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.
