Background: We sought to determine (1) the success rate of debridement, antibiotics, and implant retention (DAIR) for acute periprosthetic joint infection (PJI) of the knee in patients with acute postsurgical infection and in those with acute hematogenous infection via a multicenter study, (2) the factors related to the failure of DAIR for overall acute PJI and acute hematogenous PJI via subgroup analysis, and (3) whether the PJI recurrence patterns differed between the two groups over time after DAIR. Methods: This retrospective multicenter study included 101 acute knee PJI. Acute postsurgical PJI was defined as PJI diagnosed < 3 months following initial knee arthroplasty surgery. DAIR was performed for 34 cases of acute postsurgical PJIs (postsurgical group) and 67 cases of acute hematogenous PJIs (hematogenous group). The success rates between groups were compared, and factors related to DAIR failure were analyzed. Results: The overall success rate of DAIR was 77%. The success rate tended to be higher in the postsurgical group than in the hematogenous group (p = 0.060). However, there was no significant factor related to DAIR failure in the subgroup analysis of acute hematogenous PJIs. In the postsurgical group, the recurrence of PJI occurred until 3 months, whereas in the hematogenous group, recurrence occurred for up to 2 years. Conclusions: The failure rate tended to be higher in the acute hematogenous PJI group than in the acute postsurgical PJI group. Since acute hematogenous infections may recur for a longer period than postsurgical infections, careful follow-up is required after DAIR.

This study is the 3rd result of ecological researches on the freshwater shell-fish to be investigated from April, 1975 to December, 1977. The result investigated from the early embryo to the grown-up shell-fish is as follows: 1. Anodonta (Sinanodouta) fukudai is outer gill breeder and cleavage develope in the marsupium. 2. A. fukudai that lives in Iri district begins the cleavage of its fertilized egg on September, glochidium is spawned from the marsupium. It is attached itself to the freshwater fish and is parasitic on it during February and March. The period of parasitism is 10∼20 days, though it is different from the temperature. 3. A. fukudai becomes glochidia through two cell stage… D shaped larva stage, then it puts its foot and lives freely after the parasitism of freshwater fishes. 4. D shaped larva does the vigorous rotary motion toward the watch direction. 5. Glochidium takes exercise of the opening and closing of shell and has keen hook or larval thread of foot. 6. A. fukudai lives on the vegetable planktons, the green algaes are in a large amount among them.
