A total of 25 children (37 legs and 51 segments) with coronal plane deformities around the knee were treated with the extraperiosteal application of a flexible two-hole plate and screws. The mean age was 11.6 years (5.5 to 14.9), the median angle of deformity treated was 8.3 degrees and mean time for correction was 16.1 months (7 to 37.3). There was a mean rate of correction of 0.7 degrees per month in the femur (0.3 degrees to 1.5 degrees ), 0.5 degrees per month in the tibia (0.1 degrees to 0.9 degrees ) and 1.2 degrees per month (0.1 degrees to 2.2 degrees ) if femur and tibia were treated concurrently. Correction was faster if the child was under 10 years of age (p = 0.05). The patients were reviewed between six and 32 months after plate removal. One child had a rebound deformity but no permanent physeal tethers were encountered. The guided growth technique, as performed using a flexible titanium plate, is simple and safe for treating periarticular deformities of the leg.
共有25名患有膝关节周围冠状面畸形的儿童（37条腿，51个节段）接受了柔性双孔钢板和螺钉的骨膜外应用治疗。平均年龄为11.6岁（5.5至14.9岁），接受治疗的畸形中位角度为8.3度，平均矫正时间为16.1个月（7至37.3个月）。股骨平均每月矫正率为0.7度（0.3度至1.5度），胫骨平均每月矫正率为0.5度（0.1度至0.9度），若同时治疗股骨和胫骨则平均每月矫正率为1.2度（0.1度至2.2度）。10岁以下儿童矫正速度更快（p = 0.05）。在取出钢板后6至32个月对患者进行了复查。1名儿童出现了反弹畸形，但未遇到永久性的骨骺束缚。使用柔性钛板进行的引导生长技术治疗腿部关节周围畸形简单且安全。
