我们报告了一项前瞻性研究，采用多变量分析，在平均随访23.6个月时，对74例患者（共83个关节）的全膝关节置换术后影响活动范围的因素进行了分析（12 - 41），所有患者均诊断为骨关节炎，膝关节协会系统评分低于60的严重残疾膝关节，内翻畸形，膝关节既往无手术史，植入相同假体，手术技术相似，术后无影响关节活动范围的并发症，影响关节置换术后关节活动范围的最重要因素是术前屈曲范围和患者体重，术后12个月内，患者的屈曲度和屈曲挛缩均得到明显改善，术前活动受限的患者在最后一次随访时获得了满意的改善。
We report a prospective study, using multivariate analysis, of the factors which influence the range of movement after total knee arthroplasty in 74 patients with 83 arthroplasties at a mean follow-up of 23.6 months (12 to 41), All the patients had a diagnosis of osteoarthritis, a severely disabled knee with a Knee Society system score of less than 60, varus deformity, no previous surgery to the knee, identical prostheses implanted with a similar surgical technique, and no postoperative complications which may have affected the range of movement.The most important factors which influenced the range of movement after arthroplasty were the preoperative range of flexion and the body-weight of the patient, There was a significant improvement in flexion and reduction of flexion contracture at each successive review up to 12 months after operation, Patients with restricted movement before operation showed a satisfactory gain at final review.
