Every year many people suffer from knee injuries. Previous studies on patients with knee injuries have shown that about 40% of knee injuries are Ligament injuries, and about 50% of the ligament injuries are the Anterior Cruciate Ligament (ACL) injuries. Along with other methods, knee arthrometers are widely used to diagnose ACL injuries. In the current research, a knee arthrometer was designed and developed to provide a reliable and repeatable measurement of knee laxity under anterior–posterior applied loads. Test–retest configurations to examine repeatability of the device resulted in less than 1.5-mm difference for more than 97% of tests under applied loads of up to 90 N. These tests included 166 tests on the left knees and 147 tests on the right knees of 37 healthy subjects. Also, this device was tested on 27 confirmed ACL ruptured patients, and the results were analyzed to find a better criterion than standard criteria to diagnose ACL rupture using knee arthrometers by finding specificity and sensitivity of the device using those criteria. Among the 20 criteria evaluated, a combination of side-to-side difference under 150 N of applied load, and CI@90-60 (compliance index calculated between 90 N, and 60 N) resulted in the best sensitivity (96.4%) and specificity (100%).

Background Little is known about the evolution of anterior cruciate ligament injury rates among elite alpine skiers. Purpose To evaluate epidemiologic aspects of anterior cruciate ligament injuries among competitive alpine skiers during the last 25 years. Study Design Descriptive epidemiology study. Methods Data were collected from elite French national teams (379 athletes: 188 women and 191 men) from 1980 to 2005. Results Fifty-three of the female skiers (28.2%) and 52 of the male skiers (27.2%) sustained at least 1 anterior cruciate ligament injury. The overall anterior cruciate ligament injury incidence was 8.5 per 100 skier-seasons. The primary anterior cruciate ligament injury rate was 5.7 per 100 skier-seasons. The prevalence of reinjury (same knee) was 19%. The prevalence of a bilateral injury (injury of the other knee) was 30.5%. At least 1 additional anterior cruciate ligament surgery (mean, 2.4 procedures) was required for 39% of the injured athletes. Men and women were similar with regard to primary anterior cruciate ligament injury rate (P = .21), career remaining after the injury (P = .44), and skiing specialty (P = .5). There were more anterior cruciate ligament injuries (primary, bilateral, reinjuries) among athletes ranking in the world Top 30 (P < .001). Anterior cruciate ligament-injured athletes had a career length of 7.5 years, whereas athletes with no anterior cruciate ligament injury had a career of 4.5 years (P < .001). Finally, injury rates remained constant over time. Conclusion Anterior cruciate ligament injury rates (primary injury, bilateral injury, reinjury) among national competitive alpine skiers are high and have not declined in the last 25 years. Finding a way to prevent anterior cruciate ligament injury in this population is a very important goal.
