Randomized Controlled Trial Multicenter Study Comparative StudyCemented versus uncemented hemiarthroplasty for displaced femoral neck fractures: 5-year followup of a randomized trial.
Displaced femoral neck fractures usually are treated with hemiarthroplasty. However, the degree to which the design of the implant used (cemented or uncemented) affects the outcome is not known and may be therapeutically important. ⋯ Level I, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Multicenter StudyRisk factors for revision within 10 years of total knee arthroplasty.
An in-depth understanding of risk factors for revision TKA is needed to minimize the burden of revision surgery. Previous studies indicate that hospital and community characteristics may influence outcomes after TKA, but a detailed investigation in a diverse population is warranted to identify opportunities for quality improvement. ⋯ Level III, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.

Medial open wedge high tibial osteotomy: can delayed or nonunion be predicted?
The opening wedge approach to high tibial osteotomy (HTO) is perceived to have some advantages relative to the closing wedge approach but it may be associated with delayed and nonunions. Because nonunions evolve over months, it would be advantageous to be able to identify risk factors for and early predictors of nonunion after medial opening wedge HTO. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

ReviewTrapeziometacarpal joint stability: the evolving importance of the dorsal ligaments.
Trapeziometacarpal (TMC) arthritis of the thumb is a common source of hand pain and disability. TMC ligamentous instability may play a role in TMC degeneration. However, the relative importance of the TMC ligaments in the etiology of degeneration and the use of surgery to treat instability in early-stage arthritis are unclear. ⋯ The dorsal ligaments are the primary stabilizers of the TMC joint. Ligament reconstruction and metacarpal osteotomy ameliorate ligamentous laxity and relieve pain based on Level IV studies.
