Abstract

Cranial cruciate ligament rupture is one of the most common pathologies of the knee joint in dogs. It leads to greater knee flexion and subluxation of the tibia throughout the gait cycle, as well as to excessive internal rotation of the tibia during the standing phase. There are many works in domestic and foreign literature on the criteria for choosing the place of osteotomy and the angle of rotation of the osteotomized segment. However, information on the comparative assessment of fixation devices is not provided enough and there is no reliable information on the advantages and disadvantages of blocked compression and dynamic compression plates for osteofixation when performing rotary osteotomy. The process of remodeling of the proximal part of the tibia is completed in subgroup B2 by 45 days. In subgroup A2, in 50% of cases, and in subgroup B2 in 83.3% of cases, the 1st degree of lameness was noted 45 days after surgery. 60 days after surgery, no significant differences between the subgroups were found. The use of proximal tibia metaepiphysis in rotary osteotomy for dogs of medium and giant breeds of Synthes LCP clover leaf allows optimal osteofixation and stabilization of bone fragments, as well as reduction of rehabilitation time.
