Ultrasound-Guided Intra-Articular Injection Techniques in Joint Disorders
Summary
Ultrasound-guided intra-articular injection has become a cornerstone in the management of a wide spectrum of joint disorders, offering real-time visualisation of needle trajectory, adjacent neurovascular structures and intra-articular anatomy. By replacing blind or landmark-based approaches, ultrasound guidance enhances accuracy, reduces procedural pain and mitigates complications such as inadvertent cartilage injury or extra-articular deposition of medication. Techniques have been refined across major articulations, including the knee, shoulder, hip, ankle and small joints of the hand and foot, each requiring a bespoke portal and sonoanatomical knowledge. For the knee, familiarisation with recesses such as the suprapatellar pouch, infrapatellar recess and mediopatellar gutter underpins safe needle placement, while in smaller articulations clinicians employ high-frequency transducers to delineate joint capsules and tendinous landmarks. Advances in portable ultrasound devices have extended the reach of guided injections beyond radiology suites to office and field settings. Concurrent innovations in injectate delivery, including sustained-release materials and precise volume control, promise to prolong therapeutic effect and reduce repeat procedures. Collectively, these developments highlight a global shift towards image-guided therapies that prioritise patient comfort, procedural efficiency and targeted relief in joint disease management.
