We report a prospective case-controlled study which compared the outcome of knee replacement in seriously deformed and slightly deformed knees. There were 51 knees with varus or valgus deformity greater than 20 degrees matched for age, gender, disease, type of prosthesis and time of operation with a control group in which the alignment of the leg was within 5 degrees of normal. The clinical outcome at a mean 5.5 years was similar in the two groups. Some deformity persisted in 14 patients in the first group, 13 of whom were initially in valgus. These patients had a significantly poorer mean clinical outcome. Lateral dislocation or subluxation of the patella was found in four knees, all of which had had valgus deformity of 30 degrees or more.
我们报告了一项前瞻性病例对照研究，该研究比较了严重畸形膝关节和轻度畸形膝关节的膝关节置换结果。有51例内翻或外翻畸形大于20度的膝关节，在年龄、性别、疾病、假体类型和手术时间方面与对照组进行匹配，对照组下肢力线在正常范围内5度以内。两组平均5.5年时的临床结果相似。第一组有14例患者仍存在一些畸形，其中13例最初为外翻畸形。这些患者的平均临床结果明显较差。在4例膝关节中发现髌骨外侧脱位或半脱位，所有这些膝关节均有30度或以上的外翻畸形。
