Take a look at Infra red light therapy. It does promote healing and increases circulation (release of nitric oxide), ATP production and healing. Trying some of that with your hip joint to see if it helps. NASA has been investigating this for astronauts and there is quite a bit of research into it's positive effects. Once you have your hip replaced you will not be able to go back!
I became aware of this a few days ago and intend trying it myself as soon as I can find a suitable device which is proving difficult ATM. I had some thoughts that if it can improve ATP production it might be worth trying in the liver area.
The wavelengths of light are important as some are more effective than others.
Both red light 630 to 660nm and near infra red light at 810 to 830nm are effective. The dosage should be kept low, 20 to 30 joules/cm^2 is ideal, 100 joules is too much.

There are heat lamps which can do this but their energy output is a bit high for my liking. LED lights are more controlled but are more expensive. All this can also help with pain.
If you can stimulate ATP production and healing you might be able to avoid having a hip replacement. Joint replacements are prone to bacterial infections which can be very problematic. Biofilms can become attached and make destroying them very difficult.
DPL make LED products but purchasing them in Europe is difficult. DPL Flex system and others.
Beurer make Infra Red lamps but I am not too keen on them. They put out heat which can be a bit damaging if you are not careful. I would like an LED system but ATM I have not found something suitable which I can purchase.
I also came across some research about infra red (870 and 930nm) and it's ability to damage bacteria. This is something that I would like to investigate to see if it helps destroy the bacteria that I believe cause CFS. Everything that I have tried so far has only had a small effect and has not destroyed them. They must die but actually destroying them is extremely difficult.
Another good article which shows the beneficial effects of light on the body. It's quite a long article but well worth reading.

Best of luck with whatever you choose.
