The condition characterized by painful inflammation of the tendon at the outer border of the elbow is commonly known as Tennis Elbow. This condition, also medically referred to as lateral epicondylitis, occurs when there is overuse or strain on the tendons that attach to the lateral epicondyle, the bony exterior part of the elbow. This inflammation can result from repetitive movements, usually involving wrist extension or gripping activities, making it prevalent among athletes, particularly tennis players, as well as individuals engaged in occupations requiring repetitive hand or arm use.

In contrast, Golfer's Elbow refers to similar inflammation but occurs on the inner side of the elbow (medial epicondyle), which distinguishes it from Tennis Elbow. Rheumatoid Arthritis and Osteoarthritis are both forms of arthritis that affect joints more broadly and involve inflammation of the joint itself rather than specific tendon issues. Therefore, understanding the specific location and nature of the inflammation is key to identifying Tennis Elbow accurately.
