38-year-old male with continued pain 12 weeks postop. Evaluate patellar tendon repair. MENISCI: The medial meniscus appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is focal blistering of the articular cartilage along the medial facet of the patella. The articular cartilage of the medial and lateral compartments appears normal. We see no bone contusions.LIGAMENTS: There is intermediate signal intensity within the proximal half of the PCL which may reflect degeneration or perhaps prior injury. The ACL appears intact. The LCL and MCL appear intact.EXTENSOR MECHANISM: There are tubular foci of abnormal signal intensity extending vertically through the patella, compatible with the patient's history of patellar tendon repair, with mild edema-type signal abnormality within the remainder of the patella that is nonspecific. The patellar tendon itself is markedly thickened with heterogeneous low to intermediate signal intensity with multiple foci of signal void. These findings likely represent a combination of tendinosis, scarring, and prior surgical intervention, but we see no fluid signal intensity within the tendon to confirm a tear. The quadriceps tendon also appears thickened and heterogeneous indicating tendinosis with small foci of increased signal intensity within the tendon at its patellar insertion, suggesting small interstitial insertional tears. There is thickening of the medial and lateral retinacular structures, presumably reflecting prior injury/scarring.ADDITIONAL
1. Thickened and heterogeneous patellar tendon indicating tendinosis and scarring, but we see no fluid-filled tear.2. Quadriceps tendinopathy and retinacular thickening.3. Blistering of the articular cartilage of the medial facet of the patella and other findings as above.
