人工全膝关节置换术后患膝伸直障碍的影响因素分析

Analysis of the influencing factors of knee-extension disorder after total knee arthro-plasty

目的 探讨人工全膝关节置换术（TKA）后患者患膝伸直障碍的影响因素.方法 选取山西省某三甲医院近12年行TKA的152例有效病历为研究对象,采用自行设计的资料整理表对有效病历进行整理.结果 不同性别患者术后患膝伸直障碍比较,差异有统计学意义（P〈0.05）;术后未进行沙袋压迫的患者伸直障碍的发生率高于进行沙袋压迫的患者,差异有统计学意义（P〈0.05）;回归分析结果显示,TKA后患膝伸直障碍的影响因素为性别和沙袋压迫.结论 男性患者更应该注意加强TKA后患膝伸直的锻炼;术后患膝进行一定的加压练习有助于促进关节伸直.

Objective To explore the influencing factors of knee-extension disorder after total knee arthroplas-ty （ TKA） . Methods A total of 152 valid cases of patients with TKA treated in a certain Top-Three hospital of Shanxi Province during the past 12 years were selected, and the valid medical records were collected and analyzed by the self-designed data form. Results There were statistical significances in terms of the differernces of knee-extension disorder with different gender （ P〈0. 05 ） . The occurance rate of knee-extension disorder of patients without sandbags oppres-sion after surgery was higher than that of patients with sandbags oppression, and the difference was statistically signifi-cant （ P〈0. 05 ） . Regression analysis showed that the influencing factors of knee-extension disorder after TKA were gen-der and sandbags oppression. Conclusions Male patients should pay more attention to the strengthening of knee exten-sion exercise after TKA. Pressurized exercises after surgery helps to promote the extension of joints.
