Fixed-bearing versus mobile-bearing total ankle replacement survivorship. A meta-analysis.

Background: Main objective of this research is to know if there is a different survival rate between fixed bearing (FB) and mobile bearing (MB) total ankle replacement (TAR). We hypothesized that there are no differences between the survival rates of both implants.

Methods: A systematic search was performed in PubMed, Cochrane, EMBASE and ClinicalTrials.

Spanish Translation, Cross-Cultural Adaptation, and Validation of the Olerud-Molander Ankle Score (OMAS) for Ankle Fractures.

Background: The aim of this study was to translate and cross-culturally adapt the Olerud-Molander Ankle Score (OMAS) into Spanish and to assess its reliability and validity.

Methods: The translation and adaptation to develop the Spanish version of the OMAS (OMAS-Sp) was performed according to current international guidelines. The OMAS-Sp was administered to 98 patients with a surgically treated ankle fracture, and it was repeated 7-14 days later to assess construct reliability of each question's score and the total score.

Arthroscopic Contribution of Synthetic Graft in Tibiotalocalcaneal Arthroscopic Fusions.

Nonunion is a frequent complication of tibiotalocalcaneal arthrodesis. The risk of nonunion increases significantly for those patients with systemic comorbidities and smokers. The purpose of this article is to show the proper way to supplement our arthroscopic fusion surgeries with biomaterial (peptide-15) graft.

Peripheral nerve injuries in the pediatric population: a review of the literature. Part I: traumatic nerve injuries.

Objective: This article reviews the clinical results that can be obtained after repair of a traumatic peripheral nerve injury in the pediatric population.

Methods: A systematic review of the published literature has been made.

Results: Functional outcome after major nerve injuries is sometimes disappointing in adults.

Peripheral nerve injuries in the pediatric population: a review of the literature. Part II: entrapment neuropathies.

Introduction: Entrapment neuropathies are infrequent in children, and therefore remain unrecognized. The incidence of radial, median, and cubital mononeuropathies are all similar. Despite the rarity of such cases, extensive, albeit scattered, literature has accumulated concerning entrapment neuropathies in children.

Peripheral nerve injuries in the pediatric population: a review of the literature. Part III: peripheral nerve tumors in children.

Introduction: Peripheral nerve tumors type, inciedence and treatment in the pediatric population should be analyzed.

Methods: We have performed an extense literature review of this subject.

Results: incidence and distribution are similar to those observed in adults.

Assessment of regeneration in meniscal lesions by use of mesenchymal stem cells derived from equine bone marrow and adipose tissue.

OBJECTIVE To assess the ability to regenerate an equine meniscus by use of a collagen repair patch (scaffold) seeded with mesenchymal stem cells (MSCs) derived from bone marrow (BM) or adipose tissue (AT). SAMPLE 6 female Hispano-Breton horses between 4 and 7 years of age; MSCs from BM and AT were obtained for the in vitro experiment, and the horses were subsequently used for the in vivo experiment. PROCEDURES Similarities and differences between MSCs derived from BM or AT were investigated in vitro by use of cell culture.

Improved prediction of knee osteoarthritis progression by genetic polymorphisms: the Arthrotest Study.

Objective: The aim of this study was to develop a genetic prognostic tool to predict radiographic progression towards severe disease in primary knee OA (KOA) patients.

Methods: This investigation was a cross-sectional, retrospective, multicentric association study in 595 Spanish KOA patients. Caucasian patients aged ≥40 years at the time of diagnosis of primary KOA of Kellgren-Lawrence grade 2 or 3 were included.

The role of different hyaluronic acids in the articular cartilage of rabbit.

Purpose: To elucidate if the differences found in the physico-chemical and rheological behaviour of Hyaluronic Acids result in different in vivo activity. For this purpose two Hyaluronic Acids (HA), HA-1 and HA-2, with similar molecular weight but different percentage of concentration variation, were compared through an osteoarthritis model.

Methods And Materials: Osteoarthritis was induced in white New Zealand rabbits by anterior cruciate ligament section.
