Anterior cruciate ligament (ACL) is one of the most commonly injured structures in distortion injuries of the knee joint. Currently, there is no consensus among the professional community regarding the basic principles and timing of ACL injury management. An analysis of several retrospective studies from the 2008-2023 period provides information on ACL preservation procedures and a comparison of these results with those of ACL reconstruction surgery using a graft. The most comprehensive information was provided by a large meta-analysis conducted by Van der List et al. in 2019, which compared 1101 patients from 13 studies who had undergone an ACL preservation...

Significant malrotation of the femur after osteosynthesis is a serious complication of treatment and has a number of consequences for the patients and causes deterioration of their quality of life. Therefore, it is necessary to be familiar with intraoperative techniques to control the correct rotation, mostly clinical and radiological, which give us the possibility to minimize rotational errors. In the postoperative period, with even a slight suspicion of malrotation, it is necessary to proceed to its exact verification and, in indicated cases, to perform necessary correction. We recommend one of the CT techniques as a very reliable method, however...
