Session Title: Osteoarthritis - Clinical Aspects
Session Type: Abstract Submissions (ACR)
The purpose of this study was to investigate the prevalence of periarticular lesions detected by magnetic resonance imaging (MRI) and its association with knee pain and radiographic knee osteoarthritis (OA) in community residents in Korea.
Participants (n=357) were randomly chosen regardless of knee OA or knee pain from the population-based Hallym Aging Study. Demographic data and knee pain data including the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index were obtained by questionnaire. We assessed peiarticular lesions on 1.5-tesla MRI in the more symptomatic knee. Periarticular lesions included prepatellar or infrapatellar bursitis, anserine bursitis, Baker’s cyst, and tibiofibular cyst. The association between each lesion and knee pain was examined by logistic regression analysis after adjustment of age, gender, body mass index, radiographic knee OA and other periarticular lesions.
Radiographic knee OA was present in 34.5% of subjects. The most prevalent lesion was Baker’s cyst (27.5%), followed by tibiofibular cyst (9.5%). Anserine bursitis was significantly associated with the presence of knee OA (OR 4.45, 95% CI [1.45-13.61]). Anserine bursitis among the subjects with OA was more common in the subjects with knee pain (21.8%) than in those without pain (7.1%). Anserine bursitis and Baker’s cyst were significantly associated with knee pain (OR 3.47, 95% CI [1.18-10.21] and OR 2.03, 95% CI [1.19-3.45], respectively). Other periarticular lesions were not associated with knee pain or the presence of knee OA.
Incidental periarticular lesions on MRI of the knee are common in the middle- aged and elderly community residents in Korea. Anserine bursitis is related with knee pain and knee OA. Baker’s cyst is associated with knee pain.
