MSK Ultrasound has become extremely popular for not just diagnostic imaging, but now is being routinely used for needle guidance. Various nerve blocks, intra-articular injections, trigger point and muscular injections are now being done under ultrasound guidance.
"They found that approximately one third of knee and ankle injections were extra-articular, only half of the wrist injections were definitely intra-articular, with even less accuracy reported for shoulder injections. Remarkably, even the ability to aspirate synovial fluid was not a perfect predictor of intra-articular placement of steroid injections with almost half of extra-articular injections having been associated with successful aspiration of synovial fluid. Experience beyond advanced trainee/registrar level did not appear to influence the accuracy of injection placement."

Corticosteroid injection in the joints of patients with inflammatory arthritis results in significant alleviation of symptoms and improvement in functional status. Ultrasound-guided injections are significantly more accurate than clinical examination (CE)-guided injections.
Ultrasound-guided injections were accurate in 83% of patients, compared with 66% of patients who had CE-guided injections. There was a trend toward increased accuracy with US-guided injections for all joints, particularly the shoulder, elbow, and ankle. The greater accuracy of US-guided injections held true regardless of the physician’s level of experience.The Journal of Musculoskeletal Medicine. Vol. 27 No. 9

They significantly reduce procedural pain, reduce pain scores at outcome, increase responder rates, and reduce non-responder rates.The authors suggested that their findings strongly support the use of sonography for intra-articular injections in outpatient musculoskeletal practices and that research is needed to address the effects of such procedures on long-term outcomes.
