The anterior interval of the knee is found posterior to the patellar fat pad and anterior to the anterosuperior tibial plateau.2 Scarring over the posterior aspect of the infrapatellar fat pad from the patella to the anterior surface of the tibia or the transverse meniscal ligament can bridge the interval and result in restriction of the normal biomechanics of the anterior knee with increased tension on the fat pad, diminished translation of the patellar tendon and patellar entrapment (Figure 10).15.

Sports Injury Bulletin brings together a worldwide panel of experts including physiotherapists, doctors, researchers and sports scientists. It occurs at the anterior portion of the graft and protrudes from between the femur and tibia at the intercondylar notch (2). On MRI, cyclops lesions are adherent to the ACL graft and are hypointense or isointense to muscle on T1-weighted images and variable in signal intensity on proton density- and T2-weighted images.4 Rarely, areas of ossification within the cyclops lesion are well formed and large enough to be detected on MRI as circumscribed foci with internal signal that mirrors marrow fat signal on T1-weighted and fluid-sensitive sequences (Figure 4). When I mention the word cyclops it might conjure visions of a giant one-eyed beast from your nightmares but this type of cyclops is more of a physiotherapists nightmare.
