The results of arthrolysis of a stiff knee are often poor due to post-operative pain preventing early active mobilization that is so essential. Adequate analgesia may be ensured by the use of continuous anaesthesia via an epidural catheter, and in combination with continuous passive motion such analgesia is able to maintain, and often improve, the range of movement obtained at surgery. 22 patients treated in this way showed an improvement in the range of movement of between 39 and 120 degrees. Patients with post-traumatic knee stiffness achieved an average improvement in the range of movement of 93%, while those with stiffness following infection only improved by 55% on the average. The pre-operative loss of movement does not appear to determine the end result: the aetiology of the stiffness is more important.
膝关节僵硬行关节松解术后的结果往往不佳，原因是术后疼痛妨碍了至关重要的早期主动活动。通过硬膜外导管进行持续麻醉可确保充分镇痛，并且与持续被动运动相结合，这种镇痛能够维持并常常改善手术中获得的活动范围。以这种方式治疗的22例患者的活动范围改善了39至120度。创伤后膝关节僵硬的患者活动范围平均改善了93%，而感染后僵硬的患者平均仅改善了55%。术前的活动丧失似乎并不决定最终结果：僵硬的病因更为重要。
