PATHOLOGY

Detailed explanation-1: -Tennis elbow is inflammation or, in some cases, microtearing of the tendons that join the forearm muscles on the outside of the elbow. The forearm muscles and tendons become damaged from overuse-repeating the same motions again and again. This leads to pain and tenderness on the outside of the elbow.

Detailed explanation-2: -The cause is repeated contraction of the forearm muscles that you use to straighten and raise your hand and wrist. The repeated motions and stress to the tissue may result in a series of tiny tears in the tendons that attach the forearm muscles to the bony prominence at the outside of your elbow.

Detailed explanation-3: -It most often occurs as the result of an injury-typically, an elbow dislocation. This type of injury can damage the bone and ligaments that surround the elbow joint. When the elbow is loose and repeatedly feels as if it might slip out of place, it is called recurrent or chronic elbow instability.
