摘要(Abstract):
[目的]调查国人类风湿关节炎中髌骨的厚度及解剖学特点,探讨髌骨置换术的方法和安全性。[方法]自2005年1月~2006年1月,对59例患者95个类风湿膝关节行全膝置换术,术中测量髌骨最厚处、最薄处和髌骨截骨后骨床的厚度以及安装髌骨假体后髌骨复合物厚度,术后对患者随访,观察膝前痛和髌骨骨折的发生率。[结果](1)截骨前髌骨的厚度测量为最高处(22.01±1.64)mm(18~26mm),最低处为(11.69±2.33)mm(6~16mm)。(2)截骨后髌骨的骨床厚度测量结果为(13.23±0.96)mm(11~16mm),其中11mm4膝(4.2%),12mm15膝(12.7%),13mm38膝(40%),14mm32膝(33.7%),15mm5膝(5.3%),16mm1膝(1.1%)。髌骨复合物的厚度平均为21.42mm(20~25mm),90.5%(86/95)的髌骨厚度在术后等于或稍低于原髌骨厚度。(3)术后随访轻度膝前痛3例,无髌骨骨折或髌骨松动病例。[结论](1)类风湿膝关节中髌骨的厚度小于国人正常髌骨厚度的均值。(2)类风湿膝关节髌骨置换时保留12~14mm厚度的骨床是一种安全的选择。(3)类风湿膝关节置换髌骨短期随访临床疗效肯定。
