Lateral meniscus tears are a common entity seen in sports medicine. Although lateral-side knee pain is often the result of a meniscus injury, several extra-articular pathologies share signs and symptoms with a meniscus tear. It is critical for the clinician to be able to identify and understand extra-articular pathologies that can present similar to a lateral meniscus tear.
Data were collected through a thorough review of the literature conducted through a MEDLINE search for all relevant articles between 1980 and February 2010.
Clinical review.
Common extra-articular pathologies that can mimic lateral meniscal tears include iliotibial band syndrome, proximal tibiofibular joint instability, snapping biceps femoris or popliteus tendons, and peroneal nerve compression syndrome or neuritis. The patient history, physical examination features, and radiographic findings can be used to separate these entities from the more common intra-articular knee pathologies.
In treating patients who present with lateral-sided knee pain, clinicians should be able to recognize and treat extra-articular pathologies that can present in a similar fashion as lateral meniscus tears.
外侧半月板撕裂是运动医学中常见的病症。尽管外侧膝关节疼痛通常是半月板损伤的结果，但有几种关节外病变与半月板撕裂具有相同的体征和症状。临床医生能够识别和理解可能表现为外侧半月板撕裂的关节外病变非常重要。
通过对从 1980 年到 2010 年 2 月期间所有相关文章进行的 MEDLINE 搜索，全面回顾文献收集数据。
临床综述。
常见的可模拟外侧半月板撕裂的关节外病变包括髂胫束综合征、胫骨近端腓骨联合不稳定、股二头肌或腓肠肌腱弹响、腓总神经压迫综合征或神经炎。患者病史、体格检查特征和影像学检查结果可用于将这些病变与更常见的关节内膝关节病变区分开来。
在治疗出现外侧膝关节疼痛的患者时，临床医生应该能够识别和治疗以类似方式表现为外侧半月板撕裂的关节外病变。
