After a ligament in the knee a lot of the time surgery is inevitable however its nice to know the likely hood of complications. The data suggests that the total rate of complications after an ACL reconstruction was 39%, and the surgical revision rate for any reason was 28%. Problems with the hardware material were more frequent in the hamstring group, leading to an increased rate of surgical revision. Anterior knee pain was initially higher in the patellar tendon group, but there was no significant difference in a 2-year interval. The rerupture rate was statistically higher in the hamstring group.
39% is a high figure so always rushing to surgery is not always the best way to go, however ACL injuries do need to be assed very carefully so that the right form of rehab or surgery is done.
