Disorders related to the knee extensor mechanism are common and rarely require imaging. Non specific anterior knee pain, fracture, dislocation, overuse tendinopathy and chronic patellofemoral instability are the commonest conditions encountered. Imaging is used in acute trauma, and for the assessment of cases of anterior knee pain resistant to conservative measures. The role of the radiograph is now largely restricted to cases of suspected fracture. Ultrasound is the optimum technique for suspected tendon and bursal pathology and MRI is widely used for the assessment of dysplasia and instability of the patellofemoral joint, including acute dislocation.
与膝关节伸肌机制相关的疾病很常见，很少需要影像学检查。非特异性膝前疼痛、骨折、脱位、过度使用性肌腱病和慢性髌股关节不稳定是最常见的情况。影像学检查用于急性创伤以及评估对保守治疗无效的膝前疼痛病例。X线片目前的作用主要局限于疑似骨折的病例。超声是怀疑肌腱和滑囊病变的最佳检查技术，而MRI广泛用于评估髌股关节的发育异常和不稳定，包括急性脱位。
