The site "XL Athlete" has all types of exercises for every area of the body.
Most find that with multiple joint exercises like the squat and deadlift that they don't need to do many of the exercises on this site.
But since you obviously won't be able to do squats, deadlifts, lunges and other "common" exercises, you may want to look at some of the many other exercises listed, particularly for the "core" and "single leg training".
Hopefully you will find some "new" exercises for yourself that can keep you in relatively good shape until you can return to your usual routine.
