A ligament injury in the knee involves damage to the tough bands of tissue connecting the bones within the joint. This type of injury commonly occurs during sports activities or sudden twists of the knee. Symptoms often include pain, swelling, and instability. Treatment may range from rest, physical therapy, and bracing for mild injuries to surgical intervention for more severe cases. Adhering to the recommended treatment plan and rehabilitation exercises is essential for a successful recovery, ensuring that you regain strength and stability in the knee joint.
