Diagnostic Value of Shear-Wave Elastography for Patellar Tendinopathy

Diagnostic Value of Shear-Wave Elastography for Patellar Tendinopathy in Female Volleyball and Basketball Athletes

To investigate the accuracy of shear-wave elastography (SWE) in diagnosing patellar tendinopathy in female volleyball and basketball players. In addition, we want to compare different parts of the patellar tendon and investigated the effects of different knee angles.
