Ruptures of the extensor mechanism of the knee are serious injuries requiring prompt diagnosis and treatment. They can be divided into soft tissue and bony causes. Soft tissue tendon injuries can be either partial or complete. Rupture of the quadriceps tendon is an uncommon injury and is more frequent in patients over the age of 40 years. Patella tendon ruptures are even rarer and are more frequent in patients under the age of 40 years. Causes can be direct or indirect. Complete ruptures of the quadriceps tendon or patella tendon benefit from early surgical management, while partial ruptures may be managed non-operatively. This article gives an overview of the presentation, assessment and management of soft tissue extensor mechanism tendon ruptures for core surgical, acute care common stem and emergency medicine trainees.
膝关节伸肌机制的破裂是严重的损伤，需要及时诊断和治疗。它们可以分为软组织和骨原因。软组织肌腱损伤可以是部分的或完全的。股四头肌肌腱断裂是一种不常见的损伤，在 40 岁以上的患者中更为常见。髌腱断裂更为罕见，在 40 岁以下的患者中更为常见。原因可以是直接的或间接的。股四头肌肌腱或髌腱完全断裂需要早期手术治疗，而部分断裂可能可以非手术治疗。本文为核心外科、急性护理普通科和急诊医学培训生提供了软组织伸肌机制肌腱断裂的表现、评估和管理概述。
