Medial meniscal and chondral pathology at the time of revision anterior cruciate ligament reconstruction results in inferior mid-term patient-reported outcomes Academic Article uri icon

abstract

  • Anterior cruciate ligament (ACL) injuries are frequently not isolated injuries and damage to the menisci and articular cartilage surfaces is common. The concomitant presence of meniscal and chondral damage has the potential to influence patient outcomes following ACL reconstruction surgery and especially following revision ACL reconstruction where these findings are more common. However, study results regarding the mid-term outcome have been inconsistent. The purpose of this study was to compare mid-term patient-reported outcomes and return to sport in patients with and without meniscal and chondral pathology at the time of revision ACL reconstruction surgery.A cohort of 180 patients (131 males, 49 female) with a mean age of 25.3 (SD 7.8) years participated at an average follow-up time of 4.6 (SD 1.3) years after revision ACL reconstruction surgery. All patients completed the IKDC Subjective, Marx Activity, KOOS-Quality of Life (QOL) and Single Numerical Assessment (SANE) scores. In addition, patients were asked to indicate the highest level of sport to which they had returned following their revision surgery. Any further injuries to either knee were also documented. Patients were grouped according to whether or not they had medial or lateral meniscal pathology at the time of revision surgery; and whether or not they had > 50% depth chondral damage (ICRS 3 or 4). All outcomes were compared between these groupings.Patients with medial meniscal pathology had significantly lower Marx, KOOS-QOL and SANE scores than patients without. There were no differences in any outcome score between patients with and without lateral meniscal pathology. Patients with ICRS 3 or 4 chondral pathology had significantly lower scores on all patient-reported outcomes as well as a lower rate of return to the same level of pre-injury sport.The presence of more severe chondral damage at the time of revision ACL reconstruction has a negative impact on functional outcomes, activity levels and return to sport rates. In addition, the presence of medial meniscal pathology was associated with significantly lower functional and quality of life scores than patients without pathology. These findings provide important clinically relevant data on the outcomes following revision ACL reconstruction with concomitant chondral and meniscal injury.III.
