BACKGROUND Osteochondral knee lesions represent a challenging condition encountered by orthopaedic surgeons. A variety of methods have been developed to repair articular cartilage defects. However, these techniques are limited by donor site morbidity or by the requirement for a staged procedure. PURPOSE To assess the effectiveness of a biomimetic(More)
Patellofemoral joint cartilage lesions are associated with a variety of clinical situations including blunt trauma, lateral patella dislocations, or as a secondary development in the setting of abnormal joint loading. There is a need for more clarity on how to best address these lesions. Most specifically, when is it necessary to surgically treat these(More)
The purpose of this study was to evaluate mid-term follow-up results of medial patellofemoral ligament (MPFL) reconstruction using a bioactive synthetic ligament in the treatment of objective patellofemoral (PF) instability. Sixteen patients (18 knees) presenting with objective PF instability underwent a MPFL reconstruction, isolated or associated with(More)
BACKGROUND Results of anterior cruciate ligament (ACL) reconstruction are traditionally excellent in younger and nonarthritic patients. During the past few decades, people older than 60 years have become more active than ever, with more demanding physical lifestyles. An increase also has been noted in active patients with diagnosed ACL injuries. More(More)
An original technique for the reconstruction of the anterior cruciate ligament is explained. Two bundles are reconstructed using the central third of the patellar tendon and the gracilis tendon, passed through four tunnels but requiring only two interference screws for fixation. Level of evidence V.
INTRODUCTION Patella alta is one of the primary factors of patellofemoral instability and its importance lies in the reduced engagement between patella and trochlea during the early degrees of flexion. The evaluation of patellar height is based on conventional x-rays, CT scan and, more recently, MRI. The objective of this multicentric prospective study is(More)
INTRODUCTION The aim of this study was to define a new index to measure lateral patellar displacement (LPD) using nuclear magnetic resonance imaging (MRI), an axial index of engagement of the patella (AEI) obtained from two different axial MRI views then to validate its use in a prospective series of patients presenting an objective patellar instability(More)
Patellofemoral disorders must be approached through an appropriate process of diagnostic framing, performed using language that is, as far as possible, unequivocal and a validated and organic classification system. At present, the classification proposed by the Lyonnaise school, which fulfills these requirements, is the most complete. This classification(More)
BACKGROUND Cartilage lesions of the patellofemoral joint are a challenging condition. Hyaluronan-based matrix-assisted autologous chondrocyte transplantation (MACT) has been shown to offer a significant improvement in the short term but has a tendency to worsen at midterm follow-up. HYPOTHESIS Patients treated with MACT for lesions of the articular(More)
Although tuberculosis (TB) is not a common disease in industrialized countries, it remains a common and endemic illness in developing countries.1 Every year, approximately 10.4million infected people develop active disease, resulting in almost 1.4 million deaths annually.2 Although the majority of newly diagnosed cases have pulmonary TB, a considerable(More)
