A Cohort Study of Non-surgical Treatment and Exercise Rehabilitation in Patients With Anterior Cruciate Ligament Rupture

This clinical trial compared the prognosis of surgical and non-surgical treatment in patients with complete anterior cruciate ligament rupture

Anterior cruciate ligament injury is a common neuromuscular injury to the knee joint. The incidence rate is gradually increasing. There are 400,000 ACL reconstruction operations in the United States every year. The population of my country is equivalent to 4.3 times that of the United States. The potential economic burden of cruciate ligament reconstruction surgery on the country cannot be ignored. Anterior cruciate ligament reconstruction is seen as an effective treatment for this disease, avoiding secondary meniscus damage and knee degeneration, but the failure rate is still as high as 20%. In addition, problems such as poor bending angle caused by postoperative adhesions that may occur after surgery, atrophy of the quadriceps muscle of the patient's affected leg, and overstrain of the healthy leg caused by psychological factors may affect the quality of life after surgery. Reasons that prevent return to sports. 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.

Some 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. Individual differentiated treatment is necessary.
