Knee motion following multiple soft-tissue releases in ambulatory patients with cerebral palsy.
Multiple soft-tissue releases (MSTRs) in cerebral palsy have been advocated to improve knee motion during gait. Forty-five extremities underwent MSTRs as recommended by preoperative gait analysis. Pre- and postoperative analyses were evaluated in relation to knee motion and foot progression angle. Maximum knee flexion during swing and the foot progression angle showed no significant change postoperatively. The total knee ROM and minimum knee flexion in stance improved significantly towards normal. The timing of maximum knee flexion and slope of the knee flexion curve at toe off improved with respect to age and number of previous surgeries. MSTRs increased knee ROM and improved the sequential timing and event progression during gait.
