OBJECTIVES The purpose of this study was to clarify the appearance of the reparative tissue on the articular surface and to analyse the properties of the reparative tissue after hemicallotasis osteotomy (HCO) using MRI T1ρ and T2 mapping. METHODS Coronal T1ρ and T2 mapping and three-dimensional gradient-echo images were obtained from 20 subjects with medial knee osteoarthritis. We set the reg...

Chitosan-Hyaluronate hybrid gel (CHHG) is a self-forming thermo-responsive hydrogel. The current study was undertaken in order to assess the effect of CHHG on rat's surgically induced osteoarthritis. Methods. Thirteen rats were included in the study. In all rats weight-bearing was assessed using a Linton Incapacitance tester. All rats underwent bilateral medial partial meniscectomy. Four rats r...

The clinical and radiographic results of 54 knees (52 patients) with a unicondylar knee arthroplasty (UKA) with fixed-all polyethylene bearing implanted for lateral osteoarthritis were studied at 5- to 16-year follow-up (mean, 100.9 months). Four underwent second surgery: 1 conversion to total knee arthroplasty and 3 received UKA in the medial compartment. The mean International Knee Society kn...

We investigated the relationship between the pain experienced by 50 patients with osteoarthritis of the hip and the resting intra-articular pressure of the synovial fluid. We found a significant linear correlation between these factors, greater pain being experienced by patients with higher pressures. In 20 cases we showed that the pressure rises in extension and medial rotation and is least in...

Knee axial deformities associated with medial or lateral compartment osteoarthritis can be reliably addressed with high tibial osteotomies. Different surgical techniques can be successfully used for achieving the correction. Whatever the technique used, accurate patient selection and precise surgical procedure are critical to the success of the operation. The authors believe that proximal tibia...

Among many diseases of the joints, most common is osteoarthritis and, in particular, knee osteoarthritis. Current medicine requires new and improved imaging techniques to assess patients with osteoarthritis, which enable early diagnosis, understanding pathophysiology efficacy ongoing treatment. Scientific data on use magnetic resonance (MRI) as an objective method impact shock wave therapy (SWT...

Background: Varus knee is a common deformity of the joint, which usually accompanied by osteoarthritis, especially medial compartment. High tibial osteotomy good solution for varus transferring load from compartment to more healthy lateral slowing progression osteoarthritis. Objectives: To assess changes joint and ankle orientations after open wedge high osteotomy. Patients Methods: This pros...

Although the association between femoroacetabular impingement and osteoarthritis is established, it is not yet clear which hips have the greatest likelihood to progress rapidly to end-stage disease. We investigated the effect of several radiological parameters, each indicative of a structural aspect of the hip joint, on the progression of osteoarthritis. Pairs of plain anteroposterior pelvic ra...

Post-traumatic osteoarthritis (PTOA) develops following traumatic articular insult.1 One model system used to study the progression and treatment of PTOA is destabilization medial meniscus (DMM) as first described by Glasson et al performed in mini-pigs.2–7Miniature-pigs are less available, more expensive have synovial fluid sampling limitations, limiting availability OA biomarkers compared dom...
