Abstract
Two-stage revision anterior cruciate ligament (ACL) reconstruction is an effective
way to revise suboptimal tunnel-placement allowing for proper graft fixation. However,
prolonged increased laxity of the knee may increase the risk of meniscal or chondral
injury. It was hypothesized that no additional meniscal or chondral lesions occur
in between the two stages of the two-stage revision ACL reconstruction. In this retrospective
study, 42 patients undergoing a two-stage revision ACL reconstruction were included.
Surgical notes for both stages were screened for meniscal and chondral status, interventions
to any concurrent injury, surgery dates, along with basic patient characteristics.
In 4 of the 42 patients, a new meniscal tear occurred in between the two stages, of
which three required partial meniscectomy during the second stage of the ACL revision.
One patient experienced a new small degenerative tear that did not require intervention.
Two out of the four menisci that were repaired during the first stage had failed and
required partial meniscectomy. No significant difference was found in the time between
the two stages with respect to the occurrence of meniscal tears. No significant differences
in chondral status were found. In conclusion, approximately 10% of patients developed
a new meniscal tear and no difference in macroscopic chondral injury was observed
between the first and second stages.
