This is Dr. David
your stroke was back in 2000?
you need an ultrasound or MRI scan of your knee
you could be having large baker cysts behind your knee or severe arthritis in your knee preventing it to bend which can affect walking
you may need a steroid injection into the knee.
not being able to bend your knee most likely is not due to your stroke back in 2000.
you may need more physical therapy to help your right leg gain strength
do you have an orthopedic doctor or primary care doctor you can see who can examine your knee? and do some testing for you?
let me know if you have other questions.
