Abstract
INTRODUCTION: The aim of this study was to characterize national characteristics of patients who have a total knee replacement complicated by popliteal artery injury by incidence and patient demographics. METHODS: All patients with ICD-9 confirmed total knee replacement who had an iatrogenic popliteal artery injury were included from the national in-patient sample from 1998 to 2011. Age, gender and race, procedure type, time to popliteal artery injury, limb outcome, length of stay and hospital inpatient charges were reported. RESULTS: A total of 1,297,369 patients underwent a total knee replacement of which 43 were complicated by popliteal artery injury (0.003%); 93% had osteoarthritis as their primary diagnosis. The mean age was 61.7 ± 12.3 years. In all, 96% of patients had their popliteal injuries detected intra-operatively or on the day of total knee replacement surgery. The majority of these patients either received stent placement (44%) or peripheral bypass (30%) as their treatment modality for popliteal artery injury. There were no amputations or deaths in this cohort. The median hospital charges for this group were $27,570 (2014 USD). CONCLUSION: The national incidence of iatrogenic popliteal artery injury in patients undergoing TKR is 0.003%. There were no amputations in our study population and 96% of patients had their injury detected intra-operative or immediately post-operatively.
