This prospective study was conducted to demonstrate that the matte-finish Basis CL cemented endoprosthetic stem delivers good qualitative results after 10 years. Between January and December 1999, 205 consecutive hips (201 patients; 74.5 ± 6.8 years at surgery) underwent primary total hip arthroplasty with the Basis CL and the same acetabular cup (RM Classic cup) at a single institution. Follow-up data at 10 years was available for 120 hips (average follow-up of 8.9 years, ±2.9). Mean Harris Hip Score improved from 39.5 ± 16.8 at baseline to 75.9 ± 16.7 at 10-year follow-up (p<0.001). Four hips required revision during the study: three for infection and one for pain. There were no cases of aseptic loosening, implant migration, or stem fracture. Cumulative survival at 10 years was 97.4% with the endpoint of revision for any reason. In conclusion, results with the matte-finish cemented Basis CL indicated that it was safe and effective after medium-term follow-up.
本前瞻性研究旨在证明磨砂表面的Basis CL骨水泥型假体柄在10年后能带来良好的定性结果。1999年1月至12月期间，在单一机构中，205例连续的髋关节（201例患者；手术时年龄为74.5±6.8岁）接受了使用Basis CL和相同髋臼杯（RM Classic杯）的初次全髋关节置换术。120例髋关节有10年的随访数据（平均随访8.9年，±2.9）。平均Harris髋关节评分从基线时的39.5±16.8提高到10年随访时的75.9±16.7（p<0.001）。研究期间有4例髋关节需要翻修：3例因感染，1例因疼痛。没有无菌性松动、植入物移位或假体柄骨折的病例。以任何原因进行翻修为终点，10年的累积生存率为97.4%。总之，磨砂表面骨水泥型Basis CL的结果表明，中期随访后其安全有效。
