Patients with stage II of the knee osteoarthritis most likely benefit from the intra-articular injections of autologous adipose tissue-from 2 years of follow-up studies.
Knee osteoarthritis (OA) is a common, chronic, progressive and degenerative disease which affects patients' quality of life and may cause disability and social isolation. OA is a huge economic burden for the patient and a large strain for the whole healthcare system. Articular cartilage has a small potential to repair, with progressively more clinicians emphasizing cellular therapy. Subcutaneous fat tissue in human body is a large reservoir of mesenchymal stem cells (MSCs) and is been harvested in minimally invasive, simple procedure. The purpose of this study was to define a specific group of patients with knee osteoarthritis, who are the most likely to benefit from the treatment with intra-articular injection of an autologous adipose tissue (AAT). ⋯ The main conclusion of this study is that the patients with stage II of the knee OA with normal BMI are were most likely to benefit from IA injection of AAT, in contrast to the patients with stage IV, who will not beware not satisfied with the effectiveness of this kind of treatment. There were no adverse events reported at the donor site as well as in the treated knee joints.

Three-dimensional cortical and trabecular bone microstructure of the proximal ulna.
The three-dimensional (3D) microstructure of the cortical and trabecular bone of the proximal ulna has not yet been described by means of high-resolution 3D imaging. An improved characterization can provide a better understanding of their relative contribution to resist impact load. The aim of this study is to describe the proximal ulna bone microstructure using micro-computed tomography (micro-CT) and relate it to gross morphology and function. ⋯ N.A.

Impact of stem profile on the revisability and the need for osteotomy in well-fixed cemented revision total knee arthroplasty implants.
While re-revision total knee arthroplasty (ReRTKA) steadily increases, the ease and bone-sparing removal of RTKA implants is gaining more and more in importance. Biomechanical data suggest that cemented conical stems can be removed significantly easier than cylindrical stems. However, no clinical evidence exists supporting this observation. Aim of this study was to compare the revisability and need for osteotomy (OT) between removals of well-fixed cemented conical vs. cylindrical RTKA stems. ⋯ Well-fixed cemented conical stems may be revision friendlier with less demands on OT and shorter overall surgery time than cemented cylindrical stems.

Management of comminuted inferior patellar pole fractures with cerclage-wire-augmented separate vertical wiring: a retrospective clinical study.
Comminuted inferior patellar pole fractures are challenging injuries and require effective treatment due to the extension mechanism of the knee. This study aims to evaluate the outcome of above fractures treated with a modified technique of cerclage-wire-augmented separate vertical wiring (SVW) with cerclage wiring passed through the proximal patella. ⋯ The cerclage-wire-augmented SVW with cerclage wiring passed through the proximal patella appears to be a safe and simple technique which can effectively treat the comminuted inferior patellar pole fractures.

Tricortical iliac crest graft as a salvageable option in the reconstruction of comminuted posterior wall acetabular fractures: our experience from a level 1 trauma centre.
Comminuted fractures of the posterior acetabular wall, pose a significant challenge in the reduction and fixation of the fracture fragments and usually result in dubious functional outcomes. Primary reconstruction of the severely comminuted posterior wall using the autologous tricortical iliac crest graft has shown promising results, especially in fractures not amenable for anatomical reduction and fixation. Thus, the present study analyses the functional and radiological outcomes of severely comminuted posterior wall acetabular fractures, primarily reconstructed with an autologous tricortical iliac crest graft. ⋯ Primary reconstruction of the comminuted posterior wall acetabulum fractures is a potential alternative and salvageable option with favourable outcomes. However, it ought to be considered in severely comminuted fractures where anatomical reduction and internal fixation is not feasible.
