Pain. Rule out patellar dislocation/chondromalacia, ACL injury, meniscal pathology. MENISCI: The menisci appear normal.ARTICULAR CARTILAGE: I see no focal articular cartilage defects.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: There is focal increased signal intensity within the lateral fibers of the proximal patellar tendon at its attachment to the patella, likely representing a combination of focal tendinosis and partial-thickness undersurface tearing. There is a small amount of edema within the underlying inferior pole of the patella. Distally, there is ossification within the patellar tendon just proximal to its insertion on the anterior tibial tubercle that may reflect prior injury/Osgood-Schlatter disease; however, I see no edema at this location currently. The quadriceps tendon appears normal. The tibial tubercle to trochlear groove distance and the Insall-Salvati ratio are within normal limits.ADDITIONAL
Focal tendinosis and undersurface tearing of the proximal patellar tendon.
