What should you know about a moderate MCL sprain?

The medial collateral ligament runs along the inside of the knee and helps resist forces that push the knee inward. A moderate sprain means some fibres are damaged, while the ligament may still provide part of its support. Pain and tenderness commonly sit along the inner joint line, with swelling, stiffness, or a feeling that the knee is less steady during turning.

A clinician may examine the knee in different positions and use imaging when another injury, such as a fracture or cartilage problem, needs checking. The amount of instability and your ability to walk help guide the plan.

Protect the knee from twisting and impact at first. Use ice wrapped in cloth for short periods if it eases discomfort, elevate the leg for swelling, and use crutches only as instructed. A brace or [Splinting] approach may be recommended to limit unwanted movement. As pain settles, guided exercises restore knee motion, thigh strength, balance, and confidence; [Physiotherapy] can structure this progression. [Kinesiology Taping] may be discussed as an added support, not a replacement for assessment or exercise.

Get prompt assessment if you cannot bear weight, the knee looks deformed, swelling appears rapidly, the foot becomes numb or cold, or the knee repeatedly gives way. Arrange review if pain, stiffness, or instability is not improving with the prescribed plan, or if a new locking sensation develops.

Ask whether the ligament feels stable, how much weight and bending are appropriate, whether a brace is needed, and which exercises can start now. Ask when driving, work, sport, and direction-changing movements can be resumed safely.
