I had right lateral epicondylar release/tendon repair 4 months ago. a p.t. asked which tendon did u get repaired? how many tendons on the outer elbow?

ECRB: Lateral epicondylitis( "tennis elbow")surgery involves surgical debridement (open or arthroscopic ) of the extensor carpi radialis brevis(ecrb) tendon origin.Degenerative tendon here often has a 'fish flesh' appearance.Surgeons often 'drill' small holes in the lat.Epicondyle after debridement . Other tendons here: ecrl, epl, edc tendons(abbreviations).
