Perioperative and Early Postoperative Comparison of a Modern Cemented and Cementless Total Knee Arthroplasty of the Same Design.

Background: Cementless total knee arthroplasty (TKA) designs that incorporate a highly porous, titanium surface have the potential to achieve biologic fixation and improve component survivorship. This study's purpose was to compare perioperative and early postoperative outcomes of a cemented vs cementless TKA of the same design.

Methods: This was a retrospective review of a consecutive series of TKAs performed at a single institution using a cemented or cementless TKA of the same design (Triathlon, Stryker Inc, Mahwah, NJ).

Failure at the Tibial Cement-Implant Interface With the Use of High-Viscosity Cement in Total Knee Arthroplasty.

Background: Recent literature has shown debonding of the tibial implant-cement interface as a potential cause for implant loosening. The purpose of this case series is to report this phenomenon in a historically well-performing implant when used with high-viscosity cement (HVC).

Methods: Thirteen primary cemented Biomet Vanguard total knee arthroplasties were referred to 1 of 2 institutions with complaints of persistent pain after their index procedure.

Computer access and Internet use by urban and suburban emergency department customers.

Background: Patients are increasingly using the Internet (43% in 2000 vs. 70% in 2006) to obtain health information, but is there a difference in the ability of urban and suburban emergency department (ED) customers to access the Internet?

Study Objective: To assess computer and Internet resources available to and used by people waiting to be seen in an urban ED and a suburban ED.

Methods: Individuals waiting in the ED were asked survey questions covering demographics, type of insurance, access to a primary care provider, reason for their ED visit, computer access, and ability to access the Internet for health-related matters.
