RESUMO
This study assessed the early outcomes of total hip arthroplasty compared with body mass index (BMI). 5357 hip arthroplasties were evaluated. Oxford Scores, revision for any reason and other factors including American Society of Anaesthesiology scores, length of surgery and cementation of components were analyzed. Both a high and a low BMI predicted for worse Oxford Hip Scores. Obese and morbidly obese patients had significantly lower six month Oxford Scores than healthy patients, the lowest survival, were younger than all other groups and had greater proportions with fully un-cemented prostheses. At this early stage, the results show that outcome and early revision are statistically and clinically poorer for obese patients.

The term pseudotumor was coined by Pandit et al (J Bone Joint Surg Br. 2008; 90:847) to describe the features of a soft tissue mass, which is neither infective nor malignant, that is found in association with hip arthroplasty. Most previously reported cases have been associated with a metal-on-metal articulation, with the largest series occurring after hip resurfacing. The author describes a patient who developed a pseudotumor secondary to particulate disease arising after polyethylene liner wear that led to a metal-on-metal articulation in conventional hip arthroplasty.
