The Berrios and Francis situations are exactly what I said, conservative treatment first. There's a standard with which these things are dealt with. You do the imaging, you get the report interpreted by the experts and you do what they recommend first. Full tears of ligaments or detached muscles... yeah, you go to surgery because there's nothing conservative treatment can do in those scenarios. If there's no tear, or it's just a partial tear, conservative treatment is usually the go-to, in the form of platelet rich plasma injections and PT, and it works a decent amount of time.
Of course there's gray area. In the absence of full tears where the treatment/surgery course is obvious, there is nothing BUT gray area.
