Thirty patients had distal hamstring release with modified Green technique: 21 spastic diplegics, 8 spastic quadriplegics, and 1 spastic hemiplegic. The average age at the time of surgery was 6.9 years. The average follow-up was 2.5 years. Average improvement of 40 degrees in the popliteal angle was noted at follow-up. Twenty-three patients improved their gait pattern. Nine patients improved one level of walking ability. A popliteal angle over 50 degrees was defined as recurrent. On the basis of this criterion, the recurrence rate was 12.5% (7/56 knees). In all recurrent cases, however, the tightness was less severe than preoperatively. Noncompliance on the part of parents was the chief reason for recurrence. Distal hamstring release is an effective procedure in treatment of cerebral palsy patients with flexion deformity.
30例患者采用改良格林技术行腘绳肌远端松解术：21例痉挛性双侧瘫、8例痉挛性四肢瘫和1例痉挛性偏瘫。手术时的平均年龄为6.9岁。平均随访时间为2.5年。随访时发现腘窝角平均改善40度。23例患者的步态模式得到改善。9例患者的行走能力提高了一个等级。腘窝角超过50度被定义为复发。根据该标准，复发率为12.5%（56个膝关节中的7个）。然而，在所有复发病例中，紧张程度均不如术前严重。家长不配合是复发的主要原因。腘绳肌远端松解术是治疗脑瘫屈肌挛缩患者的有效方法。
