The purpose of the present study was to examine the intermediate-term risk of periprosthetic joint infection (PJI), aseptic revision, and reoperation following primary TKA in patients with a history of septic arthritis of the native knee as compared with primary TKA performed for the treatment of osteoarthritis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      We retrospectively identified 215 primary TKAs performed from 1971 to 2016 at a single institution in patients with a history of septic arthritis of the native knee. Each case was matched 1:1 based on age, sex, body mass index (BMI), and surgical year to a TKA for osteoarthritis.

Ten-year survivorships free of any aseptic revisions were 83% and 93% (HR = 2.5; p &lt; 0.01), and survivorships free of any reoperation were 61% and 84% (HR = 2.9; p &lt; 0.01) for the septic arthritis and osteoarthritis groups, respectively. In addition, as time from the diagnosis of native knee septic arthritis to TKA increased, the relative risk of subsequent infection decreased. Preoperative and 2-year postoperative Knee Society scores were similar between the groups (p = 0.16 and p = 0.19, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>There was a 6.1-fold increased risk of PJI in patients undergoing TKA with a history of native knee septic arthritis when compared with controls undergoing TKA for the treatment of osteoarthritis, with a cumulative incidence of 9% at 10 years. Subgroup analysis of the septic arthritis cohort revealed a higher risk of any infection in patients who underwent TKA within the first 5 to 7 years after the diagnosis of septic arthritis as compared with those with a greater duration. Moreover, the 10-year rates of survival free of aseptic revision, any revision, and any reoperation were significantly worse in the native knee septic arthritis cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      Prognostic\n                      <jats:underline>Level III<\/jats:underline>\n                      .
