📋Overview
Tendinitis, also spelled tendonitis, is the inflammation or irritation of a tendon, the thick fibrous cords that attach muscle to bone. It is a common condition often caused by repetitive motion or overuse. The term 'tendinitis' is sometimes used interchangeably with 'tendinopathy,' though tendinopathy refers more broadly to tendon disorders including degeneration without inflammation. Modern terminology favors 'tendinopathy' for chronic cases, while 'tendinitis' refers to acute inflammation.
