BACKGROUND
Unicompartmental knee arthroplasty (UKA) is an underutilized implant for medial tibiofemoral arthritis despite proven benefits in performance and reduced complications. This is likely related to registry recorded higher revision rates compared with total knee arthroplasty. It is our feeling that better component alignment resulting from the usage of computer-assisted surgery should improve longer-term functional results and survival of UKAs.
METHODS
Between August 2003 and June 2007, 265 medial UKAs were performed in 264 consecutive patients using navigation.
RESULTS
Eighty-eight women and 176 men with an average age of 51.7 (±4.63) years were assessed for function and survival over a follow-up period of 92.6 (63-120) months (7.7 years). The final survival rate over 5 years for this cohort was 97.6% at 5 years.
CONCLUSION
We conclude that computer-assisted UKA, to treat medial tibiofemoral joint arthritis, produces 5-year survival rates that are comparable with total knee arthroplasty.
背景
尽管单髁膝关节置换术（UKA）在性能方面已被证实具有优势且并发症减少，但对于胫股内侧关节炎而言，它仍是一种未得到充分利用的植入物。这可能与登记数据显示其翻修率高于全膝关节置换术有关。我们认为，使用计算机辅助手术实现更好的组件对线应能改善UKA的长期功能结果和生存率。
方法
2003年8月至2007年6月期间，对264例连续患者使用导航技术进行了265例内侧UKA手术。
结果
对88名女性和176名男性进行了评估，他们的平均年龄为51.7（±4.63）岁，随访时间为92.6（63 - 120）个月（7.7年）。该队列5年时的最终生存率为97.6%。
结论
我们得出结论，计算机辅助UKA治疗胫股内侧关节关节炎的5年生存率与全膝关节置换术相当。
