研究目的:

1.通过对关节镜下单纯微骨折术治疗、微骨折+自体髂骨红骨髓增强和微骨折+自体富血小板血浆注射术三种治疗方案治疗距骨骨软骨损伤,对患者术后距骨骨软骨修复的影像学随访分析,对比三种治疗方案的疗效。 2.通过对距骨骨软骨损伤患者术中取样组织(滑膜、关节液、局部钻孔后渗出血液等)检测,对免疫微环境及表观遗传性状分析,探索影响距骨骨软骨损伤修复失败的可能机制。  

Objectives of Study:

1.Through the treatment of talar osteochondral lesions with three different bone marrow stimulation (BMS, or microfracture) procedures: standard arthroscopic microfracture, microfracture augmented with autologous iliac bone marrow, and microfracture augmented with autologous platelet-rich plasma, an analysis was conducted on the regeneration process of the repair tissue in the talar osteochondral tissue. The aim was to identify the enhanced bone marrow stimulation that resulted in better healing and restoration of the talar osteochondral integrity. 2. By examining the immune biomarkers and epigenetic characteristics of the obtained local tissue during surgery, and analyzing the characteristics of the repaired tissue on postoperative MRIs, the study seeks to explore the potential mechanisms that may lead to the failure of talar osteochondral lesion repair.

药物成份或治疗方案详述:

1.评估患者术后距骨骨软骨修复情况,研究三组手术治疗方案对距骨骨软骨损伤修复的治疗效果差异,同时术中收集患者关节液及血液标本。 (1)在我院接受踝关节镜手术距骨骨软骨损伤修复术后随访1-2年患者,符合研究纳入标准,并签署手术同意书的同时对本项目充分知情并签署知情同意书。 (2)术中采用统一手术方式,所有患者均采用关节镜踝关节距骨骨软骨微骨折治疗术,术中清理病损剥脱软骨组织,显露软骨下骨,显露硬化区域,用微骨折锥在缺损区骨质上穿孔后,刺激血细胞、骨髓细胞、软骨源性和骨源性细胞渗透到损伤区,A组患者抽取适量踝关节关节液用于检测,B组患者额外从髂骨抽取红骨髓后注射进关节腔,并取适量红骨髓检测,C组患者将术前或术中准备的自体富血小板血浆注射入关节腔,同样取适量富血小板血浆液体用于检测。 (3)手术后,下肢被放置在抬高的位置,同时应用冷疗。每天进行4-6小时的连续被动运动(CPM)。在2-4周内使用拐杖,以进行非负重运动。2周后,鼓励使用气垫靴进行20公斤部分负重行走。接下来的阶段,推荐进行包括加强下肢肌肉和本体感知神经肌肉促进(PNF)的康复练习。患者在术后3个月可以逐渐恢复低冲击活动,包括慢跑、游泳和骑自行车。然而,术后6个月内禁止恢复竞技运动。 (4)记录了所有患者的特征(包括年龄、性别、职业、体质指数、吸烟情况、损伤部位、损伤直径、合并的前踝外侧韧带损伤和随访时间)。患者在术后3个月、6个月、12个月和24个月进行了随访检查,然后每年一次。评估项目包括:足踝能力量表(FAAM),包括日常生活活动(ADL)和运动子量表,磁共振观察软骨修复组织(MOCART)2.0评分。并记录并评估了并发症和修复手术。 (5)MOCART 2.0评分基于7个相关变量,为软骨修复的形态学评估提供了一种标准化、可重复的半定量方法,包括软骨缺损的填充量、与相邻软骨的整合、修复组织的表面、修复组织的结构、信号强度、骨性缺损或过度生长,以及软骨下骨的变化。 2.距骨骨软骨损伤术中关节液微泌体差异分析及标志物检测,软骨组织局部免疫微环境检测及表观遗传机制研究 (1)对三组患者术中收集关节液及血液标本进行检测,A组患者检测标本为踝关节关节液,B组患者检测标本为踝关节液及患者自身红骨髓,C组患者检测标本为踝关节液及患者自体富血小板血浆。 (2)对三种标本微泌体质谱分析和测序,结果进行生信分析(差异的miRNA及IncRNA),检测免疫相关因子:IGF, TGF-β, TNF-α, IL-1β, IL-4, IL-6, IL-10等,探索相关标志物。 (3)根据患者术后随访软骨修复情况,对比患者标本检测结果,验证不同微泌体对软骨细胞生长的刺激作用。 (4)免疫相关信号通路结果验证(体外细胞试验)  

Description for medicine or protocol of treatment in detail:

1. During surgery, local damaged cartilage, synovial fluid, autologous iliac bone marrow, and autologous PRP will be collected. Local bone marrow effused from the microfracture site also will be obtained in each case. The regenerated process of the repaired tissue in the talar osteochondral lesions will be assessed during follow-ups. (1)Patients who will undergo the arthroscopic BMS procedure in our hospital are followed up for 24 months and beyond. Those who are fully informed about this project and meet the inclusion criteria will be asked to sign the surgical consent form. (2)During surgery, the unified surgical method will be applied. All patients undergo standard arthroscopic microfracture procedures. The damaged and detached cartilage will be debrided and collected, to expose the subchondral bone. After drilling holes at the lesion site with a small-sized microfracture awl, bone marrow cells, chondrogenic and osteogenic cells will be stimulated to infiltrate the lesion site. In Group A, an appropriate amount of local bone marrow will be extracted using a syringe without irrigation. In Group B, autologous iliac bone marrow will be injected into the lesion site, while additional iliac bone marrow will be collected for testing. In Group C, autologous platelet-rich plasma prepared preoperatively or intraoperatively will be injected into the lesion site, and an appropriate amount of platelet-rich plasma is also collected for testing. (3)Following surgery, the lower limb was placed in an elevated position while the cryotherapy was applied. Continuous passive motion (CPM) was initiated for 4-6 hours a day. Crutches were utilized for 2-4 weeks to allow non-weight bearing exercise. After 2 weeks, 20 kg partial-weight bearing, walking with the use of air boots was encouraged. Rehabilitation exercises including strengthening of the lower extreme muscles and proprioceptive neuromuscular facilitation (PNF) were recommended for the following period. The patients could gradually resume low-impact activities after 3 months, including jogging, swimming, and cycling. However, returning to competitive sports is prohibited before 6 months postoperative. (4)All Patients’ characteristics (including age, gender, occupation, BMI, smoke, lesion location, lesion diameter, concomitant anterior talofibular ligament injures, and follow-up time) were recorded. Patients had a postoperative examination at 3, 6, 12, and 24 months then yearly. The evaluation items include: The Foot and Ankle Ability Measure scales (FAAM), including activities of daily living (ADL) and sports subscales, Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) 2.0 scores. The complications and revision procedures were also recorded and assessed. (5)The MOCART 2.0 scores are based on 7 pertinent variables and facilitated a standardized, reproducible, semiquantitative approach for the morphological assessment of cartilage repair, including volume fill of cartilage defect, integration into adjacent cartilage, surface of the repair tissue, structure of the repair tissue, signal intensity, bony defect or overgrowth, and subchondral changes. 2. Analysis of the immune microenvironment and differences of bio-markers in synovial fluid, bone marrow samples and local damaged cartilage tissue. (1) During surgery, synovial fluid, local damaged cartilage tissue, local and iliac bone marrow, and autologous platelet-rich plasma samples from the three groups will be collected for testing. (2) The different types of specimens will undergo microvesicles mass spectrometry analysis and sequencing. The results will be analyzed bioinformatically for differential miRNA and lncRNA. Immune-related factors such as IGF, TGF-β, TNF-α, IL-1β, IL-4, IL-6, IL-10, etc., will be tested to explore relevant biomarkers. (3) Based on the postoperative follow-up of the patients' cartilage repair process, comparing the results of the patients' specimens, the stimulating effect of different microvesicles on cartilage regeneration is validated. (4) Verification of immune-related signaling pathway results (in vitro cell experiments).
