See Orthopedics: Your specialist the Orthopedic doctor can prescribe treatment options. They include surgery, no surgery, rehab, injection, meds to name a few. The cartilage as you know does not regrow. Over weeks the area will heal and pain will go away. You may have knee instability. Use a knee brace from pharmacy if that is useful. Take OTC ibuprofen if pain. As always see a doctor for complete care.
