Objective measurements of static anterior and rotational knee laxity

Abstract: Several devices allow to measure anterior and rotational static knee laxity. To date, the use of rotational laxity measurements in the daily clinical practice however remains to be improved. These measurements may be systematically integrated to the follow-up of knee injuries. Physiologic laxity measurements may particularly be of interest for the identification of risk factors in athletes. Furthermore, knee laxity measurements help to improve the diagnosis of knee soft tissue injuries and to follow up reconst… Show more

“…For measuring anterior knee laxity, the KT-1000, which achieves a sensitivity of 0.93 and a specificity of 0.93 with maximal manual force in a recent meta-analysis, 8 is one of the most commonly used devices to measure anterior knee laxity. 9 However, rotational knee laxity measurements of the tibia with respect to the femur, though being developed by different researchers, 10 , 11 , 12 , 13 , 14 , 15 are not yet widely used in the daily clinical practice. 9 Furthermore, those devices were seldom verified with a comparative instrument like a navigation system.…”

“… 9 However, rotational knee laxity measurements of the tibia with respect to the femur, though being developed by different researchers, 10 , 11 , 12 , 13 , 14 , 15 are not yet widely used in the daily clinical practice. 9 Furthermore, those devices were seldom verified with a comparative instrument like a navigation system. Therefore, the development of a simple, objective, verified and reliable tool that measures tibial rotation would be of great clinical value to document knee rotational laxity of healthy knees and injured knees.…”

“…The use of an Aircast ® Foam Walker boot to immobilize the foot and ankle and the use of a skin pointer close to the knee joint as in our study would help to minimize systematic error from foot and ankle movement. Mouton et al[ 13 , 14 ] used a prototype rottometer with a similar ski boot and delivered the torque through a rotational handle bar and measured rotation through an inclinometer attached to the bar. Tsai’s device utilized a magnetic tracking system with an Aircast ® Foam Walker boot with reliable results[ 9 ].…”

“…This issue is relevant since Mouton et al 50 determined that both anterior and rotational knee laxity appear to be greater in the contralateral, non-injured knees of ACL-injured patients than in healthy controls, suggesting that increased physiological laxity could be a risk factor for (second) ACL injuries. 51 Increased laxity is associated with more hip adduction and knee valgus during drop landings in female patients. 52 Baumgart et al 53 demonstrated that playing football and stretching led to significant increases in anterior translation of 1 mm and 2 mm, respectively, measured with the KT-1000 (MEDmetric, San Diego, California).…”
