Marrow stimulation techniques, including microfracture, are among the most commonly performed cartilage restoration procedures for symptomatic chondral defects of the knee. For the vast majority of patients, marrow stimulation results in reduced pain and improved function, providing overall satisfactory outcomes. In some cases, however, marrow stimulation fails, resulting in symptom recurrence and often, the need for repeat surgery. This review will describe the indications and outcomes of microfracture as a primary surgical treatment for focal chondral defects of the knee, identify patient and procedure-specific factors associated with poor clinical outcomes, and will discuss treatment options and their respective outcomes for patients with a failed prior microfracture surgery.
包括微骨折术在内的骨髓刺激技术，是针对膝关节有症状的软骨缺损最常用的软骨修复手术之一。对于绝大多数患者而言，骨髓刺激可减轻疼痛并改善功能，总体效果令人满意。然而，在某些情况下，骨髓刺激会失败，导致症状复发，而且常常需要再次手术。本综述将描述微骨折术作为膝关节局灶性软骨缺损主要手术治疗方法的适应症及疗效，确定与临床疗效不佳相关的患者及手术特定因素，并将讨论先前微骨折手术失败患者的治疗选择及其各自的疗效。
