Traumatic injuries of the knee joint are one of the main factors resulting in the loss of mobility among football players. According to the reports of many researchers, the damage to the soft tissues predominates in the structure of traumatic injuries of the knee joint; therefore, such diagnostic technique as ultrasound scanning is very helpful in determining the nature and extent of injuries and in making decision on the necessity of the surgical intervention. The aim of this study is to investigate and systematize ultrasound criteria for various types of traumatic injuries of the soft tissues of the knee joint in acute and chronic trauma in football players. The analysis of the findings of ultrasound scan of the knee joints in 36 football players with sports injury was carried out. The following echographic data were assessed: homogeneity, echogenicity, integrity of the tendon contours, the presence of effusion in the bursae and tendon sheaths, the number of vascular signals in the affected area. In the first group of patients, the analysis of ultrasound signs revealed the following structural changes: separate meniscus ruptures were diagnosed in 6 (27, 3%) athletes; combined lesions of the menisci and ligamentous apparatus – in 9 (40, 9%) with signs of damage to the menisci and ligaments characteristic of acute trauma; separate ligament ruptures were diagnosed in 7 (31, 8%) athletes. In the second group of the patients, sonography confirmed suffered meniscus tears in 3 (21, 4%) athletes; combined lesions of the menisci and ligaments in 7 (50,1%) footballers; rupture of the ligamentous apparatus in 4 (28,5%) individuals. Fresh injuries to the menisci and ligaments against the background of previous ruptures were not diagnosed during past ultrasound examinations and resulted in the impairment of the ratio of the load distribution on the limb that could provoke repeated trauma to the menisci and ligaments. Ultrasound scanning for acute and chronic injury of the knee joint in football players can be considered a reliable informative imaging technique, which allows assessing the severity of damage to the menisci, ligaments, soft tissues and makes it possible to choose the proper tactics of further treatment.

Summary Aim: Multiple procedures for the quantification of activity leakage in radiation synovectomy of the knee joint have been described in the literature. We compared these procedures considering the real conditions of dispersion and absorption using a corpse phantom. Methods: We simulated different distributions of the activity in the knee joint and a different extra-articular spread into the inguinal lymph nodes. The activity was measured with a gammacamera. Activity leakage was calculated by measuring the retention in the knee joint only using an anterior view, using the geometric mean of anterior and posterior views, or using the sum of anterior and posterior views. The same procedures were used to quantify the activity leakage by measuring the activity spread into the inguinal lymph nodes. In addition, the influence of scattered rays was evaluated. Results: For several procedures we found an excellent association with the real activity leakage, shown by an r² between 0.97 and 0.98. When the real value of the leakage is needed, e. g. in dosimetric studies, simultaneously measuring of knee activity and activity in the inguinal lymph nodes in anterior and posterior views and calculation of the geometric mean with exclusion of the scatter rays was found to be the procedure of choice. Conclusion: When measuring of activity leakage is used for dosimetric calculations, the above-described procedure should be used. When the real value of the leakage is not necessary, e. g. for comparing different therapeutic modalities, several of the procedures can be considered as being equivalent.

SummaryTotal removal of a knee joint meniscus is followed by osteoarthritis in many mammalian species. Altered load-bearing has been observed in the human knee following meniscectomy but less is known about biochemical effects of meniscectomy in other species. Using pressure sensitive paper in sheep knee (stifle) joints it was found that, for comparable loads, the load-bearing area on the medial tibial condyle was significantly reduced following medial meniscectomy. Also, for loads of between 50 N and 500 N applied to the whole joint, the slope of the regression of contact area against load was much smaller. Following medial meniscectomy, the ability to increase contact area as load increased was markedly reduced.The load bearing area on the medial tibial condyle was reduced following meniscectomy.

Research  background  and  hypothesis.  Proprioception  is  important  in  the  prevention  of  injuries  as  reduced proprioception  is  one  of  the  factors  contributing  to  injury  in  the  knee  joint,  particularly  the  ACL.  Therefore, proprioception appears not only important for the prevention of ACL injuries, but also for regaining full function after ACL reconstruction.Research aim. The aim of this study was to understand how proprioception is recovered four and five months after anterior cruciate ligament (ACL) reconstruction.Research methods. The study included 15 male subjects (age – 33.7 ± 2.49 years) who had undergone unilateral ACL reconstruction with a semitendinosus/gracilis (STG) graft in Kaunas Clinical Hospital. For proprioceptive assessment, joint position sense (JPS) was measured on both legs using an isokinetic dynamometer (Biodex), at knee flexion of 60° and 70°, and at different knee angular velocities of 2°/s and 10°/s. The patients were assessed preoperatively and after 4 and 5 months, postoperatively.Research results. Our study has shown that the JPS’s (joint position sense) error scores  to a controlled active movement is significantly higher in injured ACL-deficient knee than in the contralateral knee (normal knee) before surgery and after four and five months of rehabilitation.  After 4 and 5 months of rehabilitation we found significantly lower values in injured knees compared to the preoperative data. Our study has shown that in injured knee active angle reproduction errors after 4 and 5 months of rehabilitation were higher compared with the ones of the uninjured knee. Proprioceptive ability on the both legs was  independent of all differences angles for target and starting position for movement. The knee joint position sense on both legs depends upon the rate of two different angular velocities and the mean active angle reproduction errors at the test of angular velocity slow speed was the highest compared with the fast angular velocity. Discussion and conclusions. In conclusion, our study shows that there was improvement in mean JPS 4 and 5 months after ACL reconstruction, but it did not return to normal indices.Keywords: knee joint, joint position sense, angular velocity, starting position for movement.
