背景资料：尽管胫骨部件松动被认为是非骨水泥型全膝关节置换术后的一个问题，但由于这种植入物具有长入和保存骨量的潜力，因此已在年轻患者中使用。然而，现代非骨水泥型种植体的中期和长期研究缺乏。我们之前报道了在60岁之前接受手术的患者中使用非骨水泥型多孔钽胫骨部件后的前瞻性5年结局。本研究的目的是确定10年时年轻患者的临床和影像学植入物存活率。
Background: Although tibial component loosening has been considered a concern after total knee arthroplasty without cement, such implants have been used in younger patients because of the potential for ingrowth and preservation of bone stock. However, mid-term and long-term studies of modern uncemented implants are lacking. We previously reported promising prospective 5-year outcomes after using an uncemented porous tantalum tibial component in patients who underwent surgery before the age of 60 years. The purpose of this study was to determine clinical and radiographic implant survivorship at 10 years in this large series of young patients.Methods: The original cohort included 79 patients (96 knees) who were
