BOVINE BONE SUBSTITUTE IN REVISION KNEE REPLACEMENT

Introduction: Seven patients underwent successful revision total knee replacement for aseptic loosening. Bovine bone graft was used to reconstruct bony defects in all.Materials and methods: This is a retrospective review. Between April 2000 and March 2003, bovine bone (Tutobone™, Wescott-Medical, UK) was used in 7 revision arthroplasty cases (4 right knees & 3 left). There were 5 males and 2 females. The average age was 70.4 years. All revisions were carried out for aseptic loosening of the prostheses associated with massive osteolysis and bone loss.The bone defects on the tibia and femur were as follows: (Obtained from operative records. Classified according to Anderson Orthopaedic Research Institute classification)Type IType IIAType IIBType IIITIBIA3121FEMUR2320The tibial defects were corrected by impaction grafting and femoral condyle defects were corrected by using bovine bone as bulk grafts. Semi-constrained constrained stemmed cemented modular knee prostheses (TC3, Depuy) were used in all. Clinical ...
