Abstract
Computer-assisted surgery (CAS) in total knee arthroplasty (TKA) could be useful in reducing the overall blood loss. A prospective randomised study was performed with two groups of 50 patients each of whom were treated for knee arthritis. Patients of group A were treated by a conventional standard procedure, while for patients of group B a specific CAS procedure was used. We determined the intraoperative blood loss according to the Orthopaedic Surgery Transfusion Haemoglobin European Overview (OSTHEO) study. The average blood loss in patients of group A was 1,974 ml (range: 450-3,930 ml) compared to 1,677 ml of patients of group B (range: 500-2,634 ml). A statistically significant difference was found between the two groups (p = 0.0283). Computer-assisted surgery is highly recommended in TKR to save blood. It creates more possibilities to operate on anaemic patients and subjects who cannot accept blood products by reducing blood loss risk.
摘要
计算机辅助手术（CAS）在全膝关节置换术（TKA）中可有助于减少总体失血量。我们进行了一项前瞻性随机研究，共纳入了两组各 50 例膝关节关节炎患者。A 组患者采用常规标准手术治疗，B 组患者采用特定的 CAS 手术治疗。我们根据《矫形外科输血血红蛋白欧洲概览（OSTHEO）研究》来确定术中失血量。A 组患者的平均失血量为 1974ml（范围：450-3930ml），而 B 组患者的平均失血量为 1677ml（范围：500-2634ml）。两组间存在统计学显著差异（p=0.0283）。计算机辅助手术在 TKR 中强烈推荐使用，以节约血液。它通过降低失血风险，为贫血患者和不能接受血液制品的患者创造了更多的手术机会。
