The treatment of acute posterior cruciate ligament tibial avulsion fracture after the medial knee approach

目的:探讨选择膝后内侧直切口手术入路、采用抽出钢丝法固定治疗急性后交叉韧带胫骨止点撕脱骨折的疗效。方法:对28例急性后交叉韧带胫骨止点撕脱骨折患者,选择膝后内侧直切口手术入路、采用抽出钢丝法固定。结果:本组28例患者经平均14.5个月的随访,伤口均甲级愈合,骨块位置良好无再移位,均骨性愈合。膝关节稳定性好,后抽屉试验阴性。按Lysholm疗效评定标准进行综合评分为(93.4±1.6)分,均为优。结论:选择膝后内侧直切口手术入路、采用抽出钢丝法固定治疗急性后交叉韧带胫骨止点撕脱骨折,显露容易,创伤小,复位固定可靠,费用低廉,在基层医院也可以开展。

Objective： To investigate the choice of the medial knee straight after incision surgical approach, the use of law out of wire fixation for the treatment of acute posterior cruciate ligament tibial avulsion fracture. Methods： 28 cases of acute posterior cruciate ligament tibial avulsion fracture patients, choice of straight medial incision after knee surgery ap- proach, the use of law out of a fixed wire. Results： 28 cases of patients in this group by an average of 14.5 months of followed-up, wound healing were Class A, good location without bone displacement, all of the healing bone. Knee stability after the drawer test negative. Lysholm effect in accordance with a comprehensive assessment of the standard score of （93.4± 1.6） were excellent. Conclusion： Straight medial incision after knee surgery approach, the law out of wire fixation for the treatment of acute posterior cruciate ligament tibial avulsion fracture, revealing easy, trauma reduction and fixation reliable, low-cost and grass-roots hospitals can also be carried out.
