[Evaluation of the Clinical Outcomes of Autologous Chondrocyte Implantation in the Management of Chondral Lesions of the Knee after 10+ Years].

Purpose Of The Study: The authors present the outcomes of more than ten-year clinical follow-up of patients who underwent surgical treatment of deep chondral defect of the knee (medial or lateral condyle). The method of treatment was the implantation of autologous cultured chondrocytes in the form of a solid chondral graft. The aim was also to compare the mid-term and long-term outcomes and to evaluate how the knee condition affects the everyday life and sports activities more than 10 years after surgery.

[Comparison of the Outcomes of Revision Anterior Cruciate Ligament Reconstruction Using Cadaverous BTB Graft with the Outcomes of Primary ACL Reconstruction with Filtering out the Effects of Age and Sex].

PURPOSE OF THE STUDY Evaluation of the success rate of revision ACL reconstruction using the cadaverous BTB allogeneic graft and comparison of the outcomes achieved with the data of patients after the primary ACL reconstruction using the autologous BTB graft with filtering out the potential effect of diversity of the groups of patients as concerns sex and age. MATERIAL AND METHODS The evaluated outcomes of 34 patients operated in the period 2004-2017, i.e.

[Reliability of the Evaluation of MRI Examinations after the Treatment of Chondral Defects in the Knee Joint].

PURPOSE OF THE STUDY This study is a component part of the project focused on cartilage imaging after the treatment of a defect. It aims to compare the evaluation of postoperative status performed by two radiologists with the use of 2D MOCART scoring system and to determine whether this method is a reliable tool for the evaluation of postoperative changes. MATERIAL AND METHODS The study evaluated 78 MRI examinations from 25 patients (one patient had two defects treated), each of whom underwent 3 MRI examinations at 6, 12 and 18 months after surgery.

[Two-Year Results of Modified AMIC Technique for Treatment of Cartilage Defects of the Knee].

PURPOSE OF THE STUDY Damage 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.

[Current Options and Importance of Imaging of the Hyaline Articular Cartilage of the Knee Prior to the Surgery - a Different Perspective of an Orthopaedic Surgeon and a Radiologist].

The authors present an overview of the commonly used techniques and new trends of the cartilage imaging, especially postoperatively, and also discuss the potential of MRI imaging of the cartilage from the perspective of an experienced orthopaedic surgeon. In conclusion, the authors propose possible explanations for the potential discrepancies between the MRI and the arthroscopic findings. Hyaline cartilage damage and subsequent reparation of this tissue is one of the topical issues of orthopaedics and traumatology.
