The aim of this study was to test our hypothesis that delayed surgical treatment of patients with ACL tears, especially those with high Tegner activity levels, results in more severe and complicated meniscal and osteochondral lesions with potential affect on the outcome. Methods: This study included 385 patients who underwent arthroscopic ACL reconstruction between 2001 and 2009. Patients' arthroscopic video records or MRI scans and patient files at the time of surgery were analyzed. We defined severe meniscal and osteochondral lesions which could negatively affect the outcome and labeled them meniscal lesions affecting outcome (MLAO) and osteochondral lesions affecting outcome (OLAO). The relation between MLAO, OLAO, time since injury and Tegner activity levels were statistically analyzed. Results: The incidences of MLAO and OLAO grew statistically higher as time elapsed between the injury and surgery increased (p=0.001, p<0.05; p=0.001, p<0.05). The relation between the Tegner activity score, MLAO and OLAO risk were found to be statistically insignificant (p=0.317, p=0.184, p>005). Conclusion: Delays in ACL reconstruction surgery result in an increase in the incidence of meniscal and osteochondral lesions which have the potential to negatively affect the surgical outcome.eninfo:eu-repo/semantics/openAccessOrthopedicsACL reconstructionMeniscal lesionOsteochondral lesionTegner activity levelDeficient kneeTearsTimeInsufficiencyInjuryRiskAdolescentAdultAge distributionAnterior cruciate ligamentAnterior cruciate ligament reconstructionArthroscopyCohort studiesFemaleFollow-up studiesHumansIncidenceKnee injuriesMaleMenisci, tibialMiddle agedOsteochondritisPostoperative complicationsRetrospective studiesRisk assessmentSex distributionStatistics, nonparametricTime factorsTreatment outcomeYoung adultArticle0002087133000102-s2.0-8005511519934835245522032992OrthopedicsAnterior Cruciate Ligament Reconstruction; Hamstring Tendons; Return to SportAdolescentAdultAge distributionAnterior cruciate ligamentAnterior cruciate ligament reconstructionArthroscopyArticleCohort analysisComparative studyFemaleFollow upHumanIncidenceInjuryKnee injuryKnee meniscusMaleMethodologyMiddle agedNonparametric testOsteochondritisPathologyPostoperative complicationRetrospective studyRisk assessmentSex ratioTimeTreatment outcome
