I was stepping over a baby gate and smacked the top part of my left knee cap really hard. I can walk and have all normal ROM. It does feel like a tendon or something is sliding over something when I bend it completely. Also it feels like a dent on my knee cap where I hit it. Not having insurance at the moment I dread havin to go to the hospital.
Dear Sir/Madam have gone through your query and read your symptoms. In my opinion, if you do not have pain, and can move your knee to the full range without any discomfort, rest assured you are normal, as far as indentation goes, it may need an X-ray to find out the cause but no intervention will be needed. I hope that answers your query. If your want any more clarification, contact me back. Chat Doctor.
