Meniscal root tears function as a complete meniscectomy, with loss of hoop stress due to the detachment of the meniscus. Root tears have been increasingly recognized recently with improvements in diagnostic imaging and the understanding of meniscal biomechanics. Patients have a high rate of progression of osteoarthritis and subsequent knee replacement after a meniscal root tear. Recent advances in repair techniques, arthroscopic instrumentation, and biological augmentation strategies continue to offer surgeons ways to manage historically "irreparable" meniscal tears. Root repair clinical outcomes are generally favorable, although patients may still experience progressive degenerative changes.
半月板根部撕裂的功能相当于完全切除半月板，由于半月板的分离，会丧失环形张应力。随着诊断影像学的进步和对半月板生物力学的理解，最近人们越来越认识到根部撕裂。半月板根部撕裂后，患者的骨关节炎进展率和随后的膝关节置换率都很高。修复技术、关节镜器械和生物增强策略的最新进展继续为外科医生提供了治疗历史上“不可修复”半月板撕裂的方法。根部修复的临床结果通常是良好的，尽管患者仍可能经历进行性退行性变化。
