ABSTRACT Introduction: In this we study identified potential risk factors for post−total knee arthroplasty (TKA) nerve injury, a catastrophic complication with a reported incidence of 0.3%−1.3%. Methods: Patients who developed post‐TKA nerve injury from 1998 to 2013 were identified, and each was matched with 2 controls. A multivariable logistic regression model was built to calculate odds ratios (ORs). Results: Sixty‐five nerve injury cases were identified in 39,990 TKAs (0.16%). Females (OR 3.28, P = 0.003) and patients with history of lumbar pathology (OR 6.12, P = 0.026) were associated with increased risk of nerve injury. Tourniquet pressure
