TL;DR: Based on the proposed criteria, definite PJI exists when there is a sinus tract communicating with the prosthesis and a pathogen is isolated by culture from at least two separate tissue or fluid samples obtained from the affected prosthetic joint.

TL;DR: Treatment of patients with an infected total knee arthroplasty with high-dose vancomycin and gentamicin antibiotic spacers seems to be clinically safe.

TL;DR: A preoperative diagnosis of developmental dysplasia of the hip or posttraumatic arthritis, the use of a posterior approach, lengthening of the extremity, and use of an uncemented femoral implant increased the odds ratio of sustaining a motor nerve palsy.

TL;DR: Examining a large consecutive series of failed THAs undergoing revision to determine if survivorship and modes of failure differ in comparison to the current data found survivorship for revision total hip arthroplasty using second revision as endpoint was 82% at 10 years.

TL;DR: Treatment options include impaction grafting and cementation of the acetabulum, noncemented hemispheric acetabular reconstruction, structural allograft reconstruction,Noncemented reconstruction with modular porous metal augments, ring and cage reconstruction, oblong cup reconstruction, cup‐cage reconstruction, and triflange reconstruction.
