PurposeThe aim of this study was to compare the biomechanical properties between the suture fixation technique and the screw fixation technique for tibial eminence fracture (TEF).MethodsThe current study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PubMed, Embase, and the Cochrane were searched from inception to January 2019 comparing the suture and the screw fixation technique for TEF. The results of the eligible studies were analyzed in terms of stiffness, ultimate failure load, and displacement after the cyclic testing.ResultsSix laboratory studies were included with a total of 114 knees: 57 knees were in the FiberWire suture group and 57 knees were in the single-screw group. The suture group had higher stiffness than the screw group, but there was no statistical difference between these two groups. Ultimate failure load in the suture group was statistically higher than that in the screw group. No statistically significant difference existed in displacement after the cyclic testing between the suture group and the screw group.ConclusionThe FiberWire suture fixation may be biomechanically superior to a single screw fixation in TEF treatment in mature knees regarding ultimate failure load, while no significant difference was found between the two fixations in terms of stiffness and displacement after the cyclic testing.
