It is VERY common for them to get an epidural but I have a question. Is the epidural a morphine epidural??
Success:
A successful outcome will return your dog to full function on the limb. In my experience, about 90% of the dogs having the TPLO regain normal or near normal function of the limb (full weight-bearing); this information is based on a retrospective survey that we conducted on our patients. The remaining 10% of dogs have concurrent arthritis in other joints of the operated limb or advanced degenerative joint disease in the stifle; most of these dogs in this group are still helped by the surgery.
We have found that most working dogs will return back to full working function.
Dogs that have sustained a blowout fracture of the tibial plateau as a complication of falling after surgery may have residual stiffness or lameness.
Dogs that have been previously operated using another technique frequently are improved with the TPLO surgery, but the outcome may not be as good, versus a virgin knee that has received the TPLO surgery.
Potential Complications: (not to scare you)
As with any surgery, complications may arise. Even though rare, anesthetic death can occur. With the use of modern anesthetic protocols and extensive monitoring devices (blood pressure, EKG, pulse oxymetry, inspiratory and expiratory carbon dioxide levels, and respiration rate), the risk of problems with anesthesia is minimized.
Infection is an unusual complication as strict sterile technique is used during the surgery and antibiotics are administered during the procedure.
Poor healing of the bone can occur if the pet is too active, especially during the first 2 months after surgery. If steroids are given to a pet for reasons such as skin allergies, healing of the bone may be severely impaired. Breakage of plates or screws or backing of screws out of the bone can occur if activity is not limited during the first 2 months. Even after the bone has healed, the soft tissues need to also heal.
If activity is unleashed prematurely, straining of the patellar ligament can occur. Rest and anti-inflammatory medication is used to resolve this problem.
Fracture of the narrow front part of the tibial crest can occur. This is not common, and usually will heal without any surgical intervention. Recovery will be delayed, but the final result still should be very good.
A blow-out fracture of the tibial plateau has been seen in 0.4% of the cases (in a series of 700 cases) at our hospital. The cause of this is due to the dog falling on the stifle after surgery. Reoperation is performed in these cases.
Loosening of the screws with shifting of the slope of the plateau may occur if the pet is not restricted during the healing phase. If the plateau has shifted a significant amount reoperation is performed. This complication is more common in the giant breed dog, as a result we generally use a larger TPLO plate and 8 screws, instead of the standard sized TPLO plate and 6 screws to help prevent this problem.
It has been reported that dogs that have a very steep tibial slope (greater than 35 degrees) are at greater risk of having complications (shifting of the bones, fracturing of bones, loosening of implants). However, once the healing had taken place the function of these dogs too was very good and client satisfaction was usually very good.
A bone cancer can develop in the tibia bone due to the presence of the surgical implants (bone screws and plate), however, this complication is rare. Removal of the plate after healing takes place may help to prevent this complication. Because the formation of this tumor is so uncommon, there is no study available that has truly shown that removing the implants is helpful.
Arthritis usually is present at the time of surgery and will progress to some degree regardless of treatment or no treatment. Unfortunately we cannot reverse the arthritic and degenerative state of the joint, but the surgery may help to minimize the progression of this. I have seen cases receiving the TPLO surgery that have developed minimal arthritis years later, yet other cases have developed a lot of arthritis as seen on x-rays. Just because arthritis may be seen on x-rays does not mean that your dog will be lame on the limb. Warning signs of clinical arthritis include stiffness associated with heavy exercise and cool damp weather. Anti-inflammatory medications are useful to ameliorate a flare-up of arthritis.
Tearing of the meniscus (cartilage pad in the knee) may occur following TPLO surgery and additional surgery would be needed. This complication occurs less frequently following the TPLO versus when other surgical techniques used to stabilize the stifle joint.
Good Luck and Godspeed to you!!
