To investigate the effect of horizontal platform supported (HPS) prosthesis on cementless total hip replacement for surgical treatment of arthritis in a long-term follow-up study.
Clinical and radiographic follow-up of 65 consecutive primary cementless porous coated HPS total hip replacements, which were implanted in 60 patients between 1982 and 1989, was carried out.
The 53 hips in 50 patients were evaluated both clinically and radiographically. The average follow-up was 6.8 years (range: 5 to 12 years). According to the Harris hip score, 52 (98%) of the hips had sustained an excellent or good result with an average score of 92. At the time of final assessment, no patient experienced anterior thigh pain. There were two revisions performed early in the series due to technical failures. Radiographically, osteolysis and bone remodelling were assessed.
The findings suggest that the clinical and radiographic results after cementless total hip replacement for primary hip arthroplasty may be favourably influenced by the use of the proximal stress loaded HPS femoral component.
在一项长期随访研究中，探讨水平平台支撑（HPS）假体在非骨水泥型全髋关节置换治疗关节炎中的效果。
对1982年至1989年间为60例患者植入的连续65例初次非骨水泥型多孔涂层HPS全髋关节置换进行临床和影像学随访。
对50例患者的53髋进行了临床和影像学评估。平均随访6.8年（范围：5至12年）。根据Harris髋关节评分，52髋（98%）获得了优秀或良好的结果，平均评分为92分。在最终评估时，没有患者出现大腿前部疼痛。该系列早期因技术失误进行了2次翻修。通过影像学评估骨溶解和骨重塑情况。
研究结果表明，使用近端应力加载的HPS股骨组件可能会对初次髋关节置换的非骨水泥型全髋关节置换术后的临床和影像学结果产生有利影响。
