Not every rotator cuff tear needs surgery — but some do, and knowing the difference early saves time, money, and shoulder function.

The rotator cuff is where orthobiologic medicine and surgical judgment meet most directly, and it''s where I spend a lot of time helping patients sort out which path is actually right for them.

## The spectrum of tears

"Rotator cuff tear" covers an enormous range: partial-thickness fraying that behaves more like tendinopathy, small full-thickness tears in lower-demand patients, and large chronic tears where the tendon has retracted and the muscle has begun to atrophy and turn to fat. These are different problems with different answers.

## Where orthobiologics fit

For partial-thickness tears and tendinopathy — especially when pain, rather than weakness, is the main complaint — PRP and related treatments have a reasonable and growing evidence base. The goal is to improve the tendon environment, reduce pain, and create a window for the strengthening work that ultimately restores function. Many patients in this category avoid surgery entirely.

## Where surgery is the honest answer

Here is where I''ll be direct, because it''s what I''d tell my own family: a large, full-thickness tear with retraction — particularly in an active person — is a surgical problem. Biology has limits, and no injection reattaches a tendon that has pulled away and scarred back. Worse, time matters: chronic tears undergo muscle atrophy and fatty infiltration that can make a later repair less successful or even impossible. Waiting a year on repeated injections for a tear that needed repair is not conservative care; it''s lost opportunity.

## How we decide

The decision weighs tear size and chronicity on MRI, your strength and function on exam, your age and activity demands, and your response to a genuine trial of non-operative care — not a single cortisone shot, but structured rehabilitation with or without biologic support.

If you''ve been told you have a cuff tear and aren''t sure which category you''re in, that''s exactly the question a consultation answers.
