In addition, the femoral component interferes with thescrews or K-wires to be inserted from distal direction for fixation of the fracture. Patients andMethods. Four knees in 4 patients (all female; average age, 81.5 +/- 2.6 years) with the fractureafter TKA were treated with revision TKA. Follow-up period was between six months and 3years postoperatively Operative technique. All operations were performed with the patient inthe supine position and using a curved anterior (Payer) approach with or without osteotomy ofthe tuberositas tibiae. The femoral component was removed with detachment from fracturedbony fragments. New femoral component with long stem for fixation of the fracture wereinserted with bone cement in each case. Post-operative regimen. On the third postoperativeday the patient began flexion and exension exercise of the operated knee joint with arehabilitation programmed by clinical path under the supervision of a physiotherapist. The useof crutches for ambulation was begun on the 10 th to 14 th postoperative day, and the extent ofweight bearing was allowed individually according to the stability of the fixation of the fracture.The time to full weight bearing in each patient was 3 to 8 weeks postoperatively. Results.Postoperative courses were uneventful in all of the cases. The supracondylar fracture of thefemur was rigidly fixed and healed radiographically within 8 weeks postoperatively in eachcase. The JOA scores were improved in all od the cases. The mean Japanese OrthopaedicAssociation (JOA) scores for the knees improved to 90 points postoperative. No femoralcomponents had definite radiographic evidence of loosening and were re-revised. Discussion.file:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
