Epicondylitis is one of the most common elbow problems in adults, occurring both laterally and medially. Medial epicondylitis of the elbow, commonly referred to as ‘golfer’s elbow,’ is characterized by pathologic changes to the musculotendonous origin at the medial epicondyle.
There exists a paucity of literature regarding medial epicondylitis, likely due to its infrequent incidence of only 9.8% to 20% of all epicondylitis diagnoses. Originally thought to be an inflammatory process, as the name suggests, epicondylitis has been shown histologically to result from tendonous microtearing, followed by an incomplete reparative response. Consequently, some physicians prefer the more accurate term, tendonosis, when describing elbow epicondylitis.
