Summary

Fibrous scar tissue formation (Cyclops) after a primary anterior cruciate ligament reconstruction (ACLr) may affect patients' ability to perform work and exercise to such an extent that further arthroscopic surgery may be necessary. The purpose of the study is to estimate the 2-year incidence of removal of cyclops lesion after ACLr for a cohort of approximal 3000 patients operated at Aarhus University Hospital in the period 2005-2019. Specifically, change in surgical technique and graft choice will be analyzed.
