Is a cementless dual mobility socket in primary THA a reasonable option?
Dislocation after THA continues to be relatively common. Dual mobility sockets have been associated with low dislocation rates, but it remains unclear whether their use in primary THA would not introduce additional complications. ⋯ Level IV, therapeutic study.

Multicenter StudyExtent of tibiofemoral osteoarthritis before knee arthroplasty: multicenter data from the osteoarthritis initiative.
Knee arthroplasty traditionally is recommended for persons with substantial disability and disabling pain attributable to moderate or severe osteoarthritis (OA). Pain and functional status after arthroplasty may be influenced by the extent of knee OA before surgery and recent evidence suggests persons with less severe knee OA before undergoing TKA have greater pain levels and worse function than persons with more severe knee OA. ⋯ Level I, diagnostic study. See Guidelines for Authors for a complete description of levels of evidence.

The vascularized fibular graft in precollapse osteonecrosis: is long-term hip preservation possible?
Osteonecrosis of the femoral head (ONFH) is a debilitating condition affecting primarily young patients. Free vascularized fibular grafting (FVFG) may provide a durable means to preserve the femoral head. When used in the precollapse stages of ONFH, this treatment may alter the course of disease. ⋯ Level IV, therapeutic study. See Instructions to Authors for a complete description of levels of evidence.

Surgical technique: Lateral retinaculum release in knee arthroplasty using a stepwise, outside-in technique.
Lateral release of a tight lateral retinaculum in a TKA is intended to correct patellar maltracking but the widely used inside-out technique has associated risks. We describe an alternate stepwise outside-in technique, with titrated release intended to maximize the chance of preserving the superior lateral genicular artery (SLGA). ⋯ Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
