THE WAYS OF BONE DEFECTS COMPENSATION IN REVISION KNEE ARTHROPLASTY
Abstract
During 83 revision TKA we found out the need of bone defect compensation in 93,3% of cases. The autologic bone was used in 12 (7,5%) patients, spongeous allograft in 45 (28,1%), femoral head allograft in 10 (6,3%), structural allograft in 22 (13,8%), femoral or tibial sleeves in 17 (10,6%) and femoral or tibial augmentation blocks in 50 (31,3%). Middle-term results of revision TKA (27 months in average) were evaluated in 57 (68,7%) patients using KSS and WOMAC scores. Positive results were achieved in 48 (84,2%) patients. In 9 (10,8%) cases deep infection developed in different periods of time after surgery. Hence during revision TKA the surgeon should be ready to use different methods of bone defect compensation.
