Tibial Plateau Leveling Osteotomy (TPLO) for Treatment of Ruptured Cranial Cruciate Ligament
TPLO is a very intensive procedure requiring exact precision to treat the cranial cruciate ligament deficiency. Dr.Sran has been performing this procedure as an orthopedic surgeon since 2003 with excellent results. We accept the referrals from other veterinarians across BC, Canada and Washington (WA) state, USA. Waiting period is only 1-2 weeks. Patients are sent home on 2nd day after the surgery. Follow-ups are usually done at the referring hospitals.
What is a Ruptured cranial ligament?
The cranial cruciate ligament (CCL) is a structure in your dog's knee joint, that helps prevent excessive motion between the femur (thigh bone) and the tibia (shin bone). The CCL may become injured, either from trauma or due to dog's natural leg conformation, resulting in a sudden or gradual tear of the ligament. A torn CCL causes the knee joint to be unstable, resulting in joint pain, inflammation and hind leg lameness.
This initiates the development of arthritis and may damage another structure in the knee called meniscus.
Can medication be used to treat a ruptured CCL?
Anti-inflammatory medications prescribed by your veterinarian may help to decrease the pain and inflammation in the knee joint. Strict cage rest and exercise restriction may allow your dog's body to lay down scar tissue, in an effort to increase the stability of the knee. However, small breed dogs (under 4 kg) are typically more responsive to medical management of a ruptured CCL.For medium to large breed with ruptured CCL, especially active dogs or those with other orthopedic problems, surgical treatment is recommended.
What is Tibial Plateau Leveling Osteotomy (TPLO)?
TPLO is a surgical procedure used to treat dogs with ruptured CCL. Developed by the late Dr. Barclay Slocum, the TPLO procedure may be performed by veterinary surgeons who have completed the TPLO training course.The procedure is based on the fact that the top part of the tibia bones normally
sloped, resulting in tendency for the femur to slide backward when the dog stands and puts weight on its knee. The CCL normally holds the femur in place and prevents this motion. But when the CCL has ruptured, the femur can slide back and forth along the sloped tibia, when the dog is standing or walking. The continued motion contributes to pain and degeneration in the knee joint.
Cutting a bone to treat a ligament
A solution to the knee joint instability would be to either replace the torn CCL, or remove the slope in the tibia. The TPLO does the latter: after making a cut in the top part of the tibia, the surgeon rotates this segment of bone until it is almost perpendicular to the ground. To allow the cut bone segments to heal, the tibia is then stabilized with a bone plate and screws. The result is that when your dog stand on its leg, the femur is resting on a flat tibia surface, and there is no longer the sliding motion in the knee.
Can any size of the dog have the TPLO surgery?
The TPLO is recommended for medium to large or giant breeds of dogs, and is limited by the size of the TPLO bone plate.Most dogs greater than 15 Kg in body weight would be eligible for a TPLO.
What is the hospital stay with the TPLO procedure and what follow-up visits are needed?
Dogs are usually discharged next day in the afternoon from the Allwest Animal Hospital following the surgery. Follow-up appointments are usually scheduled at the referring hospital or at our hospital 1 week later for recheck and bandage removal , 2 weeks for recheck and skin suture removal, and in 6 weeks and 10 weeks for radiographs. Your dog may also need weekly Cartrophen shots for 5 weeks post-op.
What is the expected outcome for my dog?
Dogs who have had TPLO surgery are typically bearing some weight on their operated leg within 3 to 5 days following surgery. Your dog will need to have his or her exercise specifically restricted while the bone is healing, usually for 8 to 12 weeks. Physical therapy as well as gradual increase in on-lease activity will be permitted, according to how your dog is recovering. In general, the TPLO procedure for dogs with CCL rupture is associated with a very good early return to leg use: and some research suggests that there is less leg muscle loss and slower progression of knee arthritis following this procedure.
What is the approximate cost of TPLO surgery?
It depends upon few factors like ; Lifestyle, breed and weight of the dog, if x-rays & blood test are done or not, how old is the damage etc. Call or email us for proper estimate for your dog.
