Metal-on-metal (MOM) hip articulations represent a potential alternative to conventional metal-on-polyethylene total hip arthroplasty (THA). We performed a systematic review of the peer-reviewed literature in search of studies comparing MOM with conventional primary THA with regard to functional outcomes, radiographic outcomes, and complication rates. Four Level I randomized controlled trials r...

We surveyed 343 young women with 420 total hip arthroplasties (THAs) regarding pregnancy and childbirth after THA. The mean age at surgery was 35 years (18 to 45). The mean length of follow-up after the initial arthroplasty was 16 years (6 to 27). Of these 343 women, 47 (13.7%) had a successful pregnancy after their primary THA. The first baby after a THA was delivered vaginally in 30 patients ...

BACKGROUND The aims of this study were to assess patients' preoperative expectations of the outcome of total hip or knee arthroplasty (THA/TKA) regarding specific aspects of functioning and to determine to what extent each expectation was fulfilled after 1 year. METHODS This was a prospective cohort study. Preoperative expectations and their fulfillment after 1 year were measured with the Hos...

Long-term administration of 9-amino-1,2,3,4-tetrahydroacridine (THA) has been reported to produce marked clinical improvement in patients suffering from Alzheimer's disease. The dramatic enhancement of cognitive function seen with THA contrasts sharply with the modest improvements seen with other forms of anticholinesterase therapy, suggesting that additional mechanisms might play a role in its...

The increasing demand for total hip arthroplasty (THA) in relatively young, high-demand patients has led to the use of hard-on-hard bearing surfaces. Adverse local tissue reaction/pseudotumor and elevated serum metal ion levels are commonly reported complications encountered in metal-on-metal THA, while audible articulation and rim fracture are reported in ceramic-on-ceramic THA. For this reaso...
