You Knee consists of 4 ligaments:
The 4 ligaments that hold the knee together are known as the ACL, MCL, LCL and PCL.
- ACL (Anterior-Cruciate Ligament) is the main ligament inside the knee that is torn when an athlete’s knee is injured. A complete ACL tear requires surgery and will take 6 to 12 months of physical therapy. Normally, the athlete can return after 9 months depending on the athletes conditioning and recovery.
- MCL( medial collateral ligament) is the ligament located on the inner side of your knee. It is common to sprain the MCL or to tear it at the same time with an ACL tear when pivoting and over-rotating. If it’s just an MCL tear, recovery time can rage from 3 to 4 months.
- LCL( lateral collateral ligament) is the ligament located on the outer side of your knee, which is used to stabilize side to side movements. LCL injury is normally associated with a direct blow and isn’t as common as an MCL or ACL tear.
- PCL( posterior collateral ligament) is the ligament inside the knee which prevents the tibia from moving to the rear. Injury to the PCL is normally associated with direct blows and aren’t as common as the MCL and ACL tears.
