Cohort study 

研究目的:

本研究旨在评价个性化全膝关节置换系统在终末期膝骨关节炎患者中的临床优势。通过比较其与传统TKA在术后恢复、功能改善、并发症发生率及假体匹配方面的差异,为TKA手术方式的选择提供依据。  

Objectives of Study:

This study aims to evaluate the clinical advantages of a personalized total knee arthroplasty (TKA) system in patients with end-stage knee osteoarthritis, compared with conventional TKA. The goal is to assess postoperative recovery, functional improvement, complication rates, and prosthesis matching.
