BACKGROUND Tobacco smoking is a risk factor for several adverse post-operative outcomes. We aimed to compare the rates of complications in current tobacco users and non-users who underwent primary total hip arthroplasty (THA) or total knee arthroplasty (TKA). METHODS All patients who underwent primary THA or TKA at the Mayo Clinic from 2010-2013 were included in the study. Current tobacco use...

BACKGROUND Leg length discrepancies following total hip arthroplasty (THA) may necessitate subsequent interventions, from heel lifts to revision surgery. Current intraoperative methods of determining leg length are either inaccurate or expensive and invasive. OBJECTIVE The objective of the current study was to investigate the ability of a novel, intraoperative smart tool (Intellijoint HIP®, I...

There are some plants can replaced grass among cover plants. Cover plants are obvious solution of problem in these places that the most important plant is Frankinia and Lisimakia etc. The aim of this study is to use organic wastes, biological fertilizers and moisture super absorbents in the growth media of Frankinia to increase water holding capacity, delay in permane...

BACKGROUND Aseptic implant loosening and periprosthetic bone loss are major problems after total hip arthroplasty (THA). We present an in vivo method of computed tomography (CT) assisted osteodensitometry after THA that differentiates between cortical and cancellous bone density (BD) and area around the femoral component. METHOD Cortical and cancellous periprosthetic femoral BD (mg CaHA/mL), ...

RATIONALE Inflammatory pseudotumor has been commonly reported in patients undergoing total hip arthroplasty (THA). PATIENT CONCERNS We reported a patient who had a massive intra-pelvic pseudotumour and acetabular bone defect underwent two-stage revision THA. DIAGNOSES A new surgical strategy for pseudotumor after THA is performed. INTERVENTIONS Thorough debridement intra-pelvic pseudotumo...

Due to the increased number of revision total hip arthroplasties (THAs) to correct pain secondary to fretting from modular hip stems, this study was conducted in an effort to correlate objective findings of serum cobalt (Co) levels, serum chromium (Cr) levels, and/or reactive tissue seen on metal artifact reduction sequence (MARS) magnetic resonance imaging (MRI) with a patient's need for revis...

BACKGROUND Both minimally invasive surgery (MIS) and computer-assisted surgery (CAS) for total hip arthroplasty (THA) have gained popularity in recent years. We conducted a qualitative and systematic review to assess the effectiveness of MIS, CAS and computer-assisted MIS for THA. METHODS An extensive computerised literature search of PubMed, Medline, Embase and OVIDSP was conducted. Both ran...

OBJECTIVE To assess the efficacy of a single intra-articular injection of triamcinolone hexacetonide (THA) in knee osteoarthritis (OA) and examine factors which may relate to treatment efficacy. METHODS Eighty four patients with clinical and radiographic evidence of knee OA were recruited and randomly allocated to receive either THA (20 mg in 1 ml) or placebo (0.9% normal saline, 1 ml). Follo...

BACKGROUND Young patients with osteonecrosis (ON) treated with THA often have suboptimal function and radiographic failure with eventual revision. Resurfacing may be an option because of potentially increased functionality and decreased radiographic failure, although neither has been confirmed in the literature. QUESTIONS/PURPOSES We therefore compared the clinical scores and radiographic fai...

Infection rates in primary (first-time) major joint arthroplasty continue to be a significant issue. The effect of antibiotic and antiseptic prophylaxis on outcomes for this type of surgery has not been adequately reviewed. A systematic search of the main databases for randomized controlled trials (RCTs) evaluating antibiotics and antiseptics was conducted to evaluate the predetermined endpoint...
