To investigate the effectiveness of arthroscopically assisted treatment of acute tibial insertion avulsion fracture of the posterior cruciate ligament (PCL) via posteromedial incision.
Between January 2010 and January 2012, 22 patients with acute tibial insertion avulsion of the PCL underwent arthroscopic reduction and fixation via posteromedial incision. There were 14 males and 8 females with an average age of 32 years (range, 18-48 years). The injury causes included traffic accident injury in 14 cases, sport injury in 4 cases, and falling injury in 4 cases. The disease duration ranged from 7 to 16 days (mean, 10 days). Of 22 patient, 14 had simple PCL injury, 6 had PCL injury with meniscus injury, and 2 with cartilage injury. The results of posterior drawer test were positive in all patients. The preoperative Lysholm score was 51.1 +/-3.4.
All incisions healed by first intention without infection, deep venous thrombosis of lower limbs, or vessel and nerve injuries. All patients were followed up 12-24 months (mean, 18.4 months). X-ray films showed that all fractures healed with the healing time of 2-4 months (mean, 3 months). The Lysholm score was improved to 96.0 +/-2.2 at 6 months after operation, showing significant difference when compared with preoperative score (t=43.020, P=0.000).
Arthroscopically assisted treatment of acute tibial insertion avulsion fracture of the PCL via posteromedial incision is a safe, easy, and effective method.
探讨关节镜辅助下经后内侧切口治疗后交叉韧带（PCL）胫骨止点急性撕脱骨折的疗效。
2010年1月至2012年1月，22例PCL胫骨止点急性撕脱伤患者接受关节镜下复位及经后内侧切口固定治疗。其中男性14例，女性8例，平均年龄32岁（18 - 48岁）。损伤原因包括交通事故伤14例，运动伤4例，坠落伤4例。病程7 - 16天（平均10天）。22例患者中，单纯PCL损伤14例，PCL损伤合并半月板损伤6例，合并软骨损伤2例。所有患者后抽屉试验结果均为阳性。术前Lysholm评分为51.1±3.4。
所有切口均一期愈合，无感染、下肢深静脉血栓形成或血管神经损伤。所有患者均获随访12 - 24个月（平均18.4个月）。X线片显示所有骨折均愈合，愈合时间为2 - 4个月（平均3个月）。术后6个月Lysholm评分提高至96.0±2.2，与术前评分比较差异有统计学意义（t = 43.020，P = 0.000）。
关节镜辅助下经后内侧切口治疗PCL胫骨止点急性撕脱骨折是一种安全、简便、有效的方法。
