Tourniquet use during total knee arthroplasty does not offer significant benefit: A retrospective cohort study

WOS: 000357389300022PubMed ID: 25917205Introduction: Tourniquets are routinely employed during total knee arthroplasty; however, their use remains controversial. Methods: This study investigates the efficacy and safety of this practice. A retrospective analysis of 186 patients was performed to assess benefits and/or risks associated with tourniquet use during knee arthroplasty. Total knee arthroplasty was performed using the Biomet Vanguard (R) PCL Prosthesis (Biomet, Warsaw, IN, USA). In total, 126 patients who had undergone total knee arthroplasty were included in our final analysis. Results: Patients with tourniquets had significantly less intraoperative blood loss than patients without (P < .001); patients without tourniquets required more blood transfusions (P = .551), and had significantly longer surgical times (P = .011). However, patients with tourniquets had more postoperative blood loss (P < .001), longer hospital stays (P = .013), and more frequent complications (P = .571). Blood transfusion requirement was significantly associated with complications (P < .001). Conclusions: Tourniquet use provided no overall benefit

Aggresive Aneurysmal Bone Cyst Two Case Report

Two cases of an aggresive aneurysmal bone cyst that involved the distal femur and forearm in 20-year-old men were presented. The recurrence of the aggressive aneurysmal bone cyst with severe infection in the femur in spite of total excision caused deterioration of the extremity circulation. Hip disarticulation was applied for the treatment. The second case with an alytic expansile lesion involving the 2/3 of the right ulna was surgically treated by total excision and reconstruction of the ulna by using the ipsilateral fibula. At the 2-year follow-up, the patient had complete incorporation of the fibular graft. The differential diagnosis of the aneurysmal bone cyst from the local aggressive and malignant tumor and different treatment options were discussed with the literature
