Avascular Necrosis of Hip, Degenerative Hip Joint Disease
Conditions
Brief summary
Revision total hip replacement arthroplasty is a surgery having intra- and postoperative substantial blood loss. The investigators will investigate the relationship between the various hematologic variables and postoperative bleeding volume.
Interventions
