SUMMARY:

The joint has synovial fluid, which serves to lubricate and prevent contact between the joint surfaces, as well as a joint capsule, composed of hyaline articular cartilage that covers the ends of the bones involved in the joint, and the subchondral bone (KÖNING and LIEBICH, 2011; PIERMATTEI et al., 2009). This structure ends up allowing the joint to develop, together with other elements of the appendicular skeleton, the function of promoting mobility and stability for the transfer of load between the bones (SCHULZ, 2008). The knee is one of the most important joints within the dynamics of the ambulatory movement in dogs and is formed by the femorotibial and patellofemoral joints, both sharing the same composite synovial cavity (more than two bones), which allows movement restricted to flexion and extension. The condyles of the femur attach to the menisci and these slide over the tibial plateau, cranially in extension and caudally in flexion (DYCE et al., 2004; KÖNING and LIEBICH, 2011). The knee joint is also composed of: tendons, intra-articular ligaments (cruciate ligaments) and collaterals that help with external joint support and fat pads that help reduce stress during overload (SCHULZ, 2008). The muscles, ligaments, joint capsule and bone structures involved in the joint limit the range of motion of the joints, preserving them (PIERMATTEI et al., 2009) Rupture of the cranial cruciate ligament (RLCCr) can affect animals of any breed, sex or age (HULSE and JOHNSON, 2002), but this condition becomes more frequent in larger animals (DEJARDIN et al., 1998). Injuries to the CrCL can be caused by avulsion of one of the ends of the ligament, called traumatic, or spontaneously, classified as non-traumatic (MATERA et al., 2007). One third of animals that present the non-traumatic form of rupture present rupture of the contralateral limb, generally after around eight months (DOOM et al., 2008). There is a consensus that the modality of choice for obtaining images of the knee is magnetic resonance imaging (MRI), however, according to Vekens et al., (2019), high-frequency ultrasound is recommended for the detailed evaluation of canine CRL, menisci and meniscotibial ligaments cranial lesions, mainly due to MRI being a less accessible technique within veterinary medicine. The ultrasound technique, when associated with computed tomography (CT), can be an alternative for evaluating the intercondylar notch, obtaining sensitivity and specificity similar to magnetic resonance imaging for detecting meniscal injuries and much higher than digital radiography (Lewis et al., 2008; Vande et al., 2002). Therefore, the present study aims to evaluate the contralateral joint of osteotomized animals, through radiography, ultrasound and computed tomography examinations in search of early findings of injury to the knee joint structures.
