Patient Age Is A Factor When Considering Partial Knee Replacement
Research clearly tells us that knee replacement is a safe and effective surgery, says Dr. Breien. But knee implants dont last forever. The life of an implant varies with the stress placed on it. When a 60- to 70-year-old patient has a total knee replacement, it will probably never have to be replaced. But when arthritis strikes early, the prognosis changes significantly.
Weight and activity significantly affect implant longevity, observes Dr. Breien. A 30-year-old usually lives a much more active life than a patient over 60 years of age. Thats why a total knee replacement in a 30-year-old might only last 15 years. When the implant wears out, replacing a total knee with another total knee is a major redo. And the outcome for the second total knee replacement is never going to be as successful as the first one. That now-50-year-old still has a lot of life to live. How do we keep that knee functioning in the second half of this patients life?
Avoiding Problems After Surgery
KEEP KNEE STRAIGHT WHEN RESTING – NEVER PLACE A PILLOW UNDER THE BACK OF KNEE – place your foot on an ottoman, chair, or on a rolled up pillow so air is under the knee, push the knee down in extension this is THE MOST IMPORTANT STRETCH OR EXERCISE after knee replacement.
WORK ON THE BEND – slide the foot under the chair, stretch the bend.
Blood Clot Prevention: Follow your orthopaedic surgeon’s instructions carefully to minimize the potential of blood clots which can occur during the first several weeks of your recovery.We are very aggressive in minimizing the risks of clots and have been successful in significantly decreasing the risks of clots.
Warning signs of possible blood clots in your leg include:
- Increasing pain in your calf.
- Tenderness or redness above or below your knee.
- Increasing swelling in your calf, ankle and foot.
Warning signs that a blood clot has traveled to your lung include:
- Sudden increased shortness of breath.
- Sudden onset of chest pain.
- Localized chest pain with coughing.
Notify Dr. Hickman immediately if you develop any of these signs.
Preventing Infection : The most common causes of infection following partial knee replacement surgery are from bacteria that enter the bloodstream during dental procedures, urinary tract infections, or skin infections. These bacteria can lodge around your knee replacement and cause an infection.
Warning signs of a possible knee replacement infection are:
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.

Minimally Invasive Partial Knee Replacement
Unicompartmental knee replacement is a minimally invasive surgery in which only the damaged compartment of the knee is replaced with an implant. It is also called a partial knee replacement. The knee can be divided into three compartments: patellofemoral, the compartment in front of the knee between the knee cap and thigh bone, medial compartment, on the inside portion of the knee, and lateral compartment which is the area on the outside portion of the knee joint.
Traditionally, total knee replacement was commonly indicated for severe osteoarthritis of the knee. In total knee replacement all worn out or damaged surfaces of the knee joint are removed and replaced with new artificial parts. Partial knee replacement is a surgical option if your arthritis is confined to a single compartment of your knee.
What Is The Most Commonly Reported Problem After Knee Replacement Surgery
One of the most common issues after knee replacement is a stiff knee joint. Symptoms of these conditions typically make it difficult for people to perform normal activities such as going down stairs, sitting in a chair, or leaving the car. It can be difficult to manage a stiff knee joint after a knee replacement.
A significant number of knee replacement complications do not occur for a significant period of time. Surgery may result in complications and risks. The procedure for knee replacement is no exception. The general risks of any surgery, as well as the specific risks and long-term problems that may arise from a partial knee replacement, can be found in this section. There are risks associated with surgery, but these are extremely rare. Before your surgery, your doctor will review all of these issues with you. A partial knee replacement is thought to be less painful than a total knee replacement because the surgery is less extensive and there is less preserved knee tissue such as the ligaments.

What Is Unicompartmental Knee Replacement
Unicompartmental knee replacement is a minimally invasive surgery in which only the damaged compartment of the knee is replaced with an implant. It is also called a partial knee replacement.
The knee can be divided into three compartments: patellofemoral, the compartment in front of the knee between the kneecap and thighbone, medial compartment, on the inside portion of the knee, and lateral compartment which is the area on the outside portion of the knee joint.
Five Reasons Why Knee Replacements 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 instead to use biologic fixation, meaning no cement placed between the implant and the bone.
Although implants are firmly fixed at the initial knee replacement surgery, they may become loose over time. The cause of loosening may not always be clear but high impact activities, excessive body weight and wear of the polyethylene component may all act as contributing factors. 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 body’s attempt to digest these wear particles. During this process, normal, healthy 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.
Infection
Revision surgery of the infected knee can take several forms. Depending on the degree of infection and damage, the surgeon will determine one of two basic courses of action:
Instability
Leg fractures
Stiffness

Complications And Risks Of Knee Replacement Surgery
Most patients who choose to have knee replacement surgery are very happy with their . Typical patients find relief of pain, and an ability to increase their activities. However, there are possible complications of the surgery, and why knee replacement patients may not be happy. Here are five problems that can frustrate patients who have knee replacement.
Total Knee Replacement: What To Expect After Surgery
A loosening of the implant can cause pain after knee replacement surgery for years. Over time, wear and tear on implants can cause them to loosen, though obesity and high-impact sports can aggravate the situation. For a few weeks following total knee replacement, you may experience general discomfort. After surgery, a patient may experience swelling for 2 to 3 weeks, but swelling can last for 3 to 6 months or longer. What causes pain behind the knee after total knee replacement? In most cases, these connective tissues are damaged as a result of surgery or by the implant in its place. The cause of a knee wobble is unknown, but it can lead to instability, hypermobility, and even instability. When an individual exhibits this chronic, unsteadiness and hypermobility, they frequently pull and tug at the tendons and ligaments, causing a great deal of pain.

Indications Of Unicompartmental Knee Replacement
Traditionally, total knee replacement was commonly indicated for severe osteoarthritis of the knee. In total knee replacement, all worn out or damaged surfaces of the knee joint are removed and replaced with new artificial parts. Partial knee replacement is a surgical option if your arthritis is confined to a single compartment of your knee.
Wound Irritation Or Breakdown
Surgery will always cut some skin nerves, so you will inevitably have some numbness around the wound. This does not affect the function of your joint. You can also get some aching around the scar. Vitamin E cream and massaging can help reduce this.
Occasionally, you can get reactions to the sutures or a wound breakdown that may require antibiotics or rarely further surgery.

Why Do Knee Replacements Fail And What Are The Symptoms Of Knee
Knee-replacement surgery aims to provide patients with a new knee that will be able to last them at least several decades, and research confirms that the vast majority of knee replacements, even up to 96 percent of all cases, are still functional at the 20 year mark. Knee replacements, though built to be durable, can indeed fail or wear out. What are the circumstances under which happens, what are the signs of knee-replacement failure, and what are your options if you are suffering from one?

The Warning Signs Of A Failed Knee Replacement
A failed knee replacement is not a common problem for the majority of those who have undergone either a total or partial knee replacement. Around 95 percent of those receiving a knee joint replacement see no issues for the planned lifespan of the joints of between 15 and 20 years. There is a range of symptoms seen with a knee replacement joint failure which can be due to an improperly designed piece of hardware or the general wear and tear of living a normal life. Recent news has come to light of the Attune knee failure which is now being recalled and replaced with a redesigned artificial knee.
Symptoms of a failed knee replacement
There are a number of warning signs any person who has undergone knee replacement surgery should be aware of, including a large amount of soreness or swelling in the affected joint. A condition is known as Crystalline arthropathy is a concern for many physicians and surgeons as they seek the best ways of identifying a failing joint. This common problem sees the knee joint feel as though an infection is taking hold but is, in fact, the result of the crystallization of the failing hardware.

Younger Patients Benefit From Partial Knee Replacements
Younger patients with arthritic knees are the best candidates for a partial knee replacement, states Dr. Breien. We generally use a partial knee replacement to preserve knee function for patients between the ages of 30 and 60. Then we can convert to a total knee replacement. With this care strategy, patients can look forward to continued function for the remainder of their lives.

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.
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.

For these reasons, Dr. Breien takes a very strategic long-term approach to treating younger patients with advanced arthritis. A total knee is not an ideal solution for a young patient, he explains. If only a portion of the joint is damaged by arthritis, a partial knee replacement can be an excellent option.

What happens after I schedule surgery?
Dr. Hickman’s medical assistant will schedule your surgery with the facility you and Dr. Hickman have selected. The M.A. will then authorize this procedure with your health insurance company. Please understand that authorization is not a guarantee of payment and it is always a good idea to check with your insurance company also regarding deductibles, copays, and coinsurance responsibilities. You also should have selected a preoperative appointment in our office. This usually takes place 1-2 weeks prior to your surgery date.
How do I prepare for surgery?
Have nothing to eat or drink after midnight the night before your surgery. You should also wash your surgical site with an antibiotic soap . You do not need to shave over your surgical site, this will be taken care of in the operating room.
What time will my surgery be?
Your surgery time will be set by the hospital or surgical center. They will contact you on the last working day before the surgery. They usually call after 1 pm. Questions or concerns regarding the time of your surgery should be addressed to the hospital.

Advantages Of A Partial Knee Replacement
The nice part about a partial knee procedure is that your knee will feel more normal following surgery, says Dr. Breien. With a partial knee replacement of a kneecap, for example, we leave the ACL and the PCL ligaments intact. Those ligaments send tension and flexion messages to the brain. After surgery, those ligaments in the knee are still speaking to the brain. Postsurgical patients report that their knee feels the same, minus the pain.
Total knee replacements, on the other hand, take some getting used to. After a total knee, the implant doesnt talk to your brain as your old knee used to, observes Dr. Breien. And the younger you are, the less youll probably love how a total knee replacement feels. My 70- and 80-year-old total knee replacement patients are just thrilled to walk without pain. The satisfaction of patients in the 60-year-old category will depend on individual activity levels. An active 50-year-old will be happy that their knee doesnt hurt anymore, but its a challenge to become accustomed to the way the implant feels. The younger you are, the more difficult it is to adapt to the sensation of a total knee replacement.
How To Avoid A Loose Knee Replacement
Dont have the knee replacement surgery. Dig deep, understand the problem/problems with your knees, and evaluate all nonsurgical treatment options. Realize that once the joint is amputated there is no turning back. If you are dissatisfied with your results you cant ask for your knee back. The mechanics of the knee joint are changed forever after knee replacement surgery.

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%.
