A cyclops lesion is localized arthrofibrosis anterior to the ACL graft. It may present with knee pain or reduced range of movement. The differential diagnosis for a cyclops lesion includes focal pigmented villonodular synovitis , synovial chondromatosis and intra-articular loose bodies MRI of a patient with a previously reconstructed ACL, demonstrating a rounded soft tissue mass in the intercondylar notch representing a cyclops lesion. Case Discussion The images are from Dr. John Hunter's amazing MSK collection A rounded fibrotic lesion with moderate vascularity (scar tissue) has formed between the anterior border of the ACL graft and Hoffa's fat pad.

  2. The cyclops lesion is a fibrous nodule in the anterior intercondylar notch anterior to the tibial insertion of ACL. Cyclops lesions were initially reported to occur in patients after ACL reconstruction, with an average interval time of 16 weeks between repair and arthroscopy
  3. This area of fibrosis limits complete extension of the knee because the graft is trapped between the femur and tibia. The focal form is commonly referred to as a cyclops lesion because of its arthroscopic appearance resembling a head with an area of discoloration resembling an eye

A cyclops lesion (2.2 × 1.4 × 2.4 cm) was seen anterior to the ACL in the intercondylar notch. The lesion demonstrated a mild heterogeneous intermediate signal that was higher than muscle on PDW TSE sequences. It was heterogeneous hyperintense on PDW TSE FS sequences. A subsequent arthroscopy revealed a cyclops lesion correlating with the MRI findings Cyclops lesion is a common postoperative lesion after ACL reconstruction. It is a heterogeneous mass of localized metaplasia composed of fibrous granulation tissue that forms anterior to the tibial tunnel (70,96) . Large lesions can project into the apex of the infrapatellar fat pad, restrict knee extension, and require surgical excision Localized anterior arthrofibrosis (cyclops lesion) is the second most common cause of extension loss after anterior cruciate ligament (ACL) reconstruction. We present and discuss two patients with prior ACL reconstructions, who presented with pain and loss of extension following surgery.

Benjamin Ma,3 Xiaojuan Li1 1Musculoskeletal Quantitative Imaging Research Group, Department of Radiology and Biomedical Imaging, University. At arthroscopy, the fibrous lesion has a headlike appearance with focal areas of discoloration that resemble an eye; thus, some refer to it as the cyclops lesion. On T1-weighted MR images, it appears as a focal nodular lesion of low signal intensity that is anterior to the graft in the intercondylar notch and can be indistinguishable from. Cyclops lesion may originate from a residual tibial ACL stump, a tibial tunnel trapdoor, infrapatellar fat pad metaplasia, intercondylar fibrosis, or the graft itself. Research shows evolution of the cyclops lesion progressing from early fibrosis to fibrocartilage. Tissues that may contribute to the formation of cyclops lesion include fibrous.

JBR-BTR. 2012;95 (5):336 An additional cause of limitation of extension in the ACL graft patient is the entity known as the Cyclops lesion. 7 This abnormality is due to the presence of nodular fibrous tissue that forms anterior to the distal ACL graft. It is so named because at arthroscopy, the nodular soft tissue is composed of a reddish structure that may have a.

The Pseudocyclops lesion, which is the torn graft located anteriorly in the intercondylar notch, can cause the same symptoms as a Cyclops lesion as it can cause a mechanical impingement, with loss of knee extension. In these cases, an MRI exam is important to exclude other complications and to diagnose the graft tear with ACL folding and.

Although the sensitivity and specificity of MR imaging for the cyclops lesion are yet to be determined, visualization of such fibrous tissue on MR images in a patient with clinical symptoms suggestive of localized anterior arthrofibrosis may be helpful in confirming the diagnosis From 2001 to 2006, the authors identified 10 patients (five women and five men, ages 27-76 years) with cyclops nodules seen at magnetic resonance (MR) imaging. All patients had a history of trauma but no history of ACL reconstruction.

It commonly results in gradual extension loss during the early postoperative course, and magnetic resonance imaging (MRI) of the soft tissue nodule attached to the ACL graft is needed. Cyclops lesions are easy to diagnose based on the symptoms and MRI findings

Currently known as a ramp lesion, this pathology has historically been under-recognized because it is commonly located within a posteromedial blind spot when using standard anterolateral and anteromedial arthroscopic portals. 41 This potential difficulty in diagnosis is clinically important as ramp lesions have been reported to be present.

Osteochondral lesions or osteochondritis dessicans can occur in any joint, but are most common in the knee and ankle. Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage.
