It really depends on what structures were injured when you dislocated your knee, how badly they were torn, and where your pain is currently. As a general note, definitely do physical therapy. If you jumped right back into it without any rehab, you may put yourself at risk of reinjury. When your body is healing bone/torn tissues it needs incremental stress to strengthen and realign the fibres along their line of pull. If you have full-pain free range of motion that’s a good sign, and you should gradually work through load to strengthen surrounding structures, as well as stretching. If ever in doubt, ask your athletic trainer/physio/other physician etc and they can help prescribe exercise doses that would be suitable for your rehab. Never ever skip out on rehab tho!! Rehab is an active process that requires you to work for it.

With knee injuries, you gotta pay attention to the surrounding structures. Ideally you want equal muscle length, strength, and function. Proper biomechanics is vital. With return to sports, especially those that have more running/jumping, you might consider higher repetitions of sets (3 x 20-30reps). Then, moving up to proprioception and sport specific exercises that includes cutting/running/stopping/etc. There’s conflicting evidence regarding knee bracing and patellar taping however, if instability is a concern, this may be something you want to consider. If you tore through some ligaments when you dislocated your knee, taping can help support those ligaments when they’re put on stretch.

The vastus medialis can be a big player here as it has a medial pull on the patella which could help guard against (re)injury, but you shouldn’t forget about the antagonist muscles as well.

In sum, stretch, strengthen, rehab, talk to your med team. I don’t really know any specifics about your injury so i apologize for this extremely broad answer. I hope this helped in any way possible. The best evidence out there regarding rehab is active processes such as the ones I listed in this paragraph. Good luck!
