Abstract
After anterior cruciate ligament (ACL) reconstruction surgery, achieving full range of motion and strength of the postoperative knee is critical for optimal surgical outcomes. Abnormal tissue growth and scar formation in the postoperative knee can create a block to terminal extension of the knee. Cyclops lesions are areas of granulation tissue with neovascularization and fibrous tissue formation peripherally, most commonly at the anterolateral aspect of the tibial graft site after ACL reconstruction. When these lesions block terminal extension and cause mechanical symptoms, cyclops syndrome is diagnosed, and secondary knee arthroscopy is often performed to remove this tissue to allow for full range of motion. This Technical Note describes a minimally invasive approach with the NanoScope. The NanoScope allows for decreased postoperative pain and swelling with a likely quicker recovery back to normal postoperative therapy.
