Introduction

Depression is a common co-morbidity in Total Hip Arthroplasty (THA). Chronic pain and depression influence one another. Postoperative outcomes and satisfaction rates are affected by depression.

Objectives

The aim of the study was to determine the impact of pre-operative depression on patient functional outcomes and satisfaction rates after THA. A secondary objective was to assess potential change in the incidence of depression at mid-term post-operative follow-up.

Background

The prevalence of immunocompromised patients undergoing Total Hip Arthroplasty (THA) is increasing worldwide as a consequence of advances in treatment. HIV is presenting in an older population group and concerns of higher rates of infection, early failures and dangers posed to healthcare workers exist. This study is imperative to predict future burden of THA and make subsequent provisions

Objectives

The objective was to determine the seroprevalence of HIV in patients presenting for THA in an academic institution in a developing country. Secondarily, the aim was to determine if there is any difference in the seroprevalence of patients undergoing THA and TKA and finally to assess the status of disease control in seropositive patients eligible for TJA on pre-existing HAART.

This study reports on ceramic-on-metal (CoM) bearings in total hip replacement. Whole blood metal ion levels were measured. The median increase in chromium and cobalt at 12 months was 0.08 μg/1 and 0.22 μg/1, respectively, in CoM bearings. Comparable values for metal-on-metal (MoM) were 0.48 μg/1 and 0.32 μg/1. The chromium levels were significantly lower in CoM than in MoM bearings (p = 0.02). The cobalt levels were lower, but the difference was not significant. Examination of two explanted ceramic heads revealed areas of thin metal transfer. CoM bearings (one explanted head and acetabular component, one explanted head and new acetabular component, and three new heads and acetabular components) were tested in a hip joint simulator. The explanted head and acetabular component had higher bedding-in. However, after one million cycles all the wear rates were the same and an order of magnitude less than that reported for MoM bearings. There were four outliers in each clinical group, primarily related to component malposition.
