Soft Tissue Injuries ATSHTF

Blessings, Darlings!

Given my on-going knee problems (tore my medial meniscus last spring), I've been contemplating these types of  injuries in an ATSHTF (after the shit hits the fan) situation.  While I can't afford surgery to repair this, at least I know what it is and have physical therapy exercises that usually keep the knee functional.

But with the increased physical effort needed to survive ATSHTF, these types of injuries will be more common and treatments more limited.  Broken bones can be set. Wounds can be sutured. Disease has avoidance and treatment parameters.

But, torn ligaments, torn cartilage, torn rotator cuffs, arthritis - we're going to have to deal with the pain and limited movement and go on with life.  Even access to list of physical therapy exercises will be limited, since without MRIs/X-rays/cat scans our ability to accurately diagnose the problem will be limited, and surgical correction will be right out.

Has anyone our there addressed these issues?  I've not found anything about them yet.

Frondly, Fern
