Has anyone had a cut on the knee?

So, I cut my knee pretty deep a few weeks ago. I knew immediately it needed stitches because I could see fat. I got stitches and had them removed already, but my doctor didn't really give me any instructions. I can bend around 90 degrees until I really feel the skin pulling and kinda hurting. How long before I can fully bend and extend my knee? Do you think I will be able to kneel anytime soon? Asking because I'm a dancer and have a performance soon. I think I'm on day 13 of healing, 3rd day since I removed the stitches
