The Elective Orthopaedic Centre at Orpington Hospital has installed the Stryker Mako robotic-arm system, becoming the first NHS site in South East London to offer robot-assisted joint replacement. For a trust managing around 100 procedures a year through the new technology, the move sits at the intersection of surgical precision, workforce training and the NHS’s broader push to get patients home faster.

Orpington Hospital Becomes First in South East London to Offer Robotic Joint Surgery

Joint replacement surgery has always relied on a combination of surgical judgement and manual precision, with outcomes shaped as much by the accuracy of implant positioning as by the skill of the surgeon holding the instruments. 

At Orpington Hospital, that equation has just changed. The Elective Orthopaedic Centre, run by King’s College Hospital NHS Foundation Trust, has become the first NHS centre in South East London to introduce robot-assisted surgery for hip and knee replacement, using the Stryker Mako system to guide procedures with a degree of accuracy that manual technique cannot consistently replicate.

A First For South East London’s Orthopaedic Care

Orpington Hospital is a specialist, purpose-built facility dedicated to planned inpatient and day-case bone and joint surgery, which makes it a natural testing ground for technology aimed squarely at elective orthopaedics. The trust expects to carry out around 100 procedures a year using the Mako system initially, focused on total hip, total knee and partial knee replacement. That is a modest starting volume against the scale of the NHS’s orthopaedic caseload nationally, but the significance lies less in throughput than in precedent. South East London has not previously had access to robotic-assisted joint replacement within the NHS, and Orpington’s adoption puts it ahead of neighbouring trusts still working through business cases and staff training pathways of their own.

How the Technology Actually Works

The Mako system builds a three-dimensional model of a patient’s joint from a pre-operative scan, allowing surgeons to plan implant position before they ever pick up an instrument. During surgery, a robotic arm provides tactile feedback as damaged bone is removed, helping to protect surrounding healthy tissue, while cameras track the patient’s position in real time and adjust automatically if the limb moves. The practical effect is that the system maintains a constant, computer-verified understanding of exactly where the bone sits, reducing the room for the small positional errors that can affect implant longevity and post-operative function.

What Precision Surgery Means for Recovery and Discharge

Mr Abhinav Gulihar, Clinical Director of Orthopaedics at King’s College Hospital NHS Foundation Trust, said the introduction of robotic surgery reflects years of staff training and represents an exciting moment for the department, with plans to widen access to all suitable arthroplasty patients as more clinicians complete training. Dr Anneliese Rigby, Consultant Anaesthetist at the trust, said the technology offers a more precise approach to hip and knee replacement, with the aim of reducing post-operative pain and potentially speeding up recovery.

That framing matters for a system under sustained pressure to shorten hospital stays without compromising safety. Faster, less traumatic recovery after joint replacement reduces the risk of complications linked to prolonged immobility and shortens the window before a patient can safely return home, which in turn eases bed pressure across the wider trust. It is a theme that connects directly to the NHS’s growing investment in home-based recovery models, where the same underlying logic, getting patients out of hospital beds sooner without increasing clinical risk, is being applied through virtual wards and remote monitoring rather than surgical precision.

The Workforce and Training Question

Robotic systems do not remove the need for skilled clinicians; they demand a different kind of expertise. Gulihar’s comment that many team members have spent years training for this technology is a reminder that robotic adoption in the NHS tends to be gated by workforce capacity rather than procurement budgets alone. Surgeons, theatre staff and anaesthetic teams all require dedicated training before a system like Mako can be used safely and at scale, and that training pipeline will determine how quickly Orpington’s initial hip and knee focus expands into the wider arthroplasty caseload the trust has said it hopes to reach.

Where This Fits Within Wider NHS Investment

Orpington’s robotic theatre sits within a broader pattern of capital investment in NHS infrastructure and technology, including the government’s decade-long capital strategy aimed at modernising ageing estates and expanding surgical and diagnostic capacity. It also echoes a wider international trend toward technology that compresses the gap between hospital-level care and home recovery, visible in initiatives such as Philips’ hospital-at-home consortium in Sweden, where continuous remote monitoring is being used to safely manage complex patients outside acute settings.

Future Outlook

Matthew Trainer, Chief Executive of King’s College Hospital NHS Foundation Trust, said the project reflects the hard work of a team that has put patients first, and that the trust can now build on it by training the next generation of specialists in the field. Whether Orpington’s 100 annual cases grow into a service covering the full arthroplasty caseload will depend on training capacity, theatre scheduling and whether early outcomes data supports the recovery gains clinicians are anticipating.

For commissioners and neighbouring trusts, Orpington’s launch offers an early South East London reference point for what robotic-assisted orthopaedics looks like in practice, and how quickly the promised recovery benefits translate into measurable reductions in length of stay.
