The use of a standard-length conical tapered stem in hip revision arthroplasty to address Paprosky type I-II femoral defects: a prospective study of 87 patients.

Introduction: Low-grade femoral defects in revision total hip arthroplasty (rTHA) might be preferably treated with a primary implant. Almost no previous study reported the use of standard-length conical tapered (SLCT) stems in these cases. We analyzed a series of cases using a SLCT stem in rTHA with Paprosky type I-II femoral defects.

Severe Obesity Increases Risk of Infection After Revision Total Hip Arthroplasty.

Background: The increasing prevalence of obesity has resulted in an increased number of revision total hip arthroplasties (rTHAs) performed in patients with a high body mass index (BMI). The aim of this study is to evaluate whether obesity negatively affects (1) complication rate, (2) reoperation and revision rate, and (3) patient-reported outcome in rTHA.

Methods: In this registry-based study, we prospectively followed 444 rTHAs (cup: n = 265, stem: n = 57, both: n = 122) performed in a specialized high-volume orthopedic center between 2013 and 2015.

Development of the "Treatment beliefs in knee and hip OsteoArthritis (TOA)" questionnaire.

Background: Use of conservative treatment modalities in osteoarthritis (OA) is suboptimal, which appears to be partly due to patients' beliefs about treatments. The aim of this study was to develop a research instrument assessing patients' beliefs about various treatment modalities of hip and knee OA: the 'Treatment beliefs in OA (TOA) questionnaire'.

Methods: The item pool that was retrieved from interviews with patients and healthcare providers comprised beliefs regarding five treatment modalities: physical activity, pain medication, physiotherapy, injections and arthroplasty.

Treatment Beliefs Underlying Intended Treatment Choices in Knee and Hip Osteoarthritis.

Purpose: Patients' beliefs about treatment modalities for knee and hip osteoarthritis (OA) will underlie their treatment choices. Based on the Theory of Planned Behavior, it is hypothesized that patients' beliefs, subjective norm, and perceived behavioral control guide their treatment choices. Also, symptom severity and one's inherent tendency to approach or avoid situations are assumed to play a role.

Hierarchical structure and importance of patients' reasons for treatment choices in knee and hip osteoarthritis: a concept mapping study.

Objectives: To improve patients' use of conservative treatment options of hip and knee OA, in-depth understanding of reasons underlying patients' treatment choices is required. The current study adopted a concept mapping method to thematically structure and prioritize reasons for treatment choice in knee and hip OA from a patients' perspective.

Methods: Multiple reasons for treatment choices were previously identified using in-depth interviews.

Reasons for Treatment Choices in Knee and Hip Osteoarthritis: A Qualitative Study.

Objective: Conservative treatment modalities in osteoarthritis (OA) of the hip or knee are underused, whereas the demand for surgery is rising substantially. To improve the use of conservative treatment modalities, a more in-depth understanding of the reasons for patients' treatment choices is required. This study identifies the reasons for choice of treatment in patients with hip or knee OA.

Early failures in large head metal-on-metal total hip arthroplasty.

Concerns have recently been raised about large head metal-on-metal total hip arthroplasties (LDH THA). Metal ion release due to wear may cause osteolysis, pseudotumours and necrosis. In addition, fixation of certain acetabular components is thought to be suboptimal.

Identification of orthopaedic infections using broad-range polymerase chain reaction and reverse line blot hybridization.

Background: Culture remains the gold standard in the diagnosis of bacterial infection, but molecular biological techniques have yielded promising results. In this study, we validated a combined polymerase chain reaction and reverse line blot hybridization protocol for identifying musculoskeletal infections.

Methods: Samples were obtained from seventy-six patients undergoing orthopaedic surgery for various aseptic and septic indications.
