Objective To explore diagnostic method and surgical outcome of lateral patellofemoral crush syndrome caused by military training. Methods Fifteen patients with lateral patellofemoral crush syndrome caused by military training from May 2006 to May 2008 were enrolled in this study, including 12 men (14 knees) and 3 women (3 knees), aged from 22 to 43 years old with an average of 27.3 years. Randomly selected 18 healthy volunteers with similar age and gender but no knee pain symptom were selected to serve as a control group. Anteroposterior and lateral X-ray photographs of knee joint and axial photographs of the patella were taken in both groups for observing the bone architecture of the knee joint and measuring the femoral trochlear angle, patellofemoral congruence angle and patellofemoral index, and the data were compared. The 17 knee joints in patient group were treated with lateral patellar retinaculum release. Then the preoperative and postoperative pain severity was evaluated with visual analogue scale (VAS). Results Patellofemoral congruence angle was 7.67° ± 5.8° and patellofemoral index was 2.49 ± 1.40 in patient group, while they were -2.2° ± -2.71° and 1.2S ± 0.15 in control group. The difference between two groups showed statistical significance (P<0.05). The change in bone architecture was obvious in patient group. The preoperative pain score was 7.06 ± 0.85, and postoperative pain score was 3.87 ± 0.24 after 6 months and 3.01+0.17 after 1 year in patient group. The difference between preoperative pain score and postoperative pain score showed statistical significance (P<0.OS). Conclusions Diagnosis of patellofemoral crush syndrome caused by military training requires a combination of case history, typical symptoms, objective sign and X-ray examination. Among these, X-ray examination is the fundamental auxiliary diagnostic tool for lateral patellofemoral crush syndrome, and the patellofemoral index is convenient for diagnosis.%目的 探讨军事训练所致外侧髌股挤压综合征的诊断方法及手术治疗效果.方法 收集2006年5月-2008年5月收治的军事训练所致外侧髌股挤压综合征患者15例(病例组),男12例(14膝),女3例(3膝),年龄22～43岁,平均27.3岁.以随机抽取的18名年龄性别匹配、无膝痛症状的健康志愿者作为对照组.两组患者均接受膝关节正侧位及髌骨轴位X线片检查,观察膝关节骨质结构情况,测量滑车角、适合角及髌股指数并进行组间比较.病例组患者均实施髌外侧支持带松解术,并对术前和术后疼痛程度(VAS法)进行评估.结果 病例组适合角(7.67°±5.81°)及髌股指数(2.49±1.40)均明显大于对照组(适合角-2.2°±-2.71°,髌股指数1.25±0.15),差异有统计学意义(P＜0.01,P＜0.05),而滑车角(132.44°±10.21°)与对照组(136.80°±4.87°)比较差异无统计学意义(P＞0.05),且病例组膝关节骨质结构改变明显.病例组术前疼痛程度评分为7.06±0.85,明显高于术后6个月(3.87±0.24)及术后1年(3.01±0.17),差异有统计学意义(P＜0.05),而术后6个月与术后1年的疼痛程度评分差异无统计学意义(P＞0.05).结论 军事训练所致外侧髌股挤压综合征的诊断需结合病史、典型临床症状、体征及X线检查并注意鉴别诊断.膝关节X线片是诊断外侧髌股挤压综合征最基本的辅助检查手段,其中髌股指数应用方便.
