Key points: Cyclops lesions had a prevalence of 25% in patients after ACL reconstruction. An arthroscopy four months after the original surgery showed a cyclops lesion at the roof of the femoral intercondylar notch the inverted cyclops lesion (Fig 1). Increased preoperative and postoperative inflammation reflected by swelling, effusion, and hyperthermia also plays an important role in the development of this complication.7,11 On MRI, fibrotic tissue encases the ACL graft and can extend anteriorly into the infrapatellar fat pad and suprapatellar bursa or posteriorly to the posterior joint capsule (Figure 8).7.

MR imaging showed a well-defined, somewhat heterogeneous soft-tissue nodule with a signal intensity typically similar to that of skeletal muscle. The cause of arthrofibrosis is multifactorial and incompletely understood. Various terms have been used to describe this pathology including infrapatellar contracture syndrome, synovial fibrosis of the infrapatellar fat pad, scarring of the anterior interval, and patella infera syndrome.12,15,16 Postoperative scarring normally appears as thin linear or spiculated regions of low signal on all sequences with small slightly thickened and more nodular portions found along the route of the arthroscopic portals and at the posterior margin of the fat pad (Figure 9).16 In contrast, symptomatic fibrosis results from more extensive fibrotic changes appearing as thickened and irregular areas of low signal on all sequences, which can greatly reduce the amount of normal fat.

Arthrofibrosis is a common complication of ACL reconstruction and total knee arthroplasty and can result in a frustrating clinical course and poor functional results. Cyclops lesions are located just above the tibial tunnel and cause loss of knee range of motion with a mechanical block that restricts getting the leg completely straight following surgery. The axial proton density-weighted image (13B) reveals this structure to be a band-like region of arthrofibrosis (arrowheads) passing posterior to the patella and blending with the synovium medial and lateral to the patella, likely contributing to the patients mechanical symptoms.

If the physiotherapist pushes the patient too hard in the presence of a cyclops, it may trigger breakdown of the articular cartilage. (2B) On the T1-weighted sagittal image, the nodular focus anterior to the ACL (arrow) is heterogeneous but almost isointense to the joint fluid and articular cartilage with subtle central areas of reduced signal. For those not familiar, a cyclops lesion is a wad of scar tissue in the anterior aspect of the knee joint. The incidence of arthrofibrosis following TKA is approximately 4%.17 Arthrofibrosis as the cause for TKA revision ranges from 4.5 to 6.9%.18,19 Multiple factors affect the development of arthrofibrosis following TKA, including surgical technique, component selection, post-operative rehabilitation course, underlying patient-specific disease and genetic factors, and preoperative range of motion.18,19Some authors suggest a relationship between diffuse arthrofibrosis and chronic infection.18,20,21 Pre-operative range of motion appears to be the most important predictor of postoperative stiffness.18,20,22 Arthrofibrosis associated with TKA most often appears within 5 years of surgery.19 Stiffness and arthrofibrosis developing after 5 years is often associated with other complications such as aseptic loosening, infection, or polyethylene wear.19, With specific techniques and modifications to reduce metal artifacts, MRI is effective in evaluating the complications of TKA including implant loosening, periprosthetic infection, fractures, extensor mechanism injury, polyethylene wear, and arthrofibrosis.

Predictive risk factors for stiff knees in total knee arthroplasty. Hypoxia acts to stimulate further fibroblast proliferation and extracellular matrix and also induces the metaplastic conversion to fibrocartilage, which can undergo enchondral ossification and result in heterotopic bone formation.1, Arthrofibrosis following ACL reconstruction can present as a focal or diffuse process limiting the mobility of the knee. The triggering insult stimulating the formation of a cyclops lesion is unclear with theories including an inflammatory response to drilling debris from the tibial tunnel, remnants of the native ACL, and from scar tissue and piling up of graft fibers arising from repeated graft impingement.3,1,4No clear difference in the incidence of cyclops lesions is found between bone-patellar tendon-bone and hamstring allografts.5 Muellner et al. One case has been reported previously following a bone-tendon-bone reconstruction of the ACL but a similar case has not been reported. Menu 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). A 66 year-old female 10 years post ACL reconstruction with intermittent locking. One common complication of ACL reconstruction is a limited range of motion, especially obtaining a fully straight knee. When I try to really squeeze it straight with my quad I can get close but I feel a pinch underneath the kneecap. Scarring and contraction resulting in a foreshortened suprapatellar bursa leads to further loss of knee flexion.2, Fibrosis of the infrapatellar fat pad appears to be an important cause of pain and stiffness.12,13 The infrapatellar fat pad is susceptible to trauma at the time of the ACL tear, from untreated instability, and from subsequent arthroscopic surgery and ACL reconstruction.

In severe cases of infrapatellar fat pad arthrofibrosis, fibrosis between the patella, patellar tendon, and tibia can result in severe retraction and tethering of the patella leading to patella baja which may become progressive (patella infera). It may be more comfortable to have the weight applied either side of the knee joint if the knee itself is sore.
