Open Versus Arthroscopic Release for Lateral Patellar Compression Syndrome: Comparative Study

Chronic anterior knee pain with a stable patella is often associated with overload and increased pressure on the lateral facet due to pathologic lateral soft-tissue restraints. "Lateral pressure in flexion" is a term describing the pathologic process of increasing contact pressure over the lateral patellar facet as knee flexion progresses. Eighty patients were involved in this study, and it was divided into 2 random groups; Group A (40 patients)(odd number) were treated with open release after diagnostic arthroscopy and Group B (40 patients)(even number) were treated by arthroscopic release. All these patients are diagnosed as lateral patellar compression syndrome depending on clinical features, MRI and diagnostic arthroscopy. All patients were followed by Lysholm knee scaling score before surgery and two weeks , six weeks then 6 months after surgery.

About this study

This study was done by two orthopedic surgeons working in three hospitals from March 2016 to April 2018, Eighty patients were involved in this study, and it was divided into 2 matched groups; Group A (40 patients) were treated with open release after diagnostic arthroscopy and Group B (40 patients) were treated by arthroscopic release. All these patients are diagnosed as lateral patellar compression syndrome depending on clinical features, MRI ( figure 1)and diagnostic arthroscopy. All patients were followed by Lysol knee scaling score before surgery , two weeks , six weeks then 6 months after surgery. The two groups are matched related to age and gender. 52 patients are females and age ranged from 21-48 years.
