A risk-benefit analysis of alternating low-pressure CO2 insufflation and fluid medium in arthroscopic knee ACL reconstruction
Knee Surg Sports Traumatol Arthrosc. 2014 Jul;22(7):1483-90Ninety four patients undergoing anterior cruciate ligament (ACL) reconstruction were randomized to evaluate the safety and efficacy of low-pressure CO2 knee joint insufflation as compared to conventional fluid-based distention. Patients were monitored over 6 months. The evidence presented in this trial revealed no significant difference between the CO2-based ACLR and the conventional ACLR based on end-tidal CO2 (EtCO2) and other monitored data. Tourniquet time was significantly shorter in the gas group, while complications and IKDC scores were comparable between groups.
