📝 Abstract:
Aims: This prospective study evaluated the effects of distal femoral extension/shortening osteotomy (DFEO/DFSO) combined with patellar tendon advancement (PTA) on gait, functional mobility, quality of life, and coronal knee alignment in patients with spastic diplegic cerebral palsy (CP) and crouch gait.🔗https://doi.org/10.1016/j.jbmt.2026.05.040
Methods: Fifteen patients (29 limbs analyzed) with GMFCS levels II–III underwent DFEO/DFSO + PTA. Preoperative and postoperative assessments included gait analysis, radiographic evaluation, physical examination, Functional Mobility Scale (FMS), and Cerebral Palsy Quality of Life (CPQOL) questionnaire.
Results: Knee flexion contracture improved markedly from 25.7° to 1.5° (p<0.001). Significant improvements were observed in gait mechanics, functional mobility, and quality of life. CPQOL scores increased from 50 to 66 points (p<0.001). Although postoperative coronal knee alignment was not associated with overall functional outcomes, patients achieving near-normal valgus alignment (5°–7°) demonstrated reduced ankle dorsiflexion during stance.
Conclusion: DFEO/DFSO combined with PTA effectively improves knee mechanics, gait performance, functional mobility, and patient-reported well-being in individuals with crouch gait due to cerebral palsy. While coronal alignment variability did not influence overall functional outcomes, it may affect distal joint biomechanics during gait.
