed prior surgical treatment. Various outcome measures were recorded prospectively, including numeric rating scales (NRS) of pain for different situations, American Orthopaedic Foot and Ankle Society (AOFAS) Ankle and Hindfoot clinical rating System, Foot and Ankle Outcome Score (FAOS), and Short Form 36 (SF-36). After one year follow-up, there was significant improvement in the NRS, AOFAS, four of five subscales of the FAOS, and the SF-36 physical component scale. There were four minor complications that resolved within the study period. On radiographs, there were no signs of progressive degenerative changes. These short term results are promising but more patients and longer follow-up are needed to draw firm conclusions.
