研究目的:

本研究旨在通过大样本回顾性队列分析,比较全镜下MPFL重建联合内侧支持带紧缩技术与传统MPFL重建术在术后膝关节功能恢复、生物力学稳定性及并发症风险的差异,验证其在临床疗效和生物力学稳定性方面的非劣性,并探索其对术后功能恢复、并发症发生率及生物学愈合的影响。本研究的具体目的如下: 1. 验证临床效果:通过回顾性临床队列研究,比较全镜下MPFL重建联合内侧支持带紧缩技术与传统重建术在术后关节功能评分(如IKDC评分和Lysholm评分),VAS疼痛评分,实验室检查和影像学检查等临床指标上的效果差异,明确该技术是否能达到非劣性标准。 2. 评估安全性:分析术后并发症的发生率,包括术后感染、再损伤率及其他与手术相关的短期和长期不良反应,验证原位缝合技术的安全性。 3. 观察生物学愈合过程:通过影像学(MRI或CT)及组织学评估,探索全镜下MPFL重建联合内侧支持带紧缩修复的生物学愈合机制,了解其在韧带重塑及功能恢复中的生物学优势。 4. 探索适用人群:进一步明确全镜下MPFL重建联合内侧支持带紧缩技术的适用范围,规范手术操作步骤,并评估不同类型患者的术后疗效及预后差异,逐步形成动态优化的技术标准和适应症共识(“湘雅标准”),为临床医生提供明确的操作指南和适用范围,促进全镜下MPFL重建联合内侧支持带紧缩技术在复发性髌骨脱位治疗中的推广与标准化应用。  

Objectives of Study:

The aim of this study was to compare the differences in postoperative knee functional recovery, biomechanical stability, and risk of complications between the alloscopic MPFL reconstruction combined with medial support band tightening technique and conventional MPFL reconstruction through a large sample retrospective cohort analysis, to validate their non-inferiority in terms of clinical efficacy and biomechanical stability, and to explore their impact on postoperative functional recovery, complication rates, and biological healing. The specific aims of this study are as follows: 1. To validate the clinical efficacy: through a retrospective clinical cohort study, to compare the difference in the efficacy of the technique of total microscopic MPFL reconstruction combined with medial support band tightening with that of conventional reconstruction in terms of postoperative joint function scores (e.g., IKDC scores and Lysholm scores), VAS pain scores, laboratory tests, and imaging tests, and to clarify whether the technique can meet the criteria for non-inferiority. 2. Assess the safety: analyse the incidence of postoperative complications, including postoperative infections, re-injury rates and other short- and long-term adverse reactions associated with the procedure, and verify the safety of the in situ suturing technique. 3. Observe the biological healing process: Explore the biological healing mechanism of alloscopic MPFL reconstruction combined with medial support band tightening technique, understand its biological advantages in ligament remodeling and functional recovery. 4. Exploring the applicable population: Further clarify the scope of application of the arthroscopic MPFL reconstruction combined with medial patellar retinacular tightening technique, standardize surgical procedures, and evaluate the postoperative efficacy and prognostic differences among different types of patients. Gradually form dynamically optimized technical standards and consensus on indications ("Xiangya Standards"), provide clear operational guidelines and scope of application for clinicians, and promote the promotion and standardized application of the arthroscopic MPFL reconstruction combined with medial patellar retinacular tightening technique in the treatment of recurrent patellar dislocation.
