Partial Knee Replacement

Avoid Total Knee Replacement.
The Amazing Partial Knee Option!

Minimally Invasive Selective Knee Resurfacing — the Superior Option to Total Knee Replacements

Imagine a return to the highest level of activity without sacrificing your knee joint! Selective resurfacing of ONLY the arthritic part of your knee can accomplish this. This proven procedure, currently in its second decade of success, allows you to keep your important knee ligaments, keep the healthy parts of your knee, and bring you to activity not imagined in total knee replacements. You get MORE NATURAL MOTION and LONG-TERM DURABILITY.

Significant Experience in Performing Knee Resurfacing

Dr. Kirschenbaum is one of the national proponents and leaders in knee resurfacing. After being evaluated in consultation at his Joint Replacement Center the surgery is performed at The Westchester Orthopaedic Institute within the hospital ranked #1 in consumer satisfaction by The National Research Council (image of the Award). The Joint Replacement Center performs a high volume of Joint Replacements. Where this operation takes less experienced surgeon hours to perform, The Kirschenbaum Joint Teams routinely performs knee resurface to exacting technical specifications and detail in less than 45 minutes. Blood loss is minimal and recovery is rapid.

What is Partial Knee Replacements and Selective Knee Resurfacing?

Partial knee replacements have been designed for the growing number of patients who want the potential benefits of minimally invasive resurfacing approach to their knee pain. FINALLY- the real alternatives to total knee replacements. The long-term results have been documented and published.(1) Historically, Selective Knee Resurfacing has been referred to by a number of different terms. You may have heard the terms Partial Knee Replacement or maybe even Unicompartmental Knee Replacement, or even Uni Knee. All these refer to Selective Knee Resurfacing. Why is the term Selective Knee Resurfacing a better description of this remarkable operation? The reason is that in this procedure your knee joint is not actually replaced at all. Unlike a total knee replacement where the entire knee joint is fully exposed and removed with large amounts of bone and all the ligament supports, knee resurfacing only removes the surface of the diseased arthritic, bone-on-bone part of the joint and the surgeon literally caps this surface with the highest quality metal and ultra high density polyethylene components.

The Knee Has Three Separate Surfaces - Solutions for Any and All Parts to Avoid Total Knee!

Since the knee has three separate sections, there is an opportunity to SELECTIVELY replace only the diseased section. This can be the space between the femur and the tibia, between the patella and the femur and both small sections of the joint. Dr. Kirschenbaum regularly performs four separate types of knee procedures that are perfectly matched to your needs.

These include the following:

Partial Knee Replacement between the thigh and leg bone (femur and tibia). This is the classic partial knee replacement and the most common.

Partial Knee Replacement of the kneecap (patella). This is for arthritis that is isolated to the undersurface of the kneecap.

Partial Knee of Two or Three Parts of the Knee. This unique option is called the Deuce and allows for replacement of just the small area between the two leg bones AND the knee cap.

  1. A knee designed for a woman’s anatomy and one for a man’s anatomy
  2. The Custom Fit Knee from Otis Med and Stryker
  3. The Super Flex Knee for extra motion

How is the Surgery Actually Performed?

Unlike the traditional total knee replacement, knee resurfacing is the only true minimally invasive knee operation to remove arthritis. Performed through a 3 inch incision in an ultra-sterile operating room environment, only the diseased portion of the knee is exposed. Using a combination of highly-engineered guides and navigation tools, the arthritis at the end of the thigh bone (femur) and the top of the leg bone (tibia) is removed with great care to retain the rest of the knee and all the ligaments. The combination super metal alloy replacement and polyethylene resurfacing components are bonded permanently in place. The minimal incision is then closed.

Why is the Recovery So Much Less Painful and More Rapid Than Total Knee Replacement?

The first has to do with the highly targeted and selective nature of the operation. So much less normal skin, supporting structures, and bone is operated on the pain is restricted to the small area of resurfacing. Additionally, Dr. Kirschenbaum's delicate tissue management in the operating room adds to the minimal trauma to the knee as a whole.

How Fast Can I Recover?

While recovery from surgery is always a personal journey, you can expect recovery from Selective Knee Resurfacing to be as much as six times faster than total knee replacements. Patients in our practice have walked into the office without even the use of a cane in as short as ten days! Most patients can reach this goal in as little as 3 weeks. Your individual recovery may be less or more than this, of course.

Why Do Your Knee Resurfacing Patients Tell Me That the Resurfaced Knee Feels Very Much Like Their Knee Did Before They Even Had Arthritis?

They say this because it often happens that way. In total knee replacements, removing that much bone and ligaments can make your knee lose its sense of being part of your body. Not having your own ligaments anymore prevents you from moving and adjusting to the many demands that you may place on your knee. Selective Knee Resurfacing keeps those ligaments and so much of your own bone. The only thing missing now is the painful bone-on-bone arthritis and who needs that? Patients, in major study after major study, describe Selective Knee Resurfacing at a superior level of satisfaction over any total knee replacement.

How Long Does Selective Knee Resurfacing Last?

Anytime metal implants are used to replace your normal anatomy one has to expect that at some point, parts may wear out. What is unique about Selective Knee Resurfacing is that the results of its life span are identical to total knee replacements. This ranges from 8-16 years depending on many factors. What is so advantageous about Selective Knee Resurfacing is that after its usefulness, you may have many options still available to you when a second operation needs to be done. Total knee replacement burns all bridges to future advances and options. By maintaining the rest of the knee and the ligaments and supporting structures, you may be a candidate for another Selective Knee Resurfacing. Additionally, there is much research on natural biologic knee resurfacing and cartilage replacements. While these advances are not currently available, there is the likelihood that a person who underwent Selective Knee Resurfacing will be a candidate for this procedure when it is available. Future research will shed more light on this opportunity.
