BACKGROUND AND PURPOSE Pain sensitization may be one of the reasons for persistent pain after technically successful joint replacement. We analyzed how pain sensitization, as measured by quantitative sensory testing, relates preoperatively to joint function in patients with osteoarthritis (OA) scheduled for joint replacement. PATIENTS AND METHODS We included 50 patients with knee OA and 49 wi...

Runners do not have a greater prevalence of knee osteoarthritis (OA) than nonrunners. The hypothesis that joint loads in running do not cause OA is forwarded. Two mechanisms are proposed: 1) cumulative load, which is surprisingly low in running, is more important for OA risk than peak load, and 2) running conditions cartilage to withstand the mechanical stresses of running.

OBJECTIVE The prevalence of symptomatic knee osteoarthritis (OA) has been increasing over the past several decades in the US, concurrent with an aging population and the growing obesity epidemic. We quantify the impact of these factors on the number of persons with symptomatic knee OA in the early decades of the 21st century. METHODS We calculated the prevalence of clinically diagnosed sympto...

The objective of this study was to determine if disparities in hip and knee replacement surgery exist among osteoarthritis patients with AARP-branded Medicare supplement plan (ie, Medigap) coverage provided by UnitedHealthcare. Patients were selected into the study if they had 1 or more medical claims with a diagnosis of osteoarthritis from July 1, 2006 to June 30, 2007. Logistic regression ana...

Osteoarthritis is prominent among the elderly, with symptoms originating from multiple parts of the body. A cross-sectional study of a nationwide survey was performed to describe the prevalence of and identify factors related to symptomatic hip, knee, and spine osteoarthritis.This cross-sectional study collected data from the Fifth Korean National Health and Nutrition Examination Survey (KNHANE...

BACKGROUND Total hip arthroplasty (THA) in patients with a history of Slipped Capital Femoral Epiphysis (SCFE), is typically indicated to address the consequent deformity of the proximal femur and/or acetabulum. It can be a challenging procedure for the orthopaedic surgeon. Previous studies have focused on prevention of osteoarthritis post-SCFE. However, there is a paucity of data on the outcom...

BACKGROUND We examined the effect of adult weight change on risk for total hip replacement resulting from primary osteoarthritis, using a prospective study design. METHODS We linked data on body mass index and body weight from 3 screening surveys in 3 Norwegian counties (mean ages at screenings 34, 43, and 47 y; n = 38,868) with follow-up data on total hip replacement (n = 572). Mean age at t...

ABSTRACT The present study aimed to investigate the clinical results of modified Codivilla–Hey Groves–Colonna capsular arthroplasty in treatment young patients with developmental dislocation hip. We retrospectively evaluated 90 (92 hips) who underwent from June 2012 2021. Hips were using hip Harris score (mHHS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) 12-item Inte...

BACKGROUND Acetabular dysplasia (AD) is the main cause of hip osteoarthritis in Japan. A simple method to evaluate acetabular dysplasia would be helpful for early treatment or prevention of hip osteoarthritis. Acetabular dysplasia is reported to be associated with pathological transverse growth of the pelvis, indicating that the distance between the 2 anterior superior iliac spines might be use...

INTRODUCTION The rate of osteoarthritis of the hip secondary to slipped capital femoral epiphysis (SCFE) is a subject of debate, and its frequency is underestimated in particular because of subclinical forms that may not be diagnosed during childhood. HYPOTHESIS The frequency of radiographic anomalies subsequent to SCFE in adults requiring hip arthroplasty is higher than that reported in rece...
