Abstract：
The menisci increase the stability of the tibio-femoral joint, distribute axial load, absorb shock, and provide nutrition and lubrification to the knee articular cartilage. Therefore, is it clear the importance of the meniscus on the overall knee function and the need to preserve it during arthroscopic surgery. However, according to many registry databases, meniscectomy is still the most performed meniscus surgery. In a percentage of patients, knee pain and swelling, as well as bone edema on the tibial plateau, could follow meniscus resection; this constellation of symptoms is known as \"post-meniscectomy syndrome\". If this syndrome is not promptly managed, a rapid worsening of the symptoms and develop of knee osteoarthritis could be expected. While dealing with such condition, the clinician must perform first an accurate clinical examination and a full radiological evaluation. If the patient is candidate for surgery, the replacement of the resected tissue should be performed: a meniscus allograft should be implanted in case of previous total meniscectomy or a meniscus scaffold if the patients has an history of a previous partial resection. The present article represents a comprehensive review of the literature and aims to discuss basic science, preoperative planning and evaluation, indication, surgical technique, and outcomes of the lateral collagen meniscus implant (CMI), a biologic scaffold aimed at replacing partial meniscal defects.
摘要：
半月板增加了胫股关节的稳定性，分配轴向载荷，吸收震动,并为膝关节软骨提供营养和润滑。因此,是否清楚半月板对整体膝关节功能的重要性以及在关节镜手术期间保留半月板的必要性。然而,根据许多注册表数据库，半月板切除术仍然是最常见的半月板手术。在一定比例的患者中，膝盖疼痛和肿胀，以及胫骨平台上的骨水肿，可以在半月板切除术后；这种症状被称为“半月板切除术后综合征”。如果这种综合症没有得到及时治疗，可以预期症状的迅速恶化和膝骨关节炎的发展。在处理这种情况时，临床医生必须首先进行准确的临床检查和全面的放射学评估.如果病人是手术的候选人，切除的组织应进行置换：如果先前进行过半月板全切除术，则应植入半月板同种异体移植物，或者如果患者有先前部分切除的病史，则应植入半月板支架。本文是对文献的全面回顾，旨在讨论基础科学，术前计划和评估，指示,外科技术,和外侧胶原半月板植入物（CMI）的结果，旨在替代半月板部分缺损的生物支架。
