- Is this an acute problem, or has is it started slowly without a known injury?
- Is there swelling associated with the pain?
- Is the pain related to certain activities, or does it occur at all/any times, even at night?
- Are there mechanical symptoms of locking, catching, or buckling that are associated with the pain?
A good physical exam from your orthopedic surgeon can help to delineate whether the pain and locking sensations are coming from a torn meniscus, or some other structure in the knee. In many cases, an MRI exam is used to visualize these structures, as X-rays can only see the bones of the knee joint.
