Acta Chir Orthop Traumatol Cech. 2023; 90(4):233-238 | DOI: 10.55095/achot2023/028 
Purpose of the study A global bibliometric comparison of the level of scientific interest and output in the two research areas hip and knee arthroscopy (H-ASC and K-ASC) was carried out. In addition, the different degrees of publication activity in the countries and institutes performing this research were investigated. Material and methods Publications from 1945-2020 listed in the Web of Science Core Collection were included in the study. Using the web application Science Performance Evaluation (SciPE), quantitative and qualitative aspects were evaluated. Subsequently, the date of publication, author information, and...

Acta Chir Orthop Traumatol Cech. 2023; 90(4):239-250 | DOI: 10.55095/achot2023/029
Purpose of the studyDislocation is one of the most common early complications of total hip arthroplasty (THA). In this manuscript, 20 years of experience with the management of this complication are presented, particularly in relation to the type of instability. Material and Methods In the period between January 1999 and December 2020, at least one dislocation occurred in 157 of 8 286 (1.9%) THA patients, of which 117 dislocations (1.6%) in primary and 40 (3.4%) in revision THAs. Almost all patients were operated on from the anterolateral approach during the follow-up period. The type of dislocation was evaluated using...

Acta Chir Orthop Traumatol Cech. 2023; 90(4):251-258 | DOI: 10.55095/achot2023/030
Purpose of the studyTotal arthroplasty of the first metatarsophalangeal joint is one of the surgical treatment options for patients with advanced hallux rigidus. This study evaluates the pressure changes in the propulsion phase of the gait cycle using dynamic pedobarography after the total arthroplasty of the first metatarsophalangeal joint by Medin PH-Flex and their comparison with the control groups of patients with hallux rigidus and with asymptomatic patients. Material and methods Dynamic pedobarograph was used to evaluate 15 first MTP joint replacements by Medin PH-Flex implants in 12 female patients, the average...

Acta Chir Orthop Traumatol Cech. 2023; 90(4):259-266 | DOI: 10.55095/achot2023/031
Purpose of the Study The current study aimed to investigate the intra- and inter-observer reliability of the Ellman classification system in partial-thickness rotator cuff tears through magnetic resonance imaging (MRI) scans instead of arthroscopic views. Material and Methods Pre-operative MRI scans of 45 patients, with confirmed partial-thickness rotator cuff rupture in previous arthroscopic surgeries (performed by the senior author), were obtained from Picture Archiving and Communication Systems records. The observers (n=8) were asked to categorize MRI scans according to Ellman's classification of location and grade....
The Anti-Inflammatory Effect of miR-140-3p in BMSCs-Exosomes on OsteoarthritisOriginal papers

Acta Chir Orthop Traumatol Cech. 2023; 90(4):267-276 | DOI: 10.55095/achot2023/032
Purpose of the Study Articular cartilage injury is a common disease in daily life, with a high incidence. The aim of this study was to investigate the effect and mechanism of miRNA-140-3p in bone mesenchymal stem cells (BMSCs)-derived exosomes under hypoxia on inflammatory articular chondrocytes. Material and Methods To simulate the pathological status of arthritis, rat chondrocytes were used to establish the osteoarthritis (OA) model by IL-1β (10 μg/ml) as a modulating in vitro, and exosomes were isolated by differential ultra-high speed centrifugation. The cell counting kit-8, wound healing and flow cytometry...
Short-term Outcomes of Touch® Prosthesis for Thumb Carpometacarpal JointOriginal papers

Acta Chir Orthop Traumatol Cech. 2023; 90(4):277-282 | DOI: 10.55095/achot2023/033
Purpose of the study Rhizarthrosis, a degenerative condition of the carpometacarpal joint of the thumb, affects mainly women. Surgical treatment is indicated once the non-operative treatment fails. Thumb carpometacarpal joint total arthroplasty constitutes one of the surgical treatment options. This study aims to evaluate the short-term functional and radiological outcomes of Touch® prosthesis with a minimum follow-up period, namely two years after surgery. Material and methods The study presents the outcomes of a group of 56 endoprostheses implanted in 48 patients. The dual mobility Touch® prosthesis is evaluated....

Acta Chir Orthop Traumatol Cech. 2023; 90(4):283-287 | DOI: 10.55095/achot2023/034
Acute traumatic intervertebral disc herniation of the thoracic spine is a rather rare injury with only a few reported cases to date. In this manuscript, we present a case of a 58-year-old male patient who sustained a car accident-related high-energy trauma, resulting in a disc herniation of the thoracic spine. Furthermore, we also discuss the possible implications of late diagnosis of such condition. The patient was initially referred from the Emergency Department as a case of head contusion with a left upper limb paresis. Due to only minimal bony trauma visible on the initial spine CT scan, the neurological deficit was attributed to the cranial trauma....

Acta Chir Orthop Traumatol Cech. 2023; 90(4):288-290 | DOI: 10.55095/achot2023/035
The spleen is one of the most commonly injured organ in blunt traumas to the chest and abdomen. Splenic injury can be a serious complication of fracture of the left 9th to 11th rib. The authors present a case report of a 65-year-old male patient with a blunt trauma to the left chest and abdomen, diagnosed with multiple left rib fractures, left hemothorax and splenic injury with a small subcapsular hematoma with no signs of active splenic bleeding. Due to hemodynamic instability and a large volume of blood loss via the chest drain, the patient was indicated for emergency left thoracotomy. A perforation in the lower lobe of the...
