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.

|---|---|---|---|
| non-surgical treatment | Experimental | The patient who was diagnosed with complete rupture of the ACL in the Institute of Sports Medicine of the Third Hospital of Peking University was informed by the doctor that there is a chance that the ACL may grow back after 6 weeks of strict bracing. |
|
| surgical treatment | Active Comparator | The patient who was diagnosed with complete rupture of the ACL in the Institute of Sports Medicine of the Third Hospital of Peking University was informed by the doctor that there is a chance that after 6 weeks of strict brace immobilization, the ACL may grow back without surgery. However, the choice was still made for immediate ACL reconstruction. This group of patients underwent anterior cruciate ligament reconstruction surgery in the Third Hospital of Peking University. |

| non surgical treatment | Procedure | Conservative treatment is required to use a curved splint for 6 weeks to keep the feet on the ground, bathing and sleeping without loosening the utensils and taking no steroids during the period. Physical examination and magnetic resonance imaging were performed after 6 weeks. If laxity remained unsatisfactory, the outcome was recorded as failure and surgery was changed. |

| Knee Outcome Survey Activities of Daily Living (KOS-ADLS) Scale | The ADLS is a 14 item scale that queries patients about how their knee symptoms effect their ability to perform general daily activities (6 items) as well as how their knee condition effects their ability to perform specific functional tasks (8 items).

The scores of all items are summed, divided by 70, then multiplied by 100 to give an overall ADLS percent rating. Higher percentages reflect higher levels of functional ability.
