well my sons legs at the knees bend really far back, when he walk he seems to be ok but when he stands still he gets stuck it that position and he can t move and when i unbend his legs he cries out in pain, is this something really serious? what should i do?
Hello, It could be due to trapped foreign fragments in the joint cavity. If symptoms persist better to consult an orthopedic and plan for an MRI scan. Hope I have answered your query. Let me know if I can assist you further.
