Zusammenfassung: | Maximizing tibial coverage is an important consideration in total knee replacement
arthroplasty to provide stability and even load transfer and to improve long term
survival rate of the implants. We evaluated the coverage, underhang and overhang ratio
for the proximal tibial resection surface during total knee replacement arthroplasty in
Koreans. After cutting the proximal tibia, the outline of tibial resection surface was
traced manually. We compared 5 tibial tray designs, AGC(Biomet, Warsaw, U.S.A.),
Advantim(Wright medical technology, Arlington, U.S.A.), AMK(DePuy, Warsaw, U.S.A),
MG II(Zimmer, Indiana, U.S.A.), Series 7000(Osteonics, New Jersey, U.S.A.), which have
been commercially used in Korea for total knee replacement arthroplasty. The average
percentage of coverage area were 83.3% in AGC, 81.6% in AMK, 80.3% in MG II, 80.2%
in Advantim and 76.9% in Series 7000. The average percentage of underhang were
16.7% in AGC, 18.4% in AMK, 19.6% in MG II, 19.8% in Advantim and 23,1% in Series
7000. The average percentage of overhang were measured 7.97% in AGC, 7.86% in
AMK, 8.01% in MG II, 8.77% in Advantim and 10.14% in Series 7000. So average
coverage percentage of tibial cutting surface was 80.5% in Koreans. The factors which
affect the optimal coverage, were the shape, dimensional interval of tibial trays and the
number of practically useful tibial trays for Koreans. |
