Acute patellar dislocations. The natural history

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanics

Background:

• Primary patellar dislocation is a common knee injury.
• Recurrence and persistent anterior knee pain are significant concerns for patients.

Purpose of the Study:

• To evaluate treatment outcomes for primary patellar dislocations.
• To identify factors influencing recurrent dislocations and long-term symptoms.

Main Methods:

• Retrospective analysis of 27 patients with primary patellar dislocations.
• Comparison of outcomes between immobilization/physiotherapy and immediate surgical stabilization.

Main Results:

• Patients with predisposing factors (malalignment, abnormal patellar configuration, prior instability) showed higher recurrence rates.
• Operative intervention may reduce recurrence in high-risk individuals.
• 30-50% of patients experienced persistent instability or anterior knee pain regardless of treatment.

Conclusions:

• Predisposing factors significantly increase the risk of recurrent patellar dislocation.
• Surgical intervention might be beneficial for specific patient groups.
• A substantial percentage of patients continue to experience symptoms post-primary dislocation.
