@melia7 I broke my patella (kneecap) about 20 years ago. I fell on the ice while I was skating. At least it was a good story at the time because I was doing something fun. I was in the osteopenia range at that time. My orthopedic doctor put me in a leg brace that I could take off to bathe but otherwise I wore it for about 6 weeks. My doctor told me, after the x-rays, that since I did not tear any of the tendons and attachments to the knee that I did not need surgery. After I healed I did not have any other problems with that knee.

By the way I was in the osteoporosis range when I had a total hip replacement five years ago. My orthopedic surgeon told me at the time that while my bone was "soft" he did not think with this intervention that the osteoporosis would influence my healing.

I don't know if casting is now used for a kneecap fracture. If I were you I would try to get in to see an orthopedic physician and get their opinion on your knee. I have found that emergency and urgent care clinics sometimes Under-treat or over-treat and it's wise to get follow-up.

What do you plan to do next?
