The osteotomies of the proximal portion of the tibia has been used in recent years as a treatment of the cranial cruciate ligament rupture (RLCCr).Recently developed technique of triple osteotomy of the tibia (TTO) and its analysis based on clinical and radiographic. twelve members of pelvic cadavers divided into two groups: TTO (GI) and TTO modified (GII) were subjected to biomechanical testing and was evaluated by radiographic images and photographs at different times: LCCr effect of intact without load (M0), LCCr intact under load of 30% by weight (M1), LCCr sectioned under load of 30% by weight (M2, TTO void load (M3), TTO a load of 30% of the weight of the (M4) and release of the medial meniscus under load of 30% by weight (M5). In different times were evaluated: the cranial displacement of the tibia on the femur, the angle of the tibial plateau (APT), the angle of the patellar tendon (ATP), the rotation of the tibia in both groups it became evident after the M2 But doing the same TTO no significant difference between M2 and moments later. APT significant difference after the TTO in GII, but there was no statistical difference between groups .O ATP only significant difference after RLCCr and then the M3, there was no difference between times and between groups. A tibial rotation significant difference between groups from the M3, which in GII tibial rotation was significant. The displacement of the medial meniscus was significant only in the M5 and not made difference between groups. The two techniques, not remedial TTO the cranial displacement of the tibia after resection of LCCr, and release of the medial meniscus did not significantly influence the stability of the stifle in this biomechanical study.
