Tibial Platue Leveling Osteotomy
TPLO/ Knee Surgery
This surgery is performed to repair the ruptured or torn cranial cruciate ligament (CCLR) or also know as anterior cruciate ligament (ACL). Happens mostly in Large to medium sized active dogs. Normally the stifle (Knee) joint is stabilized by two ligaments called as cranial or anterior cruciate and caudal or posterior cruciate (along with other joint structures). When CCLR happens then the dog starts limping. It can be partial or complete tear. If one leg is affected and the care is not taken early then most likely the other leg gets affected also.
Before surgery, an x-ray of the stifle is taken to measure the angle at the top of the shin bone, called the tibial plateau angle. The goal of the surgery is to reduce this angle so that dynamic joint instability (cranial tibial thrust) is eliminated. During surgery the joint is explored to remove the torn ligament fragments and meniscus if affected. Then the tibial bone is cut and rotated the desired angle and then secured with a surgical stainless steel bone plate and 6-9 bone screws.
Medial Patellar Luxation (MPL)
It's most common in small/ Toy breed dogs. You can notice your pet is missing few steps on the back leg and sometimes limping. When the kneecap does not stay in the femoral groove and luxates mostly towards medial side of the joint. Either the femoral groove is shallow or the abnormal tibial tuberosity positioning. Approximately 50 percent of affected dogs have both knees involved while the other 50 percent has only one knee involved.
MPL has Grade 1,2,3 and 4.
Dogs with Grade 3 or 4 disease definitely should have surgery. If untreated can lead to osteoarthritis and CCLR.
X-rays are done to diagnose then surgery involves either deepening the femoral groove and or tibial tuberosity transposition.
Fracture-
If unfortunately you pet has fracture and confirmed with x-rays then surgery is done to reduce the both fracture ends with the help of plate/screws or pins.
