OBJECTIVE To study the HRQOL in veterans with prevalent total knee arthroplasty (TKA) or total hip arthroplasty (THA) and compare them with age- and gender-matched US population and control veteran population without these procedures. METHODS A cohort study and cross-sectional survey on veterans obtained demographics and HRQOL with Short-Form 36 for veterans (SF-36V). Veterans were categorize...

BACKGROUND AND PURPOSE Limited data exist on the natural history of thoracic kyphosis in elderly patients. The purpose of this study was to determine the statistical distribution of the thoracic kyphotic angle (TKA) measurement in older patients without vertebral body abnormalities when compared with a young population. METHODS The TKA was measured by Cobb angle on digital lateral chest radio...

BACKGROUND Total knee replacement is now the most common joint replacement procedure performed in Ontario, and many patients require bilateral replacement. However, whether bilateral total knee arthroplasty (TKA) should be staged or simultaneous is hotly debated. To determine the current common operative practices of orthopedic surgeons in Ontario, we carried out a province-wide survey. METHO...

Background The prognosis of complex primary total knee arthroplasty (TKA) with severe deformity and ligament deficiency is not clear. There a paucity evidence in the current literature on treatment outcomes rotating hinge implants TKA. aim this study was to determine mid-term clinical, radiographic, health-related quality life (HRQoL) patients who had undergone TKA using single hinged replaceme...

In vitro synergy testing using levofloxacin (LVX) plus piperacillin/tazobactam (TZP) was performed by Etest and time-kill assay (TKA) for 31 unique fluoroquinolone-resistant Pseudomonas aeruginosa isolates. The Etest method showed synergy for 9/31 (29%) of isolates, while TKA showed synergy with 14/31 (45%) of isolates. When comparing the Etest method and TKA, concordant results for synergy, an...

Background: Patellar crepitus after total knee arthroplasty (TKA) is not uncommon. The choice between patellarresurfacing or retention in TKA has remained controversial. Therefore, this randomized controlled trial aimed to evaluatethe impact of patellar resurfacing on the incidence of patellar crepitus. In addition, we compared the clinical outcomesand satisfaction between the...

Background: Periprosthetic infection is the most serious joint replacement complication, occurring in 0.8-1.9% of totalknee arthroplasties (TKAs).This review aims to define the role of preoperative aspiration culture (PAC) for diagnosis of TKA infection.Methods: A PubMed (MEDLINE) search related to TKA infection and PAC was analyzed. The main criteria for selectionwere that the articles were fo...

Background:  Tranexamic acid (TXA) has received extensive attention in management of blood loss in orthopedic surgeries. However, the ideal method of TXA administration is still controversial. This study aims to determine whether intraarticular injection of TXA reduces blood loss after total knee arthroplasty (TKA).   Methods:  Through a retrospective case-control study consecutive TKA patients...

BACKGROUND Malrotation of tibial and femoral components is a potential source of pain following total knee arthroplasty (TKA). This study aimed to 1) compare component rotation in TKA patients with unexplained pain versus a control group with well-functioning TKAs and 2) investigate the relationship between TKA component rotation and pain. METHODS Seventy one patients with unexplained pain af...
