Nonoperative treatment of insertional Achilles tendinopathy: a systematic review.

Insertional Achilles tendinopathy, pain and thickening where the tendon attaches to the heel bone, is notoriously stubborn to treat, and clinicians have long lacked clear guidance on which nonoperative approach works best. This systematic review pulled together studies testing eccentric exercise, extracorporeal shockwave therapy, injections, and combinations of these, then compared outcomes using pain scales and function questionnaires. Across the pooled evidence, shockwave therapy alone or combined with eccentric exercise appeared to come out ahead of other nonoperative options. The finding is worth noting because insertional tendinopathy behaves differently than tendinopathy higher up the Achilles, and treatments that help one don't always help the other.

The main caveat is that the review draws on a mix of study types and treatment groups of varying quality, so the conclusion reflects a pattern across the literature rather than a single definitive trial answer.

If you've dealt with pain right where your Achilles tendon meets your heel bone, you know how frustrating it can be to find something that actually helps. This condition, called insertional Achilles tendinopathy, is different from Achilles pain higher up the leg, and researchers wanted to know which non-surgical treatments actually work for this specific spot. After reviewing 23 studies that tested things like eccentric exercises, shockwave therapy, and injections, the researchers found that shockwave therapy, especially when paired with eccentric exercises, tended to show the best results among the options studied.

That's a useful signal, but it comes with an important caveat: the underlying studies varied in size and quality, and this review is a summary of existing research rather than one large, tightly controlled trial. So while the pattern favoring shockwave therapy is notable, it shouldn't be read as a settled answer, just the best available evidence so far for a condition that has been genuinely hard to treat.

This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.

This systematic review searched PubMed, Embase, and Web of Science through October 2020 and identified 23 studies comprising 35 treatment groups addressing nonoperative management specifically for insertional Achilles tendinopathy, distinct from midportion disease. Interventions included eccentric loading protocols, extracorporeal shockwave therapy (ESWT), various injections, and combined approaches, with outcomes assessed via VAS, the VISA-A questionnaire, AOFAS scores, and satisfaction rates. Across the synthesized evidence, ESWT alone or combined with eccentric exercise was favored over other nonoperative modalities.

However, the abstract does not report pooled effect sizes, confidence intervals, or a formal meta-analysis, and study quality assessment was performed but specific risk-of-bias findings or heterogeneity statistics were not detailed. Given the heterogeneous mix of study designs and treatment groups typical of this literature, the conclusion should be interpreted as a directional signal from the best currently available evidence rather than a high-certainty finding. Clinicians should note that insertional tendinopathy has historically shown different treatment responsiveness than midportion Achilles tendinopathy, particularly regarding eccentric loading alone, which underscores why this condition-specific review is relevant despite its evidentiary limitations.
