236, indicating fair agreement. When the menisci were evaluated separately, 65.85% sensitivity, 45.45% specificity, and 54.16% accuracy were found for the medial meniscus, while 46.15%, 79.51%, and 75.0% for the lateral meniscus, respectively. JAK Inhibitor I ic50 The accuracy was 62.09% in whose patients that arthroscopy was performed up to 3 months after MRI and 67.18% in those that this time frame was more than 3 months before surgery. The 54 meniscal injuries occurred more frequently in the posterior horn; most injuries had a longitudinal pattern and were located in the red-red (vascular) zone. We suggest that magnetic resonance imaging is only moderately accurate for the prediction of meniscus reparability.Recently there has been a considerable surge in interest in volleyball by both physiotherapists and orthopaedic surgeons. Only few previous studies specified the nature, frequency, and demographics of volleyball injuries. The study was conducted during two league seasons. After the approvals of local bioethics committee and clubs` authorities, contact with the club's doctors was established. A special survey was designed to standardize the process of acquiring data on a weekly basis. One-hundred-and-ninety-eight women and 301 men were under supervision of the research group. On average, 45% of all players (56% males and 26% females) suffered from injuries and musculoskeletal disorders over two seasons. Relatively high incidence of injuries during matches was between 17.3 and 33.8 injuries per each 1000 hours of playing. Almost 50% of musculoskeletal problems occurred in the first phase of the season. Over 50% of musculoskeletal problems were reported during trainings. The blockers are the most affected players in both sex groups. Acute injuries mainly involved knee and ankle joints, while chronic problems affected knee, shoulder, spine and abdominal muscles. Professional volleyball is not a safe sport, especially during a league season. Attention should be especially paid to ankle, shoulder and knee joints, which are the most commonly injured structures. The study revealed that blockers were the most susceptible to injuries and should be protected by special training regime. These findings can help to prepare sports medicine personnel and to guide further related research to prevent injuries among volleyball professionals.The aim of the study was to quantify normal cervical disc space measurements and to generate a normal values' database. Furthermore, during operative restoration of a degenerated intervertebral disc, it is difficult to calculate the amount of distraction required to restore the collapsed space to its normal height. A secondary purpose is personalizing the anatomical correction. Therefore, we expressed disc height based on measurements of its neighboring disc as an equation, by using simple linear regression. We reviewed MRI studies from asymptomatic healthy subjects (16 men-24 women, mean age 27.25 years). We measured midsagittal anterior, middle and posterior vertebral body and disc height, and disc diameter from C3 to T1 vertebra. We calculated mean disc height, disc height index (DHI) and disc convexity index per spinal level. C6-7 mean and anterior disc height were significantly greater than all respective measurements, except C5-6 (p less then 0.01). Middle C6-7-disc height was significantly greater compared to respective measurements in every other level (p less then 0.01). C5-6, C6-7 and C7-T1 mean disc height is significantly greater in men. Middle disc height is the greatest among disc heights in every spinal level. DHI does not differ between sexes, it increases from C3-4 to C5-6 with a slight decrease in C6-7, while its value significantly decreases in C7-T1 (p less then 0.0001). These measurements could be used for anatomical, individualized restoration of the degenerated intervertebral disc; thus, avoiding overdistraction. Our data could improve preoperative templating or implant design.Despite the great advances of the technology in the joint prosthesis and the high execution rate of total knee arthroplasty (TKA), there are still about 15% of clinical unsatisfactory rate in this surgery. TKAs are currently performed using a mechanical alignment of the knee, correcting varus/valgus deformities with the purpose to achieve a longer implant survivorship, but this surgical technique results in an alteration of the normal knee kinematics. Nowadays, the idea to restore the pre-arthritic alignment of the knee with the goal to obtain a normal kinematics and better functional results becomes more and more consistent and the kinematic alignment (KA) was developed as alternative to the mechanical one. The aim of this preliminary study is to analyse the functional outcomes in patients who underwent KA-TKA in the short-term follow-up and to compare them with those obtained in patients treated by the mechanical alignment (MA) TKA. Therefore, skeletally mature patients, with no history of previous knee surtend the sample size to obtain reliable clinical evidences.Patellar dislocation represents a rare but invalidating trauma. Indeed, 94 to 100% of patients suffer from medial patellofemoral ligament (MPFL) rupture just after the first patellar dislocation, and approximately half of these patients develop recurrent dislocations. MPFL reconstruction is a commonly performed surgery for patellofemoral instability. Anatomic reconstruction of the MPFL restores patellar stability in patients with recurrent patellar instability with neutral lower limb alignment. We describe a technique, which creates an anatomic reconstruction using trans-osseous suture loop. Conclusion Compared to similar techniques, the described procedure has the following advantages smaller tunnels, less donor side morbidity, reduced risk of graft failure, minimal invasiveness, more appealing cosmetic results and easily reproducible. Complications and outcomes of this technique, including the risk for patellar fracture, must be further evaluated in a larger patient cohort with longer follow-up.There is limited evidence whether increased growth-factor and stem-cell influx during bone tunnel drilling for ACL-reconstruction enhances clinical results of microfracture treatment of small cartilage defects. The goal of this study was to compare clinical and radiological results in patients treated with microfracture alone and patients treated with microfracture plus ACL-reconstruction. A total of 67 patients that were either treated with microfracture alone (primary stable knees, n= 40) or microfracture plus ACL-reconstruction (ACL deficient knees, n= 27) were included and prospectively evaluated. Subjects were preoperatively assessed radiologically using the MR-based AMADEUS-score (Area Measurement and Depth & Underlying Structures) and clinically using the Lysholm-score before the intervention. At minimum 24-month follow-up, the regenerate tissue was assessed by the MR-based MOCART-score (Magnetic resonance observation of cartilage repair tissue) and by use of the Lysholm-Tegner-score for clinical evaluation.
