The purpose of this study was to evaluate 10-year outcomes in cementless monobloc total hip arthroplasty (THA) in a group of hips with Legg-Calve-Perthes disease (LCPD).
We reviewed 71 patients (88 hips) who underwent cementless THA with a diagnosis of LCPD from 2003 to 2009. From the total of 71 patients, 34 men and 37 women with an average age of 49.94 years were included. The mean follow-up period was 10 years.
The mean Harris Hip Score improved significantly from 46.42 to 89.70. Similarly, the postoperative range of motion, hip dysfunction and osteoarthritis outcome score and SF-12 score also significantly improved. The mean leg lengthening was 22.1 mm. During the follow-up, eight complications were noted, including two cases of intraoperative femoral fractures, two cases of sciatic nerve paralysis, two cases of heterotrophic ossifications, one case of thigh pain and one case of dislocation. One revision was conducted for a periprosthetic fracture, and the survivorship at 10 years was 98.3%.
These data suggest that the monobloc stem can lead to satisfactory outcomes for clinical function, radiological evaluation, restoration of the normal limb lengths, complications, and survivorship among LCPD patients undergoing total hip arthroplasty.
本研究旨在评估一组患有Legg-Calvé-Perthes病（LCPD）的髋关节行非骨水泥型一体式全髋关节置换术（THA）的10年疗效。
我们回顾了2003年至2009年期间71例诊断为LCPD并接受非骨水泥型THA的患者（88髋）。在这71例患者中，纳入了34例男性和37例女性，平均年龄49.94岁。平均随访期为10年。
Harris髋关节评分均值从46.42显著提高至89.70。同样，术后活动范围、髋关节功能障碍和骨关节炎疗效评分以及SF-12评分也显著改善。平均下肢延长22.1毫米。随访期间，记录到8例并发症，包括2例术中股骨骨折、2例坐骨神经麻痹、2例异位骨化、1例大腿疼痛和1例脱位。因假体周围骨折进行了1次翻修，10年生存率为98.3%。
这些数据表明，对于接受全髋关节置换术的LCPD患者，一体式假体柄在临床功能、影像学评估、恢复正常肢体长度、并发症及生存率方面可带来满意的疗效。
