How should I explain to a patient the MRI findings of mild common flexor tendinosis with low‑grade partial‑thickness tearing at the origin, mild common extensor tendinosis, and an intermediate‑grade partial‑thickness tear of the triceps insertion measuring 8 mm on a background of moderate tendinosis?

Explaining Elbow MRI Findings to Your Patient

Your MRI shows wear-and-tear damage to three tendons around your elbow—the flexor tendons on the inside, extensor tendons on the outside, and the triceps tendon in the back—with small tears in the flexor and triceps tendons that can heal with proper treatment.

Breaking Down the Findings in Plain Language

What "Tendinosis" Means

  • Tendinosis is degenerative tendon damage from overuse and failed healing, not inflammation—think of it like fraying of a rope from repetitive stress 1
  • This represents unhealthy tendon tissue that produces pain and requires rehabilitation to revitalize 1
  • The condition develops insidiously with load-related pain that may initially improve with warm-up but progressively worsens 2

The Specific Tendon Problems

Inside of the elbow (flexor side):

  • Mild tendinosis with a low-grade partial tear at the origin—this is a small tear affecting only part of the tendon thickness 2
  • This typically responds well to conservative treatment 2

Outside of the elbow (extensor side):

  • Mild tendinosis without significant tearing 2
  • This is the classic "tennis elbow" pattern affecting the extensor carpi radialis brevis-extensor digitorum communis complex 1

Back of the elbow (triceps):

  • Moderate tendinosis (more advanced wear-and-tear) with an intermediate-grade partial tear measuring 8mm 2
  • This represents a more substantial injury but still involves only part of the tendon thickness 3

What This Means for Treatment

Initial Management Strategy

The cornerstone of your treatment should be progressive eccentric strengthening exercises, which are the most effective treatment for tendinopathy and may actually reverse the degenerative changes 2

  • Start with relative rest and activity modification—reduce repetitive loading activities that reproduce your pain 2
  • Avoid overhead motions and repetitive flexion-supination movements 2
  • Begin a structured rehabilitation program focused on eccentric strengthening 2

Additional Treatment Options

  • Local corticosteroid injection provides better acute-phase pain relief than oral NSAIDs, though it doesn't change long-term outcomes 2
  • If you notice muscle atrophy (shrinkage), this indicates the condition has been present longer than you may realize 2

When to Consider Surgery

  • Surgery becomes an option only if rehabilitation fails after an appropriate trial of conservative treatment 1
  • The presence of partial tears does not automatically require surgery—most respond to proper rehabilitation 2

Important Caveats

  • If you have multiple symptomatic tendons on both sides of your body, you should be evaluated for rheumatic disease 2
  • MRI was the appropriate imaging choice with 92.4% sensitivity and 100% specificity for detecting these types of tendon injuries 2
  • The quality of your rehabilitation program matters more than the specific imaging findings for predicting your outcome 2
