Abstract
While cyclops lesion, a fibrous nodule on the tibial side of the knee joint, is a well-known condition complicating anterior cruciate ligament, inverted cyclops lesion, a fibrous nodule on the femoral side of the knee, is a relatively less known condition. We report a case of inverted cyclops in a patient who presented with chronic knee stiffness eight years after supracondylar nailing of a femoral shaft fracture. There are only four reported cases of inverted cyclops in literature. Literature has been reviewed and the importance of not missing such a lesion is discussed.
