What should you know about medial sprain?

Ligaments connect bones and help guide joint movement. A force that twists, bends, or loads a joint beyond its usual range can strain a ligament on its medial side. Mild injury may cause local tenderness and swelling; a more substantial injury can bring bruising, reduced movement, or a sense that the joint is unstable. The exact ligament depends on the joint involved, such as the inner knee or inner ankle. Pain alone cannot show how much tissue is affected. Examination of movement, tenderness, strength, and stability helps determine whether a fracture or a more serious injury also needs consideration.

Protect the joint from the movement that caused the injury and avoid sport while walking or basic movement remains painful. Elevation and a wrapped cold pack may help swelling; place a cloth between cold and skin. A splint may be useful when protection or support is needed, but it should fit correctly and be used according to clinical advice. As pain and swelling settle, physiotherapy can restore movement, strength, balance, and confidence before a gradual return to activity. Kinesiology taping may provide supportive feedback for some people, but it does not replace assessment or rehabilitation.

Get prompt medical attention if the joint looks deformed, you heard a pop followed by marked instability, or you cannot bear weight or use the limb normally. Rapid swelling, severe bruising, numbness, a pale or cold hand or foot, or pain after a major impact also warrants urgent review. Arrange routine care when pain, swelling, or looseness does not steadily improve, because a ligament injury may need targeted protection and rehabilitation.

Which ligament and joint are affected? Is the joint stable? Do I need an X-ray or another assessment? Should I use a splint, tape, or support? When can I begin strengthening, and what must I be able to do before returning to sport?
