Knee sprain with inability to fully flex?
Hello, Doctor: I sustained a knee sprain a month ago, and the examination revealed an injury to the medial collateral ligament.
I can walk and bend my knee now, and there is no swelling or pain, but I am unable to fully bend it.
When I attempt to bend it, I feel tightness and a bit of pain, and I experience some soreness when I try to straighten it forcefully.
Is this normal? I am worried that I might not be able to fully bend my knee in the future.

Ligament injuries typically take about one to two months to heal, so the current situation is still considered normal.
Gradual bending is possible, and full recovery can ultimately be achieved.

Hello! It's great to hear that you're making progress after your knee sprain, particularly with your ability to walk and bend your knee without significant pain or swelling. However, I understand your concerns about the limited flexibility and the tightness you feel when trying to fully bend your knee.
When it comes to a sprain of the medial collateral ligament (MCL), which is what you've described, it's common to experience some residual tightness and discomfort during the recovery process. The MCL is crucial for stabilizing the knee, and injuries to this ligament can lead to changes in how the knee functions, especially during movements that require bending or twisting.
1. Tightness and Pain: The tightness you feel when bending your knee could be due to a few factors. After an injury, the surrounding muscles and connective tissues may become stiff as a protective response. Additionally, scar tissue can form during the healing process, which may restrict your range of motion. The slight pain or discomfort when extending your knee could also be a sign that the muscles around the knee are still recovering and may need more time to regain their full strength and flexibility.
2. Normal Recovery: It is quite normal to experience some limitations in range of motion after an MCL injury. Many patients report similar feelings of tightness and discomfort during the early stages of recovery. The fact that you can walk and bend your knee without significant pain is a positive sign. However, it’s essential to continue with rehabilitation exercises to improve flexibility and strength.
3. Rehabilitation Exercises: Engaging in a structured rehabilitation program is crucial. Focus on gentle stretching and strengthening exercises for the quadriceps, hamstrings, and calf muscles. Exercises like heel slides, straight leg raises, and gentle squats can help improve your knee's flexibility and strength. If you haven't already, consider working with a physical therapist who can provide personalized guidance and ensure that you're performing exercises correctly.
4. Gradual Progress: Recovery from an MCL injury can take time, and it's important to be patient with yourself. Many individuals find that their range of motion improves significantly over several weeks to months as they continue to rehabilitate the knee. It’s not uncommon for full range of motion to return gradually, especially if you stay consistent with your exercises.
5. Future Concerns: Your concern about not being able to fully bend your knee in the future is understandable. However, with proper rehabilitation, most people can regain their full range of motion. If you continue to experience tightness or pain, it may be beneficial to consult with your healthcare provider or a physical therapist for further evaluation. They can assess your knee's condition and recommend additional treatments, such as manual therapy or modalities to help alleviate tightness.
In summary, while it’s normal to experience some tightness and discomfort after an MCL injury, continuing with rehabilitation exercises and being patient with your recovery process will likely lead to improvements. If you have any ongoing concerns or if your symptoms worsen, don’t hesitate to reach out to your healthcare provider for further evaluation. Wishing you a smooth and successful recovery!
