后踝关节镜术后中期临床随访研究

The mid-term follow-up of the postoperative posterior ankle arthroscopy

目的通过对后踝关节镜患者术后3-6年的随访分析，探讨后踝关节镜患者术后的中期疗效。方法选取2009年6月至2012年12月45例患者在北京大学第三医院运动医学研究所接受后踝关节镜手术，随访42例，其中男25例，女17例，平均年龄（27．1±9．6）岁。随访并对比患者术前和术后VAS、AOFAS、Tegner评分及关节活动度等。结果平均随访时间为（58．1±12．0）个月。患者术后VAS评分（0．8 vs 3．0，P〈0．001）、AOFAS评分（93．9 vs 76．5，P〈O．001）及Tegner评分（4．9 vs 3．9，P=0．003）均优于术前水平。疗效优良率为90．5％，合并其他手术的患者优良率与仅行后踝关节镜的患者差异无统计学意义（86．4％ vs 95．0％，P=0．608），2例患者足跟或足底皮肤仍有局部麻木感。结论后踝关节镜术后中期临床效果良好，疼痛和关节功能明显改善，有合并损伤的患者可与其他手术同时进行。

Objective Study the mid-term outcomeby following up and analyzing thepostoperative 3-6 year posterior ankle arthroscopy patients. Methods From June 2009 to December 2012, 45 patients accepted posterior ankle arthroscopic surgery in our institute, of which 42 cases were followed up. The patients included 25 males and 17 females with mean age of （27.1 ± 9.6） years.The preoperative and postoperative VAS score, AOFAS score,Tegner score and joint activity were followed up and compared. Results The average follow-up time was （58.1 ± 12.0） months.The postoperative VAS score （0.8 vs 3.0,P〈0.001）,AOFAS score （93.9 vs 76.5,P〈0.001） and Tegner score （4.9 vs 3.9,P=0.003） were significant improved than the preoperative level. The excellent rate was 90.5%.No significant difference was found between the patients with associated operation and patients only aeceptingposterior ankle arthroscopy （86.4% vs 95.0%, P=0.608）.Two patients still have plantar or heel skin partial numbness. Conelusion After posterior ankle arthroscopy,the mid- term clinical results were satisfactory and the pain and the joint function were improved significantly.The patients with combined injury can be performed with other surgical nrocedures.
