Bone bruise in magnetic resonance imaging strongly correlates with the production of joint effusion and with knee osteoarthritis.

Background: The findings of magnetic resonance imaging (MRI) have not been studied systematically in patients with osteoarthritis (OA). The objective here was to compare MRI findings with radiological findings in patients with knee pain and to identify factors that influence the progression of OA of the knee.

Methods: Of 212 patients with knee pain and MRI of the knee joint, 161 patients were selected for the study after exclusion of cases of trauma and other arthritides.

Validation of a Japanese version of the Scoliosis Research Society-22 Patient Questionnaire among idiopathic scoliosis patients in Japan.

Study Design: A cross-sectional observational study to determine the response distribution, internal consistency, and construct, concurrent, and discriminative validities of The Scoliosis Research Society-22 (SRS-22) Patient Questionnaire translated into Japanese as compared with the other language versions.

Objective: To validate the Japanese version of SRS22.

Summary Of Background Data: The SRS-22 was translated into several languages but yet not into Japanese.
