Final answer:
The false statement is 'Mainly lateral and PF OA' regarding PCL injury. PCL injuries happen often from direct impacts that push the tibia backwards, and chronic cases can be harder to spot on MRI. Grades 1 and 2 are usually treated without surgery.
Step-by-step explanation:
The statement that is not true about PCL injury is 'Mainly lateral and PF OA'. Posterior cruciate ligament (PCL) injuries typically result from a direct impact to the front of the knee, such as in a car accident or during sports, pushing the tibia backwards relative to the femur.Grade 1 and 2 PCL injuries, which involve partial tears or stretching of the ligament, can often be treated non-operatively with physical therapy and rehabilitation. However, severe or complete tears (Grade 3 PCL injuries) may require surgical intervention to restore stability to the knee joint.
Chronic PCL injuries are indeed harder to diagnose compared to acute injuries with MRI due to the ligament's healing over time and the potential for scar tissue to form, which makes the imaging less clear.
Grade 1 and 2 PCL injuries are often treated non-operatively with physical therapy and rehabilitation exercises unless they are a part of multi-ligament knee injuries. However, Grade 3 injuries, where the ligament is completely torn, might require surgical intervention.
