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.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Lysholm Knee Score	Eight sections are assessed to produce an overall score on a scale of 0 to 100. Then an assignment is given as "excellent" for 95 to 100 points; "good" for 85 to 94 points, "fair" for 65 to 84 points, or "poor" for less than 65 points	12 months
