Corin launches Optimized Positioning System (OPS™) for hip replacement at AAOS

Ground-breaking Technology Enables Surgeons to Determine Optimal Implant Positioning Based on How a Patient Moves

Every patient moves differently, and now surgeons can take this into account when performing hip replacement surgery thanks to a new technology from Corin Group that helps determine the best positioning of an implant and its components based on how patients really move during daily activities.

Corin announced the U.S. launch of its Optimized Positioning System (OPS) System at the American Academy of Orthopaedic Surgeons (AAOS) in San Diego. The technology may lead to one of the most significant changes to the way hip replacements are performed in more than 30 years.

'This new technology challenges the traditional approach of placing implants in generic safe zones,'said James Huddleston III, MD, associate professor of orthopaedic surgery at the Stanford University Medical Center. 'Now we can get more specific and tailor the implant position for each patient. This should help reduce the dislocation rate and even possibly reduce wear.'

Utilizing pre-operative functional simulation and planning and a unique intra-operative positioning system that employs 3D printing and laser guidance, OPS helps surgeons determine the best position and orientation for a hip implant based on specific patient anatomy and movement.  

'While hip replacement surgery is considered one of the most successful operations in medical history, we are always looking for ways to improve it, particularly ways we can improve function and performance and reduce the potential for dislocation and premature wear of bearing surfaces,' said Douglas Dennis, MD, an orthopaedic surgeon in Denver, CO. 'This new technology may be an advance that helps us do this.'

In the U.S., the first-ever functional, patient-specific hip replacement procedures using OPS were performed in November 2016, shortly after FDA clearance. More than 3,000 procedures have been done in Europe and Australia, where the system was previously approved for use.

'No two patients are the same. We are offering a patient-specific solution that gives the surgeon the information and tools necessary to enable an optimal hip replacement procedure,' said Paul Berman, President Corin USA. 'Feedback from surgeons who have used OPS has been excellent and interest in the system from the orthopaedic community is very high.'
