Arthroscopic percutaneous lateral patellar retinacular release.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Knee Biomechanics

Background:

• Patellofemoral pain syndrome (PFPS) is a common cause of knee pain.
• Lateral retinacular release is a surgical option for recalcitrant PFPS.
• Evaluating the efficacy of arthroscopic lateral patellar retinacular release is crucial for patient outcomes.

Purpose of the Study:

• To retrospectively evaluate the clinical outcomes of arthroscopic lateral patellar retinacular release.
• To assess patient-reported pain, physical examination findings, and objective strength measurements post-surgery.
• To determine the overall success rate and identify factors influencing outcomes.

Main Methods:

• Retrospective review of 34 arthroscopic lateral patellar retinacular releases in 26 patients.
• Assessment of residual pain and physical examination criteria.
• Objective measurement of quadriceps and hamstring strength using the Cybex II Isokinetic Dynamometer.

Main Results:

• Overall, 64.7% of knees showed improvement following the procedure.
• Excellent results were achieved in 9%, good in 53%, fair in 26%, and poor in 12% of cases.
• Objective strength measurements provided quantitative data on functional recovery.

Conclusions:

• Arthroscopic lateral patellar retinacular release can be an effective treatment for selected patients with patellofemoral pain.
• The procedure demonstrated a significant rate of improvement in knee function and pain reduction.
• Further research may explore patient selection criteria and long-term outcomes.
