I went through all the myriad injections, topicals, pills, and witch doctor cures for years. Finally had both knees replaced in 2020, one in February, the other in July. The surgeon used a "robot" to guide the cutting. I'm wishing I had it done 10 years earlier! I walk at least 1 1/2 miles a day, weather allowing, with little to no pain. I DID lose 25 lb prior to surgery, which helped with recovery.
The absolute best favor you can give yourself is to religiously follow the rehab regimen. I was off the walker in 2 weeks, and the cane in 5 both times.
