【 摘 要 】

Category:Basic Sciences/BiologicsIntroduction/Purpose:Arthroscopic bone marrow stimulation techniques including excision with curettage and microfracture are recommended as initial treatments for osteochondral lesions of the talus (OLT). However, several reports have indicated that lesion size and location are important prognostic factors for the clinical outcomes. A cutoff point regarding the risk of clinical failure exists for a lesion size of approximately 15 mm diameter or 150 mm2 area. A recent study reported that shoulder-type lesions had significantly worse clinical outcomes than nonshoulder-type lesions. However, to the best of our knowledge, no previous reports have provided biomechanical data for how nonshoulder-type and shoulder-type OLT affect the clinical outcomes. The purpose of this study was to clarify the stress distribution in articular cartilage of the talus with nonshoulder-type and shoulder-type OLT using finite element (FE) analysis.Methods:The healthy 33-year-old male and 29-year-ol...
