Tendinopathy is a general term that describes tendon degeneration characterized by a combination of pain, swelling, and impaired performance.
Common sites include the rotator cuff (supraspinatus tendon), wrist extensors (lateral epicondyle) and pronators (medial epicondyle), patellar and quadriceps tendons, and Achilles tendon.
The exact etiology is unclear. Studies suggest it is an overuse condition leading to inadequate tendon repair that predisposes the tendon to microtears and degeneration.
Treatment consists of activity modification, relative rest, ice, stretching, and strengthening. Stretching and strengthening are best guided by a physical therapist.
Those who do not improve with conservative therapy should seek surgical evaluation.
