Abstract PDF: PURPOSE
To analyze the midterm results of the treatment with a retrograde nail for periprosthetic fractures of the femur following total knee arthroplasty.
MATERIALS AND METHODS
Between Jan 1998 and Jan 2004, 11 cases in 11 patients were treated for the periprosthetic fractures following total knee arthroplasty. The mean follow-up was 42.0 (30~98) months and the mean age was 66.0 (57~79) years old. 2 were males and 9 patients were females. In all cases, retrograde nailing was done for the periprosthetic fractures. Postoperative range of motion, HSS knee rating score, femorotibial angle, the time required for union, complications were evaluated.
RESULTS
Postoperative range of motion was 103.6Â° degrees on an average, HSS knee rating score was 83.5 points on an average at the last follow up. The mean angulation on radiograph was valgus 6.3Â°. The mean time required for union was 4 months. One had a newly fracture line at proximal part of supracondylar fracture, but there was no significant in clinical course. There was no prostheses required revision.
CONCLUSION
It appears that retrograde nail is a reliable surgical technique for periprosthetic fractures of the femur following total knee arthroplasty with low complication rate. The midterm results in our study showed that none of the prostheses required revision.

The Treatment of Supracondylar Femur Fracture after Total Knee Replacement: Dae Kyung Bae, Hong Ku Lee, Chong Hoon Cho; J Korean Soc Fract 1994;7(1):181-186. Published online May 31, 1994; DOI: https://doi.org/10.12671/jksf.1994.7.1.181

Abstract PDF: We had five cases of the supracondylar fracture of the femur among 419 total knee arthroplasties in 330 patients that were done between January 1989 and december 1992 The incidence was 1.2%. Two cases were treated by non-operative methods. One case was treated by open reduction and screw fixation. And other two cases were treated by closed intramedullary Ender nailing. Prearthroplastic diagnosis was three cases of rheumatoid arthrltis, one degenerative arthritis and one tuberculous arthritis. The average age was 49.8 years(range, 34 to 71) and all patients were female. The supracondylar fractures occured by fall down injury and those were not associated with other injury The average duration between total knee arthroplasty and fracture was 1 year 8 months(range 9 months to 3 year 9 months). The average follow up period was 13 months(range, 6 months to 2 year 6 months). Posttreatment angulation was 2.3 degrees in AP plane and 6.7 degrees in lateral plane.
