Weight Loss Is Associated with Structure Modification in Subjects with Radiographic Osteoarthritis of the Knee: Data From the Osteoarthritis Initiative
Background/Purpose: Obesity is a risk factor for the development and progression of knee osteoarthritis (OA) and weight loss is recommended as part of the management…Abstract Number: 1120 • 2012 ACR/ARHP Annual Meeting
Cartilage Volume Loss Occurs in Most Older Adults and the Rate of Loss Increases with Age
Background/Purpose: Radiographic data suggests knee osteoarthritis is a relatively static disease even over the long term. It is uncertain how much this is influenced by…Abstract Number: 1090 • 2012 ACR/ARHP Annual Meeting
A Comparison of Patient-Reported and Measured Range of Motion in a Cohort of Total Knee Replacement Patients
Background/Purpose: Range of motion (ROM) is an important component of the assessment of total knee replacement (TKR) outcome. Traditionally, ROM is measured by a clinician…Abstract Number: 266 • 2012 ACR/ARHP Annual Meeting
Knee Joint Stabilization Therapy in Patients with Osteoarthritis of the Knee: A Randomized, Controlled Trial
Background/Purpose: Patients with knee osteoarthritis (OA) and instability of the knee joint may not benefit optimally from regular strengthening training. Therefore, we evaluated the effectiveness of a newly…Abstract Number: 2537 • 2012 ACR/ARHP Annual Meeting
Cross-Sectional and Longitudinal Associations Between Circulating Leptin and Knee Cartilage Thickness in Older Adults
Background/Purpose: To investigate cross-sectional and longitudinal associations between serum leptin levels and knee cartilage thickness in older adults. Methods: A prospective cohort of 163 randomly…Abstract Number: 1123 • 2012 ACR/ARHP Annual Meeting
Comparison of Anatomic Knee Alignment On Physical Examination and Radiographs
Background/Purpose: Severity of knee malalignment is a risk factor for osteoarthritis (OA) progression. Currently the hip-knee-angle (mechanical axis), assessed on a full-limb radiograph, is the…Abstract Number: 1093 • 2012 ACR/ARHP Annual Meeting
Obesity Is Not a Risk Factor for Poor Pain and Function Two Years After Total Knee Replacement
Background/Purpose: Almost 90% of referring physicians think obesity increases the likelihood of poor outcomes after total knee replacement (TKR). However, current data are conflicting. The…Abstract Number: 237 • 2012 ACR/ARHP Annual Meeting
Association Between Pain Threshold, Symptoms and Radiographic Knee and Hip Osteoarthritis: The Johnston County Osteoarthritis Project
Background/Purpose: Little is known of the association between pain threshold and knee/hip symptoms as well as radiographic knee/hip osteoarthritis (rOA). These analyses: 1) determined the…Abstract Number: 2538 • 2012 ACR/ARHP Annual Meeting
The Association of Fat Mass and Skeletal Muscle Mass with Clinical and Structural Knee Osteoarthritis: The Netherlands Epidemiology of Obesity Study
Background/Purpose: Body mass index (BMI) is an important risk factor for knee osteoarthritis (OA), but BMI depends only upon height and weight and gives no…Abstract Number: 1124 • 2012 ACR/ARHP Annual Meeting
Total Knee Replacement As an Osteoarthritis Study Outcome: Predictors Derived From Long-Term Observation Following a Randomized Clinical Trial
Background/Purpose: Using data from a 4-year follow-up of knee OA patients who formerly received treatment with chondroitin sulfate (CS) within a 6-month clinical trial, we…Abstract Number: 1029 • 2012 ACR/ARHP Annual Meeting
Frequency of Mediopatellar Plica in Persons with Chronic Knee Pain and Its Cross-Sectional Association with Patellofemoral Cartilage Damage and Bone Marrow Lesions: Data From the Joints On Glucosamine Study
Background/Purpose: Osteoarthritis (OA) commonly occurs in the patellofemoral joint (PFJ) and knee pain in subjects with knee OA often emanates from the PFJ rather than…Abstract Number: 238 • 2012 ACR/ARHP Annual Meeting
Inevitable Deterioration? Trajectories and Risk Profiles of Pain in Patients with Radiographic, Symptomatic Knee Osteoarthritis
Background/Purpose: Knee pain is the primary reason that patients with OA seek medical care. The goal of this study is to describe pain trajectory over…Abstract Number: 2512 • 2012 ACR/ARHP Annual Meeting
Changes in Bone Marrow Lesion Volume Relate to Changes in Knee Pain. Data From the Osteoarthritis Initiative
Background/Purpose: Changes in bone marrow lesions (BMLs), common magnetic resonance (MR) imaging findings in osteoarthritis (OA), are predictive of OA progression. However, it is unclear…Abstract Number: 1125 • 2012 ACR/ARHP Annual Meeting
Three Trajectories of Activity Limitations in Early Symptomatic Knee Osteoarthritis: A 5-Year Follow-up Study
Background/Purpose: Knee osteoarthritis (OA) is one of the leading causes of activity limitations among older adults. The course of activity limitations is highly variable; some…Abstract Number: 1030 • 2012 ACR/ARHP Annual Meeting
Frequency and Fluctuation of Susceptibility Artifacts in the Tibio-Femoral Joint Space in Painful Knees On 3T MRI and Association with Meniscal Tears, Radiographic Joint Space Narrowing and Calcifications
Background/Purpose: Linear or punctate hypointensities are commonly seen on gradient echo (GRE) sequences in the tibiofemoral joint (TFJ) space of osteoarthritic joints. These magnetic susceptibility…
