The use of conservative treatment instead of surgery after recent ACL injury has received high attention, and a large number of RCTs have compared the benefits of surgery and conservative treatment.\n\nSome reviews pointed out that the clinical outcomes of surgical treatment and conservative treatment are not much different, and even questioned the prognosis after anterior cruciate ligament reconstruction.
