The Kinematic rotating hinge offers a solution as a salvage procedure for severely deformed and unstable "end-stage" knees. Excellent short-term results in terms of pain relief can be achieved, and motion up to 130 degrees is possible, depending on the condition of the quadriceps mechanism and the extent of scarring from previous operations. Care must be taken to avoid cortical penetration, especially in cases of hinge revisions, osteoporosis, thin-walled bones, and the presence of old cement. As with any total knee arthroplasty, care must be taken to achieve optimal rotatory alignment of the tibia beneath the femur to guarantee good patellar tracking.
运动旋转铰链为严重畸形和不稳定的“终末期”膝关节提供了一种挽救手术方案。在缓解疼痛方面可取得优异的短期效果，根据股四头肌机制的状况和既往手术的瘢痕形成程度，可实现高达130度的活动度。必须注意避免穿透皮质骨，尤其是在铰链翻修、骨质疏松、骨壁薄以及存在陈旧骨水泥的情况下。与任何全膝关节置换术一样，必须注意使胫骨在股骨下方达到最佳旋转对线，以确保髌骨轨迹良好。
