Most knee structures can be accurately targeted using ultrasound guidance. These structures are usually superficial, and the overlying soft tissues are mobile and compressible, facilitating excellent visualization with a high-frequency linear array transducer. ⋯ Studies of ultrasonography-guided knee procedures have consistently shown high accuracy, and its use is particularly beneficial for obese patients, diagnostic injection specificity, safety, and precise targeting of pathology. More studies are needed to assess the clinical efficacy and cost-effectiveness of ultrasonography-guided knee procedures.
