I recently ruptured my patella tendon and after surgery and being wrapped up in a brace for 6+ weeks (currently in week 5), I found the process of getting dressed quite challenging. I looked online to see if there was a solution for clothing but to no avail. As a result, my wife and I came up with a design for shorts that open/close on the side hem making getting dressed MUCH easier to the point where I am, once again, getting dressed independently (at age 37 no doubt) ;-)
After chatting with other folks, I've received overwhelming feedback that this will help other people with limited ability to bend their knee as well. So I decided to offer the shorts on ebay. I hope this helps others the way it has helped me.
