Isolated injuries to the posterolateral corner of the knee are a rare and commonly missed injury associated with athletic trauma, motor vehicle accidents, and falls. Delayed or missed diagnoses can negatively impact patient prognosis, contributing to residual instability, chronic pain, and failure of surgical repair to other ligaments.
A 44-year-old male CrossFit athlete presented with a history of two non-contact hyperextension injuries to his left knee while walking on ice. The only positive finding was the Dial Test at 30 degrees of knee flexion, indicative of an isolated posterolateral corner injury. After a delay in diagnosis, the patient underwent a reconstruction of the posterolateral corner and subsequent rehabilitation. Early recognition of this injury is important as this can affect the prognosis and activities of daily living of the patient.
This case will discuss the clinical presentation, diagnostic procedures, and management of an isolated posterolateral corner injury and highlight the importance of early recognition and referrals from primary contact healthcare practitioners.
膝关节后外侧角孤立损伤较为罕见，常因运动创伤、机动车事故和跌倒而漏诊。诊断延迟或漏诊会对患者预后产生负面影响，导致残留不稳定、慢性疼痛以及其他韧带手术修复失败。
一名44岁的男性CrossFit运动员，有两次在冰上行走时左膝非接触性过度伸展损伤史。唯一的阳性发现是膝关节屈曲30度时的Dial试验阳性，提示孤立的后外侧角损伤。诊断延迟后，患者接受了后外侧角重建及后续康复治疗。早期识别这种损伤很重要，因为这会影响患者的预后和日常生活活动。
本病例将讨论孤立性后外侧角损伤的临床表现、诊断程序和治疗，并强调早期识别以及初级接触医疗从业者转诊的重要性。
