5 Benefits Of Robotic Surgery

Technology has made some great advances in regards to joint replacement surgery in the last 20 years, and the assistance of robotics in surgery is one of the most significant. Several studies have shown that the robotic surgery when compared to traditional surgical measures have added benefits towards a successful joint replacement. 

Better Accuracy in Implant Positioning

If the prosthesis is not aligned accurately it can cause premature wear and early mechanical detachment which leads to lower success rates in joint replacement. Studies have shown that robot-assisted surgery can provide a more accurate placing of the femoral rotational alignment than conventional surgery, even with less experienced surgeons using the technique.

Decreased Postoperative Pain

Studies have shown that patients who have undergone robotic-assisted surgery for a total knee replacement have reported lower levels of postoperative pain than patients with conventional surgeries.  Less post-op pain avoids the use of narcotics for longer periods of time after surgery and patients may be less likely to have narcotic related side effects such as hypotension and constipation. 

Earlier Functional Rehabilitation

With less postoperative pain after a robotic-assisted surgery patients are able to begin more effective exercises to regain strength and mobility. One study found that patients who had a total knee replacement through robotic surgery had greater improvements in walking and standing after 4-6 weeks than patients undergoing the conventional methods of surgery. Patients have also been reported to be able to perform a straight leg raise earlier in treatment and have a great amount of knee flexion at discharge from the hospital.

Reduced Bone and Soft Tissue Injury

Robotic surgery in joint replacements has shown to cause less damage to the bone and tissue during surgery. This method was shown to be more precise and less invasive to the bone and tissue that other methods of surgery. Less damage to the surrounding tissues leads to less inflammation and swelling in the area and allows a faster and less painful recovery.

Shorter Hospital Stays

The above benefits combined may lead to shorter hospital stays for total joint replacement patients. In comparison to conventional surgical methods, one study found its participants who had the robotic surgery had a median 77 hour hospital stay as opposed to other patients with a median hospital stay of 105 hours.4  The less time a total joint replacement patient is required to stay in the hospital after surgery can reduce the risk for hospital induced infections and decrease the overall cost of the hospital stay and inpatient treatments.
