Is There a Correlation Between Surgical Technique for Primary Anterior Cruciate Ligament Surgery and the Risk of Subsequent Formation of Fibrous Cyst (Cyclops) in the Knee Joint, Which Leads to the Need for Surgical Removal of the Cyclops?

Completed

• Conditions: Cyclop Arthrofibrosis Anterior Cruciate Ligament

• Registration Number: NCT05301686
• Lead Sponsor: Aarhus University Hospital

Brief 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.
