Knee Replacement Surgery in New York

Introduced in 1968, knee replacement surgery has advanced significantly during the past nearly five decades.

Since then, there have been advancements in technology, materials and surgical techniques to offer millions of men and women greater mobility and improved range of motion.

With that being said, using the latest techniques, Dr. Karkare only performs  the latest minimally invasive knee replacement surgeries.

With multiple offices throughout Long Island and two locations in New York City, I’ve helped hundreds of people just like you lead productive, fulfilling, pain free lives with a functional knee.

What is Total Knee Replacement Surgery?

Total knee replacement replaces a joint that’s become damaged by the effects of arthritis, which causes the cartilage on joint surfaces to slowly wear away, revealing the unprotected ends of the bones underneath.

Without this protective cartilage barrier, even the slightest movement can be painful, and everyday activities like walking, climbing stairs and even standing up can be excruciating.

Furthermore, severe arthritis can result in decreased mobility which takes a huge toll on your quality of life and limits the amount and types of activities you can perform.

This is why knee replacement surgery is a solution for many patients, it helps people live a more active life because it replaces those damaged joints making normal human movements more comfortable again.

Given that a knee replacement is a major surgery, it is performed as a last resort when other, more conservative options like medication, injections, and physical therapy have failed to provide relief or aren’t an option.

What is Custom Knee Replacement?

Custom knee replacements use MRI scans and x-rays to obtain precise measurements of your knee which can guide the surgeon during the knee replacement procedure.

Then, data from the MRI and x-ray are fed into a computer, which uses special software to determine where the bone should be incised, or cut, in order to preserve as much healthy bone and ligament tissue as possible.

This type of knee replacement offers patients some substantial benefits over standard surgical techniques, including:

  • precise fit and alignment of the new joint
  • faster recovery
  • less blood loss
  • decreased risk of infection
  • less postoperative pain and discomfort
  • faster return to normal activities

How long does knee replacement surgery take?

To facilitate movement, a metal joint is attached to the ends of the upper and lower leg bones and a special spacer is inserted. In some cases, the kneecap, or patella, will be resurfaced as well. It takes about 1-2 hours to perform total knee replacement surgery under general anesthesia.

What is Revision Knee Replacement?

Revision knee replacement is for those who have already had one knee replacement, and a revision is needed. This can be anything from a minor adjustment, to an involved procedure replacing a large amount of your bone. Read more about revision knee replacement here.

How does Conformis knee replacement technology work?

The Conformis process starts with a patient CT scan through the hip, affected knee, and ankle. iFit® software converts the 2-dimensional CT data into a 3-dimensional model that replicates that patient’s unique and anatomical bone geometry.

In the 3D environment, iFit® recreates the patient’s natural J curves, corrected for deformity. It builds the femoral and tibial implants to match the unique size and shape of each knee. Further, it addresses common causes of patient dissatisfaction, pain, and unnatural feel.

Conformis has pioneered additive manufacturing and 3D printing technology for producing single-use, patient-specific. A patient uses positioning guide that comes pre-sterilized instead of reusable instruments that require cleaning and re-sterilization.

IFit® design and manufacturing technology enables mass-customization, a term foreign to the orthopedic industry. It customizes implants and instruments are delivered pre-sterilized unlike any knee replacement available today.

Simply put, iFit® technology put Conformis in a class of its own with an unparalleled speed of innovation, and our source for Conformis is Empire Surgical Solutions, right here in New York.

Are you a good candidate for TKR surgery?

Total knee replacements can be a good option for many men and women, but they’re not for everyone. If you have been experiencing knee pain, have had a prior knee surgery, or have injured ligaments, you may need a complete knee replacement.
