    Summary

    Distal hamstring tendon release effectively corrected knee flexion deformities in children with neurological conditions. This surgery improved walking ability and independence with no recurrence over a five-year follow-up.

    Area of Science:

    • Pediatric Orthopedics
    • Neurological Surgery
    • Rehabilitative Medicine

    Background:

    • True knee flexion deformity in children often stems from neurological conditions like cerebral palsy and meningomyelocele.
    • This deformity can significantly impair functional mobility and independence.
    • Existing treatments may have limitations or complications.

    Purpose of the Study:

    • To evaluate the long-term efficacy of distal hamstring tendon release in pediatric patients with true knee flexion deformity.
    • To assess functional outcomes, including walking capacity and independence, following the surgical intervention.
    • To determine the complication rate and recurrence of deformity after the procedure.

    Main Methods:

    • A cohort of thirty-one children underwent distal hamstring tendon release for true knee flexion deformity.
    • Thirty cases, involving 55 knees, were available for long-term review.
    • Follow-up data were collected to assess functional outcomes and surgical complications.

    Main Results:

    • Long-term results were encouraging, with significant improvements observed in functional walking capacity and independence.
    • Nearly all cases demonstrated positive functional gains post-surgery.
    • No complications were reported, and no recurrence of the knee flexion deformity was noted during the average five-year follow-up period.

    Conclusions:

    • Distal hamstring tendon release is a safe and effective procedure for managing true knee flexion deformity in selected pediatric cases.
    • The surgery offers substantial long-term benefits for children with cerebral palsy and meningomyelocele.
    • This intervention can be recommended to improve mobility and quality of life in these patients.
