What Is The Arthrex Ibalance Device
The Arthrex iBalance total knee implant device was approved by the U.S. Food and Drug Administration in 2013 after being fast-tracked through the 510 premarket approval program. This program allows manufacturers to skip rigorous testing by claiming that their devices are substantially equivalent) to already-approved devices. While the Arthrex iBalance device was designed to offer an alternative less intrusive than total knee replacement, more and more patients are reporting serious issues associated with these devices.
Symptoms Of A Failing Knee Implant
Knee implant failure can be caused by a variety of issues including improper care of the implant and a faulty prosthesis. But when do you know if your symptoms are that of an implant failure?
Knee implants can fail gradually over time from abnormal wear patterns without some kind of traumatic injury with obvious cause of damage. Many physical symptoms hip implant patients may experience are related to thinning of the plastic spacers between the bones and metal components of the prosthesis which results in the migration of debris.
Here are some symptoms that may be warning signs of a failing knee implant:
Heat or Warmth in the Knee: After the initial implantation of the artificial joint, and for several months, there will be noticeable warmth in the knee. This should, however, dissipate with time. When it does not, or when it returns, this is an indication of a problem. The level of warmth can be so significant that the skin over the knee turns red and is obviously inflamed and often sensitive.
Pain: Any or all of these conditions can result in pain. If the plastic fragments are present and are large enough, they can actually become lodged in the moving components of the knee, which further harms mobility and causes discomfort. This may manifest as a minor soreness or it can be an acute, severe pain that presents upon motion or as a constant throbbing.
Signs Of Knee Replacement Failure
No one likes to hear the word failure when you are scheduled for surgery. Those of us who made the decision to have total knee replacement did so because we were looking forward to having a functional, pain-free knee.
The last thing we wanted were complications that needed additional medical care or further surgery.
Doctors are not perfect. When I was a youngster, I thought teachers, police and doctors could do no wrong. As I aged, I learned that everyone is human and can make a mistake. Even your surgeon.
There are other factors besides physician error that can cause complications after surgery. In the sections below, I will discuss some things that could go wrong during the knee replacement process.
Remember, there are several things that you can do prior to knee replacement surgery to improve the chances of a successful outcome. Building leg strength, stretching, exercising and weight management are a few pro-active steps you can do to increase the probability of success.
My experience, as well as my discussions with TKR veterans, leads me to believe that the vast majority of knee replacement surgeries have a positive outcome.

Why Do Implants Fail
Wear and Loosening: Properly functioning implants depend on their appropriate fixation to the bone fixation is usually achieved by cementing the implant onto the bone. Some surgeons prefer to use biologic fixation.
Although implants are firmly fixed at the initial knee replacement surgery, they may become loose over time. Friction caused by the joint surfaces rubbing against each other wears away the surfaces of the implant, creating tiny particles that accumulate around the joint. In a process called aseptic loosening, the bond of the implant to the bone is destroyed by the bodys attempt to digest the wear particles. During this process, normal bone is also digested , which can weaken or even fracture the bone.
When the prosthesis becomes loose, the patient may experience pain, change in alignment, or instability. Aseptic loosening is the most common mode of failure of knee implants.
Infection: Infection is a devastating complication of any surgical procedure. In total knee replacement, the large foreign metal and plastic implants can serve as a surface for the bacteria to latch onto, inaccessible to antibiotics. Even if the implants remain well fixed, the pain, swelling, and drainage from the infection make the revision surgery necessary. With current surgical techniques and antibiotic regimens, the risk of infection from total knee replacement is less than 1%.
What If My Knee Replacement Was Installed On The Wrong Knee
In some instances, the wrong sided implant may be used for your knee replacement e.g. a left knee replacement being used on your right knee. This can happen because: the hospital where the surgery was performed does not have protocols for confirming procedure sidedness before the surgery begins similar procedures at this hospital are used for confirming hip components to confirm knee components operating room personnel did not follow a standardized process to confirm knee implant sidedness the operating room staff focused on sizing of the knee replacement and not side.

What Is The Recovery Time After Knee Revision Surgery
It varies, but in most cases, physical therapy will be initiated within 24 hours of the procedure and will continue for up to three months.
Some patients take longer to recover. In some cases, protective weightbearing or limiting the knees range of motion is needed to promote appropriate healing. Therapy will usually continue for up to three months following the surgery. Assistive devices, such as a walker or crutches, will be used early in the convalescence period, and patients will progress to a cane or walking without any assistance as their condition improves.
Choose An Expert Surgeon
Choosing an experienced surgeon can reduce your risk of complications. You should look for a surgeon who has performed hundreds of successful surgeries.
At TRIA, our orthopedic surgeons are considered among the best in the Midwest. One year after surgery, 97 percent of our knee replacement patients reported that they can walk down stairs with little to no difficulty.

Other Common Signs Of Knee Replacement Failure Include:
- Wear and Loosening of Implants: Friction caused by joint surfaces rubbing against each other wears away the surface of the implant causing bone loss and loosening of the implants. However, there are some Symptoms of a Loose Knee Replacement implant that your surgeon will tell you at the time of surgery.
- Infection: Large metal and plastic implants can serve as a surface onto which bacteria can latch.
- Fracture: Fractures around the knee implant that disrupt its stability may require revision surgery.
- Instability: A sensation of the knee giving away may mean that the soft tissue surrounding the knee is too weak to support standing and walking. Improperly placed implants may also cause instability and is one of the common Symptoms of Wrong Size Knee Replacement.
- Stiffness: Loss of range of motion which causes pain and a functional deficit. This is a common Knee Replacement Problems after 10 Years.
We all know that a total Knee Replacement is a complex procedure that requires extensive pre-operative planning, specialized implants and tools, prolonged operating times, and mastery of difficult surgical techniques.
It usually takes longer to perform than the partial knee replacement, says Dr. Ramakant Kumar, Best Doctor forJoint Replacement Patna. Therefore, these knee surgeries must be assessed by a professional orthopedic surgeon like him.
Metal Allergy Or Reaction
If your initial hip replacement was prior to May 2016, your surgeon may have implanted a metal-on-metal device . As these two pieces rub together during everyday activities, they can release microscopic metal particles into your body. This may lead to sensitivity or an allergic reaction in some patients. There are no FDA-approved metal-on-metal hip replacement components available today, but you may need a revision hip surgery if you had one done prior to 2016 and are experiencing symptoms of a problem.
Even if you did not get a metal-on-metal joint, you may still experience sensitivity to metal components that are used in hip and knee replacement joints. It is difficult to diagnose a metal allergy or reaction. However, talk to your orthopedic surgeon if you experience:

Do I Need Revision Surgery
After a knee replacement device has failed, many patients require revision surgery to remove and replace the device in question. Of course, revision surgery brings with it its own risks. Potential complications of revision surgery include:
- Infection
- damage to nerves or blood vessels
- Deep Vein Thrombosis
- Swelling
What Is Partial Knee Replacement
A partial knee replacement is an alternative to total knee replacement for some people with osteoarthritis of the knee. This surgery can be done when the damage is confined to a particular compartment of the knee. In a partial knee replacement, only the damaged part of the knee cartilage is replaced with a prosthesis.
Once partial knee replacement was reserved for older patients who were involved in few activities. Now partial knee replacement is often done in younger people as their recovery is quicker and usually less painful. About 5% to 6% of people with arthritic knees are estimated to be eligible for partial knee replacement.

What Are The Risk Factors For A Failed Knee Replacement
Age, activity level, surgical history and a persons weight can contribute to implant failure. Younger, active patients, people who are obese, and those who have had prior knee surgeries all have a higher increased risk of a failed implant.
Younger, more active patients have a higher rate of revision than older, less active patients because they place more stress on their prosthesis over more time. Obese patients have a higher incidence of wear and loosening because of the increased force of their weight, and they are more prone to infections because of their increased risk of wound healing. Patients with previous knee surgeries are at higher risk for infection and implant failure.
What Are The Signs Of Knee Replacement Failure
The most common symptoms of a failed knee implant are pain, decrease in joint function, knee instability, and swelling or stiffness in the knee joint.
Persistent pain and swelling can indicate loosening, wear or infection, and the location of the pain can be all over the knee or in one particular area . A decline in knee function may result in a limp, stiffness or instability. Patients who demonstrate these symptoms and signs may require revision joint surgery.

What Are The Common Complications That Occur Following A Hip Or Knee Replacement
Hip and knee replacements may require surgical correction or revision for any number of reasons. These include:
- The joint may be unstable
- You may sustain a fracture or other injury
- The artificial joint may become damaged or experience deterioration
- The artificial joint may loosen due to wear
- The site may become infected
What Is Knee Replacement Surgery
is a procedure that involves the replacement of the natural joint with an artificial implant. The first knee replacement surgery was performed in 1968 and now there are over 600,000 knee replacement surgeries performed each year.
Individuals may need knee replacement surgery, also known as total knee arthroplasty, if their joint is damaged by arthritis and injury. In some cases, these conditions can be treated with medications and walking supports. However, other cases may require knee replacement surgery to return patients to their normal activities without pain.
Although joint replacement may sound terrifying, knee replacement is actually a fairly simple four-step surgical implant process, according to OrthoInfo. The surgeon will prepare the bone by removing damaged surfaces and getting them ready for the implant components. Then, the components will be mounted to the bone with specialized press fit or with specialized surgical cement. The undersurface of the patella will then need to be resurfaced and fitted with a plastic button to articulate with the implant surfaces. Last, an insert will be placed between the components to create a smooth surface that helps the joint move.

How Long Does It Take To Recover From A Knee Replacement Revision
Most patients are able to care for themselves and resume normal daily activities within 6 weeks and drive within 3 to 6 weeks. For some Recovery Time for Knee Replacement Surgery may take 4 to 6 months or up to an entire year to fully recover and realize total benefits of knee replacement surgery.
However, Knee Replacement Recovery Time for the Elderly is more as compared to adults because of the age factor and less exercise done by them as compared to adults.
Prosthetic Pieces Become Loose From The Bone
Partial knee replacements can loosen over time from the bones they are attached to. In other words, the glue or grout that connects the prosthetic knee parts to your bones can weaken or disconnect.
This often creates the classic start-up pain, whereupon rising from a seated position creates moderate to severe pain in the joint. As you walk, gravity and pressure can re-seat them in position and the pain may lessen somewhat.

What Are The Risks
- An infection at the surgical site is possible. Blood clots are a risk as are injuries to a blood vessel or a nerve. These complications are quite rare.
- You may experience some knee joint stiffness.
- Late complications may include infection and a failure or loosening of the prosthesis, as well as continued pain.
What Are The Symptoms Of A Knee Replacement Failure
Certain signs and symptoms, such as increased pain or limited knee function, may indicate that youre experiencing a joint failure. Other symptoms of a failed knee replacement include:
- Pain in the knee
- Instability in the joint
- Redness and warmth
The redness and warmth associated with a joint replacement failure are due to inflammation and can be significant.

Introduction: Total Knee Replacement
Total Knee Replacement is one of the most successful orthopedic procedures of the twentieth century. This is due to the substantial pain relief and restoration of function after TKR. Improvements in surgical materials and techniques have greatly increased its effectiveness approximately 581,000 knee replacements are performed each year in the United States.
With newer implant designs and improved surgical techniques, total knee replacements can be expected to function well for at least 15 to 20 years in more than 85-90% of patients. However, some procedures will fail and require a second surgery, called revision knee replacement.
Your Knee Is Always Swollen
Swelling is another sign your knee is not responding to other treatments.
A knee that is consistently swollen despite the use of anti-inflammatory medications, steroid injections and physical therapy suggests degeneration of the cartilage and/or instability of the knee, which can be confirmed with an X-ray, Lieberman explains. This can make you a candidate for a total knee replacement, he says.

Whats Involved With Revision Hip Replacement Or Revision Knee Replacement
In most cases, revision surgery is more complicated and takes longer to complete than the original total joint replacement, and requires an experienced surgeon and support team. The surgeon must remove the original, failed implantand sometimes surrounding bone and tissuealong with any surgical cement used to hold it in place before he can place the new implant. If the original implant was uncemented, any bone that has grown into it must first be removed.
Because bones may be weaker than they were when the original surgery was performed, they may need to be reinforced with bone grafts or bone particles from your own body or from a bone bank. Metal plates, wedges, rods, or wire may also be necessary. Revisions require a special implant, and in some cases you may even need a custom implant made just for you by the manufacturer. Recovery time is also usually longer for revision surgeries.
What Is The Actual Success Of Knee Replacement Surgery
Knee replacement surgery is a common orthopedic procedure. More than 670,000 knee replacement surgeries are performed annually . Does it work? Credible high-level evidence is essential to understanding the actual success of the surgery. The gold standard in research is a randomized controlled trial study . A randomized controlled trial study is a scientific trial in which subjects are randomly assigned to one of two groups: the experimental group receiving the intervention being tested or the control. The goal is to reduce bias when testing the effectiveness of new treatments. Is there such a study that examined the effectiveness of knee replacement surgery?
Absolutely! The best study to date performed on knee replacement is a 2015 RCT that compared knee replacement to physical therapy. 95 patients with moderate to severe knee Arthritis who were eligible for knee replacement surgery were randomized into the two groups. In the first group, patients underwent knee replacement followed by 12 weeks for physical therapy. In the second group, patients received 12 weeks of physical therapy. This showed some interesting things.

Do I Need Revision Surgery If My Knee Replacement Is Loose
In some cases, according to the Hospital for Specialty Surgery, your doctor may recommend that you undergo revision knee surgery to help resolve issues with a knee implant. During revision surgery, the failed implant is removed and replaced with a new implant.
Revision surgery can be difficult because a failed knee implantcan damage the bone and tissue around a replaced joint. These circumstances may require extensive planning, additional care during surgery, and preventative measures including the grafting of new bone and the use of specialized tools.
Because of the high potential for localized trauma during implant failure and revision surgery, recovery may be difficult on patients bodies. Additionally, these individuals may be at a higher risk for future knee implant failure.
