[Evaluation of the application of hyaluronic acid in postoperative arthroscopy patients with grade II-III gonarthrosis using the WOMAC scale].

Introduction: gonarthrosis is a degenerative disease, whose loss of cartilage causes changes in the adjacent bone and its response produces deformations and attempts at regeneration. In 1934 Meyer and Palmer isolated bovine vitreous humor, a polysaccharide called hyaluronic acid, which has the property of visco-elasticity. Today, multiple procedures performed in orthopedics are known, in order to limit the degenerative process that this entails.

[Clinical and radiographic correlation after anterior cruciate ligament reconstruction].

Unlabelled: The purpose of this work is to correlate the clinical, functional and radiographic results of the anterior cruciate ligament (ACL) reconstruction with the angulation and orientation of the femoral and tibial tunnels.

Introduction: The ACL is one of the most frequently injured articular structures of the knee. The reason for this being that it is the primary limiting structure of anterior tibial translation; its tear causes kinematic alterations and results in long-term degenerative and functional changes.
