Hello Dear,
Knee joint effusion refers to accumulation of fluid in the
joint which is usually secondary to arthritic changes,traumatic
injuries,meniscus tears,ligament injuries.
The treatment consists of draining the fluid from knee to help relieve the pressure in the joint, thereby helping with symptoms. Sometimes small amount of cortisone is injected in the knee to help prevent the fluid from returning. Patients with severe arthritis may eventually require surgery to treat their condition.
