Multicenter StudyAge and obesity are risk factors for adverse events after total hip arthroplasty.
Defining the epidemiology of adverse events after THA will aid in the development of strategies to enhance perioperative care. ⋯ Older and obese patients should be counseled regarding their increased risk for the development of adverse events after THA. The cause of the decline in the rate of adverse events between two time periods is unclear and warrants further investigation to confirm and identify the cause.

Multicenter StudyPelvic discontinuity treated with custom triflange component: a reliable option.
Pelvic discontinuity is an increasingly common complication of THA. Treatments of this complex situation are varied, including cup-cage constructs, acetabular allografts with plating, pelvic distraction technique, and custom triflange acetabular components. It is unclear whether any of these offer substantial advantages. ⋯ Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Comparative StudyA short tapered stem reduces intraoperative complications in primary total hip arthroplasty.
While short-stem design is not a new concept, interest has surged with increasing utilization of less invasive techniques. Short stems are easier to insert through small incisions. Reliable long-term results including functional improvement, pain relief, and implant survival have been reported with standard tapered stems, but will a short taper perform as well? ⋯ Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

A new high-flexion knee scoring system to eliminate the ceiling effect.
Various scoring systems document improvement after TKA, but most are associated with a ceiling effect that may fail to distinguish between patients having different levels of knee function after TKA. We therefore developed a new scoring system for patients with higher levels of flexion to eliminate ceiling effects observed with current systems. ⋯ Level III, diagnostic study. See Guidelines for Authors for a complete description of levels of evidence.
