In orthopaedic surgery, precision is everything. Robotic devices are revolutionizing the field, enabling surgeons to achieve unparalleled accuracy in joint replacements and other procedures.

HISTORY / ORIGIN

The use of robots in surgery dates to the 1980s, with systems like PUMA 560 used for neurosurgical biopsies. The first orthopaedic robotic system, ROBODOC, was developed in the early 1990s for hip replacement. Since then, orthopaedic robotics has advanced dramatically, with systems like MAKO (for knee and hip replacement) and NAVIO (for partial knee replacement) becoming widely adopted. Today, orthopaedic robotic devices are a standard part of many surgical practices.

TYPES OF ORTHOPAEDIC ROBOTIC DEVICES

Orthopaedic robotic devices can be categorized by function:

Active Systems – Perform pre-programmed tasks autonomously under surgeon supervision (e.g., ROBODOC).

Semi-Active Systems – Provide guidance and assistance while the surgeon performs the procedure (e.g., MAKO, NAVIO).

Passive Systems – Provide positioning and stabilization without active cutting.

Haptic Systems – Provide tactile feedback to the surgeon.

MATERIALS / KEY FEATURES

Orthopaedic robotic devices have several key features:

Precision – Robotic systems achieve sub-millimeter accuracy.

Preoperative Planning – CT or MRI-based planning for optimal implant placement.

Real-Time Tracking – Real-time tracking of instruments and anatomy.

Haptic Feedback – Tactile feedback for a more natural surgical feel.

Minimally Invasive – Robotic systems enable minimally invasive approaches.

BENEFITS / WHY CHOOSE ORTHOPAEDIC ROBOTIC DEVICES

✅ Greater accuracy – Robotic systems achieve more accurate implant placement than manual techniques.

✅ Better outcomes – Improved implant alignment leads to better functional outcomes and longer implant life.

✅ Less variability – Robotic systems reduce variability between surgeons.

✅ Minimally invasive – Enables smaller incisions and faster recovery.

✅ Patient-specific – Preoperative planning allows patient-specific implant placement.

CARE TIPS / USAGE TIPS

Surgeon training – Surgeons require specialized training to use robotic systems.

Preoperative planning – Careful planning is essential for optimal outcomes.

Sterility – Robotic components must be sterile or sterilely covered.

Maintenance – Regular maintenance of robotic systems is essential.

Patient selection – Not all patients are candidates for robotic-assisted surgery.
