What makes my knee cap sting after popping?
Patient: Hi my 13 year old son was at his dads house all week till about 10:15 tonight apparently he dislocated his right knee cap yesterday at about 7:05pm while helping to move a picnic table and he poped it back in place and his dad said nothing was wrong with his knee and made him walk on it till he got to my house at about 10:15pm today and now he says it stings and he can move his leg but he can t move his leg all the ways you usually can without it stinging really bad what do we do? Doctor: Hello,I have studied his case and i think that he must have injured his ligament which is useful for knee patella stability. It can be confirmed with the help of x rays and Mri. If there is ligament damage thence will need plaster for three to four week. if there is severe damage then he might need surgery. If you want then you can share his MRI details with me. I hope this answer will be useful for you. Let me know if there is any other followup questions.thanks
