The Medial Collateral Ligament goes from the inside of the upper shin bone (Tibia) to the inside of the bottom of the thigh bone (Femur). The Medial Collateral Ligament keeps your shin bone stable. Injury to this ligament can be a stretch, partial tear or complete tear.
There are three grades of Medial Collateral Ligament Injury:
- Grade 1 Injury — Incomplete tear of the ligament with mild symptoms
- Grade 2 Injury — Incomplete tear with instability and moderate symptoms
- Grade 3 Injury — Complete tear with instability and severe symptoms; other ligaments in the knee may also be torn
