Utility of Synovial White Blood Cell Count and Differential Before Reimplantation Surgery.

Background: Determining optimal timing of reimplantation during 2-stage exchange for periprosthetic joint infection (PJI) remains elusive. Joint aspiration for synovial white blood cell (WBC) count and neutrophil percentage (PMN%) before reimplantation is widely performed; yet, the implications are rarely understood. Therefore, this study investigates (1) the diagnostic yield of synovial WBC count and differential analysis and (2) the calculated thresholds for persistent infection.

Length of stay after shoulder arthroplasty-the effect of an orthopedic specialty hospital.

Background: One potential avenue for the realization of health care savings is reduction in hospital length of stay (LOS). Initiatives to reduce LOS may also reduce infection and improve patient satisfaction. We compare LOS after shoulder arthroplasty at an orthopedic specialty hospital (OSH) and a tertiary referral center (TRC).

Workers' Compensation patients after total joint arthroplasty: do they return to work?

Clinicians identify patients receiving Workers' Compensation (WC) as unlikely to fully benefit from total joint arthroplasty (TJA), with possibly decreased ability to return to work. We completed follow-up for 164 patients undergoing 177 arthroplasties while receiving WC between 2000 and 2009. Inquiry was made regarding work status, nature of work, and return to work time frame.
