Abstract

Cranial Cruciate Ligament (CCL) rupture and Medial Patellar Luxation (MPL) are common orthopedic conditions affecting the canine stifle joint, particularly in small and toy breeds and larger athletic dogs. When these conditions occur together, they pose a significant surgical challenge due to the combined biomechanical abnormalities. Traditional surgical approaches, such as Tibial Plateau Leveling Osteotomy (TPLO) for CCL insufficiency and corrective procedures for MPL, do not adequately address both conditions simultaneously. A novel modification of TPLO, known as TPLO-M, has been developed to address this challenge. This technique involves lateralizing the distal tibial fragment after a crescentic osteotomy and applying a standard TPLO plate supplemented by a stack plate, allowing controlled lateralization of the tibial tuberosity and restoring patellar tracking. This approach reduces surgical inventory, lowers costs, and shortens operative time. The results of 17 cases, with concurrent CCL rupture and Grade III MPL, demonstrate excellent patellar tracking, stable fixation, rapid recovery, and a reduced need for multiple surgeries. The proposed TPLO-M technique is reliable, economical, and biomechanically a sound advancement in small animal orthopedic surgeries.
