Abstract:
Revision total knee replacement (TKR) is often associated with the necessity to reconstruct a certain amount of bone loss. In a retrospective study we reviewed the records of 137 patients who had undergone revision TKR in our department between 1990 and 1996, due to loosening or inflection. Bone allografts were used in 91 patients (67%) to accomplish stable, new prostheses. Three types of bone loss were identified in this group: Type I - minor, Type II - moderate, and Type III - large bone defects, located on either side of the knee joint - A, or both sides - B.The treatment results of these 91 patients, according to the type of bone loss, are presented, showing good functional outcome when utilizing bone allografts in revision TKR. However, careful preoperative planning, identification of bone loss type, and a well-equipped bone bank are mandatory to the success of the operation.
