Objective: To investigate the mid-to-long-term efficacy of patients with chronic ankle instability combined with posterior impingement syndrome after 3-9 years of follow-up, and to analyze the influencing factors.
Methods: From February 2010 to December 2015, 46 patients underwent concurrent lateral ankle ligament repair with posterior ankle arthroscopic surgery at the Institute of Sports Medicine, Peking University Third Hospital. The patient was first placed in a prone position and underwent arthroscopic debridement for the posterior impingement. After finishing the posterior arthroscopy, the surgeon and assistants first translated the patient to the affected side, then turned to the healthy side, and changed the position to the supine position. During the turning over, another assistant held the arthroscope and the instrument to ensure that it was sterile and could be used without replacement. The anterior ankle arthroscopy was operated if necessary and the lateral ankle ligament repair was anatomic repaired with anchors. The 42 patients were followed up, including 26 males and 16 females. The average age was (28.9±10.0) years. The patient's clinical symptoms, joint stability, mobility and motor function were compared by questionnaire and physical examination. The preoperative and postoperative visual analogue scale (VAS) scores, American Orthopaedic Foot and Ankle Society (AOFAS) scores, Tegner scores were compared, and the clinical scores and the patient age, gender, height and weight were compared. The correlations between body mass index (BMI), preoperative duration, surgery duration, and cartilage injury were analyzed.
Results: The mean follow-up time was (71.8±22.8) months. The postoperative VAS scores (1.0 vs. 5.0, P<0.001), AOFAS scores (92 vs. 80, P<0.001), and Tegner scores (6.5 vs. 2, P<0.001) were significantly superior to the preoperative levels. The excellent and good rate was 97.6%. The postoperative VAS score (t=2.719, P=0.10), AOFAS score (t=-2.853, P=0.10), Tegner score (t=-3.443, P=0.001) and time to return exercise (t=2.814, P=0.008) were negatively correlated with the patient age, and the postoperative VAS score was negatively correlated with cartilage injury (Z=-2.195, P=0.028).
Conclusion: The mid-to-long-term clinical outcomes of the chronic ankle ligament instability combined with the posterior impingement were good. The age of the patients was negatively correlated with the clinical outcome. The combined cartilage injury could aggravate the postoperative pain.
目的: 对慢性踝关节不稳合并后踝撞击综合征患者术后进行3~9年的随访,探讨其中长期疗效,并对其影响因素进行分析。
方法: 2010年2月—2015年12月于北京大学第三医院运动医学研究所接受外踝韧带修复和后踝关节镜清理同期手术的患者共47例,随访42例,其中男性26例、女性16例,平均年龄(28.9±10.0)岁。通过问卷及查体记录患者的临床症状、关节稳定性、活动度及运动机能等,对比术前和术后疼痛视觉模拟评分(visual analogue scale,VAS)、美国足踝外科协会(American Orthopaedic Foot and Ankle Society,AOFAS)后足评分、运动机能Tegner评分,并分析临床评分与患者年龄、性别、身高、体重指数、受伤时间、手术用时、软骨损伤等因素的相关性。
结果: 平均随访时间为(71.8±22.8)个月。患者术后VAS评分、AOFAS评分及Tegner评分均优于术前水平(1.0 vs. 5.0, 92 vs. 80, 6.5 vs. 2.0, P均<0.001),疗效优良率为97.6%,术后VAS评分(t=2.719,P=0.10)、AOFAS评分(t=-2.853,P=0.10)、Tegner评分(t=-3.443,P=0.001)和恢复运动时间(t=2.814,P=0.008)均与患者年龄呈负相关,术后VAS评分与软骨损伤呈负相关(Z=-2.195,P=0.028)。
结论: 慢性踝关节不稳合并后踝撞击同期手术后的中长期临床效果良好,患者年龄与临床疗效呈负相关,合并软骨损伤可加重患者术后疼痛。
