Clinical Outcome of Arthroscopic Lateral Release for Lateral Patellar Compression Syndrome

Objective: In this study, we have evaluated the effects of isolated arthroscopic lateral retinacular release in lateral patellar compression syndrome according to Lysholm Knee Scoring Scale. Methods: a prospective case series study of 48 patients who suffered Lateral patellar compression syndrome who were diagnosed by clinical examination and confirmed by M.R.I. and failed conservative management and underwent isolated arthroscopic lateral patellar retinaculum. Results: There was significant improvement in Lysholm score, in particular for pain, using stairs and squatting. The procedure had a high mean satisfaction score of 83.15 post operatively which is significant compared to preoperative score which was 51.17 (p<0.001). Conclusion: Isolated patella retinaculum release can be effective for relieving anterior knee pain in isolated lateral patellar compression syndrome without significant instability or mal-alignment.
