目的 介绍自行研究设计的治疗膝关节僵直的外固定支架和缆线渐进牵拉装置(PSD),探讨其用于动物实验的疗效.方法 PSD包括3个部分:大腿双边平面外固定支架、小腿双边平面外固定支架和缆线系统.3只成年左膝关节僵直山羊采用PSD(4次/d,每次紧缩2～4 mm)进行左膝关节的逐步牵拉3周.3周后拆除山羊左下肢PSD.分别记录术前、拆除PSD当天、拆除PSD 1周后左膝关节最大屈曲度数.结果 3只山羊术前、拆除PSD当天及拆除PSD 1周后的膝关节屈曲角度平均分别为9.0°±3.6°、112.2°±17.7°和110.1°±15.5°.PSD治疗3周后左膝关节屈曲度数较术前明显改善,平均矫正103.2°.结论 PSD用于实验山羊左膝关节僵直牵拉效果肯定,具有较好的临床应用价值.

Objective To evaluate a self-designed novel progressive stretching device (PSD) for stiff knee in an animal experiment. Methods An animal model of left stiff knee was created in 3 adult goats. The PSD was used to put the left stiff knee in gradual traction for 3 weeks (4 times per day and 2 to 4mm per time) before it was removed. The maximum flexion degrees of the left knee were recorded before traction, the day of removal of the PSD and one week after removal of the PSD. Results The maximum flexion degrees of the]eft knee before traction, the day of removal and one week after removal of the PSD were 9. 0°± 3. 6°, 112. 2°± 17.7° and 110. 1 °± 15.5 °, respectively. No significant loss of the maximum flexion was observed one week after removal of the PSD. After 3 weeks of treatment with PSD, the maximum flexion degree of the left knee was significantly improved, with a mean correction of 103.2°. Conclusion The self-designed PSD may be used for treatment of stiff knee in clinical practice.
