Abstract: ［Abstract］ Objective〖HTSS〗To explore the clinical effect of TigerTape ligation fixation through double posteromedial portal under arthroscopy in the treatment of posterior cruciate ligament avulsion fracture.
〖WTHZ〗Methods〖HTSS〗Twenty-two patients with posterior cruciate ligament avulsion fracture were treated with TigerTape line bandage fixation. The treatment method, operation time, complications, postoperative functional training and fracture healing were recorded. The joint stability, extension and flexion were compared to evaluate the joint function before and after surgery.
〖WTHZ〗Results〖HTSS〗The average operation time was 79.52±17.42(60-100) minutes. There was no blood transfusion during and after operation. At two days after surgery, deep vein thrombosis(DVT) was detected in 5 patients in which 3 were in intermuscular veins, 1 was in anterior tibial vein and 1 was in posterior tibial vein. All patients showed no evidence of DVT after 1 week of anticoagulation treatment. No serious complications such as infection, blood vessel or nerve injury, pulmonary embolism or joint stiffness was found. The follow-up duration average 16.91±6.23(6-24) months. The average healing time of fracture was 5.93±1.21(4-8) months. X-ray examination showed that all patients met the clinical healing standard on 6 months after operation. No malunion or nonunion was found. Posterior drawer test was negative. All patients returned to normal activity after operation. After operation the Lysholm score was significantly improved(P＜0.05).
〖WTHZ〗Conclusion〖HTSS〗In patients with posterior cruciate ligament avulsion fracture, TigerTape ligation fixation through double posteromedial portalunder arthroscopy can effectively fix the fracture and restore the knee joint function with the superiority of surgery safety, minimal invasion and faster recovery.
