Femoral component sizing and positioning is an essential component of performing a successful total knee arthroplasty. Failure to size or position the femoral component correctly can result in reduced range of motion, instability, soft-tissue impingement, and irritation. The following is a description of a novel technique that allows the surgeon to use an intercondylar autograft to translate the femoral component in the mediolateral direction and avoid the consequences of mediolateral femoral component overhang.
股骨部件的尺寸确定和定位是成功进行全膝关节置换术的重要组成部分。股骨部件尺寸确定或定位不当会导致活动范围减小、不稳定、软组织撞击和刺激。以下是一种新技术的描述,该技术允许外科医生使用髁间自体移植物在内外侧方向平移股骨部件,避免股骨部件内外侧悬垂的后果。
