Abstract：
UNASSIGNED: The results of primary total knee replacement (TKR) using hinge implants performed in the Indian population with post-polio residual paresis (PPRP) are unknown. The purpose of this study was to report the outcome of primary rotating hinge TKR in Indian patients with PPRP at a minimum follow-up of 12 months.
UNASSIGNED: We retrospectively reviewed the clinical and radiological records of six patients treated with primary rotating hinge TKR. Pre-and post-operative (at final follow-up) knee range of motion (ROM), knee sagittal deformity, knee society score (KSS), and Oxford knee score (OKS) were compared to determine improvement in function.
UNASSIGNED: Six rotating hinge TKRs (five female and one male patient) were analyzed for this study. At a mean follow-up of 27 ± 22 months (range, 12-71 months), the mean pre-operative KSS of 50.6 ± 2.5 significantly improved (P < 0.0001) to 72.5 ± 1.6, and the mean pre-operative OKS of 23.6 ± 1.6 significantly improved (P < 0.0001) to 35.3 ± 1.7. The mean pre-operative knee ROM of 94° ± 10° changed to 92° ± 4° (P = 0.64) and the mean pre-operative sagittal deformity of 7° ± 23.5° changed to -3° ± 2.5° (P = 0.32) at final follow-up. None of the knees had any intra- or post-operative complications or showed radiologic evidence of post-operative loosening, subsidence, or periprosthetic radiolucent lines at the final follow-up.
UNASSIGNED: Rotating hinge TKR gave excellent clinical and radiological results at a mean follow-up of 27 months in the present study. Despite TKR being a technically challenging procedure in patients with poliomyelitis-affected limbs, a rotating hinge design, along with meticulous surgical technique, can significantly improve function in such patients.

摘要：
■在患有脊髓灰质炎后残留轻瘫（PPRP）的印度人群中使用铰链植入物进行初次全膝关节置换（TKR）的结果未知。这项研究的目的是报告印度PPRP患者的主要旋转铰链TKR的至少12个月随访结果。
■我们回顾性回顾了6例接受原发性旋转铰链TKR治疗的患者的临床和影像学记录。术前和术后（最终随访时）膝关节活动范围（ROM），膝关节矢状畸形,膝盖社会得分（KSS），和牛津膝关节评分（OKS）进行比较，以确定功能的改善。
■本研究分析了六个旋转铰链TKR（五名女性和一名男性患者）。平均随访27±22个月(范围，12-71个月），术前平均KSS(50.6±2.5)显著改善(P<0.0001)至72.5±1.6,术前平均OKS(23.6±1.6)显著改善(P<0.0001)至35.3±1.7。最终随访时，术前平均膝关节ROM94°±10°变为92°±4°(P=0.64)，术前平均矢状畸形7°±23.5°变为-3°±2.5°(P=0.32)。膝关节无任何术中或术后并发症，或显示术后松动的放射学证据，沉降,或最终随访时的假体周围射线可透线。
■旋转铰链TKR在本研究中平均随访27个月时获得了出色的临床和放射学结果。尽管TKR在患有脊髓灰质炎的四肢患者中是一项技术上具有挑战性的手术，旋转铰链设计，加上细致的手术技术，可以显著改善此类患者的功能。
