Abstract:Objective To discuss the effect and method of arthroscopic treatment of tibial intercondylar eminence fracture using steel wire or hollow metal screw.Methods 70 patients with tibial intercondylar eminence fracture were treated by arthroscopic fixation with steel wire or hollow metal screw from October 2014 to March 2020, concluding 45 cases of electric bicycle related injury, 7 cases of slip, 7 cases of fall injury, 3 cases of sport injury, 4 cases of traffic injury and 4 others. The patients were divided into steel wire fixation group (n = 49) and hollow screw fixation group (n = 21) according to the operation method. The patients in the wire fixation group were treated with steel wire, the fractures were fixed with hollow screw in the hollow screw fixation group. There were 24 males and 25 females in the wire fixation group, the average age was (30.76 ± 13.53) years (range 10 ~ 58 years), there were 29 cases of left knee and 20 cases of right knee, There were 11 males and 10 females in the hollow screw fixation group, the average age was (31.90 ± 11.02) years (range, 16 ~ 51 years), there were 13 cases of left knee and 8 cases of right knee.Results All the patients were followed up for 1 year after operation, and bone healed without infection, displacement, wire fracture, epiphyseal malunion and joint adhesion. The Lysholm score of wire fixation group was (51.61 ± 2.83) before operation, and (96.78 ± 1.85) 6 months after operation. The Lysholm score of hollow screw fixation group was (51.52 ± 3.04) before operation, and (96.52 ± 1.91) 6 months after operation, there was no significant difference between the two groups before operation and 6 months after operation (P > 0.05). The operation time of wire fixation group was (76.76 ± 11.57) min, which was significantly shorter than that of hollow screw fixation group (98.62 ± 14.37) min, and the difference was statistically significant (P < 0.05). The length of hospital stay was (10.94 ± 0.94) d in the wire fixation group and (10.62 ± 1.07) d in the hollow screw fixation group, and the difference was not statistically significant (P > 0.05). The hospitalization cost of wire fixation group was (8 964.18 ± 271.04) yuan, which was significantly lower than that of hollow screw fixation group (11 276.95 ± 522.64) yuan, the difference was statistically significant (P < 0.05).Conclusion Intercondylar eminence fracture is a common intra-knee fracture and should be fixed with arthroscope earlier, either with steel wire or hollow compression screw. The steel wire method should be preferred because of its short operation time, low hospitalization cost and convenience of taking out.
