Brief Summary
This is a prospective randomized study comparing tourniquet use versus a dual-flow arthroscopy sheath in Anterior Cruciate Ligament (ACL) reconstruction surgery. The ACL is largely responsible for knee stability and contributes to central pivot with the posterior cruciate ligament. ACL rupture is associated with a violent twisting motion of the knee, which is usually irreparable without surgical intervention. ACL reconstruction via arthroscopy is the gold standard treatment for young, active patients with knee instability. Reconstruction is commonly performed using a thigh tourniquet to improve intraoperative visibility, reduce bleeding, and shorten procedure time. However, numerous studies associate tourniquet use with an increased risk of postoperative complications such as increased pain, muscle injury, postoperative bleeding, and deep vein thrombosis. Therefore, it seems relevant to conduct further investigations into the benefits of new methods to replace tourniquet. In this context, the dual-flow arthroscopy sheath could improve postoperative recovery after ACL reconstruction and could limit the risk of complications, thus improving ambulatory care for patients. This study propose to compare two groups of patients undergoing ACL reconstruction: those operated on with a tourniquet versus those operated on using the dual-flow arthroscopy sheath.

Outcome Measures
Primary Outcomes (1)
Postoperative pain intensity according to a Numeric Rating Scale (NRS)
Pain intensity will be assessed using a Numeric Rating Scale (NRS) at 8 AM, 12 PM, and 8 PM on postoperative day 4. The minimum value of the scale, corresponding to no pain at all, is 0 and the maximum value is 10.
4 days after surgery
Secondary Outcomes (14)
Pain intensity according to a Numeric Rating Scale (NRS)
Up to 3 days after surgery
Total antalgic consumption
Up to 4 days after surgery
Arthrogenic Muscle Inhibition (AMI) classification
Preoperative, on Day 0 before and after surgery and then on Day 21 and Day 45 after surgery.
Lysholm knee scoring scale
Preoperative, Day 21, Day 45 and Month 5 after surgery
Knee Blessure and Osteoarthritis Outcomescore (KOOS)
Preoperative, Day 21, Day 45 and Month 5 after surgery
- +9 more secondary outcomes
Study Arms (2)
Dual-flow arthroscopy sheath
EXPERIMENTALPatients will undergo ACL reconstruction using a dual-flow arthroscopy sheath.
Thigh tourniquet
ACTIVE COMPARATORPatients will undergo ACL reconstruction using a thigh tourniquet.
Interventions
ACL reconstruction will be performed by the surgeon using a thight tourniquet
