This Thesis presents a design innovation in arthroscopic forceps. Based on surveying the subject-matter literature on arthroscopic surgery of the knee, design changes are proposed to alter the cutting geometry of the functional end of the instrument to improve its utility. The proposed changes are imple-mented in a prototype, which is then compared with the current design. The comparison is made by testing the functioning of the instrument and the force required to shear the test material.

The paper presents the development of instrumentaria designed to solve ACL lesions using hamstrings (tendons of semitendinosus and m. gracilis - ST / G). The work itself took place in two phases. Part of the first phase was the development of its own instrumentation, including the implant designed to fix hamstrings tendons. The inherent part of the development was the performance of both mechanical and functional tests. The most tested element of the instrumentation was the screw with eye. In the course of its development, mechanical tests of tensile strength were carried out on the individual variants of the solution, and then the rapture of the screw with the eye from animal bone - simulating the function of the product in a real environment. Part of this was the development of methodology and work with new instrumentation. Clinical testing was performed in the second stage and the results of the operations are part of the work. The self-developed ACL lesion reconstruction toolkit is designed to use a graft made up of four strands of the above tendons. In the experimental part of the instrumentation development, the suitability of the implant for clinical use has been demonstrated. The newly developed instrumentation for ACL reconstruction, using the test implant for fixation of the hamstrings...

Author: Bc. Jan Vocásek Thesis title: Analysis of the shoulder girdle injury and therapy of overhead athletes in Czech republic Cíl: The aim of the thesis was to create a literal research for the shoulder girdle injuries of overhead athletes, theoretically to write the anatomical and kinesiological characteristics of the shoulder girdle, to analyze the biomechanics, injury mechanisms in individual overhead sports, rehabilitation treatment and to find out how frequent the injuries of athletes in the Czech Republic follow-up treatment varies from abroad. Methods: For the purpose of this research was established a non-standardized questionnaire, based on literature studied and research questions, and then was distributed to 6 selected physicians dealing with this issue in the Czech Republic, who anonymously filled out questions regarding the shoulder joint injury based on their own clinical experiences. Results: Four of the six hypotheses were confirmed from the data obtained. The number of patients with shoulder girdle injuries in overhead sports in the Czech Republic has risen year- on-year and the most common injury is SLAP lesion. It has also been confirmed that the most common injury is caused by ball overhead sports and on the dominant upper limb. Key words: shoulder girdle, overhead sports,...

Title Comparison between the effectiveness of extracorporeal shockwave therapy (ESWT) and the surgical approach in the treatment of the rotator cuff tendinopathy. Objective The main goal of this research work is comparing the effectiveness of extracorporeal shock wave therapy and the surgical intervention (arthroscopic approach) in the treatment of calcific rotator cuff tendinopathy depending on the outcome measures of the Constant-Murley Score (CMS), and the Visual Analogue Scale (VAS) from the recent scientific publications. Methodology This thesis is systemic (literature) review. The studies which recruited in this research were randomized controlled trials, prospective studies, and retrospective case series studies which written in English language form, and published between the year 2000 to the year 2018. The studies were retrieved from following databases: EMBASE, PubMed, CINAHL, Medline, SpringerLink, ProQuest using different integrations of the key words. The participants in the studies were from both genders and all ages. The type of the pathology which included in this research was chronic calcific rotator cuff tendinopathy. Regarding the intervention types both Radial, and Focused ESWT with low, medium, and high intensities and the arthroscopic interventions were the main types of...
