really depends how the Diagnostic goes mate, Its not totally uncommon for the Physician to find something unexpected and make another incision. if its a general give it some time until atleast the stitches are gone and the skin isnt red anymore.
Id be more inclined to say to forget about squats and stress movements at least 10-12 weeks min after any cartilage trim, Internal stitching or reattachements or replacements. Buts thats general adivce, Get the surgeon to give you the heads up mate.
