Robotic-assisted total knee replacements a first for Africa

A total knee replacement operation has been carried out using the state-of-the-art Mako robotic arm-assisted surgery system for the first time in Africa.

This system has been highly praised by professionals and medical specialist defined this as a milestone for the medical profession. The surgery was performed at Netcare Linksfield Hospital in Linksfield, Johannesburg.

Orthopaedic surgeon, Dr Chris McCready, who practices at the hospital and performed this African surgical first said, “There is no national register for local total knee replacements currently, but with an estimated 8 000 to 10 000 total knee replacements taking place in South Africa each year, this technology could signal a new era in personalised joint replacement,”

According to McCready, the technologically advanced system for total knee replacement is already well established in Europe, the United States and the United Kingdom. The system, which can also be used for hip and partial knee replacements, was used in over 250 000 procedures internationally last year alone.

He explained that one of the major advantages of the robotic-assisted surgical system is that, prior to the surgery, it draws data from computed tomography (CT) scan of the patient’s knee to develop a three-dimensional pre-operative plan that is unique to each individual. “This technology determines the dimensions for the surgical cuts to the bone surfaces so that the best-sized implanted joint components can be selected for each patient, and the placement and alignment of the implanted components can be planned in advance,” he said.

“During the operation, the robotic arm system provides detailed visual, auditory and tactile feedback to the surgeon, which helps to enhance surgical precision in positioning and aligning the knee implants. The robotic arm system, which is controlled by the surgeon at all times, provides an additional safeguard for the patient because it ensures that only the specific areas identified in the personalised pre-surgical plan can be operated on, and thus prevents damage to critical structures within the knee.”

McCready also spoke about some of the benefits of this system, “Benefits for patients that have been noted in outcomes recorded internationally for this advanced surgical option include the achievement of a better balanced and more natural feeling implanted knee, less post-operative pain and quicker recovery time.”

The managing director of Netcare’s hospital division, Jacques du Plessis, said the introduction of the robotic-assisted surgical system at Netcare Linksfield Hospital is well aligned to Netcare’s commitment to deliver personalised health and care to each individual patient. “International studies indicate that this intervention reduces the length of hospital stays and recovery times,” he said.

“By making advanced medical technology such as this available in South Africa, we look forward to realising similar benefits for our patients.”

This development has the potential to significantly enhance patient outcomes, and inappropriate cases, provides greater choice in terms of the surgical options available for individuals requiring total knee replacements, Du Plessis concluded.
