If a doctor suspects a PCL tear, he or she will likely order an MRI and X-Rays. The doctor will also give a thorough knee examination to determine the laxity (looseness), strength, and pain points within the joint. Not all PCL injuries require surgery. See your physician to discuss options appropriate for your age and level of activity. Depending on desired level of activity and degree of involvement in sports, non-operative management may be adequate. However, a doctor has many methods at his or her disposal, should PCL repair or reconstruction surgery be necessary. PCL injuries are often accidental, but certain steps can minimize your risk for incurring one. Strengthening your hamstring, calf and quadriceps muscles may create a stronger, tighter knee joint that is more resistant to injury. Avoidance of contact sports also greatly reduces your risk for a PCL tear.
