This report is a prospective review of 450 low-friction arthroplasties (LFAs) performed by a single surgeon from 1972 to 1983 in a community hospital. The clinical results show sustained quality of the result over a maximum follow-up period of 11 years. The radiologic review shows a slight increase in the number and size of radiolucent lines with time. Bacteriologic studies confirm that clean-air technology reduces the bacteriologic contamination of the operating room and the wound. Deep infections occurred in 1.6% of cases. The most notable complication was failure to obtain bony union of the osteotomized trochanter in 14% of cases. The revision rate for aseptic loosening of the cup was 0.7% and of the femoral prosthesis 0.0%.
本报告是对一位外科医生于1972年至1983年在一家社区医院进行的450例低摩擦关节成形术（LFA）的前瞻性回顾。临床结果显示，在长达11年的最长随访期内，结果质量持续良好。影像学回顾显示，随着时间推移，透亮线的数量和大小略有增加。细菌学研究证实，洁净空气技术可减少手术室和伤口的细菌污染。1.6%的病例发生深部感染。最显著的并发症是14%的病例中截骨转子未能实现骨愈合。髋臼无菌性松动的翻修率为0.7%，股骨假体的翻修率为0.0%。
