Dissociation of Acetabular Polyethylene Liners With a Morse Taper Design.

Background: Polyethylene liner dissociation is an uncommon complication of hip replacement. Dissociation has been associated with particular acetabular component designs. This study reviewed acetabular liner dissociations in a specific modular cup with a Morse taper locking mechanism that has not been previously reported.

The Atypical Patient With Slipped Capital Femoral Epiphyses May Be at Increased Risk for a Missed Contralateral Slip.

Slipped capital femoral epiphysis (SCFE) is a commonly encountered hip disorder. The goal of this study was to describe the incidence of missed contra-lateral SCFE as well as to identify risk factors. The authors hypothesized that contralateral slips are more often missed in patients with severe involvement of the treated side.

Readability of Patient Educational Materials for Total Hip and Knee Arthroplasty.

This study aimed to evaluate patient education materials that are focused on total hip arthroplasty (THA) and total knee arthroplasty (TKA) using health literacy best practices and plain language principles as frameworks. Readability assessments were conducted on a sample of nine patient education documents that are commonly given to THA and TKA surgery patients. Mean readability scores were compared across the sample.
