Results evaluation of the use of intra-articular sodium hyaluronate in the post-operative knee arthroscopy.

Objective: to evaluate the efficacy of hyaluronic acid in the post-operative of knee arthroscopy.

Methods: we have evaluated 49 patients undergoing arthroscopic procedure with the use of intra-articular hyaluronic acid (Group 1) and 49 patients undergoing arthroscopic procedure without the use of hyaluronic acid (Group 2). Patients were evaluated based on the Visual Analogue Scale, household analgesia, assessment of the Range of Motion with a goniometer, and the Lysholm questionnaire.

Cemented, cementless or hybrid fixation options in total knee arthroplasty for osteoarthritis and other non-traumatic diseases.

Background: It is not clear which fixation of total knee arthroplasty obtains the best clinical, functional and radiographic results in people with osteoarthritis and other non-traumatic diseases, such as rheumatoid arthritis.

Objectives: To assess the benefits and harms of cemented, cementless and hybrid knee prostheses fixation techniques in participants with primary osteoarthritis (osteoarthritis following trauma was not included) and other non-traumatic diseases, such as rheumatoid arthritis.

Search Methods: We searched CENTRAL (2011, issue 10), MEDLINE via PubMed, EMBASE, Current Controlled Trials, LILACS, The Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus, Health Technology Assessment Database and the Database of Abstracts of Reviews of Effectiveness, all from implementation to October 2011, along with handsearches of high-yield journals and reference lists of articles.

RANDOMIZED PROSPECTIVE STUDY COMPARING TRANSVERSE AND EXTRACORTICAL FIXATION IN ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION.

Objective: This study had the objective of prospectively comparing transverse fixation (Cross-Pin™) with extracortical fixation (EZLoc™) for the femur, in surgical reconstruction of the anterior cruciate ligament, from a clinical, biomechanical and functional point of view.

Methods: Between April 2007 and November 2009, 50 patients with acute or chronic anterior cruciate ligament injuries underwent arthroscopic reconstruction using the homologous flexor tendons (gracilis and semitendinosus). Randomization of the femoral fixation method was done by means of a draw at the time of the procedure.

SURGICAL TREATMENT OF OSTEOCHONDRAL LESIONS OF THE KNEE BY MEANS OF MOSAICPLASTY.

Objective: To evaluate the functional results from the technique of mosaicplasty, in the knees of patients with osteochondral lesions.

Methods: Between August 1999 and March 2005, 27 patients underwent mosaicplasty on their knees. Twenty-one were male and six were female.
