OBJECTIVES To determine whether there is a genetic contribution to knee osteoarthritis (OA) as defined by structural change on plain radiographs. DESIGN Sibling study. Comparison of knee OA prevalence in the community with knee OA prevalence among siblings of index cases with knee OA. SUBJECTS 490 knee OA index cases listed for total knee replacement(More)
OBJECTIVE The prevalence of hip osteoarthritis (OA) increases significantly with age. Although it is not clear whether joint space loss at the hip is a feature of normal aging or a reflection of the OA process, epidemiologic criteria for OA are based on narrowing alone. The aim of this study was to determine whether changes in joint space width occur with(More)
OBJECTIVE To determine whether 2-dimensional measures of femoral head shape and angle are associated with hip osteoarthritis (OA). METHODS We compared cases with symptomatic radiographic hip OA with asymptomatic controls with no radiographic hip OA. On anteroposterior pelvis radiographs, we measured "pistol grip deformity" for each hip (visually(More)
OBJECTIVES To study the influence of genetics on the development of hip osteoarthritis as determined by structural change on plain radiographs. DESIGN Sibling study. SETTING Nottinghamshire, England. PARTICIPANTS 392 index participants with hip osteoarthritis of sufficient severity to warrant total hip replacement, 604 siblings of the index(More)
OBJECTIVE To assess if a coding variant in the gene encoding transient receptor potential cation channel, subfamily V, member 1 (TRPV1) is associated with genetic risk of painful knee osteoarthritis (OA). METHODS The Ile585Val TRPV1 variant encoded by rs8065080 was genotyped in 3270 cases of symptomatic knee OA, 1098 cases of asymptomatic knee OA and 3852(More)
OBJECTIVE To assess the genetic association of pain in patients with knee osteoarthritis (OA) and those with multiple regional pain with the R1150W variant in the α-subunit of the voltage-gated sodium channel Na(V)1.7. METHODS Knee OA patients from 2 UK cohorts (1,411 from the Genetics of Osteoarthritis and Lifestyle study and 267 from the Hertfordshire(More)
OBJECTIVES (1) To develop risk prediction models for knee osteoarthritis (OA) and (2) to estimate the risk reduction that results from modification of potential risk factors. METHOD This was a 12-year retrospective cohort study undertaken in the general population in Nottingham, UK. Baseline risk factors were collected by questionnaire. Incident(More)
The aim of this study was to determine the comparative efficacy and safety of intra-articular (i/a) triamcinolone. hexacetonide (TH) and i/a hyaluronic acid (HA) in inflammatory knee osteoarthritis. A randomized double-blind comparative trail was carried out in a rheumatology outpatient department. There were 63 patients (24 male, 39 female, mean age 70.5(More)
OBJECTIVES To determine cross-sectionally the influence of risk factors on chronic pain following total joint replacement (TJR) of the knee (TKR) or the hip (THR). METHODS Eight hundred sixty post-TKR and 928 post-THR patients were studied. Western Ontario and McMaster Osteoarthritis Index pain scores taken on average 3.2 years postsurgery were correlated(More)
OBJECTIVE To investigate whether radiographic osteoarthritis (OA) is asymmetric and greater on the right side than on the left side in the hands, hips, and knees. METHODS Participants were 489 individuals with posteroanterior hand radiographs from a family study of nodal OA, 1,715 community-derived individuals who had undergone intravenous urography with(More)
