研究目的:

主要目的:在真实世界场景中,通过 PSM 及 SIPTW 控制基线混杂因素后,比较 MMSA 与 MPA 在初次 TKA 中的有效性及安全性,明确 MMSA 在减少围手术期失血、缓解术后早期疼痛、改善术后早期膝关节功能恢复方面的优势 次要目的:1. 评估两种入路对假体植入准确性、2 年长期膝关节功能及假体生存率的影响;2. 比较术后并发症发生率及手术相关指标;3. 分析 MMSA 在不同亚组中的临床效果;4. 验证 PSM 及 SIPTW 控制混杂因素的有效性  

Objectives of Study:

Primary objective: To compare the efficacy and safety of MMSA versus MPA in primary TKA after controlling baseline confounders using PSM and SIPTW in a real-world setting, and to confirm the advantages of MMSA in reducing perioperative blood loss, relieving early postoperative pain, and improving early postoperative knee function recovery Secondary objectives: 1. To evaluate the effects of the two approaches on prosthesis implantation accuracy, 2-year long-term knee function and prosthesis survival rate; 2. To compare the incidence of postoperative complications and surgery-related indicators; 3. To analyze the clinical effects of MMSA in different subgroups; 4. To verify the effectiveness of PSM and SIPTW in controlling confounders
