The authors report the clinical and radiographic results at from six months to two years after the insertion of spherocentric knee prostheses in fourteen patients with rheumatoid arthritis and four patients with arthrosis of the knee. The results were satisfactory and there were no complications. This type of prosthesis has therefore become the treatment of choice in cases of varus or valgus deformity in excess of 30 degrees and those involving extreme instability. It is also an alternative after failures with other types of prosthesis.
作者报告了14例类风湿性关节炎患者和4例膝关节病患者植入球心膝关节假体后6个月至2年的临床和影像学结果。结果令人满意，且无并发症。因此，这种类型的假体已成为内翻或外翻畸形超过30度以及伴有极度不稳定情况的首选治疗方法。它也是其他类型假体失败后的一种替代选择。
