Minimizing Redislocation Rates and Restoring Function After Patella Dislocation: A Critically Appraised Topic.

Area of Science:

• Orthopedic surgery
• Sports medicine
• Knee biomechanics

Background:

• Patella dislocation is a frequent knee injury leading to reduced function and pain.
• Instability increases the risk of recurrent patella dislocations.
• Treatment options include conservative physical therapy or surgical intervention.

Purpose of the Study:

• To compare the effectiveness of conservative therapy versus medial patellofemoral ligament (MPFL) surgery for treating patella dislocation.
• To evaluate the impact of these treatments on redislocation rates and patient-perceived knee function.

Main Methods:

• A critical appraisal of 3 studies comparing MPFL surgery (reconstruction or repair) with conservative management (physical therapy, bracing).
• Outcomes assessed included redislocation rates and knee function using the Kujala scale.
• Study designs included randomized controlled trials and a prospective controlled trial.

Main Results:

• All three studies reported significantly lower redislocation rates in the surgical group compared to the conservative group.
• MPFL reconstruction led to significantly higher perceived knee function at 2-year follow-up, but not at 1 year.
• No significant difference in knee function was observed between MPFL repair and conservative management at 2 years.

Conclusions:

• Moderate evidence supports MPFL surgery as superior to conservative treatment in reducing patella redislocation rates.
• MPFL reconstruction may improve patient-perceived knee function at 2 years post-surgery.
• MPFL repair did not show a significant functional benefit over conservative management at 2 years.
