Clinical Outcome of Arthroscopic Lateral Release for Lateral Patellar Compression Syndrome

Clinical Outcome of Arthroscopic Lateral Release for Lateral Patellar Compression Syndrome

We performed 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 release in Erbil Teaching Hospital, PAR Private Hospital and Hawler Private Hospital between December 2016 and August 2019.
