Summary
The purpose of this study was to compare a trochlear block recession to a rotating
dome trochleoplasty, a novel technique for the correction of patellar luxation in
small animals. Twenty-eight limbs were used from 14 feline cadavers. With the stifles
in flexion and extension, computed tomography was utilized to compare width and depth
of the trochlea, medial trochlear ridge height, trochlear articular surface area preserved,
patellar contact articular surface area, patellar area covered by the trochlear ridges
and patellar tilt angle. The results of this study demonstrated that a rotating dome
trochleoplasty is superior to a trochlear block recession with regard to medial trochlear
height, trochlear width, trochlear depth and trochlear surface area preservation.
The results of this study support further biomechanical evaluation of this technique
which eventually may lead to clinical trials.
