I'm guessing you're having an arthroscopy. If all they do is take out the loose piece, you should be able to fully weightbear in about 2-3 weeks, as a safe guesstimate. everyone's different. i had one arthroscopy where all I had was a trim of a hangnail tear, and didn't even have crutches, and have had other arthroscopies where it took 2-4 weeks to get off the crutches. So, it varies a lot.
