Background: Massive endoprostheses provide orthopaedic oncologists with many
reconstructive options after tumor resection, although failure rates are high. Because the …

Osteoarthritis is the most common form of arthritis, affecting millions of people in the United
States. It is a complex disease whose etiology bridges biomechanics and biochemistry …

Revision knee data from six joint arthroplasty centers were compiled for 2010 and 2011 to
determine mechanism of failure and time to failure. Aseptic loosening was the predominant …

The incidence of failure after knee replacement is low, yet it has been reported that more
than 22,000 knee replacements are revised yearly. The purpose of the current study was to …

Six thousand four hundred eighty-nine knee replacements were done in 6120 patients at the
authors' institution between 1993 and 1999. Operations were done in a theater with vertical …

Background Total knee arthroplasty (TKA), aiming at neutral mechanical alignment (MA),
inevitably modifies the patient's native knee anatomy. Another option is kinematic alignment …

Despite technical improvements, revision rates for total knee arthroplasties (TKAs) remain
high. Our goal was to report the reason (s) for revision TKA in a large, current, multicenter …

Osteoarthritis (OA) is currently defined by the American College of Rheumatology as a
“heterogeneous group of conditions that leads to joint symptoms and signs which are …

Background: Failure of total knee arthroplasty is problematic. The purpose of this study was
to evaluate the factors that influence the durability of a primary total knee prosthesis …

Introduction: After a better understanding of normal knee anatomy and physiology, the
Kinematic Alignment (KA) technique was introduced to improve clinical outcomes of total …
