Outcomes After 1-Stage Versus 2-Stage Revision Anterior Cruciate Ligament Reconstruction:

Background:Revision anterior cruciate ligament reconstruction (ACLR) is becoming increasingly common as the number of primary ACLR cases continues to rise. Despite this, there are limited data on the outcomes of revision ACLR and even less information specifically addressing the differences in 1-stage revision reconstruction versus those performed in a 2-stage fashion after primary reconstruction.Purpose:To compare the outcomes, patient satisfaction, and failure rates of 1-stage versus 2-stage revision ACLR.Study Design:Cohort study; Level of evidence, 3.Methods:All patients who underwent revision ACLR between 2010 and 2014 by a single surgeon were collected, and skeletally mature patients over the age of 17 years were included. Patients were excluded if they were skeletally immature; had a previous intra-articular infection in the ipsilateral knee; underwent a prior alignment correction procedure, cartilage repair or transplant procedure, or meniscal allograft transplantation; or had an intra-articular f...
