Intra-articular administration specifically involves delivering medication directly into a joint space. This method is commonly used for conditions affecting the joints, such as arthritis, to provide localized treatment and reduce systemic side effects. By injecting directly into the joint, the therapeutic agent can exert its effects more effectively at the site of inflammation or pain, allowing for higher local concentrations and reduced overall dosage needed compared to systemic administration routes.

Other potential options refer to different types of injections that are not related to joint treatment. Injecting into the heart is a specialized procedure typically reserved for specific cardiac interventions, while injections into the eye pertain to ophthalmologic treatments. Muscle injections are used for systemic effects or vaccinations but do not target joint conditions. Thus, the focus of intra-articular administration on joint health makes it the correct choice in this context.
