title: Ultrasonographic detection of the patellar plica in the knee.
abstract: In 39 knees of 38 patients, an ultrasonographic investigation of the patellofemoral space was performed to detect a plica synovialis. By arthroscopic control, we found a sensitivity for the ultrasonographic method of 92% and a specificity of 73%. The method, materials, and results are discussed in this paper.
