INTRODUCTIONThe purpose of our study was to evaluate the clinical outcomes in patients at 3-6 years follow-up after primary implantation of RM Pressfit Vitamys cementless elastic cup and cementless Optimys short stem, including bone tissue remodelling around both the components.MATERIAL AND METHODSThe evaluation covered 49 joint replacements in patients who had undergone surgery at our department between 2012 and 2015. The age at the time of primary surgery ranged from 29 to 71 years, with the mean value of 59.2 years. Postoperatively, the position of endoprosthesis, changes in femoroacetabular offset, signs of osseointegration of the implant,...

PURPOSE OF THE STUDYRib fractures represent one of the most common fractures sustained by 10-40% of all patients with blunt chest trauma, their incidence increases with age. In the current literature, however, new indication criteria continue to emerge. The purpose of this study is to assess the indication criteria, the timing of surgery and the use of individual plates in dependence on fracture location in our patients after the chest wall stabilisation in a retrospective analysis.MATERIAL AND METHODSOur group of patients (n = 349) included the patients who were hospitalised in the Trauma Centre of the University Hospital Olomouc from...

Acta Chir Orthop Traumatol Cech. 2020; 87(3):162-166 | DOI: 10.55095/achot2020/027
PURPOSE OF THE STUDYFractures of the scapula are less frequent, with the incidence reported in literature of approximately 1% of all fractures and 3-5% fractures of shoulder. These fractures are predominantly treated non-operatively. Osteosynthesis is indicated in displaced intra-articular fractures and severely displaced extra-articular fractures of the scapular body, its lateral border in particular. Apart from open reposition and osteosynthesis, also minimally invasive osteosynthesis under fluoroscopic and arthroscopic control has recently been used to treat intra-articular fractures of the scapula. The arthroscopy facilitates debridement of...

PURPOSE OF THE STUDYDamage to hyaline cartilage represents a serious problem due to its limited capacity of regeneration. Currently, there are several treatment options available. The purpose of this study is to evaluate the success rate of treatment of chondral and osteochondral defects of the knee joint using the modified AMIC (Autologous Matrix-Induced Chondrogenesis) technique, combining microfractures of the base and the implantation of the type I collagen-based cell-free implant over a two-year period.MATERIAL AND METHODSThe prospective study of the success rate of treatment by the modified AMIC technique included 15 patients (13...

Acta Chir Orthop Traumatol Cech. 2020; 87(3):175-182 | DOI: 10.55095/achot2020/029
PURPOSE OF THE STUDYPeriprosthetic joint infections in total knee arthroplasty (TKA) represent one of the most limiting factors of implantation. Frequency of this complication is up to 2.5% in primary implantation. Revision TKA with the use of DAIR (Debridement, Antibiotics and Implant Retention) procedure is a widely accepted method in treating infection, but the indication criteria have not been clearly defined as yet. The lack of uniformity prevails also with respect to the surgical technique and the importance of respective techniques for successful treatment. The purpose of this study was to evaluate the factors affecting the two-year survival...

PURPOSE OF THE STUDYIn patients older than 40 years of age, treatment of chondral lesions of the knee employing microfractures does not provide satisfactory outcomes. One of the contributing factors may be the age-related lack of sufficient mesenchymal stromal cells able to efficiently migrate into the desired site of the lesion. Concomitant application of mononuclear cells (MNCs) or cultured mesenchymal stem cells (MSCs) isolated from bone marrow and seeded on a 3D scaffold could provide an alternative enhancing therapeutic efficacy in these patients. The aim of our study was to assess two different sources of bone marrow for isolation of progenitor...

INTRODUCTIONThe purpose of the study was to evaluate the injury-treatment time interval in a group of patients with limb bone fractures over the period of one year; and to compare this interval in the most frequent fractures of the upper and lower limb.MATERIAL AND METHODSThe followed-up group of the prospective one-year monocentric study included 3,148 patients treated consecutively for 3,909 fractures. For the purpose of sub-analysis of the injury-treatment time interval in limb bone fractures, excluded from the group were the patients with multiple fractures (520 pts), patients with spinal fractures (356 pts) and pelvic fractures (210...

PURPOSE OF THE STUDYDecline in length of stay is of growing interest for patients, doctors and health insurances. The aim of our study was to assess the safety and length of stay after omission of casting, start of early mobilization and implementation of functional discharge criteria after total elbow arthroplasty (TEA).MATERIAL AND METHODSWe retrospectively reviewed all patients' records who received a Coonrad-Morrey TEA in the period from January 1st, 2011 to December 31st, 2018. From these records, indications, demographic information and complications were derived. Length of stay was calculated from the...

PURPOSE OF THE STUDYThis study investigated whether there was an optimal interval between two operations for total knee arthroplasties in patients with advanced bilateral gonarthrosis scheduled to undergo staged total knee arthroplasty (TKA).MATERIAL AND METHODSA prospective cohort of 219 patients (136 females, 83 males) undergoing staged total knee arthroplasty for the treatment of advanced bilateral gonarthrosis were followed for up to 12 months. The mean was 69.51±5.02 (56-80) years. Patients were categorized into five groups based on the time between the first and second operations; Group I (21-90 days), Group II (91-180 days),...

Acta Chir Orthop Traumatol Cech. 2020; 87(3):210-214 | DOI: 10.55095/achot2020/034
PURPOSE OF THE STUDYTendon injuries continue to be a highly topical issue. Research and clinical activities in this area aim to achieve an optimal repair of the damaged tendon. Such suture is characterised by maximum tensile strength, resistance to gapping at the repair site, preservation of smooth surface, prevention of adhesions and facilitation of fast rehabilitation and active tendon movement. The suture as such is required to show mechanical resistance in particular. Considered optimal is the use of core suture of the tendon in combination with epitendinous suture. The group of researchers has for several years already been exploring new materials....
