How to treat knee synovitis with fluid accumulation

For knee synovitis with fluid accumulation, the first step is to reduce the load on the knee joint and avoid strenuous exercise, while performing isometric exercises to promote absorption of intra-articular fluid. When the amount of joint fluid is small, ultra-short wave therapy can be used to eliminate joint inflammation and relieve fluid accumulation. In elderly patients with a large amount of joint fluid, joint aspiration may be necessary to remove the accumulated fluid, followed by intra-articular injection for closure.
