Medial-parapatellar-arthrotomy is the standard approach for total knee replacement(TKR). No studies have clarified the outcomes as quadriceps-strength-recovery (QS) and safety of Continuous-locking-suture-technique(CLS) for the arthrotomy-repair.
Patients were randomly assigned into a CLS(n = 40) and an interrupted-horizontal-mattress(IHM, n = 40). QS, visual-analog-scale(VAS), modified-timed-up-and-go(TUGT) test, Western-Ontario-and McMasters-Universities-Osteoarthritis-Index[WOMAC] and Knee-Society-Score[KSS] were followed for 6 months'.
A significantly-shorter capsular-closure-time in CLS(233 ± 40 VS 388 ± 47 sec)(p < 0.0001). There were insignificant difference in QS, VAS, TUGT, WOMAC and KSS during the 6-month follow-up period(p > 0.05 all). No wound complications were found.
CLS with braided-suture is safe and effective as demonstrated a recovery of the QS and knee function outcome comparable to IHM.

髌旁内侧关节切开术是全膝关节置换术(TKR)的标准入路。尚无研究阐明连续锁定缝合法(CLS)用于关节切开修复时股四头肌力量恢复(QS)情况及安全性。
将患者随机分为连续锁定缝合法组(n = 40)和间断水平褥式缝合法组(IHM,n = 40)。对QS、视觉模拟评分法(VAS)、改良计时起立行走测试(TUGT)、西安大略和麦克马斯特大学骨关节炎指数[WOMAC]以及膝关节协会评分[KSS]进行为期6个月的随访。
连续锁定缝合法组的关节囊闭合时间显著缩短(233 ± 40秒对388 ± 47秒)(p < 0.0001)。在6个月的随访期内,QS、VAS、TUGT、WOMAC和KSS方面差异无统计学意义(p均> 0.05)。未发现伤口并发症。
编织缝线连续锁定缝合法安全有效,其股四头肌力量恢复及膝关节功能结果与间断水平褥式缝合法相当。
