This requires intra-articular passage of instruments, which theoretically places the knee at risk of postoperative sepsis in the setting of open fracture. We hypothesized that the risk of knee sepsis is similar after suprapatellar or infrapatellar nailing of open tibia fractures.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Design:<\/jats:title>\n            <jats:p>Retrospective, multicenter.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Setting:<\/jats:title>\n            <jats:p>Three urban level 1 trauma centers.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Patients:<\/jats:title>\n            <jats:p>All patients treated with medullary nailing for open diaphyseal tibia fractures (OTA 42) from 2009 to 2015.

SP nailing was used in 147 fractures. There were 24 infections (16.2%), of which 16 (10.8%) were deep. Fourteen additional tibias (9.5%) required reoperation for noninfectious reasons for a total of 30 reoperations (20.4%). There were no differences in the rates of infection, deep infection, or reoperation between groups.
