Abstract

Background: Currently, there exists a paucity of literature about the impact of prior knee arthroscopy on subsequent total knee arthroplasty (TKA). The purpose of this study was to compare outcomes of patients undergoing TKA after prior knee arthroscopy with a matched cohort of control subjects with primary osteoarthritis and no history of arthroscopy.

Methods: We reviewed patients who underwent primary TKA at our academic center from January 2011 to December 2017. Of these, we included 68 patients (70 knees) that were performed TKA following knee arthroscopy. The groups were split by sex, age to within 6 years, and body mass index within 5 kg/m. A 1:2 matching algorithm was applied. Outcome measures included surgical time, intraoperative estimated blood loss, Oxford Knee Score, range of movement, complications, and revision rate.

Results: This study had limited inclusion and exclusion criteria and a well-controlled intervention.

Conclusion: This clinical trial is expected to determine whether prior knee arthroscopy is associated with reduced functional outcomes or increased risks of revision and complications following TKA.

Trial registration: This study protocol was registered in Research Registry (researchregistry5413).
