Fusion

Hi there, I'm a 31 year old male that has had 7 surgeries on my right knee. I have 50% of my medial condyle and 50% of my medial meniscus left switching to the lateral compartment I have 0% of my lateral condyle and 0% of ny lateral meniscus remaining, Degenerative arthritis. basically I have a knee of an 80 year old man, but I'm 31. I cannot have a patial replacement due to the disease in my medial compartment as surgeons feel that there would not be any success with this operation. I cannot have a TKR as the surgeons feel the my body would use 2 knee's by the age of 40, and fear that my Tibia and femur would rot away. My only option right now is fuse my knee to save the chace of a TKR on the road when I'm 40 -45 years old. I'm trying to find someone roughly around my age group that has had this procedure. Looking for some info on vehicle modification, pain , recovery, functions, abilities, downsides, etc. You help would be greatfull. Thanks
