Exercise is an excellent treatment for the pain associated with arthritic knees. Even though it seems contradictory, exercise extends the knee's range of motion and strengthens muscles surrounding the joint. Strong muscles help the knee to deal with shock, which lessens arthritis pain, says Healthline.
Some discomfort is normal during exercise, so even if the knee responds with mild pain during a workout, it is important to keep going, reports Healthline. Some stiffness and soreness the day after exercise are normal, as well, particularly if the person is normally sedentary. If the knee swells, or the patient experiences severe stiffness or pain, it is necessary to consult a doctor to find the right exercise plan.
People who have arthritis in the knee benefit from moderate exercise for at least 30 minutes per day, five days per week, notes Healthline. For those who find 30 minutes of continuous exercise to be challenging, it is acceptable to break it down into three sessions of 10 minutes each. Within a month patients are likely to notice increased mobility and decreased pain. Walking in sturdy shoes makes a good starting point for exercise. However, walking or jogging in water, in a pool's shallow end, boost knee flexibility and increase muscle strength with little impact to the knee because the water bears the weight.
