INJURY

Knee Ligamentous Sprain (ACL, MCL, LCL) (noun): A sprain is the stretch or partial tear of ligaments which connect two bones. A knee sprain happens when the ligaments that support the knee get overly stretched, or torn, due to external or internal factors.

SIGN & SYMPTOMS

Based on how much damage is done to the ligament, the three grades of knee sprains are:
 
MILD – Mild pain & disability. Slight point tenderness, minimal laxity & swelling.
 
MODERATE – Hearing and/or feeling a pop or snap. Moderate pain & disability, swelling, point tenderness, joint laxity & discoloration.
 
SEVERE - Hearing and/or feeling a pop or snap followed by severe pain usually indicative of a complete tear. Excessive swelling, joint laxity & discoloration, unable to bear weight.
