Quick answer

Mid-substance and insertional Achilles tendinopathy share the need for progressive rehabilitation, but insertional disease requires greater attention to compression at the heel and may involve bony or calcific pathology.

Different range of motion

Mid-substance loading can often progress through a larger dorsiflexion range. Insertional loading may begin on flat ground, avoiding deep dorsiflexion until irritability improves.

Different associated pathology

Insertional disease may include enthesophytes, calcification, bursitis or a prominent calcaneus. Mid-substance disease may show fusiform thickening and focal tendon matrix changes.

Different escalation pathway

When conservative treatment fails, the investigations, injection considerations and operative procedures are not identical. Treatment should therefore be based on a location-specific diagnosis rather than a generic “Achilles tendinitis” label.

Key points

  • Compression is especially relevant at the insertion.
  • Do not copy a mid-substance protocol unchanged into an irritable insertional case.
  • Escalation should remain diagnosis-led.

Frequently Asked Questions

Which type is harder to treat?

Outcomes vary between individuals; the important point is that the treatment strategy should fit the pathology.

Can treatment change as symptoms improve?

Yes. Range, load and activity should progress as capacity and tolerance improve.
