Knee swelling: If the swelling is confined to your knees, it’s likely that you have what we call a joint “effusion” which, with 76y/o knees, is likely to be due to osteoarthritis (wear and tear). Sometimes, osteoarthritis can cause inflammation around the joint leading to swelling. Unfortunately, this will not improve with your water tablets. You should keep active, elevate your legs & consider physiotherapy.

Water pills not work: Water pills do not work for this type of water. It is built up inside of the knee and is a knee problem. Even if you have the water in the knee which we Call an infusion. It can be due to underlying arthritis and we could also see it in previous surgery

Knee: Water on the knee or knees is usually caused by irritation to knees. Being overweight is a risk factor for arthritis. Decrease your weight and knee problems will likely improve.
