Purpose: We evaluate the results of allograft using femoral head in revision total knee arthroplasty with severe bone defects.
Material and Methods: Between March 2000 and February 2005, the clinical records on 22 cases that had undergone the revision total knee arthroplasty using femoral head allograft were reviewed. Mean follow up period was 48(24~80) months. Allografts were used at proximal tibia in 12 cases, distal femur in 7 cases, both in 3 cases. We used posterior cruciate ligamental substituting component with extension rod in all cases. The clinical results were assessed with the knee score and functional score of Knee Society Knee Score(KSS), complication, union of allograft and so forth. We evaluated complications and union of the allograft.
Results: Mean degrees of preoperative and postoperative range of motion were 94+/-14 and 105+/-12 respectively. Postoperative mean knee score of KSS was increased from 45+/-10 to 79+/-8, and functional score was increased from 42+/-13 to 83+/-9. Union of allograft were observed in all cases. There were no infection, absorption and fracture of allograft.
Conclusion: We consider allograft using femoral head in revision total knee arthroplasty with severe bone defects is one of the useful method.
