Trends in epidemiology of knee arthroplasty in the United States, 1990-2000.

Objective: There is little information on longitudinal trends in the epidemiology of total knee arthroplasty (TKA). This study was undertaken to determine whether, during the past decade, TKA rates increased in younger adults and older adults, whether utilization of TKA increased among minorities, and whether more patients underwent surgery at high-volume hospitals.

Methods: TKA cases (n = 443,008) were extracted from the 1990-2000 Nationwide Inpatient Sample database.

Male sexual function after pelvic fracture.

Fifty-one male patients with prior pelvic fracture completed a Brief Sexual Function Inventory questionnaire (BSFI) 2 years postinjury. Responses were compared to those of 53 men with ankle fractures. Patients with pelvic fracture scored significantly worse than patients with ankle fracture.
