Knee joint hyperplasia is not curable because it is a manifestation of aging. All joints age at a certain age, but due to different environments, different methods of use, different exercises, and different medical interventions, joint aging can be delayed and hyperplasia can appear later. Once the joint has developed hyperplasia, if the correct countermeasures are used, such as choosing the right sport, active medical intervention and appropriate sports, the correct use of the joint will slow down the rate of aging and the rate of hyperplasia. Some sports have an effect on the knee joint, such as walking. Patients with signs of knee degeneration or with knee osteoarthritis are not suitable for long strenuous walks and can choose suitable sports. For example, swimming is a zero-weight-bearing exercise that does not put any pressure on the joints. In addition, bicycling, because when riding a bicycle, the weight is added to the seat, not completely added to the knee joint, the knee joint belongs to the semi-weight-bearing state, will slow down the joint degeneration, will not aggravate the joint damage. But other sports, such as running, brisk walking, playing table tennis, badminton and other sports, are not suitable for arthritis patients to participate in, because these sports can cause joint damage.
