The most common problem caused by a torn meniscus is pain . The pain may be felt along the joint line where the meniscus is located or may be more vague and involve the whole knee. If the torn portion of the meniscus is large enough, locking may occur. The fragment of meniscus gets caught in the hinge mechanism of the knee and will not allow the leg to straighten completely. The constant rubbing of the torm meniscus on the articular cartilage may cause wear and tear on the surface, leading to arthritis of the joint.
Diagnosis begins with a history and physical .
The examination will try to determine where the pain is located, whether or not locking has occurred, and if you have any clicks or pops as the knee is moved. Xrays will not show the torn meniscus. They are mainly useful to determine if other conditions are present. If the history and physical examination strongly suggest that a torn meniscus is present, then arthroscopy may be suggested to confirm the diagnosis and treat the problem at the same time. Initial treatment for a torn meniscus usually is directed towards reducing the pain and swelling in the knee.
