Exercise is medicine. It promotes health and can be instrumental in the treatment of chronic disease. Current knowledge suggests that exercise carried out within the limits of normal joint motion and comfort does not predispose to osteoarthritis. In fact, normal repetitive loading to a joint is essential for its physiologic function. Sports that subject joints to intermittent high or violent impact loads may increase the risk of subsequent osteoarthritis, but well-designed studies are lacking and this association is at best speculative. There is clear evidence, however, that joints with preexisting injury, particularly if there is biomechanical alteration, are at increased risk of developing osteoarthritis with repetitive loading. Finally, patients with arthritis can derive a number of benefits from a thoughtful and closely monitored exercise program.
运动是良药。它促进健康，并且在慢性病治疗中可能起重要作用。目前的知识表明，在正常关节活动和舒适度范围内进行的运动不会导致骨关节炎。事实上，对关节进行正常的重复性负荷对其生理功能至关重要。使关节承受间歇性高冲击或暴力冲击负荷的运动可能会增加后续患骨关节炎的风险，但缺乏精心设计的研究，这种关联充其量只是推测性的。然而，有明确证据表明，已有损伤的关节，特别是存在生物力学改变的关节，在重复性负荷下患骨关节炎的风险会增加。最后，关节炎患者可以从精心设计且密切监测的运动计划中获得诸多益处。
