The aim of the study was to determine whether cervical spine degenerative diseases have a role in complications following TKA within 2 years. Methods  Data were collected from the Humana insurance database using the PearlDiver Patient Records Database from 2007–2017. Patients who had a primary TKA were identified using Current Procedural Terminology (CPT) code 27,447, and patients with degenerative cervical disease were identified using CPT and International Classification of Diseases (ICD) codes.
