Abstract

Total knee arthroplasty (TKA) in valgus knee deformities presents unique challenges, including alignment, soft tissue balance, and implant positioning. The lateral approach offers advantages over the traditional medial approach by improving direct access, patellar tracking, and soft tissue preservation. Robotic-assisted TKA enhances precision, ligament balancing, and patient-specific alignment strategies, such as functional knee positioning (FKP). This study describes a surgical technique integrating the lateral approach with robotic-assisted TKA using FKP principles. The technique is based on an image-based robotic system, ensuring accurate preoperative planning, intraoperative adjustments, and optimized prosthetic placement. Key intraoperative steps, including bone resection strategies, soft tissue balancing, and trial component evaluations, are detailed. The lateral robotic approach with FKP was found to be effective and reproducible, allowing for precise implant alignment and optimized soft tissue balance in valgus knees. This method minimizes the need for extensive lateral releases, preserves vascularity, and ensures postoperative stability. The combination of the lateral approach, robotic-assisted TKA, and FKP represents a promising strategy for valgus knee deformities. Further long-term studies are needed to validate the durability and functional benefits of this technique.

外翻膝机器人全膝关节置换术的外侧入路:一步一步的技术。
全膝关节置换术(TKA)外翻膝关节畸形提出了独特的挑战,包括对齐,软组织平衡和植入物定位。外侧入路优于传统内侧入路,可改善直接入路、髌骨追踪和软组织保存。机器人辅助TKA提高精确度,韧带平衡,和患者特定的对齐策略,如功能性膝关节定位(FKP)。本研究描述了一种利用FKP原理将外侧入路与机器人辅助TKA相结合的外科技术。该技术基于基于图像的机器人系统,确保准确的术前计划、术中调整和优化假体放置。关键的术中步骤,包括骨切除策略,软组织平衡和试验组件评估,详细介绍。采用FKP的外侧机器人入路是有效且可重复的,可以在外翻膝关节中实现精确的植入物对齐和优化的软组织平衡。该方法最大限度地减少了广泛侧位松解的需要,保持了血管通畅,并确保了术后的稳定性。外侧入路、机器人辅助TKA和FKP的结合是治疗外翻膝关节畸形的一种很有前途的策略。需要进一步的长期研究来验证该技术的耐久性和功能优势。
