Prevalence of radiographic primary hip and knee osteoarthritis in a representative Central European population.

The aim of our study was to determine the radiographic prevalence of hip and knee osteoarthritis and compare our results with prevalence data reported by other studies, as no similar study had been performed in Hungary previously. Our aim was also to investigate the usefulness of the different radiological scoring methods for the definition of osteoarthritis. Patients who earlier reported complaints and gave written consent were asked to participate in a clinical follow-up.

[Prevalence of knee osteoarthritis in Hungary. Study conducted in a representative Hungarian population].

Unlabelled: In an earlier publication, authors have already reported the result of a survey conducted in a representative Hungarian population, where joint complaint prevalence data were presented, including those of the knee joint.

Aims: Following the above mentioned publication, in the current study authors aimed to determine the clinical and radiological prevalence of knee osteoarthritis using internationally accepted scoring methods for evaluation.

Methods: 2422 patients with complaints and consent were invited for a clinical follow up.

Osteochondral integration of multiply incised pure cartilage allograft: repair method of focal chondral defects in a porcine model.

Background: A focal cartilage lesion has limited capacity to heal, and the repair modalities used at present are still unable to provide a universal solution. Pure cartilage graft implantation appears to be a simple option, but it has not been applied widely as cartilage will not reattach easily to the subchondral bone.

Hypothesis: We used a multiple-incision technique (processed chondrograft) to increase cartilage graft surface.

[Legal regulation in the field of tissue engineering].

In the past few years, biotechnology and tissue engineering have developed a great deal. Legislation, however, has not been able to keep pace with the rapid changes in the research and treatment using tissue-engineered products. The authors tried to explore and compare all the regulatory factors concerning cell and tissue engineering in the Hungarian and foreign law.
