How long will my dog be in the hospital following TKR surgery?
Most veterinarians keep dogs for one to three days following surgery. In some rare instances, high-risk patients may be hospitalized for longer periods to provide additional assistance or to protect the stability of the new prosthetic joint.
How is the total knee replacement procedure performed in the clinic?
Dog needs to be brought to the clinic for medical examination and assessment of advisability of total joint replacement. If surgery is deemed necessary, an anesthesiologist’s consultation is needed in order to schedule a pre-surgery evaluation. If no contraindications to general anesthesia exist, the date of surgery is scheduled. The owner is requested to wash the dog just before the surgery, and to start giving antibiotics. The dog is to be admitted to the clinic and stay in our in-patient unit for the whole period of surgery and post-operative observation. Duration of in-hospital stay rarely exceeds 7 days. After discharge we will monitor the implant condition by X-ray on days 14, 30, 60, and then 6 months after surgery; thereafter, follow-up orthopedic exams are performed yearly.
How to make a right decision pro or contra total joint replacement?
Total joint replacement is not an urgent surgery, so decision should be balanced and based on specialist advice.
How do I know that my dog needs joint replacement?
Failure of medical treatment and irreversible joint damage.
Is it possible to manage joint diseases without joint replacement?
Most orthopedic diseases can be successfully managed without prosthetic repair.
How do I know that my dog has a joint problem and needs to be examined by veterinary orthopedist?
Gait disturbances, rapid fatigue and reluctance to move as it normally would, for example to jump or walk upstairs, are all the obvious signs of an orthopedic problem.
Is it possible and necessary to replace a joint at an early stage of progressive joint disease?
No; joint sparing treatment to the fullest extent possible should be attempted.
Is total joint replacement a last-resort option, when other treatment methods have failed, or a treatment option for joint disease?
Yes, it is a last-resort option, when salvage of native joint is unfeasible, and conservative treatment is ineffective.
How long will the implant last?
There is not enough data beyond 5 years of follow-up to provide a definitive answer to this questions. In humans, TKR implants are expected to last more than fifteen years. Implant survival depends on long-term stability of the implant, maintenance of a smooth articulation between the components, and the patient activity level. We expect that the implants will survive for the lifetime of a dog.
What is the success rate for the canine TKR procedure?
Available data indicates that TKR is effective in providing pain-free function in dogs with end-stage arthritis. As part of the ongoing clinical trial of canine TKR, BioMedtrix is actively collecting clinical data. The results from this prospective study will provide a clear picture regarding the overall long-term success rate for TKR in dogs. Initial results of the clinical trials have been published. It is our expectation that success rates will be similar to those seen with total hip replacement (THR) in dogs which are widely cited as being successful.
What is the typical recovery time after TKR?
Recovery depends on the severity of the pre-operative arthritis and can be improved by following a structured post-operative rehabilitation program. Activity is limited for two to six weeks following surgery. Dogs usually use the leg the evening of surgery, and most are doing very well in six months.
How common is TKR in dogs?
The canine TKR system was introduced in 2005. Since that time, over 300 surgeries have been preformed throughout Australia, Europe, the United States, and Canada. We anticipate demand for this surgery will increase significantly each year.
Are there reasons my dog shouldn't have TKR surgery?
If your dog’s arthritis is effectively controlled with drug therapy or other methods, TKR surgery is not likely to be recommended. It is important to recognize that TKR may be indicated if medical therapies eventually become ineffective.
Pre-existing infection is a contraindication to TKR surgery. Additional reasons why surgery may not be recommended include lameness associated with arthritis in other joints, neurological disease, and previous amputation of a forelimb or opposite hind limb. These conditions do not necessarily preclude TKR but the final decision is made on a case-by-case basis.
What are the risks of TKR?
The most significant risks associated with TKR surgery are anesthesia, implant loosening, and infection. Infection is a rare but potentially devastating complication of any surgical procedure. The risk of loosening is also rare. The risks associated with anesthesia are very low as a result of preoperative screening, modern drug use protocols, and intraoperative monitoring. Your veterinary team will do everything possible to minimize the risks.
What are the benefits of TKR?
The primary goal of TKR surgery is to restore pain-free function. In most cases, it is possible to restore the joint function to a level similar to that of a healthy knee joint. Dogs that have had successful TKR surgery do not require long-term medical management. In addition to significant cost savings, this will eliminate the potential problem of long-term complications associated with chronic use of anti-inflammatory drugs.
What does TKR surgery entail?
The knee joint is exposed through an incision on the side of the knee. The joint surfaces are replaced, stability of the knee ensured, and the surgeon verifies that the knee moves smoothly through a full range of motion. A light dressing is applied over the incision in the early post-operative period.
What is canine total knee replacement (TKR)?
TKR is a surgical procedure in which damaged joint surfaces are replaced with a prosthesis designed to restore pain-free knee function.
The replacement joint consists of a metal component attached to the end of the femur and a polyethylene component attached to the tibia. The components create new bearing surfaces that mimic normal movement of the joint.
Why has TKR been recommended for my dog?
TKR is recommended because it is an option for alleviating the pain and/or disability associated with knee arthritis. Many dogs that do not respond to standard medical or surgical management can benefit from TKR.
To determine if TKR is the appropriate option, schedule a consultation with your veterinarian. This is a surgical procedure but, for the right patient, surgery can greatly improve quality of life.
