Abstract

Aim: This study aimed to evaluate the short- and long-term outcomes and complications of total knee arthroplasty (TKA) using posterior-stabilized (PS) and cruciate-retaining (CR) prosthesis in patients with osteoarthritis (OA) and valgus knee deformity.

Methods: A retrospective analysis was conducted on 200 patients with OA and valgus knee deformity who underwent TKA between February 2021 and November 2023. The cohort was divided into the PS group (n = 108) and the CR group (n = 92). Clinical outcomes, including Range of Motion (ROM), Hospital for Special Surgery (HSS) knee score, and Visual Analog Scale (VAS) score, were assessed at 1 week, 1 month, 3 months, 6 months, and 1 year postoperatively. Pre- and postoperative valgus angles were measured, and the incidence of complications was recorded.

Results: Both groups exhibited significant postoperative improvements in ROM, HSS scores, and VAS scores compared to preoperative (p < 0.001). The CR group demonstrated superior early postoperative outcomes, with higher HSS scores, greater ROM, and lower VAS scores at 1 week, 1 month, and 3 months (p < 0.001). However, no significant differences were observed between the groups at 6 months and 1 year (p > 0.05). Radiographic analysis indicated effective correction of valgus angles in both groups postoperatively (p < 0.001), with no significant intergroup differences (p > 0.05). The complication rate was significantly lower in the CR group compared to the PS group (p < 0.05).

Conclusions: CR and PS prostheses effectively correct valgus deformity, alleviate pain, and improve knee function. However, the CR prosthesis offers advantages in reducing early postoperative pain, swelling, and complications, facilitating faster functional recovery. The selection of the appropriate prosthesis based on patient-specific characteristics is critical to optimizing TKA outcomes.

外翻畸形骨性关节炎患者全膝关节置换术后稳定与十字保留假体的临床疗效及并发症。
目的:本研究旨在评价全膝关节置换术(TKA)使用后稳定(PS)和交叉保留(CR)假体治疗骨关节炎(OA)和外翻膝畸形患者的短期和长期疗效和并发症。方法:回顾性分析2021年2月至2023年11月期间200例OA和外翻膝关节畸形患者的TKA。将该队列分为PS组(n = 108)和CR组(n = 92)。临床结果包括术后1周、1个月、3个月、6个月和1年的活动范围(ROM)、特殊外科医院(HSS)膝关节评分和视觉模拟评分(VAS)。测量手术前后外翻角,记录并发症发生情况。结果:与术前相比,两组术后ROM、HSS评分和VAS评分均有显著改善(p < 0.001)。CR组表现出较好的术后早期预后,在1周、1个月和3个月时HSS评分较高,ROM较高,VAS评分较低(p < 0.001)。然而,6个月和1年时各组间无显著差异(p < 0.05)。x线分析显示,两组患者术后外翻角度均得到有效矫正(p < 0.001),组间差异无统计学意义(p < 0.05)。CR组并发症发生率明显低于PS组(p < 0.05)。结论:CR和PS假体可有效矫正外翻畸形,减轻疼痛,改善膝关节功能。然而,CR假体在减少术后早期疼痛、肿胀和并发症,促进更快的功能恢复方面具有优势。根据患者的具体特点选择合适的假体是优化TKA结果的关键。

期刊介绍: Annali Italiani di Chirurgia is a bimonthly journal and covers all aspects of surgery:elective, emergency and experimental surgery, as well as problems involving technology, teaching, organization and forensic medicine. The articles are published in Italian or English, though English is preferred because it facilitates the international diffusion of the journal (v.Guidelines for Authors and Norme per gli Autori). The articles published are divided into three main sections:editorials, original articles, and case reports and innovations.
