Outpatient rehabilitation clinic.
A 37-year-old physically active male.
The patient presented with anterior left knee pain, exacerbated when climbing stairs, sitting, and running. Exam showed lateral tracking patellae and palpable crepitus. One hundred fifty units of botulinum toxin A was injected into his left vastus lateralis. He underwent a 12-week home exercise program targeting the vastus medialis (VM). ASSESSMENT/RESULTS: Visual analog scale decreased from 70 to 0 on a 150-mm scale, from initial until 8 weeks postinjection. Functional Index Questionnaire increased from 5 to 16 over the same period. Knee torque and surface electromyography findings showed increased activity of the VM during knee extension.
Botulinum injection into the vastus lateralis in conjunction with VM strengthening may provide more effective treatment of patellofemoral pain syndrome. Further study is needed to explore this novel treatment of patellofemoral pain syndrome.
门诊康复诊所。
一名37岁身体活跃的男性。
患者出现左膝前部疼痛，在爬楼梯、坐着和跑步时加重。检查发现髌骨外侧移位和可触及的摩擦音。向其左侧股外侧肌注射了150单位A型肉毒杆菌毒素。他接受了为期12周的针对股内侧肌（VM）的家庭锻炼计划。
评估/结果：在150毫米的视觉模拟量表上，从注射初始至注射后8周，评分从70降至0。同期功能指数问卷从5增至16。膝关节扭矩和表面肌电图结果显示，在膝关节伸展过程中股内侧肌的活动增加。
向股外侧肌注射肉毒杆菌毒素并结合股内侧肌强化训练可能为髌股关节疼痛综合征提供更有效的治疗方法。需要进一步研究来探索这种治疗髌股关节疼痛综合征的新方法。
