Medial collateral injuries usually occur during a valgus force to the knee especially during contact sport (e.g. a tackle from the side). You will be examined to exclude any other associated injuries. Your treatment will be determined by the grade of your injury.
Isolated grade I, II and III injuries that are stable in extension, without any other ligamentous injuries, are treated conservatively.
- RICE â€’ rest, ice, compression and elevation
- Rehabilitation: quadriceps rehabilitation and straight leg raises immediately, cycling or resistance exercises when tolerated; thigh adduction exercises.
Surgery is considered for grade III injuries that present as follows:
- Isolated with unstable despite rehabilitation
- Valgus laxity in full extension
- Associated with ACL/PCL injuries
- Chronic valgus instability.
Surgery can either be a MCL repair or reconstruction depending on the time span of the injury.
You will be in a brace for 6 weeks whether you are operated on or not.
