Joint Replacement Surgery 

Robotic-assisted knee and hip implant surgery at DCH Joint Replacement Program offers a multitude of advantages for patients. Because it is so precise, this surgery allows for more accurate implant positioning. This can result in a more natural feeling after surgery. Additionally, this type of surgery offers improved safety and a reduced risk of injury to adjacent tissues. Robotic-assisted surgery also involves small incisions – which can mean a quicker recovery, a shorter hospitalization, and less pain. 

All these factors combined increase the potential for a better outcome, and better long-term function, allowing patients to get back to their lives more quickly and with greater mobility. 

How Robotic-Assisted Total Knee and Hip Replacement Works

Mako Robotic-Arm Assisted Technology, available at Northport Medical Center, provides you with a personalized surgical plan based on your unique anatomy. First, a CT scan of the diseased joint is taken. This CT scan is uploaded into the Mako System software, where a 3D model of your knee is created. This 3D model is used to pre-plan and assist your surgeon in performing your partial knee replacement. 

In the operating room, your surgeon follows your personalized surgical plan while preparing the bone for the implant. The surgeon guides the robotic arm within the pre-defined area and the Mako System. The surgeon guides the robotic arm within the pre-defined area and the Mako System helps the surgeon stay within the planned boundaries that were defined when the personalized pre-operative plan was created. 



• A Precise Fit

Robotic hip and knee replacements is one of the recent advances in medical technology that is making replacement surgery easier and more successful than ever before. Our surgeons can now customize joint replacement surgery to closely match the unique anatomy of each patient. This results in a precisely fitting, long-lasting, and well-functioning hip implant. 


• Precise Implant Placement

During the surgery, the surgeon guides the robotic arm to the location of placement of the hip implant with the help of interactive data which is updated in real time. With the robotic arm the surgeon can achieve highly precise implant positioning and make adjustments during the procedure for exact alignment. 


• Reduced Failure Rate

Although the risk is minimal, hip and knee replacements can fail for several reasons, including dislocation, infection, loosening, and mechanical problems with the implant itself. When performed in the traditional way – without robotic assistance – hip and knee implants are most prone to loosening. 

Using CT-derived simulation, the surgeon can position the implant in a way that allows for natural movement patterns. Doing so helps minimize the stress on the knee or hip, resulting in less friction and wear and tear of the implant. In addition to helping alleviate loosening issues, problems such as implant breakdown or leg length discrepancy are less likely to occur with robotic knee or hip replacement. 

• Tissue Sparing

Robotic-assisted knee and hip replacement allows the surgeon to preserve as much of the healthy bone tissue as possible while only removing damaged or necrotic tissue. 


​• Faster Recovery

Patients who undergo robotic-assisted knee and hip replacement are often up and about within a day or two after surgery. Yes, complete rehabilitation may take a couple of months, but overall, robotic surgery allows for a quicker, less painful recovery. 

If conservative treatments have failed, robotic knee or hip replacement could be the answer. Advanced technology, in the capable hands of highly-skilled surgeons, allows for more successful outcomes for patients, with fewer post-surgical complications, more precise implant placement, reduced damage to surrounding tissues, and a faster, less painful recovery.
