The TPLO procedure stabilizes the knee by leveling the tibial plateau. In the example of a car parked on a hill, the hill is leveled thus eliminating the need for the brake previously provided by the cruciate ligament.
Radiographs of the knee are taken prior to surgery. Using specific landmarks, the surgeon will measure the tibial plateau angle (slope) and accurately and precisely determine the amount of rotation that is needed to reduce the angle to between 5 and 8 degrees.
During the TPLO procedure, the surgeon will make a curved cut (osteotomy) in the top of the tibia and rotate the segment so that the load-bearing surface of the tibia is between 5 to 8 degrees. A plate is then applied to hold the tibia in this position and allow for the bone to heal. Dr. Sherman Canapp intvented the plate used by VOSM.
