Can I exercise if I have knee arthritis?

Knee arthritis usually causes joint pain and limited movement. Appropriate exercise can help strengthen the muscles around the joint, reduce the burden on the joint, and increase joint flexibility. Below are some recommendations: 1. Low-impact aerobic exercises: Such as swimming or cycling, these exercises place less stress on the joints and can improve cardiovascular health while reducing joint pain. 2. Strength training: Performing mild strength exercises targeting the thigh muscles (quadriceps and hamstrings) can help stabilize the knee joint and alleviate pain. 3. Flexibility exercises: Gentle stretching movements can increase the joint's range of motion, such as swinging the knee joint forwards and backwards. 4. Balance and coordination training: Activities such as yoga or tai chi can help improve body balance and reduce the risk of falls, thus protecting the knee joint. 5. Rest and ice application: Allow adequate rest for the joint after exercising, and apply ice as needed to reduce swelling and pain. If discomfort occurs, prompt medical attention is recommended.
