i did stem cells years ago. I do have the stem cell brace that really works. I do have pain sometimes but in my right knee i had tkr and it hurts all the time and now it has come lose after 5 years. I have found that PRP tends to make knee feel better. I am 79, feel like 50 and ride my bike a lot in the summer. Do not like to walk. Play golf and garden. I am holding off doing TKR as i had such a poor experience with the first one. No easy answers. I went with regenexx dr.
No question it is expensive. If you have bone on bone do a TKR. Stems will not help you. Your DR should advise you. Maybe someday i will have to do TKR and then how do you garden? Getting on your knees is painful.
