Objective To compare the outcomes of open reduction through double row absorbable anchor bridge suture with hollow nails for acute posterior cruciate ligament (PCL) avulsion fracture. Methods From May 2015 to May 2019, 35 patients with acute PCL avulsion fractures were treated by open reduction through double row absorbable anchor bridge suture or hollow nails. There were 15 cases in double row absorbable anchor group and 20 cases in hollow nails group. The operation time, incision length, postoperative ambulation time, hospitalization expenses, healing time of fracture and Lysholm score of patients at the last follow-up were compared between the two groups. Result All the patients in both group had operation perfromed smoothly without serious complication. The operation time in double row absorbable anchor group was (77.33±9.88) min which was longer compared to (59.75±7.86) min in the hollow nails group (p<0.05). The hospitalization expenses indouble row absorbable anchor group was (28132±2096)yuan which was higher compared to (15904±1113) yuan in the hollow nails group (p<0.05).The postoperative ambulation time in double row absorbable anchor group was (2.07±0.70) d which was shorter compared to (3.80±1.64) d in the hollow nails group (p<0.05). There were no significant difference between the two groups in incision length, healing time of fracture and Lysholm score of patients at the last follow-up (p>0.05). Conclusion Both open reduction through double row absorbable anchor bridge suture and hollow nails for acute PCL avulsion fracture have good clinical result. Double row absorbable anchor bridge suture had advantage of reliable fixation and shorter postoperative ambulation time incision length, however, hollow nails fixation had advantages of less operation time and lower hospitalization expenses.
