探讨应用克氏针辅助定位法，快速建立距下关节镜通路的可行性，以及随访距下关节镜的近期手术疗效，为进一步推广应用提供依据。

随访2011年10月至2019年7月在西南医院关节外科应用克氏针辅助定位法快速建立距下关节镜通路并实施距下关节镜手术患者26例。记录围手术期并发症，采用配对t检验比较术前与术后末次随访的踝关节视觉模拟疼痛(VAS)评分、美国足踝骨科协会踝与后足(AOFAS)评分的变化，记录距下关节骨性融合时间。

本组随访全部患者26例，随访时间(45±26)个月。患者术中和术后未出现血管神经损伤表现，术后未出现切口感染、愈合不良以及深静脉血栓形成的并发症。实施关节镜下清理术22例，与术前VAS评分(6.8±1.1)分比较，末次随访时VAS评分降至(1.3±0.8)分(t＝24.783，P<0.001)；AOFAS术前为(68.2±13.0)分，术后为(91.7±6.9)分(t＝-13.504，P<0.001)。实施关节镜下融合术4例，骨性融合时间(12.0±1.6)周。

应用克氏针辅助定位法，可以快速建立距下关节镜通路，视野清晰，可满足常规距下关节镜清理术或者融合术。该技术简单易行，尤其适用于距下关节镜操作较少的医生。

To explore the feasibility of using the Kirschner wire-assisted positioning method to rapidly establish the subtalar arthroscopic portal, and conduct follow-ups to investigate the short-term efficacy of the subtalar arthroscopy to provide evidence for its further promotion and application.

The patients who underwent conventional subtalar arthroscopic debridement or arthrodesis using Kirschner wire-assisted positioning method at the Center for Joint Surgery of Southwest Hospital from October, 2011 to July, 2019 were followed up. The perioperative complications were recorded; the paired t test was used to analyze the preoperative and postoperative visual analogue scale (VAS) and the American Orthopedic Foot and Ankle Society (AOFAS) scores; the bone fusion time of the arthrodesis group was recorded.

A total of 26 patients were followedup, with a follow-up time of (45±26) months. There was no vascular nerve injury intraoperatively, and no complications of incision infection, poor healing and deep vein thrombosis postoperatively. Twenty-two patients underwent arthroscopic debridement. Compared with the preoperative VAS score (6.8±1.1), the VAS score at the last follow-up decreased to (1.3±0.8), and the difference was statistically significant (t=24.783, P<0.001). the AOFAS score were (68.2±13.0) points before the surgery, and (91.7±6.9) points after the surgery (t=-13.504, P<0.001). Four cases underwent arthroscopic arthrodesis, and the bone fusion time were(12.0±1.6)weeks.

The application of the Kirschner wire-assisted positioning method can rapidly establish the subtalar arthroscopic portal with a clear field of vision, which meets the conventional requirements for subtalar arthroscopic debridement or arthrodesis, which is of great value for inexperienced surgeons performing foot and ankle arthroscopy.
