Nolt likely. By cartilage degeneration, I am assume you mean meniscus degeneration. This is not list as an adverse event. Also on nlm search there were no articles that reported any meniscus problem associated with Accutane use. Joint pain and musculoskeletal symptoms are not uncommon. If you mean arthritis, it has been reported as an associated adverse event and is mentioned in the package insert.
Not listed. It can cause major birth defects and has a number of skeletal and psychiatry side effects, but I have not found knee cartilage deterioration listed as a side effect. This is a medication that is restricted in its use because of the serious side effects.
Knee cartilage deterioration, moderate narrowing, small joint effusion, periarticular spur fluid; MRI clear yet terrible pain. What can be done now?
Knee pain. Sounds like there is some arthritic changes--and I suspect MRI has ruled out meniscal tear. If not responding to high dose nsaids ie aleve (naproxen) or Ibuprofen and rest--to orthopedics and may need a procedure.
Can deterioration of the knee cartilage affect the whole leg? (by way of muscle strain, cramps, or weakness when stepping)
Yes. Probably best see your primary care or rheumatologist.
Very Good Chance! If your knee cartilage is damaged, your knee will not function correctly. Most folks will favor the other knee, or alter their body mechanics to compensate. This may with time lead to dysfunction in other areas. Your body can also involuntarily stop firing muscle groups to try to protect the injured knee. A good physical therapy program or home exercises may be an option if early enough.
No. There is no evidence that any of these foods are helpful for cartilage health.
I do not believe so. But if you like the way it taste, no need to stop.
Multiple. There are many options, including arthroscopic drilling; cartilage harvesting, groth, and then implantation; visco supplementation; braces and osteo roomies to " offload" the area, joint resurfacing, etc. Don't hesitate to see an orthopedic surgeon to discuss which option would be best for you.
