To report 10-year outcomes and survivorship in patients undergoing bicompartmental knee arthroplasty (BCKA) using the Journey-Deuce prosthesis in a consecutive prospective case series.
Between November 2006 and November 2009, 41 patients with a mean age of 69.6 years (range 51-86) underwent 51 bicompartmental knee arthroplasties with the Journey-Deuce knee prosthesis. All patients presented with symptomatic medial and patellofemoral compartment osteoarthritis, with intact cruciate ligaments and a preserved lateral compartment on plain radiographs and Magnetic Resonance Imaging. Clinical assessment was undertaken pre-surgery and at 1, 2, 5 and 10 years post-surgery using the Oxford Knee Score (OKS), EuroQol Group 5-Dimension self-reported questionnaire (EQ-5D) and maximal active range of motion (ROM).
30 patients (37 knees) were followed-up at a mean time of 11.4 years (SD 1.1; range 10.5-14.0). Eight patients (ten knees) were deceased and three could not be contacted at final review. No major component revision was performed. Pre-operative OKS 25.4 (SD 5.2; range 15-40), knee flexion 116.4° (SD 10.3°; range 100°-140°) and EQ-5D 70.5 (SD 19.9; range 25-95). 10-year OKS 43.5 (SD 4.1; range 32-48), knee flexion 127.3° (SD 11.1°; range 105°-144°) and EQ-5D 77.4 (SD 9.3; range 60-100). The OKS (p < 0.0001), EQ-5D (p = 0.024) and active knee flexion ROM (p < 0.0001) all significantly improved from pre-surgery to 1-year post-surgery, with no further significant changes in these scores between any post-operative time period up until 10 years. 32% (7/22) of tibial and 45% (10/22) of femoral components showed progressive radiolucencies between 2 and 5-year and 10-year follow-up.
This is the largest cohort of patients having undergone BCKA (with the Journey-Deuce prosthesis) with longest follow-up described in the literature. At 10 years, patients presented with significantly improved clinical outcomes, comparable to other surgical arthroplasty options. No major component revision was performed. Progressive radiolucencies were noted in 32% of tibial and 45% of femoral components without corresponding clinical signs of loosening.
Level III.
报告使用 Journey-Deuce 假体进行双间室膝关节置换术（BCKA）的 10 年结果和生存率，这是一项连续前瞻性病例系列研究。
2006 年 11 月至 2009 年 11 月，41 例平均年龄 69.6 岁（51-86 岁）的患者接受了 51 例双间室膝关节置换术，使用 Journey-Deuce 膝关节假体。所有患者均有症状性内侧和髌股关节间室骨关节炎，前交叉韧带完整，外侧间室在普通放射学和磁共振成像上完好无损。在术前和术后 1、2、5 和 10 年使用牛津膝关节评分（OKS）、欧洲五维健康量表自我报告问卷（EQ-5D）和最大主动活动范围（ROM）进行临床评估。
30 例（37 膝）平均随访时间为 11.4 年（SD 1.1；范围 10.5-14.0）。8 例（10 膝）死亡，3 例在最终随访时无法联系。没有进行主要部件修订。术前 OKS 25.4（SD 5.2；范围 15-40），膝关节屈曲 116.4°（SD 10.3°；范围 100°-140°）和 EQ-5D 70.5（SD 19.9；范围 25-95）。10 年 OKS 43.5（SD 4.1；范围 32-48），膝关节屈曲 127.3°（SD 11.1°；范围 105°-144°）和 EQ-5D 77.4（SD 9.3；范围 60-100）。OKS（p<0.0001）、EQ-5D（p=0.024）和主动膝关节屈曲 ROM（p<0.0001）在术后 1 年均显著改善，此后至 10 年的任何随访时间内，这些评分均无进一步显著变化。胫骨 32%（7/22）和股骨 45%（10/22）的组件在 2-5 年和 10 年随访时显示出进行性透亮线。
这是文献中描述的接受 BCKA（使用 Journey-Deuce 假体）并具有最长随访时间的最大患者队列。10 年后，患者的临床结果显著改善，与其他手术关节置换选择相当。没有进行主要部件修订。胫骨 32%和股骨 45%的组件出现进行性透亮线，但无相应的松动临床迹象。
III 级。
