In general, an inciting trauma, surgery, or infection results in a healing response which includes the migration of inflammatory cells and the proliferation of fibroblasts followed by the release of cytokines, growth factors, and reactive oxygen and nitrogen species.1 Failure to terminate the healing response normally results in persistent inflammation of the synovial tissue with increased inflammatory cytokines and certain growth factors that trigger tissue fibrosis via the transformation of fibroblasts.1 Fibroblast proliferation results in the accumulation of increased extracellular matrix which impairs blood flow and results in local hypoxia. The only case reported previously was by Rubin et al following bone-patellar tendon-bone ACL reconstruction.2. You are viewing 1 of your 2 free articles.

An ACL reconstruction was performed ten weeks after the original injury. 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. If a cyclops lesion is suspected, you will need to return to your orthopaedic surgeon and likely have an MRI to confirm the presence of the scar tissue. 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.
