胫骨内侧开放楔形高位截骨治疗膝关节内侧间室骨关节炎的短期疗效

目的 探讨胫骨高位截骨(HTO)治疗膝关节内侧间室骨关节炎的短期疗效。 方法 选取2015年1月至2016年1月行胫骨高位截骨患者20例(共26膝)。采用美国膝关节协会评分(AKS)、美国西大略湖和麦克马斯特大学骨关节炎指数评分(WOMAC)及视觉模拟评分(VAS),测量胫骨近端内侧角(MPTA)和股胫角(FTA)等术前、术后指标对HTO治疗膝关节内侧间室骨性关节炎的疗效进行评估与分析。 结果 20例患者均获得随访,随访时间3~12个月,患者术后膝关节疼痛、下肢力线均明显改善。1例刀口浅表感染,其他恢复良好、无并发症。患者术后AKS评分、WOMAC评分、VAS评分、MPTA和FTA角度与术前相比,差异有统计学意义(P<0.05)。 结论 HTO纠正了下肢异常力线的分布,消除或缓解膝关节疼痛,延缓膝关节退行性病变的进展,短期获得较好的临床效果,中远期疗效有待进一步随访跟踪和研究。

Short-term curative effect of open wedge high tibial osteotomy in the treatment of medial compartment knee osteoarthritis

Objective To observe the short-term curative effect of high tibia osteotomy(HTO)in the treatment of knee medial compartment osteoarthritis. Methods A total of 20 patients(26 knees)treated during Jan. 2015 and Jan. 2016 were involved. The curative effect was evaluated using American knee society(AKS), Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC), visual analogue scale(VAS), medial proximal tibial angle(MPTA), and femorotibial angle(FTA). Results During the follow-up of 3-12 months, both knee joint pain and lower limb strength were significantly improved. Superficial infection occurred in 1 case and no other complications were observed. The postoperative AKS score, WOMAC score, VAS score, MPTA and FTA were significantly improved(P<0.05). Conclusion HTO can correct the abnormal force distribution of lower extremities, relieve or eliminate knee pain, and delay the progress of the knee joint degeneration, thus showing good short-term curative effect. The long-term efficacy needs to be further observed.
