ABSTRACT
PURPOSE:
To investigate the clinical and radiological results after primary or revision total knee arthroplasty using fresh frozen femoral head strut allograft for severe bone defect. SUBJECTS ANDMETHODS:
Seventeen patients (18 cases) with severe bone defect were taken primary or revision TKA from 1997 to 2001 using fresh frozen femoral head allograft. 12 cases of revision TKA and 6 of primary TKA were conducted. The average age was 66 years old(55~74) and the follow up period was 29 months(12~63 months). Bone defects were found at proximal tibia in 10 cases, distal femur in 2 and both sites in 6 cases. PCL substituting TKA with extension rod were 15, and PCL retaining TKA were 3. The clinical result was assessed with the knee score of Hospital for Special Surgery(HSS) and for assessment of allograft, simple X-ray film was employed.RESULTS:
Average range of motion was increased from 71 degrees to 103 degrees and HSS score was increased from 46(18 ~68) to 83(68 ~91). With 17 of 18 femoral head strut allograft, union was seen and no clinical collapse was present. In one, partial allograft absorption was occured. The preoperative alignment was an average of 7 degrees varus(range 5 degrees~15 degrees) and postoperative alignment was averaged 6.1 degrees valgus(range 3 degrees ~7 degrees). No radiolucent lines were 2 mm or more in width, and there was no case of infection or fracture of allograft.CONCLUSIONS:
Femoral head strut allograft was a satisfactory method of managing severe bone defect in primary or revision TKA.
