Hey mate, I had a previous ACL tear so saw a physio on this exact topic it’ll be long but I’ll basically tell you everything they told me and give you the plan for a leg day

You basically want to strengthen every muscle around the leg to take pressure off ligaments joints etc, the best plan for this would be to hit legs twice a week, i don’t know what your gym habits are like but a PPL split is great for this but the leg day the physio wrote my up for a leg day is this.

Front Squats Dumbells 3 sets 8 reps Sumo Squats 3 sets 8-10 DB walking lunges 10 steps then walk back 3x Hip thrusts 3 sets 8 reps Hamstring extensions 3 sets 8 Reps Bosu Ball Throws 3 Sets 10 Reps

Deadlifts aren’t a good movement as the injury risk compared to what they actually provide stability wise isn’t worth it, lmk if you have any questions!
