Causes of Knee Swelling
Knee swelling, or effusion, can be caused by a variety of conditions. According to an article published in the May 2019 issue of the journal Pain Research and Management, it is the most common symptom of knee arthritis. You might also experience knee swelling right after an injury to your joint.
To prevent worsening of your condition, see your doctor for a diagnosis of the cause of your swelling before attempting exercises for fluid on the knee. Another option is to seek physiotherapy treatment for knee effusion.
Exercises for Water on the Knee
Range-of-motion exercises and gentle strengthening can improve your function, according to Kaiser Permanente. Exercises should not increase your knee pain — or your swelling. If either of these occur, stop exercising and contact your doctor, advises the American Academy of Orthopaedic Surgeons.
