The Lateral Collateral Ligament is the main supporting ligament on the outside of the knee. The ligament provides stability to the joint when the knee is pushed outward. A Lateral Collateral Ligament Injury involves stretching or tearing of this ligament.
There are 3 degrees of Lateral Collateral Ligament Injury:
- First-Degree Injury — Mild stretching of the ligament with no looseness
- Second-Degree Injury — Partial tear of the ligament
- Third-Degree Injury — The ligament is completely torn and the joint is unstable
