国产T-Free假体行全膝关节表面置换临床疗效

摘要

目的：评价应用国产T-Free假体行人工全膝关节表面置换术( TKA)的临床疗效。方法采用国产T-Free假体(后稳定固定平台型假体,PS型)行TKA治疗39例膝骨关节炎、类风湿关节炎患者(41膝)。按HSS评分标准进行膝关节疼痛、关节活动度、畸形三方面的评价。结果39例均获得随访,时间12~30个月。膝关节功能HSS评分术前为(39．1±8．5)分,术后12个月为(89．2±10．8)分,差异有统计学意义(P<0．05)。结论应用国产T-Free假体行TKA能纠正患者下肢屈曲、力线畸形,消除行走疼痛,减少伸膝受限,重建膝关节稳定性,具备高屈曲度功能,近期疗效显著。%Objective To evaluate the clinical effect of the application of domestic T-Free prosthesis in the treatment of total knee arthroplasty( TKA) . Methods A total of 39 patients with knee osteoarthritis and rheumatoid arthritis (41 knees) were treated with domestic spring T-Free prosthesis (posterior stable fixed platform prosthesis, type PS), knee joint pain, joint mobility and deformity were evaluated according to HSS score criterion. Results All 39 pa-tients were followed up for 12 ~30 months. The HSS score was ( 39. 1 ± 8. 5 ) points preoperatively and ( 89. 2 ± 10. 8) points in the 12th month postoperatively, and the difference was statistically significant (P<0. 05). Conclu-sions The application of domestic T-Free prosthesis for TKA can correct patients with lower limb flexion, lines of force deformity, eliminate walking pain, decrease in the extensor of knee joint, reconstruct the knee joint stability, with high bending curvature function, significant efficacy.
