Problems can include inflammation or degeneration of the tendons (tendonitis and tendinosis); inflammation due to tissues rubbing inside the joint (medial plica syndrome) or outside the joint (such as iliotibial band friction syndrome).
The mechanism of injury was likely to have been nontraumatic in nature or as a result of repetitive microtrauma (i.e., friction and/or shear force resulting from medial plica syndrome) rather than a typical cause of chondral injury (such as acute trauma or twisting injury).
Trauma with repetitive knee movement leads to inflammation and thickening of the plica, resulting in medial plica syndrome. (20,38) Initial inflammation may be triggered by blunt trauma, a sudden increase in activity, or transient synovitis.
A recent systematic review found this test to be more diagnostically accurate than an MRI (sensitivity of the test is 90% and specificity is 89%, vs 77% and 58%, respectively, for MRI) for detection of medial plica syndrome. Ultrasound is almost as accurate, with a sensitivity of 90% and specificity of 83%.
