Long‐term muscle changes after hamstring lengthening in children with bilateral cerebral palsy

Aim To evaluate short‐term (1y postoperatively; E1) and long‐term (at least 4y postoperatively; E2) changes in hamstring muscle‐tendon length ( MTL ) and lengthening velocity after hamstring lengthening in children with bilateral cerebral palsy ( CP ). Method Three‐dimensional gait analysis was performed in 19 children (16 males, 3 females; 36 limbs; mean age at surgery 9y [ SD 3y]; range 6–10y) with flexed knee gait, preoperative ankle...
