Abstract：Objective To study the surgical method and clinical results of knee arthroscopy with double ETHIBOND sutures in the treatment of tibial avulsion fractures of the posterior cruciate 1igment ( PCL ).Methods From June 2014 to October 2015, a total of 18 patients with PCL tibial avulsion fractures who were treated with double ETHIBOND sutures under knee arthroscopy were enrolled. There were 10 males and 8 females, whose mean age was ( 32.5 ± 8.7 ) years old. Anteromedial, anterolateral, posteromedial and high posteromedial portals were built before the operation, which aimed to explore the knee joint. Both the avulsed bone block and the tibia bone bed were refreshed via the double posteromedial portals. The 2 bone tunnels ( 4.5 mm in diameter ) was completed with the assistance of PCL director drill guide. Double ETHIBOND sutures were used during the reduction to ifx the avulsed bone by double posteromedial portals. The sutures were pulled out through the 2 bone tunnels and tied in front of the tibia. Reduction and healing of the avulsion fractures and mobility degree of the knee were observed after the operation. Lysholm and the international knee documentation committee subjective knee form ( IKDC ) scores were calculated to evaluate the functional recovery of the knee.Results All the cases were followed up from 8 to 24 months, with an average of ( 14.2 ± 3.2 ) months. All the avulsion fracture healing was achiveved without displacement according to the X-ray and CT scanning, and the average healing time was 2.5 months. The posterior drawer test showed negative results in all the cases. The knee extension was unlimited, and 15° lfexion limitation was found in 1 case due to delayed rehabilitation. The average range of lfexion was ( 135.5 ± 3.5 ) °. The average Lysholm scores were increased from ( 37.8 ± 3.5 ) points to ( 95.6 ± 3.2 ) points (P < 0.001 ), and the average IKDC scores were increased from ( 54.7 ± 6.5 ) points to ( 95.2 ± 4.5 ) points (P < 0.001 ). The differences were statistically signiifcant.Conclusions The method of kneearthroscopy with double ETHIBOND sutures in the treatment of tibial avulsion fractures of the PCL is minimally invasive, safe and reliable. It is helpful for early postoperative rehabilitation. The stability of the knee can be achieved without secondary operation. In conclusion, the curative results of this method are satisfactory.
