Both the medial collateral ligament (MCL) posterior Cruciate ligament (PCL) plays an essential role in normal knee function. MCL injuries may include a sprain or tear to the MCL.
Diagnosis
MCL and PCL ligament injuries are diagnosed with physical examination and advanced digital imaging
Treatment
The medial collateral Ligament injury can be treated nonsurgically or surgically.
Nonsurgical treatments include rest or a site-specific brace. Severe tears require surgery. Repairing the MCL may be accomplished through reconstructive surgery where the ligament is replaced with grafted material such as a tendon from a cadaver.
If the PCL is torn it will likely require reconstructive surgery. During this procedure, the surgeon will rebuild the torn PDL to restore function and reduce pain.
