Case Report: Arthroscopic treatment of calcific periarthritis of the knee in the lateral and medial collateral ligaments.

ABSTRACT:

Objective

Calcific periarthritis, a well-recognized pathological condition of the shoulder joint, also represents an uncommon etiology of severe knee pain. Here, we present a case report of a patient with calcifications concurrently affecting both the lateral collateral ligament (LCL) and medial collateral ligament (MCL).

Case description

The 62-year-old woman presented with severe lateral knee pain and restricted range of motion in her right knee. The knee exhibited marked tenderness in the posterolateral region and slight swelling, and maintained ligamentous stability. X-ray imaging of the knee revealed well-defined calcific deposits bilaterally on the femoral condyles. MRI findings indicated hypointense signal areas in close proximity to the insertions of the LCL and MCL.
