Patellar luxation (PL) is one of the most common orthopedic disorders in dogs and a genetic factor is considered to play an important role in the development of PL. Genomic analysis has attempted to identify the genetic markers associated with the development of PL but only suggestive markers have been identified. Carefully selecting breeds with higher incidence rates of congenital PL as well as affected dogs with more severe symptoms are required, but such information remains limited to date.
OBJECTIVE: To assess the relationship between histologic degeneration of cranial cruciate ligaments (CCLs) and severity of synovitis and ligament vascularity.
SAMPLE: CCL and synovium from 59 stifle joints (53 dogs).
OBJECTIVE: To determine the effect of tibial rotation on radiographic tibial plateau angle (TPA) measurement in normal and cranial cruciate ligament (CrCL)-deficient stifles.
STUDY DESIGN: Cadaveric study.
SAMPLE POPULATION: Five pairs of canine cadaver hind limbs with no stifle osteoarthritis.
