Satisfaction Rates and Quality of Life Changes Following Total Knee Arthroplasty in Age-Differentiated Cohorts.

Background: Comparisons of satisfaction rates following total knee arthroplasty (TKA) among large, age-differentiated, rigorously matched cohorts are lacking. Therefore, we compared satisfaction rates following TKA in large, age-differentiated, propensity score-matched cohorts.

Methods: We identified primary TKAs performed for non-inflammatory arthritis in patients of ages 18-55 or 65-75, yielding 529 younger and 2001 older patients.

Utilizing Dual Mobility Components for First-Time Revision Total Hip Arthroplasty for Instability.

Background: Dislocation following total hip arthroplasty (THA) remains a significant clinical problem. Few studies have focused on the use of dual mobility (DM) components in the setting of first-time revision for instability following THA. Here, we investigate patient outcomes following first-time revision THA with DM components for a diagnosis of instability.

Using a non-invasive secure skin closure following total knee arthroplasty leads to fewer wound complications and no patient home care visits compared to surgical staples.

Background: Superficial wound complications occur in up to 10% of total knee arthroplasty (TKA) procedures and have been associated with periprosthetic joint infection. The ideal material for TKA closure should offer: 1) fast intraoperative application, 2) minimal wound complications and 3) removable by patients without assistance. We evaluated a novel, non-invasive, removable skin closure system for TKA to determine its effect on wound complications.

Success rates, characteristics, and costs of articulating antibiotic spacers for total knee periprosthetic joint infection.

Background: The optimal type, characteristics, and success rates of articulating antibiotic spacers used during total knee arthroplasty (TKA) periprosthetic joint infection (PJI) have not been well defined in a single series. We sought to (1) determine the success rate for three unique spacer constructs and (2) evaluate any microbiological, surgical, or patient characteristics that would influence the success rate.

Methods: We retrospectively reviewed patients who underwent a two-stage exchange for a TKA PJI with a prefabricated spacer (PREFAB), home-made mold (MOLD), or autoclaved femoral component (AUTOCL).
