We aimed to determine whether not using a tourniquet in cemented TKA would affect migration of the tibial component measured by radiosterometric analysis (RSA). Seventy patients were randomized into a tourniquet group and a non-tourniquet group and using model-based RSA, the migration of the tibial component was analyzed. Primary and secondary outcome measures were maximum total point motion (MTPM) and translations and rotations. Follow-up period was 2 years. The tibial component was well fixated in both groups and no significant difference in migration between the two groups was detected (P=0.632). Mean MTPM (SD) was 0.47 mm (0.16) in the tourniquet group and 0.45 mm (0.21) in the non-tourniquet group. Absence of tourniquet indicates that stable fixation of the tibial component can be achieved in cemented TKA.
我们旨在确定在骨水泥型全膝关节置换术（TKA）中不使用止血带是否会影响通过放射立体测量分析（RSA）测量的胫骨组件的移位。70例患者被随机分为止血带组和非止血带组，并使用基于模型的RSA分析胫骨组件的移位。主要和次要结局指标为最大总点运动（MTPM）以及平移和旋转。随访期为2年。两组的胫骨组件均固定良好，两组之间未检测到移位的显著差异（P = 0.632）。止血带组的平均MTPM（标准差）为0.47毫米（0.16），非止血带组为0.45毫米（0.21）。不使用止血带表明在骨水泥型TKA中可以实现胫骨组件的稳定固定。
