Fluid on the Knee: Causes and Treatment

What Is Fluid on the Knee?
Fluid on the knee is an accumulation of fluid in the knee joint and capsule. This fluid can be caused by a variety of factors, and when it accumulates it can lead to pain, swelling, and decreased range of motion. In some cases, fluid on the knee can be a sign of a more serious problem, so it is important to understand why it is happening and what can be done to address the issue.

Causes of Fluid on the Knee
There are a variety of causes of fluid on the knee. These include trauma, infection, arthritis, overuse injuries, certain medications, and certain medical conditions.

Trauma: Traumatic injury can cause the knee joint to swell and accumulate fluid. This can occur due to a direct blow to the knee, a fall, or an overuse injury.

Infection: Infections of the knee joint can cause the body to respond by creating an inflammatory response in the joint. This can lead to an accumulation of fluid in the knee joint.

Arthritis: Arthritis can cause fluid on the knee due to an inflammatory response in the joint. This can lead to weakness, pain, and swelling in the joint, which can limit range of motion and cause fluid to accumulate.

Overuse: Overuse injuries can cause the joint to become inflamed and can lead to the accumulation of fluid. These injuries are common in athletes who train heavily and repetitively and can often be prevented through proper conditioning and rest.

Medications: Certain medications, such as steroids and certain anti-inflammatory medications, can cause an increase in the amount of fluid that is retained in the joint.

Medical Conditions: Certain medical conditions, such as kidney disease or heart disease, can cause fluid retention that can lead to fluid accumulating in the knee joint.

Treatment for Fluid on the Knee
Fluid on the knee can be treated with rest, ice, and compression. Over-the-counter pain relievers can also be taken to help reduce pain and inflammation. In more serious cases, physical therapy, cortisone injections, and surgery may be necessary. It is important to consult with a doctor to determine the best course of action.

When fluid on the knee is caused by an underlying medical condition, that condition should be treated according to the doctor’s instructions. Treating the underlying condition can help to reduce the amount of fluid in the knee joint and help to reduce the swelling and discomfort associated with it.
