Many canines suffer severe, grade I-IV, medial patella luxation causing a persistent lameness, severely reducing the quality of life for the dog (Linney et al 2011). For these patients surgical intervention is recommended to alleviate these symptoms. The procedure used to do so is a distal femoral osteotomy (DFO). This procedure allows for correction of torsion in the femur and quadriceps mechanism, and frontal plane abnormalities at the same time. The present study aims to describe the long-term outcome and related complications of 32 DFOs, without concomitant Cranial Cruciate Ligament rupture (CCLR), in a large private practice referral hospital based on data provided by one board certified orthopedic surgeon. We hypothesize that patients having DFOs at Metropolitan Veterinary Hospital (MVH) to alleviate medial patella luxation (MPL) will have a good to excellent long-term outcome with very minimal complications. Canines with any concurrent CCLR, DFOs performed for any other disease process other than MPL, any severe or uncontrolled systemic disease, or a concurrent history of previous ipsilateral stifle surgery were excluded from the study and data sets. Any complications resulting will be described as major: indicating additional surgery required, or as minor: indicating non-surgical intervention. All patients in the present study were described as not having major complications. Results gathered confirmed what was presented in previous data. Modern MPL surgical techniques provide great stability and overall a fantastic long-term outcome as confirmed by this study. This research also addressed an information gap that was forming due to the lack of recent research into this topic providing invaluable new information.
