In addition, the patient had 5 mm of anterior translation bilaterally on KT-1000 arthrometry
testing and 20.6 pounds of force on maximal muscle testing of leg extension on the right compared to 21.3 pounds on the left as measured by a handheld dynamometer.
For these reasons, we would like to use this letter to the editor to report the results of our experiments investigating whether a relatively light elastic knee sleeve would limit the degree of anterior tibial translation in computerized arthrometry tests as performed in a sample of non-injured subjects.
To control inadvertent coactivation of hamstring muscles, which may bias the results of arthrometry measurements (Steele et al., 1994), the integrated electromyographic (EMG) activity of the biceps femoris and semitendinosus muscle was simultaneously recorded and normalized to additional recordings obtained during maximal voluntary contraction (MVC).
Test-retest reliability of arthrometry measurements was excellent, as reflected by low typical measurement errors (0.08 mm) and high correlation coefficients (r = 0.99, p < 0.001).
The analysis of hip joint vibrations by various techniques (phonoarthrography, vibration arthrometry, vibroarthrography, hip auscultation) has been explored as a means to assess joint pathologies, disease status, and, recently, incipient prosthesis failure.
Vibration arthrometry in the patients with failed total knee replacement.
Anteroposterior laxity was measured with KT-1000 arthrometry, and pivot shift testing was measured both clinically and by three-dimensional electromagnetic sensors.
KT-1000 or 2000 arthrometry is the most reliable and reproducible parameter for measurement of anterior translation available.
The most widely used method to assess the efficacy of knee bracing in-vivo has been the arthrometry test in which a device is externally strapped to the lower leg and the tibial translation is recorded during anterior shear loading (Beck et al., 1986; Branch et al., 1988; Colville et al., 1986; Mishra et al., 1989; Rink et al., 1989; Risberg et al., 1999).
During arthrometry, it is important that the patella is well stabilized against the femur, so that the relative movement of the tibiofemoral joint is measured as the relative motion between the patellar and tibial sensor pads of the arthrometer.
In order to justify these findings, one has to consider the functional bracing characteristics and the arthrometry test conditions in more detail.
