1. What are the diagnostic criteria for elbow PJI? (clinical criteria, radiographic criteria, intraoperative findings, pathology, cultures, serum biomarkers)
  2. Does previous surgery  (arthroscopic, fracture fixation, other non-arthroplasty) increase the risk of subsequent elbow PJI after elbow arthroplasty?
  3. What are the optimal prophylactic peri-operative antibiotics for patients undergoing elbow arthroplasty?
  4. Should antibiotic-impregnated cement be used during primary elbow arthroplasty? 
  5. Should antibiotic-impregnated cement be used during revision elbow arthroplasty? 
  6. What is the role for serum ESR, CRP, or WBC count in the evaluation of an elbow arthroplasty for PJI?
  7. Is there a role for preoperative joint aspiration in the evaluation of an elbow arthroplasty for PJI?
  8. Is there a role for preoperative joint aspiration prior to second stage revision after treatment of elbow PJI? 
  9. What is the role of intraoperative histology examination in the evaluation of an elbow arthroplasty for PJI?
  10. Is there a role for sonification of retrieved arthroplasty implants from an elbow in diagnosis of a possible PJI?
  11. Do molecular techniques have a role in diagnosis of elbow PJI?
  12. Is there a role for irrigation and debridement with implant retention when treating acute elbow PJI? Should modular implant parts be exchanged?
  13. What are the indications for one-stage and two-stage exchange arthroplasty when treating an acute or chronic elbow PJI?
  14. What is the role of permanent resection when treating a chronic elbow PJI?
  15. What is the role of arthrodesis when treating a chronic elbow PJI?
  16. Should all foreign material (including cement) be removed during resection arthroplasty of an infected elbow?
  17. Is there a role for chronic antibiotic suppression in management of elbow PJI?
