For Japanese individuals, deep bending is inevitable in their daily lives, such as during seiza sitting and kneeling. Thus, achieving a good post-operative range of motion is an important factor in improving patient satisfaction. Even normal knees often have a posterior tibial slope of more than 10°. We report the case of a 76-year-old woman who underwent proximal tibial osteotomy at 8° with the Vanguard Knee cruciate retaining total knee arthroplasty (TKA) system. She required the revision TKA 10 years later due to ultra-high-molecular-weight polyethylene wear and breakage of the posteromedial tibial component.
对于日本人来说，在日常生活中，如在正坐和跪坐时，深度弯曲是不可避免的。因此，实现良好的术后活动范围是提高患者满意度的一个重要因素。即使是正常的膝盖，胫骨后倾坡度通常也超过10°。我们报告了一例76岁女性的病例，她使用先锋膝关节保留交叉韧带全膝关节置换（TKA）系统进行了8°的胫骨近端截骨术。10年后，由于超高分子量聚乙烯磨损和胫骨后内侧组件断裂，她需要进行TKA翻修手术。
