Knee pain can be caused by a variety of joint issues. It often stems from the wear and tear of the joint surfaces, leading to discomfort and stiffness. Overuse or repetitive activities can strain the tendons and ligaments around the knee, causing inflammation and pain. Injuries from sudden movements, twists, or impacts may damage the cartilage or soft tissues within the knee, leading to instability and swelling. Physiotherapy can address each of these problems to relieve pain, restore strength, and enhance joint function.
