AMIS (Anterior Minimally Invasive Surgery) Experience is more than an anterior approach, it is a complete platform uniquely complemented by a tailored education program and a comprehensive package of implants, instruments and digital solutions, to address the specific needs of patients, surgeons and care facilities.

This minimally invasive approach has been widely embraced by the orthopaedic community, and it has been chosen by surgeons to be used with more than 500,000 patients worldwide.





The AMIS Experience is much more than a surgical technique. Browse the below tabs to discover more about this comprehensive platform.





The AMIS technique potentially delivers several benefits to patients, surgeons and care facilities, including:

  • Shorter rehabilitation and faster return to daily activities[3,6]
  • Decreased post-operative pain[7]
  • Reduced risk of dislocation[3,7,8]
  • Less blood loss[8]
  • Shorter hospital stay[8]
  • Medium- to long-term benefits[9,10,11]
  • Economic benefits[12,13]

Discover more about the benefits delivered by the AMIS, reading the latest version of the AMIS Publication Review.




Get M.O.R.E. from the Anterior Approach

Discover our continuous education opportunities designed to master the AMIS approach from the simplest primary hip arthroplasties to the most complex cases. No capsular release, bikini incision and Revision THA are just some examples of the techniques featured at our events, where you can share your experience and learn from other experts. 


How to maximize the Anterior Approach for hip replacement - The AMIS revolution

The development of a standardized and simplified surgical technique for the anterior approach, with specific instrumentation and a personalized education program – the AMIS approach – strives to further respect the periarticular structures, in particular the capsule, usually released to efficiently expose the femur. In fact, a reduced capsular release potentially results in less bleeding and better hip functionality.



If the AMIS technique is no longer a secret to you, then challenge yourself with the ultimate next step: the AMIS Bikini. 
AMIS Bikini represents the natural evolution of the AMIS approach, following the same intermuscular pathway but utilizing an inguinal skin incision. Dedicated instruments and a tailored education path, are available to facilitate the surgical procedure and streamline the learning path.

“The AMIS procedure completely revolutionized my surgical care for my arthritic hip patient population. Prolonged hospital stays, weight-bearing and position restrictions, and intense narcotic usage are historical remnants of antiquated surgical care. Instead, I offer patients the opportunity to go home on the same day of surgery, with no restrictions and no opioid pain medications. I have changed my technique, and my patients and I have benefited from it. It’s a powerful win-win!”

Tyler Goldberg, MD

“Not only simple surgeries, but also complex primary cases and revisions could be performed with AMIS. In the last 10 years the instrument set has become more and more efficient, and the AMIS offering has further evolved with the introduction of the Bikini platform and the no capsular release technique”

Dr. Frederic Laude


“What I really love about the AMIS is the true muscle-sparing nature of the approach, and the way soft tissue structures can be preserved. This leads to a lower dislocation risk for my patients, which is crucial for both their satisfaction and implant performance. Thanks to AMIS, my patients recover quickly and potentially can return home earlier. They are in less pain, and there is less tissue trauma around the hip.”

Prof. Dr. med. Patrick Zingg


“After I participated in a Learning Center in France in 2007, I immediately decided to continue with AMIS. The comprehensive AMIS Education program is an essential pillar and makes it possible for surgeons to take full advantage of the benefits offered by the AMIS approach. The program reduces the learning curve, provides ongoing support, and helps to prevent potential intraoperative complications, particularly during the first cases.”

Prof. John O’Donnell
