胫骨高位截骨术治疗膝关节骨关节炎

Long term follow up of patients with knee osteoarthritis after high tibial osteoarthritis

目的 研究胫骨高位截骨术治疗膝骨关节炎的长期疗效。方法 对 1983～ 2 0 0 0年间行胫骨高位截骨术的 10 7例 (15 6膝 )膝骨关节炎患者随诊 ,测量术前及复查时拍摄负重位X线片角度并对临床效果进行评价。结果 好的临床效果在术后 1～ 5年为 88% ,5～ 10年为 75 % ,10年以上为 6 3%。 1例在术后 8年做全膝置换术。结论 胫骨高位截骨术治疗膝关节骨性关节炎近期效果显著 ,中远期效果能较好的保持。截骨后行内固定有利于患者早期活动及恢复。

Objective To investigate the clinical result of knee osteoarthritis after high tibial osteotomy(HTO) in long term follow-up. Methods 107 patients of knee joint osteoarthritis performed with high tibial osteoarthritis between 1983 and 2000 was followed up. Standing anteroposterior radiograph of knee were taken for every patient. Results The clinical results of 137 knees(88%) were rated as good at 1 to 5 years follow-up.21 knees wre good at 5 to 10 years follow-up. And 5 knees were good at lest 10 years follow-up. Only one patient was done TKA 8 year after HTO. Conclusions The patients done HTO show excellent clinical results in short time follow-up.And the results of most patients was maintained in intermediate and long-term follow-up.The internal fixition allow patients early activity and recover quickly.
