Since its introduction, the posterior transseptal portal has been widely employed to access lesions in the posterior compartment. However, special care should be taken to avoid neurovascular injuries around the posteromedial, posterolateral, and transseptal portals. Most importantly, popliteal vessel injury should be avoided when creating and using the transseptal portal during surgery. Purpose of the present study is to describe how to avoid the neurovascular injuries during establishing the posterior three portals and to introduce our safer technique to create the transseptal portal. To date, we have performed arthroscopic surgeries via the transseptal portal in the posterior compartments of 161 knees and have not encountered nerve or vascular injury. In our procedure, the posterior septum is perforated with a 1.5-3.0-mm Kirschner wire that is protected by a sheath inserted from the posterolateral portal and monitored from the posteromedial portal to avoid popliteal vessel injury.展开更多
目的 比较关节镜下经后内侧双通道入路与后内侧单通道入路治疗腘窝囊肿的临床疗效。方法 回顾性分析连云港市第一人民医院关节外科2019年1月至2021年1月收治的手术切除的腘窝囊肿患者53例。将患者分为两组:单通道组25例,双通道组28例。...目的 比较关节镜下经后内侧双通道入路与后内侧单通道入路治疗腘窝囊肿的临床疗效。方法 回顾性分析连云港市第一人民医院关节外科2019年1月至2021年1月收治的手术切除的腘窝囊肿患者53例。将患者分为两组:单通道组25例,双通道组28例。单通道组病例采取传统关节镜下单通道入路治疗腘窝囊肿;双通道组病例采取关节镜下双通道入路治疗腘窝囊肿。记录两组患者的手术时间、囊肿最终结局、手术并发症,以及术前、末次随访的Lysholm评分和Rauschning and Lindgren评分。结果 最终纳入53例病例,随访时间11~13个月,平均随访时间为(12.70±0.35)个月。双通道组手术时间长于单通道组,差异具有统计学意义(P<0.05)。单通道组复发率高于双通道组,差异具有统计学意义(P<0.05)。两组术后并发症发生率比较,差异无统计学意义(P>0.05)。两组组内术前、末次随访的Lysholm评分比较,差异具有统计学意义(P<0.05);两组间末次随访Lysholm评分比较,差异无统计学意义(P>0.05)。两组组内术前、末次随访的Rauschning and Lindgren评分比较,差异具有统计学意义(P<0.05);末次随访Rauschning and Lindgren评分显示双通道组的功能评价优于单通道组,差异具有统计学意义(P<0.05)。结论 关节镜下经后内侧双通道入路治疗腘窝囊肿较传统单通道入路是一种具有更低复发率,更好的短期疗效,且同样安全的手术方法。展开更多
