Cyclops

Arthroscopic image of a cyclops in a patient's knee.

The Cyclop ( engl. Cyclops lesion ) is a usually after a cruciate ligament of the knee occurring complication .

Cyclops is scar tissue in the anterior joint space, which includes the ligament replacement and can mechanically prevent full extension from being achieved. This change occurs after approx. 15% of the operations, but only leads to a noticeable inhibition of extension in 2% of the patients. In such cases, the cyclops usually has to be removed surgically.

The term was coined by the Californian orthopedic DW Jackson and RK Schaefer that the arthroscopic appearance of scars node with surrounding blood vessels to a Cyclops had remembered.
