Patellofemoral Instability: Preoperative Considerations and Postoperative Imaging.

Area of Science:

• Orthopedics
• Biomechanics
• Sports Medicine

Background:

• Patellofemoral instability is a prevalent condition, particularly in young female athletes.
• It leads to significant morbidity, including pain and accelerated osteoarthritis.
• Presentation ranges from acute dislocations to chronic instability.

Purpose of the Study:

• To detail the anatomy and biomechanics of the patellofemoral joint.
• To correlate these factors with the pathology of patellofemoral instability.
• To outline diagnostic and surgical management strategies.

Main Methods:

• Review of anatomical and biomechanical principles of the patellofemoral joint.
• Discussion of predisposing anatomical factors (e.g., trochlear morphology, tibial tubercle lateralization).
• Emphasis on clinical evaluation and multimodality imaging for diagnosis and surgical planning.

Main Results:

• Identification of key anatomical contributors to patellofemoral instability.
• Demonstration of the role of imaging in assessing predisposing factors and postoperative outcomes.
• Overview of surgical techniques targeting specific anatomical abnormalities.

Conclusions:

• Accurate diagnosis relies on integrating clinical findings with advanced imaging.
• Surgical management should address the underlying anatomical and biomechanical deficits.
• Effective treatment can mitigate pain, improve function, and prevent further joint degeneration.
