Two studies demonstrating that ‘robotic assistance enhances implant positioning, alignment and ligament balance’ have been positively received by experts.
Both highlight the capacity to replicate the natural human anatomy accurately.
The Hospital for Special Surgery (HSS) presented this fresh evidence at the American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting in San Francisco, US.
The research sheds light on the advantages of robotic-assisted joint replacement surgery.
The retrospective studies conducted by HSS investigators focused on outcomes in knee and hip replacement surgeries performed with robotic assistance.
Dr David J Mayman, chief of the Adult Reconstruction and Joint Replacement Service at HSS, emphasised the significance of their findings: ‘Robotic assistance leads to improved implant positioning, alignment and ligament balance, allowing us to replicate the patient’s natural anatomy better.’
The first study, led by Dr Seth A Jerabek, examined the impact of surgical robots on total knee replacement surgeries.
Analysis of 21,000-plus cases revealed a notable reduction in the need for manipulation under anaesthesia (MUA) post-surgery when robotic assistance was utilised.
Dr Jerabek explained that this decrease in MUA requirements highlights the potential of robotic technology to enhance recovery and reduce patient discomfort.
The second study, spearheaded by Dr Elizabeth B Gausden, compared outcomes of anterior versus posterior approaches in robotic-assisted total hip replacement (THR) surgeries.
Contrary to previous beliefs, the research found no significant difference in the rates of complications between the two approaches.
Dr Gausden emphasised that both approaches yield excellent outcomes when performed by experienced surgeons, with robotic technology crucial in ensuring stability and reducing the risk of postoperative issues.
Dr Mayman emphasised the need for continued research to evaluate long-term outcomes of robotic-assisted joint replacement surgeries.
He said: ‘As the use of robotic assistance in joint replacement surgery becomes more common, future studies should evaluate outcomes over longer periods of time. As a leader in using this technology, HSS continues to study various robotic systems to acquire the data needed to provide the evidence-based care that will benefit our patients.’
HSS is the world’s leading academic medical centre focused on musculoskeletal health. Dr Mayman reiterated the hospital’s commitment to exploring various robotic systems to provide evidence-based care that benefits patients.
As the use of robotic assistance in joint replacement surgeries becomes increasingly prevalent, the insights provided by these studies are poised to shape the future of orthopaedic surgery, promising improved outcomes and enhanced patient experiences.
