This article outlines the indications and technique of selective denervation for chronic knee pain secondary to neuromata from prior surgery or trauma and describes the results obtained in a series of patients who underwent selective denervation for neuromatous knee. Of the 13 patients in this series, 3 (23%) rated their outcome as excellent, 7 (54%) rated the outcome as good, and 3 (23%) rated the outcome as poor; no patient rated the outcome as worse. Several case reports are included to illustrate the procedure. This technique should be considered an option in select patients with neuromatous knee pain.

This investigation was undertaken to identify the structures torn within the medial retinaculum and localize the injury site anatomically following acute lateral dislocation of the patella in a cadaver model. The patellae of 10 fresh-frozen cadavers were translated laterally 135% of the patella width on a universal testing instrument. Magnetic resonance imaging (MRI) was performed on all specimens prior to testing and immediately following testing. ⋯ The pathology demonstrated in this study may explain the diversity of injury seen clinically. Whereas an avulsion fracture from the patella may represent the medial patellomeniscal ligament, a femoral-sided retinacular tear may represent the medial patellofemoral ligament. This may lead to future refinements of surgical options and anatomic restoration of the damaged structure.
