Locking is when the knee suddenly gets caught in a bent position, and it is impossible to straighten it without assistance.

 

Causes of knee locking

Knee locking may be due to a loose body or a torn piece of meniscus catching in the joint, most often a 'bucket-handle' tear of the meniscus. An unstable tibio-tibular joint may also rarely be a cause of locking or pseudo-locking. Very rarely a locked knee may have a more sinister cause, such as a tumour obstructing the hamstrings.
