Mild medial collateral ligament sprain

The MCL is a strong band on the inner knee that helps limit side-to-side movement. A mild injury can cause local soreness and tenderness after the ligament is stretched. Walking may be possible, although changing direction, kneeling, or turning may be uncomfortable. A clinician checks stability and considers whether another knee injury is also present.

For the early phase, avoid cutting, pivoting, and contact activity. Use comfortable walking, gentle knee bending, and cold therapy with a cloth barrier when these reduce symptoms. A knee brace can provide support for selected activities, while physiotherapy can restore knee motion, thigh strength, and balance. Progress only when everyday movement is becoming easier; a return-to-sport programme can then build running, direction changes, and sport-specific control in stages.

Seek care promptly if the knee cannot bear weight, becomes locked, looks deformed, or feels repeatedly unstable. Rapid swelling, severe pain, loss of sensation, or a foot that becomes unusually cold or pale also needs urgent attention. Arrange review when symptoms plateau or worsen instead of gradually settling, since the MCL may not be the only structure involved.

Ask how stable the ligament feels, whether you need a brace, and which exercises are suitable now. Request clear milestones for stairs, work, driving, running, and returning to your sport.
