The number of total knee arthroplasty (TKA) has been increasing during the past few years, as this procedure is reliable and efficacious for patients who suffered from late stage knee osteoarthritis. According to higher number this procedure on varies patient’s age, there has been increasing number of younger patients. Thus, there is potential to increase incidence of revision TKA in the future. In revision TKA, one of the major problems to deal with is the bone loss, which may affect the prosthesis placement, the alignment of the limb and prosthesis longevity. Bone loss in revision TKA varies according to the degree of severity. Management options are based on the severity and the principle of bone reconstruction, which range from bone cement, autogenous graft, allograft, metal augment, and mega prosthesis. Recently, new alloys with high porosity have been introduced with satisfactory short-tem results. In this review article, the authors summarized the scientific evidences of current treatment options and outcomes of bone loss according to the degree of severity.
