Graft tensioning is a controversial issue in anterior cruciate ligament reconstruction (ACLR) that has not achieved consensus between peers. The purpose of this study is to determine if after tensioning tendon length and resistance to maximal load changes. We performed an in vitro study with 50 porcine extensors tendons. The first group (P=25) was tensioned(More)
BACKGROUND The main objective of this study was to evaluate the association between the acromial index (AI) and the incidence of recurrent tears of the rotator cuff (RC) in a cohort of patients with full thickness tears who underwent arthroscopic primary repair. METHODS A prognostic study of a prospective case series of 103 patients with full thickness RC(More)
PURPOSE To evaluate integration and maturation of semitendinosus-gracilis (STG) grafts in anterior cruciate ligament (ACL) reconstruction with magnetic resonance imaging (MRI) in patients who underwent ACL reconstruction with STG with and without autologous platelet concentrate (APC). METHODS A randomized single-blinded evaluator prospective study was(More)
BACKGROUND The aim of this study was to evaluate the midterm results and complications of a total shoulder arthroplasty implanted with a metal-backed, bone-ingrowth glenoid component. MATERIALS AND METHODS In total, 62 patients (65 shoulders) diagnosed with primary osteoarthritis were treated with total shoulder arthroplasty with a cementless glenoid(More)
PURPOSE The aim of this study was to describe the clinical outcomes of patients with knee osteoarthritis (OA) treated with arthroscopic surgery, documenting the associated injuries and defining the type of treatment selected for OA patients with different symptoms. HYPOTHESIS Knee arthroscopy is effective for treating patients with symptomatic OA and(More)
The purpose of this study was to evaluate clinical, functional and imaging results of full thickness patella cartilage lesions treated with osteochondral autografts (OCA). We studied a consecutive case series of 10 patients. At follow-up, Lysholm and International Knee Documentation Committee (IKDC) scores were obtained. Magnetic resonance imaging (MRI)(More)
OBJECTIVE The aim of this study was to evaluate the contribution to hyaline cartilage regeneration of the microfracture (MFx) technique plus intraarticular betamethasone (BMS) or platelet-rich plasma (PRP). DESIGN Full-thickness chondral defects of 3 × 6 mm(2) were surgically performed in both femoral condyles of each knee in 13 New Zealand rabbits and(More)
BACKGROUND Surgical treatment with open reduction and internal fixation (ORIF) of displaced middle-third clavicular fractures resulted in shorter complete return to work periods with earlier consolidation documented on computed tomography (CT) scans in this prospective, randomized controlled trial. METHODS The study randomized 76 consecutive patients with(More)
