Some guidelines I have seen are:
who should be reconstructed?
fit young active people involved in sports with cutting/pivoting or have physical job,
more sedentary people if c/o giving way,
good prehabilitation 45 min cycling pain free.

Natural history: 44 pts ACL rupure Wikipedia reference-linkmeniscus normal, 30% marked instability and unable to play, 70% return to play average 5.7 wks, 61% who returnied to play had reconstruction within a year

Hope this helps
