Zhang ZZ, Luo H, Zhang HZ, et al. - The present study was performed to correlate the time-zero tibiofemoral contact mechanics among the four different suturing repairs: transtibial pullout suture repair, suture anchor repair, side-to-side repair, and H-plasty repair. Researchers enrolled 24 human cadaveric knees. They tested each lateral meniscus condition (intact, radial tear, and repair) under a 1000-N axial compressive load at 0°, 30°, 60°, and 90° of flexion. They investigated four different repair techniques: transtibial pullout, suture anchor, side-to-side, and H-plasty repair technique. Via Tekscan sensors, tibiofemoral mean and peak contact pressure, and contact area in the lateral and medial compartments were assessed. The outcomes exhibited that the tibiofemoral contact mechanics after adjacent radial tears of the posterior lateral meniscal root were improved to the intact level by H-plasty repair at time-zero. The results of this study demonstrated that the additional vertical mattress sutures act as “stabilizers” to provide a more stable environment in distributing vertical tibiofemoral pressure. It was shown that the other three repair methods also significantly improved lateral tibiofemoral contact mechanics relative to the corresponding tear conditions.
