Different total knee arthroplasty (TKA) implants were created for the treatment of severe symptomatic gonarthrosis and Medial Pivot TKA (MP TKA) seem to reproduce the normal kinematics of the knee. We compare two different prosthetic designs of MP TKA in order to identify whether there is a difference between the two in terms of degree of patient satisfaction. Methods: A total of 89 patients were analyzed. A group of 46 patients who benefited from a TKA with the Evolution® prosthesis and one of 43 patients who received a TKA with the Persona® prosthesis. KSS, OKS, FJS and the ROM were analyzed at follow up.
The values of KSS and OKS were similar between the two groups (p>0,05). Our statistical analysis revealed a statistically significant increase (p <0.05) in ROM in the Persona® group and in FJS in the Evolution® group. No radiolucent lines were observed in both groups at the radiological final follow-up. Conclusions: MP TKA models analysed are a valuable tool to achieve satisfactory clinical outcomes. This study demonstrates that the FJS is an important score for the evaluation of patient's satisfaction: a ROM's limitation can be accepted by the patient in exchange for a more natural perceived knee.
不同的全膝关节置换（TKA）植入物被用于治疗严重的症状性膝关节骨关节炎，内侧旋转平台膝关节置换（MP TKA）似乎可以复制膝关节的正常运动学。我们比较了两种不同的 MP TKA 假体设计，以确定两种假体在患者满意度方面是否存在差异。方法：分析了 89 例患者。一组 46 例患者受益于 Evolution®假体的 TKA，另一组 43 例患者受益于 Persona®假体的 TKA。在随访时分析 KSS、OKS、FJS 和 ROM。结果：两组的 KSS 和 OKS 值相似（p>0.05）。我们的统计分析显示，Persona®组的 ROM 和 Evolution®组的 FJS 均有统计学显著增加（p<0.05）。在放射学最终随访时，两组均未观察到放射性透亮线。结论：分析的 MP TKA 模型是获得满意临床结果的有价值工具。本研究表明，FJS 是评估患者满意度的重要指标：患者可以接受 ROM 限制，以换取更自然的膝关节感知。
