12 months ago I ruptured my ACL (femoral avulsion). The 42nd person to use Cross ACL bracing protocol (non-operative rehab). Returned to surfing 4.5 months and Australian rules footy <6months. Complete confidence in knee stability. 3 scans show healing at 0-, 3.5- & 12-months
Move. Often easy. Occasionally with ferocious intensity.
Get out and move. Most should be easy to moderate so you can keep coming back day after day. Some should be moderate/hard. And very occasionally you should "go see god" to remind yourself what going to the well is like.
