[Organizational climate in management teams and its relationship with health care outcomes].

Objective: To identify the relationship between organizational climate of management teams and the performance of health services.

Materials And Methods: A transversal and analytical study was designed. The Organizational Climate Scale (OCS) was utilized and performance was assessed by the achievement indicators through correlation analysis and multiple regression.

Influence of the tibial stem design on bone density after cemented total knee arthroplasty: a prospective seven-year follow-up study.

We prospectively measured the changes in bone mineral density (BMD) in the proximal tibia of 20 total knee arthroplasties, ten with cruciform stems and ten with cylindrical stems. The measurements were made one, four and seven years after surgery. We observed a uniform density decrease in three regions of interest from one to seven years of follow-up.

Total knee arthroplasty in the elderly. Is there an age limit?

The goal of this study was to compare the results of the total knee arthroplasty (TKA) in 2 study groups only differing by age. We have analyzed 218 TKA cases (138 women and 80 men) with at least 2 years follow-up. Mean age was 70 years (SD, 7.

Measurement of bone mineral density is possible with standard radiographs: a study involving total knee replacement.

Background: Measured bone density correlates well with the mechanical properties of the bone. Our objective was to evaluate optical densitometry as a method of measuring the periprosthetic bone density of the tibial platform in total knee replacement using serial dual-energy X-ray absorptiometry (DXA) as the reference test.

Methods: 30 patients who underwent a cemented total knee replacement were followed up for over 2 years.
