This 1979 landmark case series by Nirschl and Pettrone defines the pathology of lateral epicondylitis and presents the operative technique that has shaped surgical management ever since. Of 1,213 total cases seen over nearly 6 years, 88 elbows in 82 patients failed conservative care and underwent surgery. The study characterizes the underlying lesion, describes the surgical approach, and reports outcomes at mean 25-month follow-up.
When a patient fails 6+ months of conservative care for lateral epicondylitis, this paper tells you exactly what you will find at surgery and what to do about it.
Before Nirschl, the pathology of tennis elbow was disputed — bursitis, nerve entrapment, periostitis, and orbicular ligament inflammation were all proposed. Prior operations released the extensor aponeurosis (Bosworth, Hohmann) without ever seeing the true lesion, producing inconsistent results.
The operative principle here is precise: retract the ECRL, identify the angiofibroblastic hyperplasia at the ECRB origin, excise it sharply (typically 75% of the proximal tendon), decorticate the anterior lateral condyle to stimulate vascularity, and repair the ECRL-aponeurosis interface. No direct ECRB repair is needed. The tendon does not retract due to fascial adherence.
Tell your patient: pain relief by 2-3 months, full strength by 4 months, back to tennis by 6 months. Psychosocial screening matters. Both failures in this series had significant psychiatric comorbidities, a point Nirschl explicitly emphasizes.
