Patellar tendinopathy

Case contributed by Domenico Nicoletti


Runner with right knee pain for about three months.

Patient Data

Age: 35 years
Gender: Male

Right knee joint


Marked thickening and increased signal intensity of the proximal patellar tendon where intratendinous lesion is recognizable. In addition, there is concomitant deep infrapatellar bursitis with edema of the Hoffa’s pad and edema of the bone marrow in the inferior pole of the patella at the site of tendon’s attachment. The remaining objectivity is normal.

Case Discussion

A normal patellar tendon should not exceed 7 mm in AP diameter. In severe cases, partial or full thickness tears, with and without avulsion of the patellar apex, may be identified.
