Not all who have knee problems need to undergo knee replacement. Most of the time, only patients with severe destruction of the knee joint or osteoarthritis end up having their knee replaced. The procedure is medically known as Total Knee Replacement surgery. In this procedure, the defective knee will be replaced with an artificial one. The diseased or injured joint will be replaced with plastic and metal parts which function normally and last long enough for the patient to enjoy doing normal activities again.

Total Knee Replacement is a popular procedure not only for osteoarthritis patients, but also to those who have devastatingly injured their knee. Despite the success and innovativeness of this procedure, some people are still wary of its effects. Some patients are still concerned about the pros and cons of Total Knee Replacement.

But it is not only this that they are worried about. There are reports that say once you have undergone TKR on your one knee, you will likely undergo another procedure on your other knee. Patients raise concern that once you have had one knee replaced, there is a high chance that your other knee will need replacement too. So the question that needs to be answered is this: do both knees end up being replaced? Is this a fact or just a myth? Let us find out if there is any truth to this.

To answer the question, let us take a look into a particular study conducted on the subject. A population study spanning 40 years was conducted. This question was addressed to the TKR candidates: if you had one knee replaced, what are the chances that the other knee will also be replaced through Total Knee Replacement surgery? Based on the data studied, the general finding is this: there is 45% chance that the other knee will be replaced within 11 years after the first knee replacement. In the study, the data of 2,000 total knee patients, spanning from 1969 to 2008, were analyzed. The results show that out of the 2,000 patients who underwent one knee replacement, 809 had their other knee replaced within 11 years after the initial knee replacement procedure. In fact, most of the patients underwent the second knee replacement surgery within 10 years.

Now going back to the question, the answer is yes, it is a TKR surgery fact that both knees could end up being replaced. But this does not mean that TKR as a procedure is not working. It just goes to show that once one knee has encountered an injury or another problem that needs surgery; there is higher chance that the other knee will also encounter the same fate. Still, this does not take away the fact that TKR is an innovative and important procedure. And if you indeed end up having your other knee replaced too with an artificial one, you can still count on the procedure just as you had during the first surgery. As long as it is done right and by the right professional, there is really nothing to worry about.

Total Knee Replacement Fact: Obesity Puts Patients at Risk

obesity and total knee replacement

Much is said about Total Knee Replacement. While many agree that it is a perfectly safe procedure, there are those who say that the surgery can be risky. One of the most common factors that increase the risk for knee replacement is obesity. There is a circulating belief that people who are obese are not fit to undergo TKR. There is higher risk for complications for patients who are obese, they say. How true is this and if so, what are the possible serious complications? Let us find out.

Let us take a closer look into this study conducted by Mayo Clinic which was published in 2016. The study seeks to the address the following question: Is Total Knee Replacement a more risky procedure in patients with high body mass index (BMI)? Luckily, this was answered in the same study.

The study used and reviewed the data of 22,000 patients who underwent Total Knee Replacement. The average BMI of the patients is 31. Out of the 22,000 patients included in the study, 5,500 have a BMI above 35. Based on the results of the study, there was an increased rate of repeat knee surgery (including revision total knee replacement surgery) as well a striking increase of knee joint infection, a serious complications in the morbidly obese group (BMI 35-40).

Complications arose following the Total Knee Replacement among the patients belonging to this group. This answers the question as to the complications that obese patients might encounter after undergoing TKR.

However, in the same study, it has been noted that the risk for complication can be minimized by delaying surgery until obesity and other modifiable risk factors are reversed. While obese patients are at risk for complications when undergoing the procedure, the case is not totally hopeless. In fact, the case can be remedied and these patients can still continue with their treatment with less risk. The risks can be minimized through best practices. This calls for experienced and reliable professionals. If the surgeons employ best practices and proven strategies, they can maximize patient outcomes and surgical success, as well as minimize risk for serious complications among obese patients. In other words, the key to lowering or totally eliminating the risk for such patients during and following TKR is to have the procedure conducted only by trusted and proven professionals.

So if you are obese and you have knee problems, don’t consider yourself as a hopeless cause. You can still have your knee issue fixed without having to worry about serious complications following the knee replacement. As already said, it’s just a matter of employing best practices With the right preparation and right measures before, during a and after the procedure, you will have a successful TKR operation. To reiterate, the key to a successful surgery is a reliable, trustworthy and experienced surgeon.
