These letters represent 4 ligaments that make up the knee joint. While there are several smaller ligaments within the knee, these are the 4 main ones that people often injure, especially athletes.
ACL: Anterior Cruciate Ligament
PCL: Posterior Cruciate Ligament
MCL: Medial Collateral Ligament
LCL: Lateral Collateral Ligament
When you injure a ligament, it is usually from a traumatic event such as landing improperly, an abnormal force, and/or a collision. Most will experience pain immediately, followed by severe difficulty putting weight through the joint. Some might hear a pop or snap during the injury and feel like the joint is very loose or unstable.
Often times, the joint is immobilized and they send you for an x-ray to rule out a fracture. Then they will send you for an MRI to confirm the ligament tear.
Depending on the severity of the tear will determine whether or not you need surgery. I personally sprained my MCL during high school soccer (any sprain is technically a tear). I was on crutches for about a week and was unable to participate in sports for about two and half months while I rehabbed. Then I was given a knee brace to play in for the remaining basketball season. I fortunately did not need surgery.
