Abstract
Revision anterior cruciate ligament (ACL) reconstruction typically has worse outcomes
than primary reconstructions. Minimal long-term data exist regarding 5-year results.
We chose to perform a systematic review to evaluate midterm (5-year) revision ACL
reconstruction outcomes (patient-reported outcomes, reoperation, stability, arthritis)
in comparison to primary ACL reconstructions at similar time points. Embase, Cochrane,
and PubMed databases were queried, and four studies met the inclusion criteria. Two
authors reviewed and performed data extraction. All were level 4 studies. Review of
the studies demonstrated that results at 5 years are consistently worse than those
noted in primary reconstructions for objective and patient-reported outcomes. Revision
ACL reconstruction outcomes remain worse than primary reconstructions at midterm 5-year
follow-up. The level of evidence is 4.
