Randomized Controlled Trial Multicenter StudyCeramic bearings for total hip arthroplasty have high survivorship at 10 years.
Ceramic bearings were introduced to reduce wear and increase long-term survivorship of total hip arthroplasty. In a previous study comparing ceramic with metal-on-polyethylene at 5 to 8 years, we found higher survivorship and no osteolysis for the ceramic bearings. ⋯ Level I, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

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.

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.

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.

Predictors of participation in sports after hip and knee arthroplasty.
While the primary objective of joint arthroplasty is to improve patient quality of life, pain, and function, younger active patients often demand a return to higher function that includes sporting activity. Knowledge of rates and predictors of return to sports will help inform expectations in patients anticipating return to sports after joint arthroplasty. ⋯ Level II, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence.
