So I'd love to know what the difference is between tendinopathy, a partial tear and a full tear.

Yeah.

So a partial tear can be less than one centimeter to three centimeters in width.

A full thickness tear is three to five centimeters.

Some people hear full thickness and think, oh gosh, it's completely ruptured.

That's not a ruptured tendon.

Above a five centimeter tear, you can have a massive tear, which is six plus centimeters.

So before we leave you, Stefan, what are the biggest mistakes you see people make when trying to fix their shoulder?
