Kayal Robotic Joint Replacement Center Leads the Way in DAA, Robotic-Assisted Surgeries

Updated: Mar 22, 2020



Northern New Jerseyans in need of total hip replacement surgery have a powerful choice available close to home: an innovative method offered at the Kayal Robotic Joint Replacement Center. My esteemed colleague, Dr. Victor Ortiz, chief of hip services, and I are able to combine the direct anterior approach (DAA) to total hip replacement surgery with the Mako robotic surgical arm. DAA is a minimally invasive technique that speeds rehabilitation. During the procedure, trauma to your muscles is reduced because the muscles and tendons are not detached. Add to that the beauty of robotic surgery, which allows us to align and position your new hip more precisely.There are many advantages to minimally invasive surgery, including shorter hospital stays (often outpatient), smaller incisions, less pain, quicker recuperation, minimal scarring, greater return of function and, in some cases, decreased risk of hip dislocation.


Dr.Ortiz and I both have completed special training to use the Mako robotic surgical arm. This state-of-the- art technology is used at the Kayal Robotic Joint Replacement Center to perform hip replacement as well as total knee, partial knee and patellofemoral replacement surgeries.Why Mako? Mako robotic surgery allows us to do a virtual replacement before the surgery so that we can properly position the hip or knee on a cross-sectional image such as an MRI or CAT scan. Using this technology, we can see an exact replica of your unique, bony anatomy in three dimensions. Before surgery, we look at the bone and spin it around in all directions to make sure the implant will fit precisely. The process is similar to constructing a building, which is designed on a computer first to make sure every detail is perfect.Believe it or not in 2019, most orthopaedic surgeons around the country are still doing joint replacement surgery in a traditional manner without employing the use of robotic arm assistance.

It’s not just about making the cuts. Using the software, we can also read the soft tissue to make sure the soft tissue balance and, therefore, the tension on the ligaments is the same throughout the entire arc of motion. It’s here where the robotic-assisted arm makes a remarkable difference. The robot does not allow us to deviate at all from the pre-operative design. In fact, if our hand moves—even a millimeter or two—away from the design, the robot will shut off, not allowing us to make the cuts. So, it results in less-invasive surgery. The technology is unbelievable.
