About joint replacement at Northwell Health

Our surgeons bring the most advanced orthopaedic procedures, backed by Northwell Health’s own extensive research studies, to the operating room every day. Dedicated to ongoing innovation, our orthopaedic research scientists and practitioners are constantly offering hope for patients with chronic hip and knee pain.

Our joint replacement surgeons are experts in minimally invasive techniques, which use specialized surgical instruments through small incisions. In some  cases, our specialists can perform surgery via a robotic surgical system that allows them to operate more precisely. The benefits of these innovations include:

  • Less trauma to soft tissue
  • Reduced pain and blood loss
  • Quicker recovery
  • Fewer complications, such as infection
  • Smaller scars

We use the most advanced robotic technologies, including:

  • Mako Robotic Arm – A surgeon-interactive robotic arm that enables highly accurate hip and knee implant placement.
  • Navio Robot-Assisted Surgical System – An image-guided system with handheld instrumentation to help surgeons deliver robotic precision during partial knee replacement surgery.

Hip replacement

If you’re struggling with hip pain caused by osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, fracture, torn labrum or other conditions of the hip joint, you’re not alone. More than 285,000 people undergo total hip replacement each year.

Our highly trained joint replacement surgeons perform advanced surgical hip replacement surgery procedures using the latest medical breakthroughs, including:

  • Total hip arthroplasty – A surgical treatment to replace damaged sections of the hip joint. During the procedure, the damaged joint is removed and replaced with a prosthetic socket implanted into your pelvic bone and a prosthetic ball attached to a stem that fits into your thighbone. Total hip arthroplasty is recommended for treating arthritic hip pain and loss of function when medicines and other treatments are not effective.
  • Posterior approach to hip replacement surgery – Traditional hip surgery uses a posterior approach, with the orthopaedic surgeon making an incision close to the buttocks to access the hip joint. Primary leg muscles used for walking are bypassed. This approach has a long record of success and a low complication rate. Recovery time following surgery varies, depending on the patient’s age, activity level, weight and other factors.
  • Anterior approach to hip replacement surgery – An anterior approach means that the surgeon reaches the hip by going between two muscles, rather than by detaching and then reattaching a muscle. The advantages of this innovative, muscle-sparing approach to hip surgery are faster healing and improved mobility. The incision is in the front which eliminates pain from sitting on the incision site. Keeping the muscles intact can also reduce the risk of dislocations.
  • Hip revision surgery - Prosthetic joints used in hip replacement surgery have a finite lifespan. The typical life of an artificial hip joint is approximately 10 to 15 years, depending on the daily use of the joint. When that time comes, revision surgery replaces worn-out components. The joint replacement surgeons at Northwell Health are well-trained in revision surgery and skilled in this complex procedure.

Knee replacement

When stiff, painful knees don’t respond to conservative treatments such as physical therapy and medication, surgery may be an option. At Northwell Health, we can relieve your pain and restore your active lifestyle through a variety of surgical options with proven success, which include:    

  • Partial knee replacement surgery – In some patients, arthritis is limited to just one part of the knee. When this is the case, partial knee replacement may be an option. Also known as uni-compartmental knee replacement, this surgical treatment replaces the damaged knee compartment with an implant, while the healthy cartilage and bone in the rest of the knee is retained. The benefits of partial knee replacement include a smaller incision, less blood loss, faster recovery time, and quicker return to normal activities.
  • Total knee replacement – During total knee replacement, the knee joint is resurfaced by removing the diseased bone and cartilage. These surfaces are replaced with a metal and plastic implant that can help alleviate the pain of arthritis while increasing mobility and function. Because there are subtle differences in the anatomy of men and women, knee implants are designed specifically to accommodate for the different size of the bones between genders. This increases functionality and durability of the implant.
  • Custom fit knee replacement – This new approach to knee replacement uses custom-fit knee implants that are created using advanced 3-D imaging to capture the true anatomy of the patient’s knee. The benefits of custom-fit knee replacement include a more optimal fit of the implant.
  • Knee revision surgery – Over time, a knee implant can begin to fail because of normal wear and tear. With decreased joint functionality and increasing pain symptoms, knee revision surgery may be necessary. During this surgery, the damaged components of the existing implant are removed and a new prosthesis is inserted. The joint replacement surgeons at Northwell Health are well trained in revision surgery and skilled in this complex procedure.
  • Robotic partial knee replacement – Although total knee replacement is the most common knee replacement surgery, robotic partial knee replacement, using either the Mako robot or the Navio robot-assisted surgical system, is an option for some patients. This minimally invasive procedure is performed through a limited incision using a robotic guidance system to remove and resurface only the arthritic part of the knee while preserving healthy portions of the knee joint.
