Grade 1 MCL Rehab Program
If you have a grade 1 MCL sprain, you may have mild tenderness on the inside of the knee over the ligament. Usually, there is little or no swelling. The rehabilitation protocol for a mild medial ligament sprain can be split into 4 phases:
- Phase 1 begins immediately following injury and usually lasts 1 week. The aim is to reduce swelling and ensure your knee can be straightened fully and bent to more than 90 degrees pain-free.
- Phase 2 begins after 1 week. The aims are to eliminate swelling, regain full range of movement and return to slow jogging.
- Phase 3 usually begins after 2 weeks. The aims are to maintain a full range of motion, equal strength of both legs, return to running and some sports -specific training.
- Phase 4 usually begins after 4 weeks and lasts 3 to 6 weeks. The aim is to return to full sports specific training and competition.
Grade 2 or 3 Sprain
For grade 2 and particularly grade 3 MCL sprains, it is important that the ends of the ligament are protected and left to heal without continually being disrupted. The rehabilitation guidelines for a grade 2+ or 3 medial ligament sprain (more severe) are separated into 4 phases:
- Phase 1 begins immediately following injury and may last 4 weeks. The aims are to control swelling, maintain the ability to straighten the leg bend the knee to more than 90 degrees, begin strengthening exercises.
- Phase 2 usually begins after 4 weeks and lasts for 2 weeks. The aims are to eliminate swelling, full weight bearing on the injured knee, full range of motion, injured leg almost as strong as the good one.
- Phase 3 begins after week 6 and lasts for a further 4 weeks. The aims are to regain full range of motion, strength, return to light jogging and by week 10 from injury, return to sports specific exercises.
- Phase 4 usually begins 10 weeks following injury and lasts for between 2 and 4 weeks. The aims are to return to full sports specific training and competition without a brace for support and regain full strength and mobility.
