A 3 year study of 117 quadriceps contusions in West Point cadets was undertaken to document the effectiveness of a three-phased therapy program to return these young athletes to full activity with a normal knee range of motion and without recurrence of injury. The treatment protocol of this study was modeled after the 1973 West Point study of Jackson and Feagin with two major changes: 1) resting the injured leg in flexion (versus extension) and 2) emphasizing early flexion exercises (versus extension). Classification of contusions was based on knee range of motion at 12 to 24 hours after the injury (mild, greater than 90 degrees; moderate, 45 degrees to 90 degrees; severe, less than 45 degrees). The average disability time was 13 days for mild, 19 days for moderate, and 21 days for severe contusions. Myositis ossificans developed in 9% of cadets and was associated with five risk factors (knee motion less than 120 degrees, injury occurring during football, previous quadriceps injury, delay in treatment greater than 3 days, and ipsilateral knee effusion.
对西点军校学员的117例股四头肌挫伤进行了为期3年的研究，以记录三阶段治疗方案的有效性，该方案旨在让这些年轻运动员恢复到完全活动状态，膝关节活动范围正常且无损伤复发。本研究的治疗方案是以1973年杰克逊和费金在西点军校的研究为蓝本，但有两个主要变化：1）将受伤的腿置于屈曲位（而非伸展位）休息，2）强调早期屈曲练习（而非伸展练习）。挫伤的分类基于受伤后12至24小时的膝关节活动范围（轻度，大于90度；中度，45度至90度；重度，小于45度）。轻度挫伤的平均残疾时间为13天，中度为19天，重度为21天。9%的学员发生了骨化性肌炎，其与五个风险因素相关（膝关节活动小于120度、在足球运动中受伤、既往股四头肌损伤、治疗延迟超过3天以及同侧膝关节积液）。
