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.

Detailed description

Initial assessments will be conducted preoperatively. The follow-up examination will take place during the first 7 days following surgery and then at 21 days (D21), 45 days (D45), and 5 months postoperatively.

Interventions

PROCEDUREACL reconstruction with a dual-flow arthroscopy sheath

ACL reconstruction will be performed by the surgeon without a tourniquet but using a dual-flow arthroscopy sheath.

PROCEDUREACL reconstruction with a thigh tourniquet

ACL reconstruction will be performed by the surgeon using a thight tourniquet

Design outcomes

Primary

MeasureTime frameDescription
Postoperative pain intensity according to a Numeric Rating Scale (NRS)4 days after surgeryPain 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.

Secondary

MeasureTime frameDescription
Pain intensity according to a Numeric Rating Scale (NRS)Up to 3 days after surgeryPain intensity will be assessed using a Numeric Rating Scale (NRS) on the day of surgery (preoperatively and at 4, 12, and 16 hours postoperatively) and on days 1, 2, and 3 following surgery (at 8 AM, 12 PM, and 8 PM). The minimum value of the scale, corresponding to no pain at all, is 0 and the maximum value is 10.
Total antalgic consumptionUp to 4 days after surgeryTotal antalgic consumption will be assessed in number of doses per type of drug, from surgery up to 4 days after surgery.
Arthrogenic Muscle Inhibition (AMI) classificationPreoperative, on Day 0 before and after surgery and then on Day 21 and Day 45 after surgery.This classification is used to assess quadriceps contraction.
Lysholm knee scoring scalePreoperative, Day 21, Day 45 and Month 5 after surgeryThe Lysholm Knee Score is a standardized questionnaire used to assess knee function after surgery. The total score obtained ranges from 0 to 100. The higher the score, the better the knee's function.
Knee Blessure and Osteoarthritis Outcomescore (KOOS)Preoperative, Day 21, Day 45 and Month 5 after surgeryThe KOOS is a self-administered questionnaire that evaluates multiple aspects of knee health, including pain, symptoms, daily living activities, sports and recreation function, and quality of life. Each subscale is rated from 0 to 100, where 0 represents extreme problems and 100 represents no problem.
Knee mobilityPreoperative, Day 21, Day 45 and Month 5 after surgeryKnee mobility will be assessed using a goniometer.
Total surgical timeDay 0Assessed in minutes
Arthroscopic timeDuring procedureAssessed in minutes
Intraoperative visibilityDuring procedureIntraoperative visibility will be assessed by the surgeon using a 4-point scale (excellent, good, fair, poor).
Thigh, knee and calf diameters in cmPreoperative and Day 21Diameters will be evaluated in cm.
CPK blood levelPreoperative and Day 1
Hemoglobin levelPreoperative, Day 1 and Day 7
Presence of complicationsUp to 5 monthsThe number and type of complications will be recorded, including hematomas, knee stiffness, deep vein thrombosis, complex regional pain syndrome, deep infection, superficial infection, and recurrent anterior cruciate ligament graft rupture.
Muscle strengthPreoperative and 5 monthsMuscle strength will be assessed in both limbs using isokinetic testing
