Throughout the field of orthopaedics, there is a trend moving toward preserving as much of the patient’s natural anatomy as possible. Likewise, having access to a wide range of bone conserving implants affords the surgeon the opportunity to treat each patient with respect to anatomical preservation.
Shoulder arthroplasty is currently the most effective means of treating end-stage glenohumeral osteoarthritis in modern medicine.
Anterior cruciate ligament (ACL) injuries are commonly encountered in the practice of sports medicine with current literature estimating an incidence of 100,000 to 200,000 cases per year.
As long as there have been bone voids or defects, there has been a desire to fill them. The description of filling defects with various substances has been mentioned in ancient Hindu, Egyptian and Greek texts.
Computer-assisted orthopaedic surgery (CAOS) has been shown to offer improved accuracy to total knee arthroplasty (TKA) compared to conventional techniques.1 Despite promising results, one of the drawbacks for surgeons to adopt CAOS technology may be the requirement of switching from conventional to CAOS-specific instruments.
As hospitals are facing mounting financial pressures in the current economic environment, time spent in the operating room has been identified as one of the most costly areas of hospital operations. As such, introduction of a new total knee arthroplasty (TKA) system to clinical care should demonstrate a minimum learning effort requirement.
The single-taper wedge stem design is derived from the cemented Mueller stem of the 1970s. Unlike fit-and-fill stems, which contact most of the metaphysis, tapered wedge femoral stems are designed to achieve proximal medial/lateral fixation.
