To our knowledge, this is the first study that has utilized a validated algorithm to identify TKA recipients with RA, thereby increasing the validity of our findings, and aiding patientphysician decision-making around joint replacement in patients with RA. Further research is required to elucidate potential explanations for the higher rates of infection in RA versus OA, including the use of biologic agents. 261 MORE PROMINENT INFLAMMATORY FEATURES IN KNEE OSTEOARTHRITIS IN THE PRESENCE OF CONCOMITANT HAND OSTEOARTHRITIS C. Orellana, N. Navarro, J. Calvet, M. Garcia-Manrique, J. Gratacos, M. Larrosa. CSiU Parc Tauli. Hosp. de Sabadell, Sabadell, Spain Background: In recent years it has been recognized the existence of a link between hand osteoarthritis and systemic inflammation. On the other hand, a significant proportion of patients with knee osteoarthritis show local clinically evident inflammatory features such as synovial effusion and synovial hypertrophy. Purpose: To evaluate if patients with knee osteoarthritis show more inflammatory signs as measured by ultrasound when hand osteoarthritis is concomitantly present. Methods: Patients aged 50 years or more with symptomatic osteoarthritis of the knee and joint effusion, Kellgren-Lawrence II-III. Demographics, BMI, disease duration, pain assessed by VAS (0-100 mm) and algofuncional Lequesne index were assessed. Knee ultrasound was performed evaluating and measuring the presence of effusion and synovial hypertrophy (defined as > 4 mm synovial thickening) at the suprapatellar midline. Results: In a cross-sectional study we analyzed 50 patients, F/M 39/11, age 61.8 10.1 years, disease duration 50.8 6.3 months, BMI 28 1.4 kg/cm2. Ten patients (20%) had concomitant hand osteoarthritis. There were no significant differences in age, disease duration, BMI or radiological grade between patients with knee and hand osteoarthritis compared with those with only knee osteoarthritis. On ultrasound examination patients with concomitant hand osteoarthritis showed a clear trend to have a more prominent joint effusion (7.39 3 vs. 6.7 2.8 mm) and synovial hypertrophy (3.6 2.6 vs. 2.7 1.8 mm), although not statistically differences were found. Patients with concomitant hand osteoarthritis also had a non-significant trend to experience greater knee pain (VAS 70.3 12.5 vs. 61 18.5 mm) and Lesquesne index scores (11.4 3.3 vs. 9.8 2.9). Conclusions: Although results were not statistically significant probably in relation to small size sample, in this study the presence of hand osteoarthritis appeared to be associated with greater inflammatory features in patients with symptomatic knee osteoarthritis. 262 NETWORKING TO CAPTURE PATIENT-REPORTED OUTCOMES DURING ROUTINE ORTHOPAEDIC CARE ACROSS TWO DISTINCT INSTITUTIONS R.
