Retraction can be treated medically, by stretching, or surgically, by lengthening the muscles. Gastrocnemius retraction is difficult to measure, but tests such as the Ankle Dorsiflexion Index (ADI) provide a more accurate assessment.\n\nKnowing the prevalence of this retraction in patients suffering from plantar fasciitis would enable us to improve diagnostic criteria and better target treatments. Surgical lengthening of the gastrocnemius, particularly by tenotomy, is effective in cases of chronic plantar fasciitis, even without apparent muscle retraction.",[27],"Plantar Fasciitis","NOT_YET_RECRUITING","2025-07-01",{"date":31,"type":32},"2025-07-11","ACTUAL",{"date":34,"type":21},"2025-09-01",{"date":36,"type":21},"2029-03-01",{"name":38,"class":39},"Clinique Saint Charles","OTHER",""]
