Leave it alone Achilles Tendinopathy Definition: Tendinosis and/or peritendonitis Achilles Tendinopathy Etiology: - Inelasticity - Hypovascularity - Overuse / Age - Fluoroquinolones - Constrictive shoes - Inflammatory arthropathy Achilles Tendonitis/osis Achilles Tendonitis/osis Peritendinitis: inflammation involving peritendinous structures. In acute setting, symptoms typically last less than 2 weeks; in Insertional disease Non-insertional subacute setting, symptoms last 2 to 6 weeks; with chronic disease peritendinitis, symptoms are present 6 weeks or longer. Chronic peritendinitis may be associated with tendinosis. Peritendinitis with tendinosis: inflammatory process involving peritendinous structures along with degeneration of tendon. Tendinosis: typically an asymptomatic degeneration of tendon without concomitant inflammation caused by accumulated microtrauma, aging, or both. With tendinosis an interstitial rupture, partial rupture, or acute rupture may develop Physical exam . Physical exam . Thompson test: Take home . No rupture Ruptured Imaging . Achilles Tendinopathy Clinical presentation: - posterior heel pain and swelling - ankle stiffness - posterior prominence Differential: Acute rupture Posterior tibial tendon pathology Tarsal tunnel syndrome Posterior ankle impingement (os trigonum, etc.) Achilles Tendinopathy: Non-operative Treatment Biomechanical measures - Eccentric stretching exercises The term “pump bump” is used - Immobilization - Night splint loosely but generally applies to a Haglund’s process or Local measures swelling associated with - Shoewear modification/stretching insertional Achilles - Gel sleeve tendonitis Biochemical measures -NSAIDs Non-operative Treatment -Eccentric stretching -Night splint -Heel lift (1/4”) Surgical Treatment .
