ABSTRACT
PURPOSE:
Poor scientific evidence exists on the issue of tourniquet application during total knee arthroplasty (TKA). It has been suggested that tourniquet application might improve interdigitation of the cement into the periprosthetic bones due to relatively dry surgical field. The hypothesis of the present study was that tourniquet use did not affect the periprosthetic bone cement penetration.METHODS:
The single-centre, randomized, controlled trial included 86 patients undergoing primary TKA (Clinical-Trials.gov NCT02475603). All patients meeting the inclusion criteria were randomly assigned to the tourniquet (n = 43) or non-tourniquet (n = 43) group after obtaining a written informed consent. The cumulative bone cement penetration was radiologically measured in AP (seven zones) and lateral views (three zones) as defined by Knee Society Scoring System. Further parameters such as perioperative blood loss, soft tissue swelling, pain level/analgesic consumption, operative time, length of hospital stay (LOS) and complication rate were statistically compared between the groups.RESULTS:
The cumulative bone cement penetration averaged 28.5 ± 1.7 mm in tourniquet versus 26.6 ± 1.6 mm in non-tourniquet groups (n.s.). The mean intraoperative blood loss was 250 ml higher in the non-tourniquet group (p = 0.0001). Patient-reported pre- to 6th-day post-operative reduction of the pain level was significantly higher in the non-tourniquet group (p = 0.003). The Morphine Equivalent Dose was higher in the Tourniquet group at discharge day (p = 0.02). Parameters such as total blood loss, soft tissue swelling, surgical time, LOS, and complication rates revealed similar results between the groups.CONCLUSIONS:
Tourniquet application did not influence the bone cement penetration significantly. Even though the intraoperative blood loss was reduced, the total blood loss was not affected significantly by tourniquet use. There was a tendency of higher post-operative pain and opioid analgesic requirement in the tourniquet group. LEVEL OF EVIDENCE I.Palabras clave
