Stiffness and struggling to get bend after knee replacement

Hi folks, I had my right knee replaced 18 days ago. I had my left replaced 5 and a half years ago. From day 1 of the first knee i xould bend my knee to 90. This time so different...from day 1 I have found it very hard ro get the bend past 60 degrees. My physio while in hospital knew I was having difficulty and sent me home to keep trying and I am really struggling. With ly last knee i could use the skateboard to get movement but not this one, it is so stiff and tight. Has anyone any ideas? Thank you Suz

Try using heating pad and massage some transdermal pain lotion, or a rx pain patch on the area, then wait a few then use the heat. Hopefully you will less pain . Some times it works or use ice instead .

Thank you, I will give heat a try, I do regularly ice. Thank you

I sit on the end of a chair and pull my bad knee backwards with my good leg. Hope this helps,

Thank you Kevin, i will give it a go. will try anything!
