You're referring to the tibial plateau leveling osteotomy (TPLO) surgical procedure. Here are the key parameters: 1. Slope angle (倾斜角): The angle between the tibial plateau and the long axis of the tibia, typically set between 5-10 degrees. 2. Rotation angle (旋转角): The angle of rotation of the proximal tibia to achieve proper alignment, usually around 10-15 degrees. 3. Translation distance (平移距离): The distance the proximal tibia is translated to achieve proper alignment, typically around 2-5 mm. 4. Cutting angle (切割角): The angle at which the osteotomy cut is made, usually around 20-30 degrees. 5. Plate angle (板角): The angle at which the TPLO plate is applied, typically around 10-20 degrees. 6. Plate position (板位): The position of the TPLO plate on the tibia, usually medial or lateral. These parameters may vary depending on the individual case and the surgeon's preference.
