There are two types of genu recurvatum: one with bone deformity, which responds well to osteotomy, and one with posterior soft-tissue laxity with secondary bone changes. To date, no reliable treatment short of arthrodesis has been effective for the second type. An operation for this type of genu recurvatum (post-poliomyelitic) is described: a soft-tissue reconstruction of the lax tissues posterior to the knee joint done in three layers. The operation was done on sixteen knees in fourteen patients, with an average follow-up of four years and three months. The average recurvatum before surgery was 42 degrees and at the time of follow-up it was 6 degrees. Preliminary surgery is often required and precise surgical technique and prolonged bracing after surgery also are needed. All but one patient was made brace-free provided the limb operated on was not flail.
一种是伴有骨畸形的，对截骨术反应良好；另一种是伴有后方软组织松弛及继发性骨改变的。迄今为止，除关节融合术外，尚无可靠的治疗方法对第二种类型有效。本文描述了针对这种类型（小儿麻痹后遗症后）膝反屈的一种手术：对膝关节后方松弛组织进行三层软组织重建。该手术在14例患者的16个膝关节上实施，平均随访4年零3个月。术前平均反屈角度为42度，随访时为6度。通常需要进行初步手术，还需要精确的手术技术以及术后长时间使用支具。除1例患者外，只要接受手术的肢体不是连枷样的，所有患者术后均无需使用支具。
