摘　　要：目的评估改良自动液压膝关节撑开器在全膝关节置换中韧带平衡的作用。方法分析改良自动液压膝关节撑开器对全膝关节置换中韧带平衡的生物力学行为的影响,获取相关的信息。结果液压撑开器将可作为撑开-感应装置,在伸直位下的下肢力线重建、膝关节屈伸位的矩形等距间隙的调整、内外侧间隔力的平衡、决定韧带松解和股骨假体的旋转对位等方面提供定量的信息。结论自动液压撑开器有助于外科医生在全膝关节置换的韧带平衡时精确地进行操作。Objective To investigate a modified robotized hydraulic tensor for management of the ligament balance in the total knee arthroplasty. Methods The effect of the modified robotized hydraulic tensor on the mechanical behaviour of the ligament system balance in the total knee arthroplasty was analyzed and the related information was obtained. Results The robotized hydraulic tensor acted as a tensor-sensor system, which could assist the surgeon by providing the quantitative information to align the lower limb in extension, equalize the articular spaces in extension and flexion, balance the internal and external forces, and define the femoral component rotation, and by providing the information to plan the releasing of the soft tissues and the rotating of the femoral component. Conclusion The modified robotized hydraulic tensor can enable the surgeon to properly manage the ligament balance in the total knee arthroplasty.
