MRI has been shown to be 84% accurate in detecting cyclops lesions (2) and surgical intervention is generally successful in restoring knee function (8). Splinting or bracing may be used for extension deficits. The development of patella baja is made more apparent by comparing current and prior studies by plain film or MRI (Figure 11). Lenny Macrina: Without knowing what excessive hyperextension means in the question, I'm going to assume it's that excessive like 10, 15 degrees of hyperextension, which is a lot for some people.

Cyclops lesions develop in the anterior aspect of the intercondylar notch typically after anterior cruciate ligament (ACL) reconstruction or injury. 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 cyclops lesion is a localized anterior arthrofibrosis most commonly seen following anterior cruciate ligament reconstruction. It is a frequent complication associated with surgery and trauma.

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. When cyclops lesions measured more than 10 mm . Petsche, T. S., & Hutchinson, M. R. (n.d.). Results Cyclops lesions were found in 25% (28/113), 27% MRI is effective as a tool to evaluate unexplained pain, limited range of motion, and functional limitation in the postoperative patient in whom arthrofibrosis is suspected.

An 18 year-old female 5 months after ACL reconstruction with pain and diminished range of motion. Unresolved deficits warrant further intervention including manipulation under anesthesia, arthroscopic debridement, and open debridement. At present, increasing the accuracy of identification of knee ligament insertions is fundamental in developing accurate patient-specific three-dimensional (3D) models for preoperative planning surgeries, designing patient-specific instrumentation or implants, and conducting biomechanical analyses. The great part about this exercise is that it can be performed in a more functional, weight-bearing position. Large graft relative to intracondylar notch, slightly higher incidence with double bundle compared to single bundle for this reason.

Sanders TL, Kremers HM, Bryan AJ, Kremers WK, Stuart MJ, Krych AJ. Sagittal proton density-weighted images demonstrate the normal appearance of the infrapatellar fat pad on the left and the typical mild post-surgical scarring following ACL reconstruction (arrowheads) on the right. The patient had a range of movement of 5130 post-operatively and at 2 months following excision of the lesion she had full active extension, flexion to 130 and a stable knee with negative Lachman, anterior drawer and pivot shift tests. Motion Loss after Ligament Injuries to the Knee. The cyclops lesion, also known as localized anterior arthrofibrosis, is a painful anterior knee mass that arises as a complication of anterior cruciate ligament (ACL) reconstruction, although has rarely been reported in patients with ACL injuries that have not been reconstructed. Torn anterior ACL graft fibers remain continuous with the graft in the tibial tunnel and are folded anteriorly (arrows) resulting in a pseudocyclops lesion.
