Domiciliary physiotherapy services in London, UK

Hey folks,

I'm a 33-year-old male with haemophilia A and osteoarthritis of the right knee. The knee has been locked at about 90 degrees for 6+ months, and remains painful. My left ankle was fused 7 months ago but hasn't had its rehab because of the knee problem I just mentioned. I'll be having a total knee replacement surgery for the right knee in February or March. I want to do whatever I can ahead of that surgery to get the best outcome possible. I live in NW10, London. Could you please point me to some domiciliary physiotherapy services that I could use?
