Are outcomes after total knee arthroplasty worsening over time? A time-trends study of activity limitation and pain outcomes.
The authors examined whether function and pain outcomes of patients undergoing primary total knee arthroplasty (TKA) are changing over time. Using Mayo Clinic Total Joint Registry data, they found that patient-reported function and pain outcomes after primary TKA have worsened over the study period 1993-95 to 2002-05; this time-trend is independent of changes in preoperative pain/limitation and certain patient characteristics.

Variation in hospital inpatient prices across small geographic areas.
The authors examined whether market competition may influence the difference in the inpatient price per discharge between public and private payers across small geographic areas. They found greater geographic variation in the inpatient price per discharge among private than public payers for most hospital services, while hospitals in more concentrated markets were associated with a higher price per discharge among knee arthroplasty discharges for both payers. They concluded that hospitals charged significantly higher prices to private than public payers.

Part II: managing perioperative hyperglycemia in total hip and knee replacement surgeries.
Perioperative hyperglycemia management is an important factor in reducing the risk of surgical site infections (SSIs) in all patients whether they have diabetes or not. This article describes the impact of an evidence-based practice standard for perioperative hyperglycemia management in the reduction of SSIs in patients having total hip and knee replacement surgery.
