H. Jonsson et al., LAXITY AFTER CRUCIATE LIGAMENT INJURY IN 94 KNEES - THE KT-1000 ARTHROMETER VERSUS ROENTGEN STEREOPHOTOGRAMMETRY, Acta orthopaedica Scandinavica, 64(5), 1993, pp. 567-570
We examined 94 knees with chronic anterior cruciate ligament injuries,
55 of which had been operated with ligament reconstruction, using the
KT-1000 arthrometer (89 N anterior force) and roentgen stereophotogmm
metry (RSA, 150 N anterior, 80 N posterior force). In intact knees the
tibial displacement did not differ between the methods. In injured kn
ees, operated or not, the KT-1000 recorded smaller AP translations and
side-differences than RSA. Thus, the stabilizing effect of reconstruc
tive surgery may be overrated, if evaluated with the standard KT-1000
technique
