A 2-year-old, castrated male Chihuahua dog was referred for revision surgery for reluxation of the patellafollowing surgery for medial patellar luxation (MPL) of the left stifle joint. On general inspection, the patient showedbilateral hindlimb weight-bearing lameness. On physical examination, bilateral non-reducible MPL was detected throughpalpation. Radiographs revealed bone deformities of both hindlimbs. Computed tomography (CT) was applied for athree-dimensional (3D) printing bone model to establish an accurate surgical plan. The bone plate was pre-contouredover the 3D-printing bone model after execution of corrective osteotomy and sterilized prior to use in surgery. Correctiveosteotomy was performed through a staged, bilateral procedure. The patient showed improvement of limb functionfollowing surgery without reluxation of the patella. The use of 3D-printing bone model for accurate surgical planningof corrective osteotomy appears to be effective in increasing the accuracy of surgery. That may lead to successfulsurgical outcomes.
