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.

The Salto total ankle arthroplasty: survivorship and analysis of failures at 7 to 11 years.
Despite the appearance of new-generation, mobile-bearing, cementless prostheses, total ankle arthroplasty remains controversial. Among the criteria guiding the choice between arthrodesis and arthroplasty, the long-term survival and postoperative function are of critical importance. The mobile-bearing Salto prosthesis has been used in Europe since 1997, but only 2 to 5 years of followup data have been reported. ⋯ Level IV, therapeutic study. See 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.

Management of intraoperative medial collateral ligament injury during TKA.
Intraoperative injuries to the medial collateral ligament are often unrecognized and failure to appropriately manage ligament loss may result in knee instability and loosening. ⋯ Level IV, therapeutic study. 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.
