Protocol and descriptive epidemiology of the SIGASCOT Italian multicentric registry of revision ACL reconstruction: a 1-year pilot study

The aim of the present study was to present the demographic and baseline results of the first year of course of the SIGASCOT Italian registry of Revision ACL reconstruction.The data of the patients undergoing revision ACL reconstruction, enrolled in by 20 SIGASCOT members from March 2015 to May 2016, were extracted from the Surgical Outcome System (SOS). Overall, 126 patients were enrolled; 18 were excluded due to incomplete data. Mean age at surgery was 30.4 ± 9.3 years (median 29; 23-38), mean BMI was 22.6 ± 2.3 kg/m2 and 77% were males. Revision was performed with a single-bundle technique in 94%, using allograft in 57% of cases and autograft in 43%. Only 28% had both menisci intact, and meniscal repair or replacement was performed in 25% of patients for medial meniscus and 8% for lateral meniscus. During the first year of enrollment, the SIGASCOT Italian ACL revision registry was able to collect the data of more than 100 patients. The revision ACL reconstruction was usually performed with a single-bundle technique, using allograft and autograft almost in the same extent.
