Long & Short Term Kinematic Outcomes following Rectus Femoris Transfers in Ambulatory Children with Cerebral Palsy
Description
In this presentation, Rubini Pathy discusses a study investigating the outcomes of rectus femoris transfers in ambulatory children with cerebral palsy, particularly focusing on how these transfers impact kinematic outcomes related to gait. The study aims to clarify the effectiveness of the procedure in addressing stiffening gait caused by overactivity of the rectus muscle during the swing phase of walking. Pathy notes significant variability in existing literature concerning outcomes and predictors, underscoring the need for a structured evaluation of long and short-term results post-surgery.
The study includes a cohort of 119 children, average age 10, who underwent retrofemoral transfer. Key kinematic variables analyzed were peak knee flexion during swing, the timing of this peak flexion, and the range of motion from peak to terminal swing. Results indicate that approximately 59% of the participants saw significant improvement in knee flexion at one year post-operation, a benefit that was sustained over five- and ten-year follow-ups. Improvements were notably observed in responders who experienced an increase in flexion into the normative range, contrasting with nonresponders, who tended to lose range of motion.
Further analysis in the study reveals that a majority of children improved their timing of peak knee flexion, although most did not reach normal knee range motion. Additionally, outcomes were assessed to determine predictors of improvement; gymnastics level and preoperative involvement in key variables emerged as significant predictors. Pathy highlights the limitation of a high loss to follow-up, the retrospective nature of the study, and the exclusion of certain variables like selective motor control.
Concluding, Pathy emphasizes that while the majority of children benefited from rectus femoris transfers, the study calls for further exploration into the characteristics differentiating responders from nonresponders to optimize surgical outcomes.
