Area of Science:

  • Orthopedic surgery
  • Pediatric orthopedics
  • Biomechanical engineering

Background:

  • Knee flexion deformity negatively impacts gait, causing inefficiency and discomfort.
  • Common causes include spina bifida, cerebral palsy, SCIWORA, and skeletal dysplasia.
  • Existing treatments may be invasive or unsuitable for immature patients.

Purpose of the Study:

  • To introduce and evaluate anterior stapling of the distal femur for treating knee flexion deformities.
  • To assess the efficacy and safety of this minimally invasive technique in pediatric patients.

Main Methods:

  • Anterior stapling of the distal femur was performed on 28 patients (47 knees).
  • Preoperative assessment included hamstring contracture, fixed knee flexion, and gait analysis.

  • The technique is minimally invasive, allowing immediate resumption of bracing and physical therapy.

    • Main Results:

    • Preoperative fixed flexion deformities (10-25 degrees, max 45) reduced to 0-11 degrees post-surgery.
    • One patient experienced staple extrusion; no other complications were reported.
    • The procedure was well-tolerated by patients.

    Conclusions:

    • Anterior stapling is a safe and effective treatment for mild to moderate knee flexion deformities in immature patients.
    • It serves as a viable alternative to osteotomy, enabling gradual correction through growth modulation.
    • The technique improves gait parameters and patient comfort.
