Achilles Tendinitis Tendinosis Wheeless

Description: while there are many causes of posterior ankle pain, there are two distinct conditions which may affect the Achilles tendon: - tendinitis and tendinosis, each having a distinct prognosis; - Tendinitis / Tendinosis: - in some cases, there will be a peritendinous inflammation which does not generally progress to degenerative tendinosis (nor rupture); - in other situations, there will be clinical inflammation, but objective pathologic evidence for cellular inflammation is lacking, and in these conditions the term tendinosis is more appropriate;
