Pain and swelling, which may lead to inhibition of the extensor mechanism and ultimately a delay in rehabilitation, are common complications of knee arthroscopy. Cryotherapy is the most often used means of decreasing both knee edema and discomfort. A number of methods have been used to provide cold pressure dressings, including ice and elastic bandages. Commercial devices, such as the Cryo/Cuff, also have been developed to provide similar beneficial effects. This article describes a multicenter randomized study undertaken to determine whether the Cryo/Cuff or the ice and elastic bandage offers the greatest convenience and relief of pain. One hundred two patients between the ages of 18 and 65 scheduled to undergo knee arthroscopy were enrolled. Postoperatively, the Cryo/Cuff patients required significantly less pain medication than those patients using the ice and elastic wrap. The Cryo/Cuff patients also expressed a high level of satisfaction with the effectiveness and convenience of the therapy. There were no differences between either group in the amount of pain reported, or preoperative and postoperative examinations in regard to knee range of motion and thigh circumference. These results indicate that the Cryo/Cuff is a useful adjunct in the rehabilitation of knee arthroscopy patients.
疼痛和肿胀是膝关节镜检查常见的并发症，可能导致伸肌机制受到抑制，最终延迟康复进程。冷冻疗法是减轻膝关节水肿和不适最常用的方法。人们采用了多种方法来提供冷压敷料，包括冰块和弹性绷带。还开发了一些商业设备，如Cryo/Cuff，以提供类似的有益效果。本文描述了一项多中心随机研究，旨在确定Cryo/Cuff还是冰块与弹性绷带能带来最大的便利性和疼痛缓解效果。102名年龄在18至65岁之间计划接受膝关节镜检查的患者参与了该研究。术后，使用Cryo/Cuff的患者比使用冰块和弹性绷带的患者需要的止痛药物明显更少。使用Cryo/Cuff的患者对该疗法的有效性和便利性也表示高度满意。两组在报告的疼痛程度、膝关节活动范围和大腿围度的术前及术后检查方面均无差异。这些结果表明，Cryo/Cuff是膝关节镜检查患者康复过程中的一种有用辅助工具。
