Injecting bioactive substances into the knee
is common in orthopaedic practice, and recently it has been shown
to mitigate risk factors for posttraumatic osteoarthritis.
Therefore, understanding the influence of these injections on
postoperative infection rate is imperative.
In conclusion, postinjury and preoperative
aspiration and CSI is a safe intervention that can be used before
ACLR. Future studies with larger sample sizes, longer patient
follow-ups, and multiple surgeons would be helpful to both better
understand infection risk and better identify the influence of CSI
on preventing posttraumatic osteoarthritis.
