what does a sprained knee feel like
A knee ligament sprain occurs when there is damage to one of these ligaments. The role of ligaments is to limit the amount of mobility of a joint, or prevent certain movements altogether.They allow the knee to function as an effective hinge of the thigh bone (femur) on the shin bones (tibia and fibula).ith a moderate (grade 2) sprain, the ligament tears partially. This is the situation where there is usually quite a bit of pain at the time of injury, and moderate instability â the patient will complain of the leg âgiving wayâ. Swelling and bruising are common, and use of the joint is usually painful and difficult.
