The optimal surgical treatment of isolated tibial avulsion fractures of the posterior cruciate ligament (PCL) remains controversial. The purpose of this study was to report preliminary results of a novel surgical approach to isolated PCL avulsion fractures by a minimally invasive postero-medial approach with suture anchors.
Outcomes were retrospectively analyzed in 16 patients with isolated tibial avulsion fractures of the PCL treated with this approach.
Length of surgery ranged from 20 to 40 min (mean, 28 min). Patients were followed-up for 4 to 36 months (mean, 18 months). X-rays showed that satisfactory reduction and bony healing was achieved in all cases. Excellent and good outcomes were reported by 15 and 1 patient respectively with the Lysholm score system.
This minimally invasive postero-medial approach, with minimal but sufficient exposure and effective fixation, may be suitable for the treatment of isolated tibial avulsion fractures of the PCL. More detailed and longer follow up of these patients is needed before definitive conclusions on efficacy can be reached.
后交叉韧带（PCL）孤立性胫骨撕脱骨折的最佳手术治疗方法仍存在争议。本研究的目的是报告一种通过微创后内侧入路使用缝线锚钉治疗PCL孤立性撕脱骨折的新手术方法的初步结果。
回顾性分析16例采用该方法治疗的PCL孤立性胫骨撕脱骨折患者的结果。
手术时间为20至40分钟（平均28分钟）。患者随访4至36个月（平均18个月）。X线显示所有病例均实现了满意的复位和骨愈合。根据Lysholm评分系统，15例患者结果为优，1例为良。
这种微创后内侧入路，暴露最小但足够，固定有效，可能适用于治疗PCL孤立性胫骨撕脱骨折。在得出关于疗效的明确结论之前，需要对这些患者进行更详细和更长时间的随访。
