Exercise strengthens muscles and stronger muscles provide better support to joints. By strengthening the muscles surrounding the knee, including the quadriceps and hamstring muscles, the knee becomes more stable and bones are more protected from impact, which in turn reduces pain.
Exercise also releases endorphins, the body’s natural pain killers.
Increases range of motion and function.
Pain can discourage a person from being active, thus compounding the problem of joint pain with stiffness, which leads to increased pain. Regular exercise will help keep the knee joint and surrounding muscles remain limber, thereby increasing knee function.
Supports healthy cartilage.
Joint cartilage needs motion and a healthy amount of stress to stay healthy.
Synovial fluid is stored in cartilage like water in a sponge. When the joint is used, the synovial fluid comes out from the cartilage and lubricates the joint .
It also reduces inflammation and supports healthy joint function
Helps with weight loss.
Exercise combined with a nutritious, low fat diet can help in weight loss .
So putting less pressure on the knee joint. The effect of weight loss has an amplified benefit:
even losing 5 kg means 20 % less pressure on the knee with each step.
Helps maintain function.
Chronic knee pain can prevent a person from doing activities of daily living or participating in sports and recreational activities.
It’s frustrating and sometimes depressing.
Exercise , proper diet , medication, and activity modifications can help in longer life for the joints and avoid joint replacement surgery.
