Twenty-nine soft tissue releases for knee flexion contracture were performed in 23 children 2-15 years of age with juvenile chronic arthritis. The average duration of knee joint involvement was 4.6 years (range 1-11 years), and the mean age at operation was 8.6 years. Twenty-one of the 29 knee joints had a fixed flexion deformity exceeding 15 degrees preoperatively. Twenty-five knees were followed up for a mean period of 3.9 years (range 1-8 years), at which time only eight knees had a flexion deformity exceeding 15 degrees. There was a lasting effect of the release operations, and no significant complications were encountered. It is concluded that the procedure is worthwhile.
对23名2至15岁患幼年型慢性关节炎的儿童进行了29次膝关节屈曲挛缩软组织松解术。膝关节受累的平均时长为4.6年（范围1至11年），手术时的平均年龄为8.6岁。29个膝关节中有21个术前存在超过15度的固定性屈曲畸形。对25个膝关节进行了平均3.9年（范围1至8年）的随访，此时只有8个膝关节存在超过15度的屈曲畸形。松解手术有持久效果，且未出现明显并发症。得出的结论是该手术是值得的。
