Arthroscopic diagnosis was used to determine the incidence of the most frequent injuries to the knee's internal structures associated with ACL tear as well as ones without ACL tear. The most frequent finding associated with a recent ACL tear was the LM tear (72.7%). There is a statistically significant incidence of recent LM tear in knees with a recent ACL tear compared with recently injured knees without an ACL tear (P < 0.001). A statistically significant incidence of longitudinal LM tear was found in knees with a recent ACL tear compared with recently injured knees without an ACL tear (P < 0.001). Longitudinal tears were present in 63.6% of the knees with a recent ACL tear or in 87.5% of all knees with a recent LM tear. No statistically significant difference was found in the incidence of LM tear in the knees with a recent ACL tear compared to the incidence of LM tear in knees with an old ACL tear (P > 0.05). The posterior horn was most frequently injured (71.5% vs 64.0%). A significant difference between the findings in the various patient groups studied supports the hypothesis that longitudinal LM tears in an ACL-deficient knee do not involve secondary meniscal pathology but that their onset derives from a primary recent injury. Most probably, the recent LM lesion does not evolve in meniscal length and depth. This hypothesis needs thorough investigation.

Background and Objectives: People employed in emergency medical services represent a professional group which encounters events beyond ordinary human experience, great work demands, the risk of professional disputes, and stressful situations. The goal of this study is to examine the presence of mobbing and violence at work, as well as their influence on work ability of emergency medical doctors. Materials and Methods: The survey is conducted in Emergency Medical Service (EMS) in Niš in the period between December 2017 and January 2018. Using standardized questionnaires on psychosocial conditions in work environment (COPSOQ II) and work ability index (WAI) this study encompasses 79 doctors. For estimation of the examined factors’ influence on WAI linear regression analysis was used. Results: EMS doctors were exposed to abuse in 30.4% of the cases. The decline in WAI is significantly related with exposure to violence by patients (β = 0.727), exposure to physical violence (β = 0.896), exposure to abuse several times (β = 0.691) and exposure to ill-treatment by patients (β = 0.750). Conclusion: The results indicate that in the examined doctors mobbing and workplace violence are very much present and have a negative impact on their work, and therefore on the quality of health care.
