From the Guidelines
For a medial collateral ligament (MCL) injury, the next step should be RICE therapy (Rest, Ice, Compression, Elevation) for the first 48-72 hours, followed by a gradual rehabilitation program. The provided evidence does not directly address MCL injuries, but general principles of ligament injury management can be applied. Resting the knee by avoiding activities that cause pain, applying ice for 15-20 minutes every 2-3 hours, using a compression bandage or knee brace to provide support, and elevating the leg when possible can help manage pain and reduce inflammation 1.
Key Considerations
- Over-the-counter pain medications like ibuprofen (400-600mg every 6-8 hours with food) or acetaminophen (500-1000mg every 6 hours) can help manage pain and reduce inflammation.
- For moderate to severe MCL injuries, a hinged knee brace should be worn for 2-6 weeks depending on injury severity.
- Physical therapy focusing on range of motion exercises and progressive strengthening should begin once acute pain subsides, typically within 1-2 weeks.
- Most MCL injuries heal without surgery in 2-8 weeks depending on severity.
- Surgery is rarely needed except for complete tears with instability or when other knee structures are damaged, as noted in the context of other ligament injuries 1.
Rehabilitation and Prevention
The use of knee braces, including prophylactic and functional braces, has been studied, but their benefits in preventing MCL injuries are not conclusively established 1. The focus should remain on proper rehabilitation techniques and gradual return to activity to minimize the risk of further injury.
Given the lack of direct evidence on MCL injuries in the provided studies, the approach should prioritize conservative management and rehabilitation, reserving surgery for cases with significant instability or complications, similar to the principles outlined for other ligament injuries 1.

MCL Injury Next Steps
The next steps for a medial collateral ligament (MCL) injury depend on the severity of the injury.
- For minor injuries, treatment can often be conservative with early rehabilitation 2.
- For more significant tears, surgery may be necessary 2.
- The gold standard for diagnosis is MRI, which can help determine the severity of the injury and guide treatment decisions 2.
- In some cases, autologous platelet-rich plasma (PRP) therapy may be effective for refractory pain after low-grade MCL injury 3.
- For combined anterior cruciate ligament (ACL) and MCL injuries, the best approach is not clear, but reconstruction of the combined injury in a delayed fashion may facilitate return of range of motion and allow time for low-grade MCL tears to heal 4.
Treatment Options
Treatment options for MCL injuries include:
- Nonoperative management, which may be suitable for lower-grade injuries 4
- Repair or reconstruction of the MCL, which may be necessary for more significant tears or combined ACL-MCL injuries 4
- Autologous PRP therapy, which may be effective for refractory pain after low-grade MCL injury 3
- Analgesic agents, such as piroxicam, which may improve ligament healing 5
