BACKGROUND Intravenous patient-controlled analgesia (PCA) equipment and opioid cost analyses on specific procedures are lacking. This study estimates the intravenous PCA hospital cost for the first 48 postoperative hours for three inpatient surgeries. METHODS Descriptive analyses using the Premier database (2010-2012) of more than 500 US hospitals were conducted on cost (direct acquisition an...

BACKGROUND During total hip arthroplasty (THA) drainage is used by most surgeons. However, the optimal drainage strategy remains controversial. The aim of this prospective cohort study was to determine the safety and efficacy of a four-hour drainage clamping technique in patients undergoing THA. MATERIAL AND METHODS There were 64 patients who underwent THA from March 2012 to December 2015 who w...

Background Sequential bilateral total hip arthroplasty (THA) has the potential advantages of a single operative intervention with a single hospital stay, alongside reduced costs and total rehabilitation times. Its use has been limited, however, by a theoretical increase in perioperative complications. Objective The purpose of this study was to assess functional outcomes and complications in p...

PURPOSE To assess the medium-term outcome of titanium uncemented modular tapered stems in revision total hip arthroplasty (THA). METHODS A questionnaire was mailed to 421 patients who underwent revision THA using a titanium uncemented modular tapered stem. 66 of whom underwent re-revision THA. The questionnaire was composed to reveal the Charnley classification, the modified 12-item Oxford hi...

Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are recognised and proven interventions for patients with advanced arthritis. Studies to date have demonstrated a steady increase in the requirement for primary and revision procedures. Projected estimates made for the United States show that by 2030 the demand for primary TKA will grow by 673% and for revision TKA by 601% from the ...

Purpose The aim of the current study is to report the advantage and disadvantage of total hip arthroplasty performed in direct anterior approach (DAA) by comparing it to the posterolateral approach (PLA). Materials and Methods Twenty-five hip arthroplasty done in DAA (12 total hip arthroplasty [THA] and 13 bipolar hemiarthroplasty [BHA]) were compared with the same number done in PLA (13 THA ...

In vivo linear penetration in total hip arthroplasty (THA) exhibits similar values for 28mm and 32mm femoral head diameter with considerable variations between and within the studies. It indicates factors other than femoral head diameter influence polyethylene wear. This study is intended to test the effect of patient׳s individual geometry of musculoskeletal system, acetabular cup orientation, ...
