Abstract
Objective: despite the fact that anterior cruciate ligament injuries are the most common ligament injuries, the problem of making a quick and accurate diagnosis still exists. in our paper, we hypothesized that a modification of the Lachman test — BK21 (Kacprzak test), in comparison to the Lachman test and Drop Leg test will allow for a significant reduction of pain during the test, and thus for less muscular defense, more relaxation, and more reliable test results, whose sensitivity and specificity will be confirmed by magnetic resonance imaging.Materials and methods: using the patient’s subjective pain rating scale, the Numerical Rating Scale (NRS), we were able to easily assess which way of performing the test was less traumatic for the patient. a physical examination in the form of a comparison of those two visits was performed at the private medical office Orto Med Sport in 203 patients with suspected anterior cruciate ligament tear.Results: the BK21 modification (Kacprzak) test was on average 3 points less painful on the NRS scale than the classic Lachman test and 1 point less painful than the Drop Leg test, while the same principle of operation and analogous endpoints in both tests allow for high sensitivity and specificity of the test.Conclusion: the BK21 test was a less traumatic and painful alternative to the Lachman test.
