Meniscal tear: there are multiple possibilities, but of you injured your knee and it is now "locking up" on you, you may have sustained a meniscal tear. The knee has two menisci that act as cartilage suctions between the femur and tibia. When they are injured they can tear and this is one of the more common causes of a knee locking up. Dont hesitate to be seen, an MRI may be helpful.
