Mri bilateral. Without surgery?

Question: Hello Doctor, I had a recent accident and now have pain in both knees. I got MRI scans done for both knees. Right knee findings: Mild ACL sprain Mild MCL sprain Grade 1 chondromalacia patella Minimal joint effusion Mild swelling Left knee findings: Mild ACL sprain Grade 2 chondromalacia patella Minimal joint effusion Mild swelling Currently, I feel pain while walking and some discomfort while bending my knees. I would like your advice on: Which knee is more serious and needs more attention? Do I need complete rest or can I continue light walking? How long will recovery take for both knees? Is physiotherapy necessary? When should I start? Can this heal completely without surgery? What medications or precautions should
