Brief Answer:
Physiotherapy...

Detailed Answer:
Hi,

Knee joint pain is common in seniors; the age related degeneration leading to osteoarthritis is the probable cause. Has she consulted orthopedic surgeon in the past? If not, it would be crucial to visit one to understand the severity of degenerative changes.

While she seeks to see a doctor, I would start calcium and vitamin D supplements along with glucosamine and chondroitin sulfate supplements. Pain killers can be used for a short period to treat severe pain. Physiotherapy techniques will also be handy in treating the problem.

Hope this helps. Let me know if you need clarifications.

Regards
