Pdf Summary
The study question focuses on identifying key aspects of posterior cruciate ligament (PCL) injury. The correct response to the question is option E: a co-existing posterolateral corner injury would indicate the necessity for operative repair. Isolated PCL tears are less frequently treated surgically unless accompanied by other ligamentous damages, such as chronic symptomatic PCL tear or a posterolateral corner injury, which are common surgical indications.<br /><br />Answer A is incorrect because the most frequently associated ligament injury with a PCL tear is a posterolateral corner injury, not a tear of the lateral meniscus. In terms of injury mechanics, Answer B is incorrect because the PCL's primary function is preventing posterior tibial translation rather than acting primarily as a restraint to internal rotation of the knee. Answer C is incorrect because current literature does not support the notion that operative treatment is universally necessary for all complete PCL tears; sometimes non-operative treatment may suffice. Lastly, Answer D is also incorrect as it suggests focusing on strengthening the hamstrings for rehabilitation, whereas rehabilitation should actually aim to limit hamstring activity to prevent further posterior translation of the tibia.<br /><br />The references provided include a review of the current literature on PCL injuries, highlighting updates and the common surgical indications for such injuries, emphasizing the importance of understanding associated injuries when determining treatment.
