TL;DR: Joint-preserving procedures are indicated in the treatment of precollapse disease, and studies of total joint arthroplasty have described excellent outcomes at greater than ten years of follow-up, which is a major advance and has led to a paradigm shift in treating patients.

TL;DR: This report has reviewed and analyzed recent reports concerning mechanical, anatomic, and kinematic axis/alignment schemes used in total knee arthroplasty.

TL;DR: Patients undergoing a lower-extremity total joint arthroplasty who engage in impact sports should be counseled regarding their potential increased risk of aseptic loosening; however, given the weak evidence available, it is believed that higher-level studies are necessary to clearly define the risk factors, particularly with newer-generation constructs.

TL;DR: The purpose of this article is to highlight the recent evidence concerning the treatment options across the spectrum of management of osteonecrosis of the knee including lesion observation, medications, joint preserving techniques, and total joint arthroplasties.

TL;DR: The pathophysiology of cobalt toxicity in patients with metal-on-metal hip arthroplasties is highlighted and patients with new or evolving hip symptoms with a prior history of THA warrant orthopaedic surgical evaluation.
