Elbow arthritis is a condition that occurs when the cartilage in the elbow joint wears down, leading to pain, stiffness, and swelling. This can result from age, injury, or repetitive use. The most common types of elbow arthritis are osteoarthritis and rheumatoid arthritis, each affecting the joint differently. Symptoms of elbow arthritis may include difficulty bending or straightening the arm, tenderness around the joint, and a reduced range of motion. Treatment options often involve physical therapy, medications for pain relief, and in severe cases, surgery to repair or replace the damaged joint.
