Every patient has a unique pelvic motion and physiological profile which can impact success of a Total Hip Replacement.
OPS™ is a two staged technology intended for use by orthopaedic surgeons to aid in the treatment of patients undergoing total hip replacement.
Stage 1 is a Dynamic Hip Analysis which provides information on the patient’s predicted biomechanics, displaying how the hip joint will be loaded post-operatively relative to varying orientations of the acetabular cup. The analysis is generated from patient X-ray and CT scans and delivered to the surgeon in a digital format.
Stage 2 is the Delivery System which enables accurate implant positioning in surgery using a 3D printed patient specific guide.

  • The current theory on implant positioning during conventional Total Hip Replacement surgery is based on a generic approach that suggests there is a 'safe window' for cup orientation that suits all patients. Implants are typically orientated either with jigs, freehand or using computer navigation. Computer navigation adds accuracy but is costly and adds time & complexity to surgery. OPS™ is a patient specific dynamic analysis that is performed prior to surgery. Based on the patient's kinematic profile an intended cup orientation can be determined pre-operatively. Patient specific guides are then used during surgery to deliver this intended cup orientation. OPS™ is a first of its kind.

  • OPS™ provides surgeons with a solution to address a real clinical need. Orthopaedic surgeons currently have no knowledge of how an individual patient's pelvis moves and how to position their acetabular cups accordingly. Corin OPS™ provides the surgeon more information on their patient's dynamics than has ever been available before. Unlike the predicate technology OPS™ enables decentralisation of healthcare. The technology can be used within any operating theatre around the world and does not rely expensive, complex equipment located within a premium healthcare facility, shifting surgical complexity from the expensive intra-operative environment to the pre-operative environment.

  • The orientation of the acetabular cup is critical to the success of a total hip replacement. Mal-positioning of acetabular cups has been linked to dislocation, impingement, wear or osteolysis which can ultimately lead to revision surgery. While surgical technique has been linked errors in component positioning, a lack of consensus on planned cup orientation, referencing systems or surgical techniques also contribute to mal-positioning. OPS™ offers an improved understanding in actetabular cup positioning which reduce the risks associated with the edge-loading of implants which can lead to improvements in patient outcomes and quality of life. OPS™ enables the personalisation of patient care.

  • Optimized Ortho, the manufacturer is a start-up research and development company based in Sydney Australia. The OPS technology platform was initially utilised by Corin Australia under an exclusive agreement with Optimized Ortho throughout the 2014 calendar year. Following the success within the Australian marketplace, Corin Group PLC (UK) the global manufacturer of Corin orthopaedic devices acquired Optimized Ortho on the 25th November 2014 with plans to release OPS™ globally. Initial OPS™ surgeries have taken place in the UK at Oxford University and further cases have been performed in London, UK and on the European mainland. Plans to release the technology to the USA is pending FDA 510K approval.

    The OPS™ technology platform has been enabled through advances in 3D imaging and improvements in computational efficiency. Engineering techniques derived from aerospace and automotive industries have been used to develop patented kinematic simulation software. The Patient Specific Guides are fabricated from the latest 3D printing techniques using biocompatible materials OPS™ software and patient specific guides have been designed and manufactured in compliance to international standards and regulations.
