This study on late-onset tibia vara in children found surgical correction effectively realigned the tibiofemoral angle. Most patients achieved good outcomes, indicating surgical intervention is beneficial for this condition.

Area of Science:

  • Orthopedics
  • Pediatric Surgery
  • Biomechanical Engineering

Background:

  • Late-onset tibia vara is a progressive condition causing genu varus deformity in children.
  • Obesity and knee pain are common comorbidities in affected pediatric patients.
  • Early surgical intervention may be necessary to correct the deformity and alleviate symptoms.

Purpose of the Study:

  • To evaluate the surgical outcomes of treating late-onset tibia vara in a pediatric cohort.
  • To assess the effectiveness of surgical correction in restoring normal tibiofemoral alignment.
  • To analyze the correlation between preoperative parameters and final clinical results.

Main Methods:

  • A retrospective study of 15 children diagnosed with late-onset tibia vara.

  • Surgical correction of tibiofemoral deformity.
  • Preoperative and postoperative assessment of tibiofemoral angle.
  • Clinical evaluation of outcomes at an average follow-up of 4 years 4 months.

    • Main Results:

    • The average preoperative tibiofemoral angle was 14 degrees of varus.
    • Postoperative follow-up showed an average tibiofemoral angle of 0 degrees.
    • Fifteen patients achieved good final results, with two fair and six poor outcomes.
    • The average age at surgery was 12 years.

    Conclusions:

    • Surgical correction of late-onset tibia vara effectively normalizes the tibiofemoral angle in pediatric patients.
    • The majority of surgically treated children experienced good to excellent outcomes.
    • Further research could explore factors influencing fair or poor results.
