PURPOSE OF THE STUDY Our study aimed to assess the mid-term outcomes and complications with the ICON hip resurfacing system and to carry out a detailed analysis of pitfalls and risks associated with pairing the bearing surfaces of metal-on-metal hip implants. MATERIAL AND METHODS A total of 52 hip joints were assessed in 43 patients who received the ICON hip resurfacing system at our department between 2009 and 2013. The cohort included 34 men and 9 women.

In some types of dislocations, Rockwood type III in particular, the indication for surgical treatment as such is relative. There are numerous techniques and implants available for the reconstruction of AC joint.

The aim was to compare the surgical technique with respect to the clinical outcomes within 3 years postoperatively. MATERIAL AND METHODS The clinical evaluation of revision anterior cruciate ligament reconstructions performed at our department in 2002-2017 was carried out.

Methods: A retrospective study evaluating the results of osteosynthesis in patients with distal radius fractures type 2R3C according to AO classification, operated until December 2018. The ORIF method with volar locking plates (LCP) was used in 54 patients, and closed reduction with ligamentotaxis using external fixation (EF) was used in 33 patients.
INTRODUCTION The 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 METHODS The 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.

PURPOSE OF STUDY Osteochondritis dissecans (OCHD) is an increasingly diagnosed disease among adolescent patients. It is a condition affecting subchondral bone and the lining cartilage. If left untreated, it can cause destruction of cartilage of the affected joint leading to early development of arthrosis.

PURPOSE OF THE STUDY Hip arthroscopy is a widely used method of treatment of hip pathology. It is a technically demanding procedure for which accurate indication is critical. The indication criteria, however, are not yet fully supported by long term results of large patient groups in recent literature.

INTRODUCTION The purpose of our paper is to evaluate the mid-term to long-term results and to confirm the basic criteria of a high-quality revision implant: safe bridging of bone defects, achievement of reliable primary fixation of revision acetabular cup, achievement of good secondary stability with documentable osteointegration of cup and demonstration of remodelling of transplanted bone tissue in the area of defects and in spaces between the implant ribs. MATERIAL AND METHODS Altogether 36 patients (38 cups) were evaluated who had undergone revision hip arthroplasty in the period from 2004 to 2010. The mean follow-up was 8.

The postoperative functionality of the hip endoprosthesis is closely related to proper physiotherapy. A good range of motion, sufficient pain reduction and minimum disruption to the muscle tissues are conditions allowing the patients to perform individualized muscle strengthening exercises and to exercise the newly gained mobility, following practice sessions during the early postoperative period still in hospital.

Purpose Of The Study: Treatment for tears of the anterior cruciate ligament (ACL) in paediatric patients has been a long-discussed issue because of complications associated with ligament reconstruction in the presence of growth plates. Various fixation materials and their efficiency as well as ACL techniques are still under investigation. The aim of our study was to find an optimal strategy of treating acute intra-articular ACL injury in childhood.

Methods: The results of 31 patients that underwent revision THA between 2004 and 2008 are presented. The mean follow-up interval was 7.

Purpose Of The Study: Revision total hip arthroplasty is a demanding surgical procedure. It involves a massive loss of acetabular bone stock associated with primary implant removal, and a complicated revision cup fixation in the highly damaged surrounding bone. The authors describe the use of a novel oblong acetabular cup, type TC (Trč-Cingr), for replacement of a loose acetabular component.

Both autologous chondrocyte-seeded scaffolds and non-seeded scaffolds were implanted into two defects located in the non-weight-bearing zone of the femoral trochlea (defect A was located more distally and medially, defect B was located more proximally and laterally). Control defects were left untreated.

Purpose Of The Study: The authors present the results of surgical treatment of talar dome cartilage defects. They used the transplantation of autologous cultured chondrocytes in the form of a solid chondral graft.
Material And Methods: Patients with chondral lesions categorized as grades II to IV by the Anderson classification or as grades II to IV by the Berndt and Harty classification were indicated for this treatment.
Treatment of the multiple myeloma has developed rapidly during the last years. Introduction of autologous transplantation in the ninetieth of the previous century radically prolonged the period of survival. New types of drugs influencing the metabolism of myeloma cells and their adhesion to neighbouring tissues brought promising improvement of the therapy results.

Purpose Of The Study: The aim of this study was to present the results of treatment of deep chondral defects of the patella by transplantation of a solid chondral graft formed by autologous cultured chondrocytes.
Material And Methods: Indications for autologous chondrocyte implantation most frequently included acute trauma to the knee, particularly the patella, which resulted in a severe focal cartilage defect. The lesions were assessed on the basis of the Bessette and Hunter classification preoperatively, and on the Outerbridge classification during arthroscopy.
