Ninety-seven patients with 99 total knee arthroplasties were operated on by a surgeon in the first 3 years of his surgical career. Complete survival data were available for all 99 knees. The cases were reviewed at a minimum of 10 years after their initial operation, but as 37 patients had died before reaching 10 years, the average follow-up was 8 years 8 months with a maximum of 12 years 4 months. Ninety-one patients had osteoarthritis, five had rheumatoid arthritis, and three had juvenile chronic arthritis. No patients were lost to follow-up. Four required revision. The 10-year survival rate, using revision for all causes as an end-point, was 94.96%. The survival rate for aseptic loosening was 97.04%. The survival rate for loose joints that had not been revised was 94.13%. Three of the four revisions occurred in the first 6 patients operated upon, suggesting there may be a learning curve for surgeons at this stage in their career.
在一位外科医生外科职业生涯的头3年里，他为97名患者实施了99例全膝关节置换手术。所有99个膝关节均有完整的生存数据。这些病例在初次手术后至少随访了10年，但由于37名患者在达到10年之前死亡，平均随访时间为8年8个月，最长为12年4个月。91名患者患有骨关节炎，5名患有类风湿关节炎，3名患有青少年慢性关节炎。没有患者失访。4例需要翻修。以因各种原因进行翻修为终点的10年生存率为94.96%。无菌性松动的生存率为97.04%。未进行翻修的松动关节的生存率为94.13%。4例翻修中有3例发生在最初接受手术的6名患者中，这表明在这个阶段外科医生的职业生涯中可能存在学习曲线。
