Tonin et al reported it in patients with ACL injury without reconstruction surgery.4 In the absence of surgery, the origin was thought to be due to avulsion of pieces of bone from the attachment of the ligament. A MRI looking from the side shows the cyclops lesion (dark patch) protruding anteriorly. MRI can assist in the evaluation of arthrofibrosis in patients with a normal radiographic appearance of the implant but with a limited range of motion.17, MR imaging findings of diffuse arthrofibrosis include widespread heterogeneous thickening of the synovium. But I felt a strange pulling sensation and a pop like sensation. Cyclops lesions develop in the anterior aspect of the intercondylar notch typically after anterior cruciate ligament (ACL) reconstruction or injury.

Loss of full extension after anterior cruciate ligament (ACL) reconstruction, with development of an audible and palpable "clunk" with terminal extension was first described by Jackson and Schaefer as "cyclops syndrome." The tract of the transtibial pullout repair extends obliquely through the tibia (arrowheads). Also, moving your knee in & out of terminal extension helps develops hamstring and quadriceps control which can be lacking post-injury. KOOS was also correlated with lesion volume.

The cyclops lesion, a well-known complication of ACL reconstruction surgery, is an ovoid fibroproliferative nodule found anterior to the ACL graft. Both true and cyclopoid types are simply referred to as cyclops lesions, and they are usually indistinguishable by MRI. This results in the formation of a nodule of fibrous tissue in the anterior portion of the ACL graft (Tonin et al., 2001). Previous studies reported that after ACL reconstruction, the incidence of joint stiffness was between 4 and 38% [8].
