what helps knee stiffness
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.
