question: Hi. My daughter is 7 years 9 months. About a year ago she experienced pain and locking of her knee with a weird bending motion. Since then she has had it happen several times. It makes a popping sensation, feels stiff until it is straightened, and the pain is located on the outside aspect of the knee. I know I need to see a physician for this, but I talked to the pediatrician and she said to just not bend the knee in a way that causes pain. My daughter doesn t do this intentionally, and today she pivoted in place and had a bout of extreme pain in which she didn t want to walk on the affected knee. What could be the problem? A meniscal tear? It doesn t seem like that would be likely in such a young child. Thank you for you help.
