Background
Whether injecting the ankle joint from the inside-front (anteromedial) or outside-front (anterolateral) approach gives a better chance of the needle actually reaching inside the joint, in a controlled cadaver study.
Rationale
Ankle injections are commonly used for both diagnosis and treatment of ankle pain. If the injectate doesn’t actually enter the joint, the diagnostic information is wrong and any therapeutic effect is uncertain. Knowing the most reliable landmark approach matters.
Results
Across 76 cadaver ankles: anteromedial succeeded 78% of the time, anterolateral 86%. The difference wasn’t statistically significant. Overall success was 82%. The clinical implication: a meaningful minority of landmark-only ankle injections miss the joint, even with experienced operators. Adding ultrasound or fluoroscopy improves accuracy.
Implications
If you’re having a diagnostic ankle injection — one where the result will be used to make a treatment decision — ask whether it can be done under ultrasound or X-ray guidance. The added accuracy is worth it.
