INTRODUCTION: Total Knee Arthroplasty (TKA) is an important treatment for @entity625 ( @entity625 ), but evidence on outcomes is sparse. The purpose of this study was to evaluate the impact of @entity625 versus @entity571 ( @entity571 ) on postoperative outcomes after TKA. METHODS: We queried the entire Medicare database from 2005 to 2012. International Classification of Diseases, 9th revision and Current Procedural Terminology codes were used to identify the procedure, indication, and complications. @entity1 with minimum two-years follow-up were selected. Odds ratios (ORs), confidence intervals, and p-values (p) were calculated. RESULTS: For @entity625 , 3509 @entity1 had TKA. For @entity571 , 257,611 @entity1 with TKA served as controls. The average Charlson Comorbidity Index for both groups was five. @entity625 @entity1 were younger; only eight out of 29 Elixhauser comorbidities were higher. @entity625 @entity1 had higher incidence of @entity281 (OR 1.72, p<0.001), @entity2688 or @entity2080 (OR 1.19, p<0.001), knee wound complications (OR 1.80, p<0.001), TKA revision (OR 1.23, p=0.01), and arthrotomy/incision and drainage (OR 1.55, p<0.001). Blood transfusion rate was lower in @entity625 @entity1 . There were no significant differences in bleeding complications, @entity3029 , broken prostheses, @entity3564 , @entity3061 and polywear, @entity531 , and extensor mechanism rupture. DISCUSSION AND CONCLUSION: This study represents, to our knowledge, TKA outcomes in the largest cohort of @entity625 @entity1 to date. Our findings indicate that these @entity1 are at higher risk for many, but not all, postoperative surgical complications despite being as healthy as @entity1 receiving TKA for primary @entity571 .
