Summary
Pediatric patellofemoral instability often recurs in young patients. Identifying anatomic risk factors and considering earlier surgical intervention, like medial patellofemoral ligament reconstruction, can improve outcomes.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Sports Medicine
Background:
- Patellofemoral instability is prevalent in children and adolescents.
- Recurrence rates exceed 50% in skeletally immature patients.
- Anatomic risk factors are crucial for predicting recurrence.
Purpose of the Study:
- To review current evidence on risk factors for pediatric patellofemoral instability.
- To synthesize information on surgical techniques and outcomes.
- To guide clinical decision-making for managing this condition.
Main Methods:
- Literature review of current and latest evidence.
- Synthesis of data on predisposing anatomic risk factors.
- Analysis of surgical techniques and patient outcomes.
Main Results:
- Key predictors include trochlear dysplasia, patella alta, skeletal immaturity, and elevated tibial tubercle groove distance.
- Emerging evidence supports earlier surgical intervention for high-risk patients.
- Medial patellofemoral ligament reconstruction is a primary surgical treatment, with physeal-sparing options for immature patients.
Conclusions:
- Accurate identification of risk factors is essential for managing pediatric patellofemoral instability.
- Earlier surgical intervention may be beneficial for high-risk individuals.
- Medial patellofemoral ligament reconstruction and potential distal realignment procedures guide treatment strategies.
