随着人口老龄化进程的发展,膝关节的退行性病变逐渐增多,关节内软骨退变、滑膜增生,骨赘形成,半月板继发改变,导致关节间隙变窄,功能受损甚至丧失,并伴有关节的肿胀、疼痛,最终导致膝关节骨性关节炎和关节病变;且膝关节骨折是一种多发性损伤,常并发有前、后交叉韧带、侧副韧带等损伤及关节腔积血等。经内固定术后关节功能常受影响,严重者可出现膝关节强直。传统的治疗方法为关节镜下磨削后打孔的“微骨折”技术。而关节镜下关节清理结合缺损区微骨折技术主要是利用骨髓间充质干细胞的体内自我诱导分化为成软骨细胞。从而形成软骨组织。术后膝关节功能可得到显著改善。2012年5月~2014年12月,本科室采用关节镜下关节清理结合缺损区磨削后打孔的“微骨折”技术治疗了膝骨性关节炎伴软骨缺损患者21例,术后制订了有效的康复训练计划,使患者关节疼痛及活动范围恢复良好。
With the development of aging population, degenerative knee joint gradually increased, cartilage degeneration, synovial hyperplasia, osteophyte formation, secondary meniscus changes, resulting in joint space narrowing, impaired or even loss of function, And accompanied by joint swelling, pain, eventually leading to knee osteoarthritis and joint disease; and knee fracture is a multiple injury, often complicated by anterior cruciate ligament, collateral ligament injury and joint cavity product Blood and so on. Joint function after internal fixation often affected, in severe cases there may be knee stiffness. The traditional method of treatment is the “microfracture” technique of drilling after arthroscopy. Arthroscopic joint debridement combined with defect microfracture technology is the use of bone marrow mesenchymal stem cells in vivo self-induced differentiation into chondrocytes. Thus forming cartilage tissue. Postoperative knee function can be significantly improved. From May 2012 to December 2014, 21 cases of knee osteoarthritis with cartilage defects were treated with arthroscopic joint debridement combined with perforating “micro-fracture” technique in the defect area. After operation Developed an effective rehabilitation training program to restore the patient’s joint pain and range of activities.
