The knee ligaments help to keep the knee stable during movement. Ligament injuries to the knee include anterior cruciate ligament injuries (ACL), posterior cruciate ligament injuries (PCL), and medial collateral ligament injuries (MCL).
Located on either side of the knee joint, the medial collateral and lateral collateral ligaments control how much the knee moves from side to side. It is possible to sprain or tear the medial collateral ligament by twisting your leg while it’s straightened, such as when skiing or playing football; this can also cause damage to the lateral collateral ligament.
The anterior cruciate ligament and posterior cruciate ligament help keep the knee stable when the joint is moving backwards and forwards. Damage to the anterior cruciate ligament is among the most serious types of knee injury.
Treatment can include one or more of the following:
- Ice treatment
- Anti-inflammatory medication
- Knee brace
