Description
Summary:Abstract Anthropometric features of Asians femora and their clinical relevance with regard to TKA are not rigorously investigated. We attempted to determine how well current prostheses accommodate femoral anthropometric features of Koreans and whether the presence of condylar or trochlear overhang or underhang adversely affects functional outcomes. We hypothesized that current prostheses do not accommodate Korean female femora well, and that overhang or underhang would adversely affect outcomes. Condylar and trochlear mediolateral (ML) widths and condylar anteroposterior (AP) heights were measured, and ML/AP ratios were calculated in 1025 osteoarthritic knees that underwent TKA. Besides gender difference, wide individual variation exists in condylar and trochlear widths and ML/AP aspect ratios for given AP heights. Size options of current prostheses could not cover the wide ranges of ML widths for given AP heights. The knees with condylar overhang more than 4 mm showed lower maximum flexion angle postoperatively ( P = 0.005).
