Delayed anterior cruciate ligament reconstruction increases the risk of abnormal pre-reconstruction laxity, cartilage and medial meniscus injuries
Arthroscopy Nov 26, 2020
Cristiani R, Janarv PM, EngstrÖm B, et al. - In this study, the relationship between a delay in anterior cruciate ligament reconstruction (ACLR), age, gender, body mass index (BMI) and cartilage injuries, meniscus injuries, meniscus repair, and abnormal pre-reconstruction laxity was ascertained. Between January 2005 and March 2017, individuals who had undergone primary ACLR at the institution, with no correlated ligament injuries, were distinguished. Researchers applied logistic regression analyses to assess if a delay in ACLR, age, gender, and BMI were risk factors for cartilage and meniscus injuries, meniscus repair, and abnormal (side-to-side difference > 5 mm) pre-reconstruction laxity. This study included a sum of 3,976 patients (mean age 28.6 ± 10.6 years, range 10-61 years). While a delay of > 6 months increased the risk of abnormal pre-reconstruction laxity and reduced the likelihood of medial meniscus (MM) repair, a delay in ACLR of > 12 months elevated the risk of cartilage and MM injuries. Moreover, ACLR should be conducted within 6 months after the injury to decrease meniscus loss and the risk of jeopardizing knee laxity.
