Robotic-Assisted Joint Replacement
The most significant advance in joint replacement of the past decade. Systems like Mako (Stryker) and ROSA (Zimmer Biomet) allow pre-operative 3D planning based on the patient's CT scan, and then guide the surgeon's instruments within the planned boundaries during surgery.
What Robotic Surgery Achieves
- Implant alignment accuracy within 1-2 degrees — impossible with conventional instruments
- Personalised bone resection based on individual anatomy
- Soft tissue balancing assessment during surgery
- Reduced post-operative pain due to less bone trauma
- Faster recovery and longer implant survival
Who Benefits Most from Robotic Surgery
All patients benefit from improved alignment. Younger, more active patients benefit most from improved implant survival. Patients with complex deformities benefit from precise pre-planning capability.
Advanced Implant Materials
Oxidized Zirconium (Oxinium)
A metal alloy with a ceramic-like surface — dramatically reduces polyethylene wear. Ideal for younger, more active patients who need their implant to last 25+ years.
Highly Cross-Linked Polyethylene
The bearing surface of modern implants. Radiation cross-linking creates a plastic that is 10-100x more wear-resistant than conventional polyethylene, significantly extending implant life.
Enhanced Recovery After Surgery (ERAS) Protocols
Standardised pre- and post-operative care pathways that minimise pain, reduce blood loss, encourage early mobilisation, and allow discharge in 2-3 days. Components include spinal anaesthesia with nerve blocks, tranexamic acid for blood conservation, and same-day physiotherapy.
