The Truth About Body Weight And Knee Pain
What Contributes To The Cost
The final hospital bill will depend on many factors, including:
- Number of days you spend in the hospital. This will depend on whether your knee replacement is total, partial, or bilateral.
- Type of implant and surgical approach. This includes the material the implant is made of and the use of any customized surgical instruments or specialized computer technology.
- Preexisting conditions. You might need extra care in the hospital or additional precautions during surgery.
- Time spent in the operating room. If the damage is complex, it can take longer to operate, and this will be more costly.
- Unanticipated care or equipment. If complications occur, you may need additional care.
Your Health Insurance Coverage
Your health insurance coverage will play a big role in how much you pay for your knee replacement. So, we highly recommend taking time to understand your insurance coverage before starting the knee replacement process.
To start, your knee replacement will need to be ordered by a doctor to be covered by insurance. This order lets your insurance company know a knee replacement surgery is necessary to help reduce or manage your knee pain and loss of function.
Your share of costs for these kinds of covered services will depend on your specific health insurance plan, and whether it has copays, deductibles or coinsurance. Costs may also vary depending on what other care costs youve already had to pay during the plan year.
Most insurance brands, including HealthPartners, cover knee replacements. Medicare and Medicaid also cover knee replacements. Usually, most insurances will cover all or a significant portion of the following:
- An initial appointment and evaluation with your orthopedic surgeon
- Appointments you need before surgery, including appropriate testing and diagnostic exams
- The knee replacement surgery, which includes the implant itself, anesthesia and fees for the doctor and operating room
- The care you receive while youre recovering immediately after your surgery
- Physical therapy appointments you might need to help you recover
- Some medical equipment, like safety bars, that will help prepare your home for your recovery
What To Avoid After Knee Replacement
Have you recently had a knee replaced, or are you doing some research before having the procedure? Learning about the recovery process will help you make informed decisions about your routine. When you know what to avoid after knee replacement, you can ensure your knee heals faster and lasts longer.
Depending on your lifestyle, your current everyday tasks might disrupt your healing process. This guide will present a few activities to avoid after knee replacement. Ask your doctor for a more comprehensive list and safe alternatives.
Knee Replacement Surgery Isnt Typically Recommended If Youre Younger Than 50
Recommendations for surgery are based on a patients level of pain and disability. Most patients who undergo a total knee replacement are age 50-80. This is because, knee replacements are not as durable as your own knee and eventually wear out. On average, a total knee replacement lasts about 15-20 years. So if you have the procedure in your 40s, youll likely need another or revision surgery later in life. Whats worse than having to go through another surgery, is that the second surgery is much harder than the first.
The goal of the second knee replacement surgery is the same as the first to relieve pain and improve function. However, revision surgery is a longer, more complex procedure that requires extensive planning, specialized implants and tools, prolonged operating times, and mastery of difficult surgical techniques. Youll also be older and less resilient when you need the second surgery which is why doctors dont usually recommend knee replacement for younger patients.

Components And Material Of A Knee Replacement
Titanium is the metal of choice now for knee implants. My only experience with titanium prior to my TKR was using titanium metal bats when playing softball.
The titanium bats definitely improved the speed of which the ball game off the bat and I no longer enjoyed fielding balls at shortstop.
Titanium is an elemental metal, meaning that it is not man-made. It is an extremely low-density metal and it does not corrode.
It is especially useful for medical applications. Titanium has the lowest strength-to-weight ratio of any metal. Pure titanium is as strong as steel but weighs approximately 45% less.
To construct a prosthetic knee the titanium is melted down and then cast in to components which will eventually form the replacement knee joint.
Weight Management Not A Joint Replacement Knee Replacement Is Not An Easy Way To Weight Lossresearch: Knee Replacement Does Not Help Many People Lose Weight
Many patients are under the assumption that the quickest way to attack their obesity problem is to get a knee replacement. The thinking is that if they eliminate their knee pain they will be able to exercise and lose weight. Surgeons are being told to tell patients that is not true for many obese patients.
Many patients contact us with knee problems. They tell a story that probably sounds a lot like yours:

Can You Damage A Knee Replacement
The answer is yes. Knee replacement complications can result from surgery or a faulty implant. Loosening is one of the most serious complications and pain is the most common one. Loosening can cause bone fractures, instability, and serious falls. Therefore, almost all serious complications require revision surgery.
Dangers Of Doing Certain Exercises Too Soon
Performing movements or exercises that are too intense can increase the chances of loosening or fracturing the bones around the implant.
Pushing too much can also lead to increased pain and swelling around the knee, slowing down the rehabilitation process and making it more difficult to exercise.
Symptoms of pushing too hard during the recovery program might include:
- increased pain
- swelling of the knee or lower leg
- warmth around your knee
If you experience any of these symptoms, its best to back off of the activity and ice your knee for 15 to 20 minutes.
If the symptom persists, call your healthcare provider.

Weight Reduction Strategies Could Potentially Reduce The Need For Knee Replacement Surgery By 31% Among Patients With Knee Osteoarthritis
The simple summary of all the research listed above is this:
Doctors at Oxford University publishing in the journal Arthritis and Rheumatology found that overweight patients are at more than 40% greater risk and obese patients are at more than a 100% increased risk of knee replacement surgery compared to patients with normal weight. Weight reduction strategies could potentially reduce the need for knee replacement surgery by 31% among patients with knee osteoarthritis.
Obese Patients Are More Likely To Require Total Knee Replacement
Doctors in the United Kingdom reported these findings in the journal Maturitis
- There is a proven association between obesity and knee osteoarthritis, and obesity is suggested to be the main modifiable risk factor.
- Obese patients are more likely to require total knee replacement
- It is unclear whether total knee replacement facilitates weight reduction
- Surgery in obese patients is more technically challenging.
- This is reflected in the evidence, which suggests
- higher rates of short- to medium-term complications following total knee replacement, including wound infection and medical complications, resulting in longer hospital stay, and potentially higher rates of malalignment, dislocation, and early revision.

Increased Mobility After 20 Years
According to the Arthritis Foundation, a study done by the Center for Hip and Knee surgery found that after a 20 year follow up of total knee replacements performed between 1975 and 1985 that 95% of patients could walk at least 5 blocks. The average age of the patients in the study was 85. They also found that none of the implants failed after the 20 year mark.1
With most patients in the study having the surgery performed between the ages of 60-80, many can expect to still maintain mobility with unlimited walking, maneuvering stairs, and successfully continue activities of daily living even with the normal age process.
Some patients unfortunately do require a second knee replacement, which is called a revision.Although revisions are often not as successful as a primary knee replacement surgery, reports show that only about 2% of patients require a revision within the first 5 years.

The Type Of Knee Replacement You Need
There are three types of knee surgeries, each with varying levels of complexity and equipment needs:
- Partial knee replacement
- Total knee replacement
- Revision knee replacement
Your orthopedic surgeon will work with you to determine which type of knee replacement will work best for you. At TRIA, our orthopedic surgeons will coach you through the process, and make recommendations based on many factors, including: your age, knee health, bone structure, range of motion, lifestyle, goals and the possibility of needing a revision surgery in the future.
While it may seem a full knee replacement surgery would be the most costly, a revision surgery is actually the most expensive. Total cost of any surgery will depend on complexity of the surgery, among other factors, but a partial knee replacement typically costs anywhere from 10% to 50% less than a total knee replacement.
How Much Does A Knee Replacement Weigh
How much does a knee replacement weigh?
The question was on my mind before and after my surgery so I decided to do some research to find out the answer. I found that theres no single definitive answer.
The average weight of mens knee replacements are 1.12 lbs and womens knee replacements average .76 lbs .
Although the weight of an individual knee replacement varies depending on the size of the knee and the size of the patient, they only weigh a few pounds. Thus, there is no single answer to the question.
In this article I will share the information that I have learned while researching this question.

Activities With A High Risk Of Falling
After a total knee replacement, loss of strength, range of motion, and balance lead to an increased risk of falling. A fall can damage the prosthesis or interfere with the healing process.
A 2018 study found that 17.2 percent of a group of 134 people who had undergone a knee replacement fell at least once within 6 months of their operation. Roughly two-thirds of these falls occurred when walking.
Some lifestyle modifications to reduce your risk of falling include:
- using the handrail when going up and down the stairs
- using a rubber mat or shower chair when showering
- sitting down when putting on shorts or pants
- keeping the floor clear of stray toys, slippery rugs, and other objects that pose a tripping hazard
- avoiding slippery terrains like mud, ice, or wet grass
Research: It Is Unclear Whether Total Knee Replacement Facilitates Weight Reduction Is The Surgery A Barrier To Weight Loss
We do understand that some adult children and spouses may implore their loved ones to get a knee replacement because they have to do something. They are getting heavier and less mobile. In some instances, people can be guilted, into treatment when they perceive that they will be a burden, on their loved ones.
But is knee replacement an answer that will make things better or worse?
An earlier study from the Department of Preventive Medicine, Feinberg School of Medicine, Northwestern University and the Department of Exercise Science, University of South Carolina published in the journal BioMed Central Musculoskeletal Disorders made these observations:
- Most knee replacement patients are overweight/obese, yet are commonly excluded from evidence-based weight loss programs due to mobility limitations and barriers faced around the time of surgery.
- The purpose of this study was to identify knee replacement patient preferences for weight loss programs and qualitatively understand previous motives for weight loss attempts as well as strategies used to facilitate behavior changes.
This study focused on patients who were either scheduled to have knee replacement or had one recently completed within the last 3 months were recruited to participate. Patients completed a brief weight loss program preference questionnaire assessing preferred components of a weight loss program .

Current implant designs recognize the complexity of the joint and more closely mimic the motion of a normal knee
The Impact Of Obesity
Obesity is a major contributor to the increasing need for joint replacement surgery among younger people. Obesity overloads weight-bearing joints, wearing them away, necessitating joint replacement surgery.
And yet, it is precisely these obese patients who tend to have less successful and lasting outcomes after surgery. Functionally, obese patients do not fare as well or recover as quickly as those with normal weight.
Obese patients suffer more complications from joint replacement surgery than normal-weight patients. The risk increases with higher BMI scores. For example, obese patients with BMIs in the 40-to-50 range suffer from post-surgical complications such as infections, wound-healing problems, high blood pressure, sleep apnea, diabetes, and prosthesis failure.
Patients who are obese are also more likely to have other conditions that increase the likelihood of a poor outcome after a joint replacement surgery.

Knee Replacement Surgery Shouldnt Be Your First Line Of Treatment
Even if your knee pain is significant, most doctors will recommend non-operative treatment options before recommending knee replacement surgery. This might include weight loss, an exercise regimen, medications, cortisone or other injection therapies, a minimally invasive surgical procedure, such as a meniscectomy, or bracing.
An Artificial Meniscus May Soon Be Available
If you are suffering from knee pain following meniscus surgery or are without viable treatment options, the NUsurface®Meniscus Implant may provide an alternative option, once it has approval from the U.S. Food and Drug Administration. NUsurfaces design mimics the function of the natural meniscus and redistributes weight across the knee joint. The implant is made from medical grade plastic and, as a result of its unique materials, composite structure, and design, does not require fixation to bone or soft tissues.
NUsurface can potentially address the treatment gap of those who are too old for meniscus repair and too young for total knee arthroplasty. U.S. clinical trials completed enrollment in June 2018, and the company expects to file for U.S. Food and Drug Administration approval soon.

Study Finds Weight Loss Target For Morbidly Obese Before Knee Surgery
By Megan Brooks
3 Min Read
– For morbidly obese patients having knee replacement surgery, losing at least 20 pounds beforehand leads to shorter hospital stays and lower odds of being discharged to a facility, a new study has found.
Surgeons often require or strongly suggest that morbidly obese patients lose weight before total knee arthroplasty , or knee replacement. Many people are told to lose five or 10 pounds before the surgery but we dont actually know how much weight you have to lose for it to lead to a meaningful improvement, Dr. Benjamin Keeney of Geisel School of Medicine, Dartmouth College, in Hanover, New Hampshire, told Reuters Health by phone.
To investigate, he and his colleagues took a look back at 203 patients who were morbidly obese. This meant either they were 100 pounds over their ideal body weight, or their body mass index , a ratio of weight to height, was 40 or more, or it was 35 or more and they had obesity-related health conditions like high blood pressure or diabetes.
In the three months leading up to TKA, 41 percent of the patients lost at least five pounds, 29 percent lost at least 10 pounds and 14 percent lost at least 20 pounds.
When they had the surgery, 27 patients were no longer morbidly obese, although 23 of those were still severely obese .
There were no differences in operative time or physical function improvement. Losing five or 10 pounds did not make a difference for any outcome.
