Ial Knee Replacement Surgery Results In Better Outcomes And Is Cost
Dr. Hassan Ghomrawi
Partial knee replacements are economically superior to total knee replacements in older adults, and with a few small improvements, can be an attractive option for younger patients as well, new research from Weill Cornell Medical College and Hospital for Special Surgery investigators suggests.
Knee replacement surgeries are expected to surpass one million annually by 2020, with half of these surgeries being performed on patients younger than 65. Historically, physicians have recommended total knee replacements for all adult patients including those who have end-stage osteoarthritis in part of the knee joint. But in their study, published March 4 in the Journal of Bone and Joint Surgery, the Weill Cornell investigators found that partial knee also known as unicompartmental replacements provide greater economic value to patients over the age of 65 compared to total knee replacement, as they are less likely to face surgical complications and require less physical therapy than those who undergo total knee replacement surgery.
“With a unicompartmental knee replacement, you’re more likely to return to work earlier and have better function compared to total knee replacement, which requires more rehabilitation and has more complications,” said lead author Dr. Hassan Ghomrawi, an assistant professor of healthcare policy and research at Weill Cornell and a research scientist at Hospital for Special Surgery.
Ial Vs Total Knee Replacement
Knee replacement surgeries are safe and effectively manage the pain and disability caused by osteoarthritis. During knee replacement surgery, the ends of the diseased joint are replaced with prosthetic metal and plastic parts.
While in total knee replacement all the compartments of the knee joint are usually replaced, a partial knee replacement only involves the replacement of a single knee compartment.
The knee joint is divided into three compartments or spaces. The joint is formed by the lower end of the thigh bone, the upper part of the shinbone, and the undersurface of the kneecap.
The inner side of the knee is called the medial compartment, and similarly, the outer side of the knee forms the lateral compartment. In front of the knee, the joint formed by the kneecap and the thigh bone forms the patellofemoral compartment.

The bones forming the knee joint are covered with a glistening white tough tissue known as articular cartilage. The articular cartilage helps in the smooth gliding of the joint in motion. Various ligaments, meniscus, and muscles provide additional stability to the knee joint.
Patients with knee arthritis may complain of pain, stiffness, or deformity. A knee replacement surgery is only offered to the patients when all other nonsurgical treatments have been tried. Nonsurgical treatments include physical therapy, cortisone injections, and pain medications, etc.
Candidates For Partial Knee Replacement
In 1998, two doctors established criteria for determining which patients were good candidates for partial knee replacement. The ideal patient has these characteristics:
- Older than 60 years old
- Less than 180 lbs
- Has good range of motion before surgery
- Has minimal deformity
Patients with inflammatory types of arthritis, such as rheumatoid arthritis, are not regarded as good candidates for partial knee replacement. With inflammatory arthritis, more than one compartment is usually involved.

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.
Should You Consider Unicompartmental Joint Replacement Surgery
Over 790,000 knee replacement surgeries occur in the US every year. Unicompartmental knee surgery should be considered since the treatment replaces only part of the knee. The surgery happens when the pain is limited to part of the knee and is especially helpful for patients with osteoarthritis. In cases of stiffness and ligament damage, surgery may also be recommended. Unicompartmental knee replacements have great results in both young and older patients.

Advantages Of Partial Replacements
Right at the top of the list is a smaller incision. Since this method removes less bone tissue and cartilage AND its contained to one area, your surgeon will only need about half the incision area compared to total replacement. Less trauma both internally and externally equates to a much faster recovery.
Speaking of recovery, that tends to be slashed in half as well . Total knee replacement usually requires you stay in the hospital about 5 days and therapy takes another 4-6 weeks before you start feeling stable and relatively pain-free. With partial replacement, most patients are discharged 1-2 days after surgery, some even the same day. After about 2-3 weeks of therapy, most patients have healed up quite well and can resume most of their daily activities.
Finally, with less cutting and trauma to the actual knee, there are much fewer complications associated with partial. In general, theres a much smaller risk of infection and bleeding is kept to a minimum.
More Normal Motion With Oxford Knee Implant
The Oxford® Unicompartmental Partial Knee Replacement prosthesis allows for a better range of motion of the knee by virtue of replication of the function of the menisci and allows for more normal motion of the human knee. With the Oxford partial knee replacement, only a portion of the knee is replaced.
In performing an Oxford, the anterior cruciate and posterior cruciate ligaments are always preserved. In performing a total knee replacement, the anterior cruciate ligament is always removed sometimes the posterior cruciate ligament is removed as well.
In some cases, this prosthesis may be applicable to individuals who were previously considered too young to undergo a total knee replacement.
The Oxford knee implant utilizes a minimally invasive procedure in which patients may experience less pain and a quicker recovery time than experienced with a total knee replacement. Read about the Oxford partial knee replacement recovery time.

Benefits And Risks With Partial Knee Replacement
There are benefits to having a partial knee replacement as compared to a total knee replacement. The same complications are possible with both surgical procedures: loosening, infection, nerve injury, fracture of the bone and more.
-
A higher revision rate for partial knee replacement than total knee replacement
-
Potentially worse function after revision of partial knee replacement than total knee replacement
-
Revisions can be more complicated than primary surgeries
What Is The Recovery Time For Partial Knee Replacement
Most patients can expect to be back to their daily activities within three to six weeks. Many patients find that after undergoing physical rehabilitation, they are able to return to sports such as golf within 6 to 10 weeks. Patients can usually expect to go home the same day of surgery, unless they have a medical condition that requires an overnight stay. At HSS, most patients are also able to walk with assistance, or independently, on the same day as their surgery. Typically, the patient is given a cane within days of surgery to allow for increased independence and begins outpatient rehabilitation. Patients are often finished taking prescription pain medication within one to two weeks after surgery.

Why Come To Houston For An Oxford Partial Knee Replacement
To be qualified to implant an Oxford, the United States Food and Drug Administration requires an orthopedic surgeon to attend a special training course. This training is required because the implantation technique for this procedure is very precise and the operation must be done correctly.
Dr. Likover attended one of the first training courses. As of January 2012, Dr. Likover has implanted over 1100 Oxfords, which means he has more experience in this procedure than most surgeons in the United States. You should consider coming to Houston to have Dr. Likover do your surgery for this reason.
Several people have inquired about Makoplasty robot procedure. The Mako procedure has no long term success rate reported in the orthopedic literature.
The Mako involves placing a fixed bearing implant, which is similar to the Ripici knee implant, with computer guidance and a robot arm. The Ripici implant had a high failure rate. It has not been proven that placing this type of implant by robot technique improves the success rate.
If you have substantial pain in your knee, you should schedule an appointment with Dr. Likover for a complete evaluation of your knee pain problem.
You may only require arthroscopic surgery, you may need an Oxford partial knee replacement, or you may need a total replacement. Most substantial knee pain problems can be helped or cured by modern orthopedic surgery.
Total Vs Partial Knee Replacement Surgery
A knee replacement is a procedure done to replace damage in the knee, often due to arthritis or a severe injury. The most common cause for patients needing a knee replacement is osteoarthritis.
How is a knee replacement accomplished? Surgeons use metal and plastic parts to cap the ends of the bones in the knee joints and the kneecap.
The goal of the surgery is to repair damage in the knee, so the patient finds relief from pain and better mobility in the joint.
There are two types of knee replacement surgery: a partial knee replacement and a total knee replacement. Your physician will work with you to determine which procedure is appropriate based on your condition.

Is A Smaller Surgery Always Better
Most people know what a total knee replacement is. But what about a partial knee replacement? While the thought of having a smaller surgery may be immediately appealing, partial, or unicompartmental, knee replacement isnt the right choice for every patient. Both total and partial joint surgeries have different benefits for different patients.

Ial Vs Total Knee Replacement: Choosing The Right Option
Arthritis or severe injury to the knee eventually can cause the joint to break down, making it painful, swollen and stiff. When the pain begins to interfere with your daily life, you may need to consider joint replacement surgery. The first decision you and your doctor will need to make is choosing between partial vs. total knee replacement. Heres an overview of the key factors to consider.
Ial Knee Replacement Surgery
Partial knee replacement surgery or unicompartmental knee arthroplasty offers an alternative to patients with damaged knees if the damage is confined to a particular compartment of the knee.
Earlier, this procedure was generally performed on older patients as they were unlikely to overexert themselves. Today, partial knee replacement has risen in popularity even in the younger population as it has a lower recovery time as well as decreased post op pain.
However, this surgical alternative is not suitable for everyone. It is estimated that about 5%-6% of patients with arthritis of the knee are eligible for partial knee replacement surgery.
This procedure can be performed on patients having medial or lateral knee osteoarthritis. Medial is the inside compartment of the knee, closest to the opposite knee, while lateral refers to the outward compartment which is farthest from the opposite knee.
In order to determine if the patient is a suitable candidate for partial knee replacement surgery, the surgeon will:

What Is Partial Knee Replacement Surgery
Partial knee replacement is where the bone surfaces of only one compartment of the knee joint are removed and replaced with implants, as compared to that of multiple compartments in the case of a total knee replacement. It is a common treatment for unicompartmental arthritis.
Patients with unicompartmental knee arthritis have cartilage degeneration in only one section or compartment of the knee. In cases where nonsurgical techniques do not provide symptom relief, surgeons can remove damaged cartilage and bone in the diseased area only, while preserving the ligaments that help support the knee joint, explains , Attending Orthopedic Surgeon at HSS.
An implant which may also be called a prosthesis takes the place of the damaged area of the knee, leaving the other compartments intact. Improvements in surgical techniques and instrumentation have made partial knee replacement an increasingly viable option for a growing number of patients. In fact, recent data suggests that anywhere from 10% to 25% of all patients with osteoarthritis of the knee needing replacement surgery may be eligible for the procedure. “” rel=”nofollow”> Find a surgeon at HSS who performs partial knee replacement.)
Its All About Location
Unicompartmental knee surgery often depends on the location of the pain. If the pain is on the inside or the outside of the knee, then the doctor may recommend unicompartmental joint replacement. If the pain is in the entire knee or the front knee, a total replacement may be best. After a full recovery, most patients report reduced pain, improved range of motion, and high satisfaction.

Whats The Difference Between A Partial And Total Knee Replacement
Joint replacement surgery can either be a partial or total replacement, and both types can be done using minimally invasive methods. The type of knee replacement surgery your orthopedic surgeon recommends will depend on your age, general health, and specific joint damage.
Medically speaking, the knee consists of three areas:
- Medial
- Lateral
- Patellofemoral/anterior
A partial knee replacement involves replacing one or two of these components, while a total knee replacement replaces all three.
If I Have Partial Knee Replacement Does That Mean That I Will No Longer Have Arthritis Of The Knee
Partial knee replacement will address the arthritis that is present in the particular compartment of the knee that is already affected. In addition, the knee is typically rebalanced by the procedure, which improves its stability. While rare, there is no guarantee that arthritis will not progress elsewhere in the knee. Should this occur, a surgical revision to a may be necessary.

Benefits Of Partial Surgery
Patients who are good candidates for a partial knee replacement may experience a faster recovery and less pain. Because some of the natural bone and ligaments are still in place, the patients knee may bend better after a partial knee replacement. Some patients also just appreciate knowing that not the entire knee is prosthetic.
Ial Versus Total Knee Replacement
Knee replacement is a common procedure for people suffering from osteoarthritis and other pain knee conditions. This surgical procedure involves the removal of all or part of the knee joint and replacement of damaged parts with an artificial plastic or metal joint. While recovery could take several months, knee replacement provides long-term or even lifetime relief from pain.
A partial knee replacement surgery only involves the replacement of the affected knee compartment, preserving the anterior and posterior cruciate ligaments. Factors that make you an ideal candidate for partial knee replacement include:
- Minimal knee deformity
- Weighing less than 180 lbs.
- Sedentary lifestyle
- A good range of motion prior to the surgery
While partial knee replacement may seem like a less complex option, it is crucial to be aware of the differences between a partial and a total knee replacement surgery. As a candidate for knee replacement surgery, you should understand that each surgical procedure is unique and has its own set of benefits and risks after the surgery.
As its name implies, total knee replacement surgery involves the removal of the entire joint and replacing it with an artificial knee component. It is a safe and effective solution for treating the pain and stiffness caused by knee osteoarthritis.

Ial Vs Total Knee Replacement: What Is The Difference
According to the American Academy of Orthopedic Surgeons, nearly half of all American adults develop knee osteoarthritis in at least one knee during their lifetime. Additionally, the demand for total knee replacement surgery is expected to exceed 3 million by the year 2030. However, its important that sufferers of knee conditions examine their options before committing to a full-fledged surgery. Both partial and total knee replacement can offer many benefits and a better quality of life depending on your specific needs and health issues.
We rely on the knees for a lot from occupations that require us to stand for long periods, to the weekend warriors who have amassed many medals from marathons. And, while the knee is equipped for action, it isnt immune to impairment. Most patients who undergo partial knee replacement, or unicompartmental knee arthroplasty, do so after developing osteoarthritis of the knee. Cartilage is the important rubbery, connective tissue in the body that prevents friction as this tissue inevitably wears down, the lack of protection between bones can result in bone spurs and persistent pain. The degenerative, wear-and-tear that defines osteoarthritis is caused by years of overuse and frequently develops in those over the age of 50.
