Abstract

Background: Unicompartmental knee arthroplasty (UKA) is a viable treatment option for patients with isolated knee osteoarthritis. This study evaluated the clinical outcomes of the JUK II (Smith & Nephew, Memphis, TN, US) hypoallergenic, fixed-bearing UKA implant in a medium cohort of patients undergoing both medial and lateral procedures with a short-term follow-up.

Methods: A retrospective review was conducted on 257 consecutive patients who underwent primary UKA using the JUK II implant between December 2020 and December 2022. Clinical outcomes were assessed using the Knee Society Score (KSS), Knee Society Function Score (KSFS), Oxford Knee Score (OKS), UCLA Activity Score, Forgotten Joint Score (FJS-12) and the satisfaction. Survivorship analysis was performed, and complications were recorded.

Results: At a 2-year follow-up, the implant survival rate was 99.61%. Statistical significant improvements were observed in all clinical scores, with high patient satisfaction. The mean UCLA Activity Score increased from 4.53 preoperatively to 7.3 at 24 months.

Conclusions: This study demonstrates promising short-term clinical outcomes for the hypoallergenic fixed-bearing medial and lateral UKA implant, with high patient satisfaction and a low complication rate. Further studies with longer follow-up periods are warranted to confirm these findings.

摘要
背景：单髁膝关节置换术（Unicompartmental Knee Arthroplasty，UKA）是治疗孤立性膝关节骨关节炎患者的可行方案。本研究针对接受内侧与外侧单髁置换术的中等规模患者队列开展短期随访，评估JUK II（Smith & Nephew，美国田纳西州孟菲斯市）低致敏性固定承重型UKA假体的临床疗效。
方法：本研究对2020年12月至2022年12月期间，257例连续入组且接受JUK II假体初次单髁膝关节置换术的患者进行回顾性分析。采用膝关节学会评分（Knee Society Score，KSS）、膝关节学会功能评分（Knee Society Function Score，KSFS）、牛津膝关节评分（Oxford Knee Score，OKS）、加州大学洛杉矶分校活动评分（UCLA Activity Score）、失忆关节评分（Forgotten Joint Score-12，FJS-12）及患者满意度对临床结局进行评估。同时开展假体生存率分析并记录并发症发生情况。
结果：术后2年随访时，该假体生存率达99.61%。所有临床评分均较术前获得具有统计学意义的显著改善，患者满意度较高。加州大学洛杉矶分校活动评分均值从术前的4.53提升至术后24个月时的7.3。
结论：本研究证实，低致敏性固定承重型内侧及外侧单髁膝关节置换假体的短期临床疗效良好，患者满意度高且并发症发生率低。后续需开展更长随访周期的研究以验证本研究结果。
