The joint to be aspirated should be resting on a hospital bed, table, or other stable, immobile structure. The patient should always be lying or sitting down and should be at a comfortable height for the physician. For details on how to position the patient for specific joint aspirations, see Approaches to Specific Joints in the Technique section. These positions are designed so that the joint capsule bulges forward towards your needle.
