Abstract：Objective To investigate clinical effects on the treatment of tibial avulsion fracture of the posterior cruciate ligament with anchor screws. Methods Twenty-one patients of tibial avulsion fracture of the posterior cruciate ligament were treated with anchor screws. All patients had been applied postoperative plaster immobilization of the knee at 30° flexion for 4 weeks. Functional exercises of the knee were conducted after the removal of the plaster. Results All patients were followed up for 7 - 11 months with the average of 9.2 months. The Lysholm score preoperatively and 6 months postoperatively were ( 59.4 ± 8.1 ) point, ( 86.4 ± 9.1 ) point, respectively. Differences were statistically significant ( P < 0.05 ). The range of motion of the knee preoperatively and 6 months postoperatively were ( 86.8 ± 13.5 ) °, ( 139.1 ± 8.9 ) °, respectively. Differences were statistically significant ( P <0.05 ). IKDC score preoperatively and 6 months postoperatively were ( 50.6 ± 6.1 ) point, ( 92.8 ± 5.5 ) point, respectively. Differences were statistically significant ( P < 0.05 ). Conclusions Internal fixation with anchor screws is safe and effective in the treatment of tibial avulsion fracture of the posterior cruciate ligament. Reliable internal fixation is effective in the early reconstruction of the knee stability and recovery of knee functions.
