Severe Knee pain for three months

I have mild patellar tendonitis, edema and partial damage of the ACL (no rupture), grade 1 chondromalacia patellae, joint effusion, and a developing Baker’s cyst. I’ve seen a doctor and tried physical therapy, but it didn’t really help. What are some effective ways to manage this at home and speed up recovery? Any advice on exercises, treatments, or supplements would be appreciated. Thanks!
