In surgery, skill defines a surgeon. But innovation defines outcomes.
2 years ago, I had the privilege of performing India’s first Direct Anterior Approach (DAA) Total Hip Replacement using the PURIST Leg Positioning System. Since then, I have continued to integrate this technology into every DAA hip replacement, and the results have been transformative.
Why the PURIST?
Developed by Innovative Orthopedic Technologies (IOT) in Switzerland, the PURIST is a next-generation leg positioning system designed specifically for anterior hip replacement. Unlike conventional methods that rely on manual assistance, the PURIST enables all essential DAA movements on a controlled, graduated scale—with up to 180° rotation, 130 mm traction, full extension, and 40° adduction/abduction.
This precision matters. With millimeter-level accuracy, the system allows me to:
🔹 Position implants with reproducibility and confidence
🔹 Perform traction, rotation, and stability testing intra-operatively
🔹 Minimize trauma to muscles and soft tissue by avoiding unnecessary manipulation
🔹 Reduce dependence on non-sterile assistants for critical leg movements
In a busy operating room, it is equally impressive. Setup takes only minutes, it works with any standard OR table, small footprint, and its Fast Track Hybrid System ensures simultaneous traction and rotation while automatically adjusting traction during extension. This consistency allows me to deliver the same high standard of care, surgery after surgery.
For patients, the benefits are clear:
✅ Smaller incision
✅ Muscle preservation
✅ Reduced risk of dislocation
✅ Faster recovery
✅ Less postoperative pain
The PURIST is not just an instrument—it represents a shift towards precision-driven, muscle-sparing surgery. Widely adopted in the West, it is now shaping outcomes for Indian patients as well.
Bringing this technology home was not just about being “the first.” It was about bridging the gap between global innovation and Indian patient care. And every time I see a patient walking confidently within days of surgery, I am reminded why innovation must always go hand in hand with skill.
