Tendonitis vs Tendonosis: What You NEED to Know! #shorts

In this short educational video, Christopher Ellis clarifies common tendon pathology terminology. He defines tendinopathy as a generic, non‑specific label for any tendon disease, noting it is essentially a placeholder term. He then breaks down tendinitis, explaining that the suffix “‑itis” denotes inflammation, making tendinitis an acute, inflammatory condition often triggered by a sudden increase in activity (e.g., a runner’s Achilles pain after adding mileage). Finally, he describes tendinosis as a chronic, degenerative state characterized by fiber fraying and disorganization within the tendon, distinguishing it from the acute inflammation of tendinitis. The video’s purpose is to help viewers quickly differentiate these terms and understand their clinical relevance.
