This controlled histopathologic study compared surgical specimens from 11 patients with chronic refractory lateral epicondylitis to 12 cadaveric controls. A blinded pathologist graded 15 microscopic features to define the true histologic character of the condition. The central question: is chronic lateral epicondylitis an inflammatory or a degenerative process?
When a patient has lateral elbow pain that fails NSAIDs and rest, remember this: the underlying tissue is degenerated, not inflamed. That reframing is the whole point of this paper. The surgical specimens showed vascular and fibroblastic proliferation with focal hyaline degeneration, but zero inflammatory cells or granulation tissue.
This is why the term 'tendinosis' is more accurate than 'tendinitis,' and why anti-inflammatory medication targets a process that is not actually present.
The study also flags a caution about corticosteroid: calcific debris appeared only in patients with multiple injections, and steroid-injected animal tendon shows the same hyaline degeneration. Repeated injections may worsen the tendon rather than heal it.
As a case-control study with a blinded pathologist and true controls, this design is stronger than the uncontrolled surgical case series that preceded it, giving real weight to the degenerative model of chronic epicondylitis.
