Rotating hinge prosthesis knee replacement for the treatment of malignant bone tumors around the knee / 中国矫形外科杂志

ABSTRACT

[Objective]To study the operative methods and effects of limb salvage with rotating hinge prosthesis replacement for malignant tumors around the knee.[Method]Limb salvage surgery with rotating hinge prosthesis replacement were performed in 14 patients with malignant bone tumors around the knee.There were 9 cases in distal femoral,5 cases in proximal tibia.[Result]Forteen patients were followed up for 17~65 months(averaged,4 months).The satisfactory rates were 85.7%,the extension and flexion spheres of knee activity were respectively 0? and 90?~130?(averaged,110?).There was recurrence in one patient after operation,infection one;prosthetic loosening one.[Conclusion]Application of rotating hinge prosthesis knee replacement in limb salvage treatment of malignant tumor around the knee is an effect method.It is an effect method for the treatment of malignant tumor of the knee by using rotating hinge prosthesis.It can decrease the strength of the bone-prosthetic and the incidence of the occurrence of fatigue fracture and the loosening of prosthetic.
