A notchplasty was performed following debridement of the lesion from the 9 oclock to the 1 oclock position. The odds ratio of 0.6 tends to show that ACL reconstruction with residual resection has a slightly higher risk of a cyclops lesion in the postoperative course. Cyclops lesions can be found in up to 25% of ACL reconstructions at 6 months after surgery. This may be due to a what is termed a Cyclops Lesion. Yet, clinicians often prescribe pain-free exercise. Many of these lesions may go undiagnosed as they do not all present symptomatically.

After surgery, working with a physical therapist will be helpful to guide you with exercises and advice to achieve this. Sagittal T2-weighted (5A) and axial fat-suppressed proton density-weighted (5B) images demonstrate a 5 mm intra-articular chondral body (arrows) surrounded by joint fluid anterior to the ACL graft. Quadriceps grafts were found to have a higher risk than hamstring, which may have been related to the bundle size (. Disclaimer.

For those not familiar, a cyclops lesion is a wad of scar tissue in the anterior aspect of the knee joint. Poor regain of knee extension in both terms of speed and range. Early pool work also provides hydrostatic pressure to aid with effusion drainage. Patients may present with decreased range of motion in flexion and extension. Clinical evaluation is the mainstay in establishing the diagnosis of arthrofibrosis, however MRI plays an important role in establishing the extent of involvement by fibrosis and to exclude other complications that may have a similar clinical presentation. Epub 2020 Jun 2. In 13 patients without cyclops lesions, the femoral tunnel entered the notch within 2 mm of the intersection of the intercondylar roof and the posterior femoral cortex.
