Most patients with lateral epicondylitis will improve over time with a number of nonoperative interventions. Knutsen et al identified risk factors associated with surgical management. The authors are from Washington University in St. Louis and George Washington University.


Patient selection: lateral epicondylitis


Risk factors for surgical management:

(1) worker's compensation claim (odds ratio 8.1)

(2) history of prior injection (odds ratio 5.6)

(3) presence of ipsilateral radial tunnel syndrome (odds ratio 3.1)

(4) history of previous orthopedic surgery (odds ratio 3.2)

(5) duration of symptoms > 12 months (odds ratio 2.5)



• While some patients had a history of orthopedic surgery, none had a history of previous surgery for lateral epicondylitis.
