OBJECTIVE: To identify expression profiles (EP) associated with aseptic loosening of total knee arthroplasty (TKA) and to compare them with EP observed in total hip arthroplasty (THA), and primary knee and hip osteoarthritis (OA). DESIGN: Gene EP of TNF, IL-6, IL-8, CHIT1, BMP4, CCL3, CCL18, MMP9, RANKL, OPG, DC-STAMP and SOCS3 were assessed using quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) on tissues retrieved from patients with aseptically failed TKA (n = 21), THA (n = 41) and primary knee (n = 20) and hip (n = 17) OA. Immunohistochemistry was applied to localize the proteins. RESULTS: When compared to knee OA, the pseudosynovial tissue in TKA exhibit (1) elevation of alternative macrophage activation marker (CHIT1), chemokine (IL-8), and a proteolytic enzyme (MMP9); (2) downregulation of pro-inflammatory cytokine (TNF), osteoclastic regulator (OPG) and a stimulator of bone formation (BMP4); (3) no difference in IL-6, CCL3, CCL18, RANKL, DC-STAMP and SOCS3. The EP in TKA differed from EP in aseptically failed THA by lower CCL3 and DC-STAMP mRNA and protein expression. EP of all studied inflammatory and osteoclastogenic molecules were similar in knee and hip OA. CONCLUSIONS: Comparing to OA, aseptic loosening of TKA is associated with upregulated expression of CHIT1, IL-8 and MMP9, dysregulated RANKL:OPG ratio and low levels of inflammatory cytokines. Similar cytokine profiles were associated with primary knee and hip OA. Further research is required to explain the differences in CCL3 and DC-STAMP expression between failed TKA and THA.
