Arthroscopic Anterior Cyclops Lesion Excision After Autograft Quadriceps Anterior Cruciate Ligament Reconstruction: Technical Note and Review of Literature

Abstract

Anterior cruciate ligament (ACL) injury is one of the most common injuries of the knee. The current primary treatment in symptomatic patients is ACL reconstruction with either an autograft or allograft. In recent years, the quadriceps tendon autograft has emerged as a popular graft choice given its promising biomechanical properties and short- to mid-term clinical results. However, several graft-specific morbidities can occur with the use of a quadriceps autograft (e.g., arthrofibrosis, cyclops syndrome, knee extension deficit, and quadriceps weakness). In this technical note, we describe a surgical technique for debridement of localized anterior arthrofibrosis with a cyclops lesion after quadriceps autograft ACL reconstruction.
