Available data is mostly based on the analyses of mixed populations. The objective was to evaluate the clinical and microbiological features and outcomes of BJI in young adults vs. older patients. Methods: We carried out a retrospective cohort study comparing 341 episodes (ep) of BJI in elderly pts (>65 yo) vs. 336 ep in a younger (>16 yo and 65 yo (47.2% male; mean age 73.5, r:65-103) and 336 (37%)

The one or two-stage exchange arthroplasty (EA) or resection arthroplasty (RA) are the conventional surgical approach suggested. The objectiv was to analyze the clinical and microbiological features and the outcome of PJI treated with the conventional surgery approach. Methods: We performed a retrospective cohort study of PJI episodes (ep.) treated with EA or RA. The medical and surgical approach were not previously standardized, but individualized according to the patient and the treating team. Statistical analysis: we used the Stata 10, applying the Chi 2 test. Difference was considered statistically significantatp50 mm/h: 66.3%. Microbiology: 57.6% grampositive cocci (S. aureus 35.2%, CoNS 13.6%, other 9.2%), 10.4% gramnegative bacilli (P. aeruginosa 8% Enterobacteriaceae 4%); polimicrobial 24%, fungi 1.6%, anaerobic bacteria 0.8%, culture negative 5.6%. Antibiotic therapy: TI: 20 weeks (median; IR 12-26); oral 50%, switch to oral therapy 37.5%, parenteral only 12.5%.TS in 28,9% ep; median 24 weeks (IR 11-37). Surgical treatment: two-stages EA 50.4%, one-stage EA 13.9%, AR 35.7%. Follow up: 27 months (median; IR 16-50). Outcome: cure/ improvement: 109 (87.2%), relapse 9 (7.2%), failure 3 (2.4%), not evaluable (3.2%). In the univariate analysis, only PJI treated with two-stages EA had a better outcome (p = 0.04). Conclusion: The management of PJI should be individualized according to the patient characteristics and evaluated with a team (orthopedic surgeons and infectologist). This is the key in determining the functional status of the prosthesis, in order to define the surgery strategy. Twostages EA is the method that achieves better control of infection. There were no significant differences in the outcome with the others variables studied.
