Patients and Parents' Satisfaction and Self-Reported Evaluation After Single-Event Multilevel Surgery in Cerebral Palsy.

Purpose: The aim of this study was to analyze the results of single-event multilevel surgery (SEMLS) in cerebral palsy (CP) based on objective gait outcomes and self-reported evaluations.

Methods: In total, 258 patients with spastic diplegic CP, GMFCS I-III, who underwent SEMLS and with preoperative and postoperative gait analyses, were included in the SEMLS group (SG). The same database was used to compose the control group (CG) formed of 88 subjects who had performed at least 2 gait analyses and did not undergo surgical intervention between tests.
