Half knee replacement

I had a half knee replacement done it will be 10years on the 1st April 2019 anyone know if they last longer than 10year. As I've also had a tkr done on my other knee 9maths ago any help plz

I have had both knees done. First tkr was 20 years ago other was 18½ years ago and both are ok with no problems. If you look after them they should last a long time. You should have plenty of use left in them.
