If youΓÇÖve noticed a golf ball-sized lump on the outside of your knee, itΓÇÖs important to seek medical attention as soon as possible. While it may be harmless, there are several potential causes that could require treatment. In this article, weΓÇÖll explore the possible causes, signs, and symptoms of a golf ball-sized lump on the outside of the knee, as well as treatment options and preventative measures.
Possible Causes of Golf Ball Sized Lump on Outside of Knee

Injuries and Traumas to the Knee
One possible cause of a golf ball-sized lump on the outside of the knee is an injury or trauma to the knee joint. This can include a sprain, strain, or tear of the ligaments or tendons in the knee, or a fracture of the knee bone. In some cases, the injury may result in the formation of a cyst or fluid-filled sac in the knee joint, which can cause swelling and pain.
Cysts or Fluid-Filled Sacs
Another potential cause of a golf ball-sized lump on the outside of the knee is a cyst or fluid-filled sac. There are several types of cysts that can form in the knee joint, including a BakerΓÇÖs cyst, which is a bulge that forms behind the knee, or a ganglion cyst, which is a non-cancerous growth that can develop on the tendon sheaths in the knee.
Cysts can often be treated through conservative methods such as rest, ice, and compression, but more severe cases may require surgical intervention.

Signs and Symptoms of a Golf Ball Sized Lump on Outside of Knee

The presence of a golf ball-sized lump on the outside of the knee is a clear sign that something is amiss, but there are several other symptoms that can accompany this condition. Some common signs and symptoms include:
Pain or Tenderness in the Affected Area
Pain or tenderness is often the first sign of a problem in the knee joint. This can be felt as a dull ache or a sharp, stabbing pain, depending on the severity of the condition.
Swelling or Inflammation
Inflammation and swelling can occur in response to an injury, infection, or other condition affecting the knee joint. This can cause the knee to feel stiff, tight, or uncomfortable.
Limited Range of Motion or Stiffness
If you have a golf ball-sized lump on the outside of your knee, you may find it difficult to move your knee joint as freely as you normally would. This can be due to the presence of the lump itself or as a result of other factors such as inflammation or pain.
Redness or Warmth
Inflammation and swelling can cause the skin around the knee joint to become red and warm to the touch. This is a sign that the body is sending blood to the affected area in an attempt to promote healing.
Diagnosis and Treatment of Golf Ball Sized Lump on Outside of Knee

If youΓÇÖre experiencing any of the above symptoms or have noticed a golf ball-sized lump on the outside of your knee, itΓÇÖs important to seek medical attention as soon as possible. Your doctor will perform a physical examination of your knee and may order imaging tests such as X-rays, MRIs, or CT scans to determine the cause of your symptoms.
Once a diagnosis has been made, your doctor will work with you to develop a treatment plan that addresses the underlying cause of your symptoms. Treatment options may include:
Physical Therapy
Physical therapy can be an effective treatment option for many types of knee injuries and conditions. This can include exercises and stretches designed to strengthen the muscles and improve flexibility in the knee joint.
Medications
Your doctor may prescribe pain medications, anti-inflammatory drugs, or other medications to help manage your symptoms and promote healing.
Surgery
In some cases, surgery may be necessary to remove the golf ball-sized lump or address the underlying cause of your symptoms. This can include procedures such as arthroscopy, which involves using a small camera and instruments to view and repair damage within the knee joint.
