What is the best program for relieving knee pain in an 80-year-old woman caused by osteoarthritis?
Hi Joaquim! Welcome to the Aha community, and thank you for your question. 
For general wellness support related to knee joint discomfort, you may want to explore Joint Discomfort (P). You can also consider Joint and Cartilage as additional programs for joint mobility and everyday joint support.
Since the discomfort is related to osteoarthritis and involves an 80-year-old woman, we recommend using Aha Halo as a complementary wellness tool alongside guidance from her healthcare professional rather than as a treatment for osteoarthritis.

We hope this helps, and please feel free to ask if you have any other questions.
