Posterior cruciate ligament injury

Case contributed by Dr Varun Babu

Presentation

Locking of knee with difficulty in climbing and walking.

Patient Data

Age: 25 years
Gender: Male
Modality: MRI

Swollen up posterior cruciate ligament with intrasubstance PD, T2 and STIR hyperintense signals along the direction of the fibres with preserved alignment. No other internal derangement. 

Case Discussion

Encountering a posterior cruciate ligament injury is not a daily routine unless you are a sports radiologist. Accounting for approximately 10% of knee injuries, this is an example of a contused posterior cruciate ligament with disruption of few of the internal fibres while the ligament per se remains intact. No secondary signs of tibial translation or any bone marrow changes seen in this case.
