I am 75 years old and in good shape except my knees hurt when I go up and down the stairs .
I tore my ACL about 23 years ago and did nothing but pro lo shots which wirked beautfully.
My knees are not bad enough yet to get a replacement so i am looking into prp or stem cell and I would like to know what each cost  per injection and how long I can expect it to last.
I just got another prolo  shot ladt week and it helped but not as much ss it use to.
I am taking Physical Therapy and that helps a little too.
My thinking is it would be better to do the stem cell before I’ll start really having problems and can’t walk. I had trouble getting off of my knees to a standing position without holding on to something to pull myself up.
Please let me know what the cost would be for each of those ?thank you linda fauhl
