Good evening @ezas123 There are some pretty standard recuperative exercises. Here is a link to some on-line
options:

Perhaps Maria can help you select the best ones to improve your ROM. Also, you want to straighten your knee and make your extension a zero. The ones that helped me the most were the ones you hold for 5 or 10 minutes.

The one that helped my ROM is the one where you slide your foot on the carpet or a towel on a hard floor.....from straight to bent and hold for 5 seconds.

There is also a Youtube program with a couple of gentlemen. Here are their names and you can select videos for post-surgery.

Please let me know how it goes. I am sure you can master this. Tell me about the exercises you choose. If there is discomfort.....that is to be expected. You can always ice and elevate to reward yourself for good effort.

I am thinking about you......wish we had a 2-way camera so I could cheer you on.

May you be physically well
May you be mentally well.
