What is Knee Swelling? 

Knee swelling is a sign that means there is accumulation of fluid in or around your knee joint. 

The knee is a complex joint formed by the femur (thigh bone), tibia (shin bone), and patella (kneecap). It is considered as the biggest joint in the body. Further your knees are also containing cartilage, muscles, ligaments and nerves. 

Anything that irritates and creates difficulties for your knees can cause swelling. In case you injured your knee or have a medical condition that is damaging the tissue around it, your knee can get swelling. 

You might face other symptoms in case you have a swollen knee involving: 

• Stiffness  
• A feeling of heat or warmth 
• Knee pain 

Common Causes of Knee Swelling 

Doctors categorise knee swelling as traumatic or nontraumatic. Traumatic knee swelling generally reflects you’ve experienced an injury. Injuries due to sports are the most frequent cause of knee swelling, including: 

• ACL tears 
• Meniscus tears 
• Sprains 
• Bone Fractures 
• Dislocations 
• MCL tears 
• Hyperextended knees 
    

Nontraumatic knee swelling is generally caused by arthritis. Further, degenerative arthritis and inflammatory arthritis can cause swelling. 

Other health conditions that can cause nontraumatic knee swelling involving: 

• Tendinitis 
• Bursitis 
• Infections 
• Autoimmune disorders
