Summary

Hemiphyseal stapling effectively treats adolescent idiopathic genu valgum, improving knee alignment and reducing pain. This safe and well-tolerated procedure offers high patient satisfaction and avoids corrective osteotomies.

Area of Science:

  • Orthopedic Surgery
  • Pediatric Orthopedics
  • Biomechanical Engineering

Background:

  • Adolescent idiopathic genu valgum presents with anterior knee pain, patellofemoral instability, and gait abnormalities.
  • Untreated genu valgum can lead to long-term functional limitations and pain.

Purpose of the Study:

  • To evaluate the efficacy of hemiphyseal stapling as an ideal treatment for adolescent idiopathic genu valgum.
  • To assess clinical outcomes and radiographic improvements following hemiphyseal stapling.

Main Methods:

  • Retrospective review of 76 patients (152 knees) with adolescent idiopathic genu valgum treated with hemiphyseal stapling.
  • Clinical assessments included gait, limb length, alignment, and patellofemoral stability.
  • Radiographic evaluation of distal femoral angle (DFA), femoral tibial angle (FTA), and mechanical axis (MA) pre- and post-procedure.

Main Results:

  • Significant improvements observed in gait, clinical symptoms, and all measured radiographic parameters post-stapling.
  • Hemiphyseal stapling successfully corrected the anatomic malalignment associated with genu valgum.
  • No premature physeal closures were reported, indicating procedural safety.

Conclusions:

  • Hemiphyseal stapling is a safe and effective treatment for adolescent idiopathic genu valgum, alleviating symptoms and improving function.
  • The procedure demonstrates high patient satisfaction and obviates the need for more invasive corrective osteotomies.
  • This method provides a reliable solution for managing genu valgum in adolescents.
