Stiffness is an uncommon but potentially debilitating complication following total knee replacement (TKR). The treatment of this condition remains difficult and controversial. We present the results of 13 patients who underwent open arthrolysis for stiffness. The mean time between TKR and arthrolysis was 14 months. The mean follow-up was 7.2 years (2 to 10). The mean range of movement prior to arthrolysis was 55 degrees . This increased to 91 degrees , six months after arthrolysis (p < 0.005). The improved range of movement was maintained during the follow-up period. No patient has required revision of their components. We have found arthrolysis to be a useful and successful approach to post-TKR stiffness.
僵硬是全膝关节置换术（TKR）后一种不常见但可能使人衰弱的并发症。这种病症的治疗仍然困难且存在争议。我们展示了13例因僵硬接受开放性关节松解术患者的结果。全膝关节置换术与关节松解术之间的平均时间为14个月。平均随访时间为7.2年（2至10年）。关节松解术前的平均活动范围为55度。关节松解术后6个月，这一范围增加到了91度（p < 0.005）。在随访期间，改善后的活动范围得以维持。没有患者需要翻修其假体组件。我们发现关节松解术是治疗全膝关节置换术后僵硬的一种有用且成功的方法。
