How do I treat post-stroke knee pain?

Thank you for your question. Persistent severe pain after a right knee replacement is abnormal especially when her other knee replacement was doing fine. I'd strongly advise you bring your grandmom for a checkup and we'll need to do a thorough investigations including X rays, blood tests and advanced imaging (MRI/ CT) to find out what is the cause of this persistent pain. The cause of persistent pain would include infection, implant malposition, cement fracture or referred pain. Only after the cause of the persistent pain is identified then we can talk about the treatment.

I’m in awe of your dad! Kudos to him for his commitment to keeping fit and healthy. If only the rest of our population could do that – we would certainly have much fewer people in hospital. In the absence of any other information leading up to his knee injury (ie did he suffer any knee trauma, suffer a fall while running, hear a pop and twist his knee etc), his injury sound like it’s training volume-related, or an overuse injury – he’s clocked up quite a lot of miles, and it seems like even with his injury, he hasn’t actually held off with his training.
