Abstract：
The discoid meniscus is a common congenital meniscal malformation that is prevalent mainly in Asians and often occurs in the lateral discoid meniscus. Patients with asymptomatic discoid meniscus are usually treated by conservative methods such as observation and injury avoidance, while patients with symptoms and tears need to be treated surgically. Arthroscopic saucerization combined with partial meniscectomy and meniscus repair is the most common surgical approach., and early to mid-term reports are good. The prognostic factors are the patient\'s age at surgery、follow-up time and type of surgery. Some patients experience complications such as prolonged postoperative knee pain, early osteoarthritis, retears and Osteochondritis dissecans. The incidence of prolonged postoperative knee pain was higher and the incidence of Osteochondritis dissecans was the lowest. Retears of the lateral meniscus is the main reason for reoperation.
摘要：
盘状半月板是一种常见的先天性半月板畸形，主要在亚洲人中普遍存在，通常发生在盘状半月板外侧。无症状盘状半月板患者通常采用观察、避免损伤等保守方法治疗,而有症状和流泪的患者需要手术治疗。关节镜下开式联合半月板部分切除术和半月板修复是最常见的手术方法。,早期到中期报告都很好。影响预后的因素是患者的手术年龄、随访时间和手术类型。一些患者会出现并发症，如术后膝关节疼痛延长，早期骨关节炎,再撕裂和剥离骨软骨炎。术后膝关节长期疼痛的发生率较高，剥脱性骨软骨炎的发生率最低。外侧半月板的保留是再次手术的主要原因。
