A neuroma is a small knot of nerve endings, which can form when a nerve has been cut.

 

What causes a neuroma?

A neuroma is really an attempt by the damaged nerve to heal itself, but something goes wrong with its attempts. A neuroma can form in the tissues around the knee after an injury or after knee surgery. One of the commoner neuromas affecting the knee can follow a surgical injury to the infrapatellar branch of the saphenous nerve.
