This meta-analysis evaluated preoperative aspiration culture for diagnosing prosthetic joint infection (PJI) in total hip arthroplasty (THA) and total knee arthroplasty (TKA). The pooled sensitivity and specificity were 0.72 (95% confidence interval, 0.65 to 0.78) and 0.95 (0.93 to 0.97), respectively. Subgroup analyses revealed nonsignificant worse diagnostic performance for THA than for TKA (...

Periprosthetic joint infection is a devastating complication after total joint replacement. Prevention is mandatory and systemic antibiotic prophylaxis is nowadays a recognized cornerstone. Further addition of local antibiotics eluting from bone cement is a real possibility but its routine use is controversial. Pros and cons of its routine use in primary and revision total joint arthroplasty wi...

While the value of national arthroplasty registries (NAR) for quality improvement in total hip arthroplasty (THA) has already been widely reported, some methodological limitations associated with observational epidemiological studies that may interfere with the assessment of safety and efficacy of prosthetic implants have recently been described in the literature. Among the main limitations of ...

AIM To identify patient and surgical risk factors that are associated with periprosthetic joint infection (PJI), especially whether obesity is a risk factor following total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS New Zealand Surgical Site Infection Improvement Programme data was analysed using deep infection within 90 days of the index procedure as the outcome. This ...

CONTEXT While patient-reported outcomes (PROs) have long been used for research, recent technology advancements make it easier to collect patient feedback and use it for patient care. Despite the promise and appeal of PROs, substantial barriers to widespread adoption remain-including challenges in interpreting privacy regulations, educating patients and physicians about the power that PRO colle...

Background and purpose - There are concerns that mental health (MH) may influence outcomes of total knee arthroplasty (TKA) or total hip arthroplasty (THA). We examined effects of poor MH before surgery on long-term outcomes of osteoarthritis-related TKA or THA in women. Patients and methods - The data were from 9,737 middle-aged participants (47-52 years) and 9,292 older participants (73-78 ye...

AIM Controversy surrounds prevention, detection and clinical relevance of pulmonary embolism (PE) following arthroplasty in orthopaedic patients. We aimed to review the rates of computer tomography pulmonary angiography (CTPA), PE and fatal PE following total joint replacement. METHOD Mixed retrospective/prospective review of CTPA requests and PE incidence amongst patients undergoing primary ...

Background: Quadriceps avoidance is a reflex deficit disorder of quadriceps activation after total knee arthroplasty (TKA) that can lead to abnormal gait kinematics. It patient apprehension due pain, prevent induces deforming forces at the joint. Aim: To describe frequency ‘quadriceps avoidance’ among patients arthroplasty. Study Design: Descriptive case series. Methodology: The study sample si...

Numbers of patients are suffering from aseptic loosening after total hip replacement, which can need further revision surgery. Particle-induced osteolysis has been considered as a major cause of aseptic loosening after hip joint replacement. This is a prospective study, and there are 82 patients of unilateral osseous arthritis and 10 normal physical examination people in our hospital for this s...
