Achilles Tendinopathy

Understanding Achilles Tendinopathy

Also known as: Achilles Tendinosis, Achilles Tendinitis, Mid-Portion or Insertional Achilles Tendinopathy The Achilles tendon — the thickest and strongest tendon in the body — connects your calf muscles to the heel bone. With repetitive overload, the tendon's repair capacity falls behind its loading demands, producing disorganized collagen, thickening, and pain. Mid-portion tendinopathy occurs two to six centimeters above the heel; insertional tendinopathy sits right at the bone attachment and is managed slightly differently because the loading mechanics differ. Both respond to the same core principle: progressive loading is medicine.

Stiffness and tenderness in the Achilles first thing in the morning or after sitting — "warming up" as you get moving — with an aching return after activity, is the classic pattern. The tendon may feel thickened or nodular. Middle-aged recreational athletes, runners ramping up training, and people with tight calves are most affected. The backbone of treatment is loading.

We guide you through an eccentric heel-drop program — Alfredson protocol for mid-portion, modified for insertional cases — which reorganizes and strengthens the tendon over time. IASTM and ART reduce adhesions. Class IV laser and shockwave therapy — particularly for chronic, stubborn cases — support healing. Ankle and subtalar mobilization restores normal joint play.

We coach load management, heel lift use, and footwear selection. Most patients improve substantially within eight to twelve weeks. A positive Thompson test (squeezing the calf doesn't produce foot movement) or a sudden pop with calf pain warrants immediate rupture evaluation. We may recommend: Graston/IASTM, ART, extremity adjustments, mobilization, Class IV laser, shockwave therapy, eccentric loading protocol, orthotics Seek immediate care if: You felt a sudden pop or "kick in the calf" with weakness pushing off — this may indicate Achilles rupture requiring urgent evaluation.
