“…Of the 23 studies included for meta-analysis, six used bone scintigraphy [12, 20, 27, 34, 40, 50], four used bone leukocyte scintigraphy [20, 34, 41, 50], six used leukocyte scintigraphy [18, 28, 34, 37, 38, 50], seven used leukocyte bone marrow scintigraphy [2, 7, 9, 16, 17, 21, 34], five used antigranulocyte scintigraphy [14, 15, 40, 44, 52], and five used fluorodeoxyglucose (FDG)-PET [2, 21, 23, 50, 56]. Altogether, a total of 1027 diagnostic images, 404 (39%) with and 623 (61%) without periprosthetic knee infection, were evaluated in 1502 patients with 763 knee prostheses, of which 288 (38%) were infected (Table 1).…”
