Make a list about what you expect from this doctor. Like i am looking in my rheum to be team player with me. They give me options on treatment and from their knowledge i then decide. I am always upfront about this even when i make first appt.
I have learned though to ask questions like how long they give for each patient...policies, will they work with all my doctors involved with same health problems.
If you they want to be GOD then i just say this is not going to work and leave or if they want to diagnose me again. I have had MCTD for over 30 years now and do not need to be diagnosed again lol!
As to your knee...a lot depends on your age. I have wrecked toe and ankle joints and yes i have had surgery done on them to replace cartilage. BUT as to joint replacements, both doctors and research backs what they say that i have to wait until my late 50's or 60's since they only last 5 years for someone like me that walks daily. I run out of bone to connect replacement too if i had started even in my thirties. It started in my early twenties.
NBC has basics about knee replacement surgery and what it involves etc...and of course a ortho is going to say surgery, they are surgeons after all!! lol! I never go to one and not expect them to say no! That is how they solve othro problems where rheum will take in your full life and think about at 60 what options you will have.
I know people who had to get hip replacement surgeries due to genetic problem( born with deformed hip joints) at 40 she needed new ones but did not have bone to attach them too. She had to keep going on what she had until the glue literally ate bone she did have away...than they had no idea what to do...not one specialist.
you do not want to end up like that....so do the research, ask the rheum why they feel that way. Let them explain, they might have logical excellent reason why you should wait. I really look into how long knee replacements last too. My toe joints only lasted 5 years at longest 25 yrs ago and still is like that....same with ankles...or bit longer but not even 10 years!
I get how painful it is...i hope you are walking still despite the pain. There are other options you can do for the pain besides narcotic pain medication like i eventually turned too...i wish i had used other options now...that my body is physically addicted and pain doctor left. i am in pickle!!
So i hope i gave you some things to think about and will help. I write down what you expect and want from your doctor most of all ....so you have clear idea and can explain it so you are all on same page and know immediately if it is working relationship.
I have had great rheum and bad ones....just like all doctors. So my experience has been they are same as most other doctors good and bad. i wish you the best and hope your find solution that works for you knee pain.
