Dr. Dugan discusses what knee locking indicates.
Locking of the knee can be an indication of a torn meniscus. The meniscus is like the washer that lives on the inside and the outside of the knee that goes between the femur bone or the thighbone, and the lower leg bone in the tibia. If you get a tear and that tear folds over, it can actually cause the knee joint to lock.
