The knee joint contains 4 main ligaments that provide support and stability to the knee, and limit its movement. One of the ligaments is the MCL, located towards the inside of the knee. The MCL is one of the strongest ligaments in the body. An MCL sprain describes the partial to complete disruption of the MCL.
Risk factors include:
- Participation in contact, and twisting sports
- Pre-existing instability
Mild to moderate sprains are often healed in 2-8 weeks with conservative treatment that includes knee bracing, usage of crutches, cross fiber friction massages, and other treatment techniques.
