Multicenter StudyThe John Insall Award: control-matched evaluation of painful patellar Crepitus after total knee arthroplasty.
Patellar crepitus (PC) is reported in up to 14% of subjects implanted with cruciate-substituting total knee arthroplasty (TKA). Numerous etiologies of PC have been proposed. ⋯ Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Comparative StudyPerioperative complications of simultaneous versus staged unicompartmental knee arthroplasty.
The complication risk of staged versus simultaneous total knee arthroplasty continues to be debated in the literature. Previous reports suggest unicompartmental knee arthroplasty provides a more rapid functional recovery than total knee arthroplasty. However, little data exist on whether simultaneous unicompartmental knee arthroplasty can be performed without increasing the perioperative risk compared with staged unicompartmental knee arthroplasty. ⋯ Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Comparative StudyHospital economics of primary total knee arthroplasty at a teaching hospital.
The hospital cost of total knee arthroplasty (TKA) in the United States is a major growing expense for the Centers for Medicare & Medicaid Services (CMS). Many hospitals are unable to deliver TKA with profitable or breakeven economics under the current Diagnosis-Related Group (DRG) hospital reimbursement system. ⋯ Level III, Economic and Decision Analyses. See Guidelines for Authors for a complete description of levels of evidence.

Multicenter StudyA second decade lifetable survival analysis of the Oxford unicompartmental knee arthroplasty.
The role of unicompartmental arthroplasty in managing osteoarthritis of the knee remains controversial. The Oxford medial unicompartmental arthroplasty employs a fully congruent mobile bearing intended to reduce wear and increase the lifespan of the implant. Long-term second decade results are required to establish if the design aim can be met. ⋯ Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Comparative StudyDo ion levels in hip resurfacing differ from metal-on-metal THA at midterm?
Metal-on-metal Birmingham hip resurfacing (MOM-BHR) is an alternative to metal-on-metal total hip arthroplasty (MOM-THA), especially for young and/or active patients. However, wear resulting in increased serum ion levels is a concern. ⋯ Level III, therapeutic study. See the Guidelines for Authors for a complete description of level of evidence.
