Arthritis or another medical condition could be the cause of a stiff knee. Overuse of the joints and muscles in your knee can also cause stiffness. Strengthening your hamstrings, quadriceps and other knee-supporting muscles protects your knees from stress and the shock of impact, according to American Academy of Orthopaedic Surgeons. Stretching your muscles improves flexibility, which can prevent stiffness and injury.
Mild knee swelling due to an injury or previously diagnosed condition may not require medical attention. 1  Instead: 2  Rest. Try not to walk or put weight on the leg. 3  Ice. Place ice in a plastic bag, wrap it in a towel, and apply if to the knee for 15 to 20 minutes every two to four hours. 4  Elevate. When sitting, elevate your knee above your waist.
