Injury to the anterior cruciate ligament (ACL) of the knee is the most common ligament injury that requires operative treatment. Patient treatment can be non-operative and operative. So far, multiple ACL reconstruction (ACLR) techniques using a variety of graft types and implants that fixate the grafts have been described. Since 1995, titanium buttons with a loop have been used as implants for suspensory fixation of the graft in the femoral tunnel during ACLR. There are two types of titanium buttons in use: one with a fixedlength loop and the other with an intraoperative adjustable-length loop. This randomized prospective study presents a comparative analysis of results after ACLR using two implant types for suspensory graft fixation in the femoral tunnel. The post-operative knee stability was assessed 24 months after surgery using the Lachman test and the lateral pivot shift test, as well as the KT-1000 arthrometer test. In patients whose graft was fixated using a fixedlength loop implant, the mean post-surgery knee stability, measured with the KT-1000, was 1.167 +/-0.780; in patients whose graft was fixated using an adjustable-length loop implant, the mean value was 1.100+/-0.894 (P=0.605). The mean post-surgery IKDC score for the fixed-length loop group was 84.887 +/-9.0207, while for the adjustable-length loop the score was 88.327 (+/-7.302). The mean Lysholm score was 93.50+/-6.872 for the fixedlength loop group of patients and 94.00 +/-5.527 for the adjustable-length loop group. The results of this study lead to a conclusion that both types of implants can be used with success during ACLR, because the functional results of operative treatment using both implants were identical after surgery.

This study aimed to collect relevant data from current studies on the effects of aerobic exercise on Children and Young Peoples’ body composition. The following databases were reviewed: Google Scholar, Mendeley, SCIndeks, and KOBSON. The criteria for the analysis of the papers were as follows: the period of publication of papers from 2008 to 2020, longitudinal studies conducted in English, a sample of respondents aged 7 to 20 and the type of results for the purposes of a systematic review. The final analysis included 15 studies, which were analysed and presented, and the analysis of the obtained results shows that the effects of aerobic exercise have a positive effect on the body composition of children and young people. The results of the research can be used by future research in order to find adequate literature on the effects of aerobic exercise on children and young peoples’ body composition.

The aim of this study was to examine the efects of Delair`s mask on facial skeleton in patients with Class III antero-posterior jaw relationship. Two groups of children were evaluated. The first group of 34 children with Class III was treated with Delair`s mask. The second group of 46 children with Class III did not receive any orthodontic treatment and was presented as a control group. In the first group pretreatment and post treatment radiographic tracing was done while second tracing in the control group was done a year after diagnostic radiographic tracing. Analysis of the skeletal facial profile was done measuring SNA, SNB and ANB angles. Rotation of the maxillary base (NS/SpP), rotation of the mandibular base (NS/MP) and vertical relationship between jaws (SpP/MP) were also measured. The results were statisticaly analysed using T test, descriptive statistics and Wilcoxon`s test. The results of this study showed changes in facial skeleton in children treated with Delair`s mask compared to the control group. In the first group of children SNA and ANB angles were increased and the SNB angle was decreased.

Introduction. Hip dysplasia with subluxation represents insufficient coverage of the femur's head placed in the dysplastic acetabulum. This lack of coverage ranges from barely noticeable to condition where half of femur head is uncovered by acetabulum. The caput-collum-diaphyseal angle of the proximal femur and anteversion angle of collum are increased, Wiberg's angle is less than 15° and Ménard-Shenton line is interrupted. Hip joint degeneration occurs very early. When radiological signs of hip joint degenerative changes are discovered in elderly they are associated with pain, limited movements and leg shortening. Case report. We present a 53-year old female treated conservatively in childhood because of hip diyplasia with subluxation. After pregnancy, right hip pain emerged. Clinical and radiological examinations revealed hip subluxation with the signs of degenerative osteoarthritis. Initial treatment was conservative and included drugs and balneophysical procedures. Since pain and movement impairment progressed and became constant, a hip replacement using cementless total endoprosthesis with Fitmore ® Hip Stem was done. In the pre-operative preparation, anteroposterior x-ray of the hip(with third of the proximal femur) was made. This X-ray enabled precise planning of implantation endoprosthesis component. The early postoperative course was uneventful with very good therapeutic effect. Following successful physical rehabilitation, the patient returned to work and full life activity. Conclusion. Implantation of the cementless endoprosthesis with Fitmore ® Hip Stem in the treatment of secondary hip osteoarthritis is a good choice in the treatment of young patients with good bone quality. Future clinical and radiological follow-up and comparative studies are needed to show the advantages of this type of stem compared to the classical cementless long stem.

Treatment plan in contemporary orthodontics cannot be imagine without analyzing soft tissue facial characteristics besides assessment of jaw and dental relationships. Aim. Using a questionnaire, we aimed this study at establishing facial characteristics, in relation to sagittal and vertical facial ratios, which are considered aesthetically acceptable, and which could be altered by the means orthodontic treatment. Material and Method. The research was conducted in persons from 23 to 30 years of age whose photographs were taken in standard conditions. Photographs of three patients with different facial profiles were chosen (Class I, Class II and Class III). Every photo was modified in six new profiles by changing facial features. This included mesial and distal shift of maxilla and mandible, as well as increase and decrease of lower facial height. Results. The results showed that straight profile, which is most often present in normal jaw relationships, is considered the most beautiful, furthermore slightly convex profiles are also considered very attractive. Convex profile is connected with distal jaw relationship and its intensity affects facial attractiveness. Concave profile in patients with mesial jaw relationship is aesthetically the least acceptable
