Vakharia RM, et al. - This study was attempted to assess if chronic obstructive pulmonary disease (COPD) individuals undergoing primary total knee arthroplasty (TKA) have higher rates of in-hospital lengths of stay (LOS), readmissions, VTEs; and costs of care. Researchers distinguished COPD individuals who underwent primary TKA and matched to controls in a 1:5 ratio by age, gender, and medical comorbidities. They excluded those individuals who have a history of VTEs or hypercoagulable states. A correlation was found between COPD and higher rates of developing VTEs following primary TKA after adjusting for confounding variables. The research can be applied by orthopaedic surgeons to adequately counsel and educate these individuals of the potential complications which may arise following their TKA.
