Even if pivot-shift (PS) test has been clinically used to specifically detect anterior cruciate ligament (ACL) injury, the main problem in using this combined test has been yet associated with the difficulty of clearly quantifying its outcome. The goal of this study was to describe an original non-invasive methodology used to quantify PS test, highlighting(More)
PURPOSE To prospectively evaluate the mosaicplasty technique for treatment of femoral condyle cartilage lesions (Outerbridge grade IV) less than 2.5 cm2 in homogeneous group of young active patients. TYPE OF STUDY Case series. METHODS Thirty-seven patients (10 female, 27 male; mean age, 29.5 years) with full-thickness knee chondral lesions were treated(More)
Lachman, drawer, and pivot-shift (PS) tests are important in the assessment of ACL reconstruction. The goal of this work was to analyze the reliability of the PS test using a navigation system, identifying a set of new quantitative parameters and evaluating their clinical relevance. Eighteen patients that underwent anatomic double-bundle ACL reconstruction(More)
Combinations of intra- and extra-articular procedures have been proposed for anterior cruciate ligament reconstruction with the aim of achieving an optimal control of translational and rotational knee laxities. Recently, the need for better reproducing the structural and functional behavior of the native anterior cruciate ligament led to the definition of(More)
We describe an arthroscopic surgical technique for tissue engineered cartilage grafting. A three-dimensional hyaluronic acid support is used for autologous chondrocyte culturing. The technique reduces morbidity of classic autologous implant and avoids open surgery and the use of a periosteal flap. The procedure includes the advantages of arthroscopic(More)
BACKGROUND This study describes a novel method for accurate evaluations of knee kinematics during arthroscopic reconstructions of anterior cruciate ligament (ACL). METHODS Quantitative evaluation of knee stability was estimated by experimental validation on 30 volunteers and by statistical analysis of test repeatability. RESULTS Proposed method present(More)
This study reports on 13 patients (mean age: 31 years) with a femoral condyle defect >1.5 cm2 who underwent treatment with an osteochondral graft of the same size obtained from the superior aspect of the lateral condyle, preserving the patellar groove. Mean follow-up was 61.5 months (range: 13-141 months). Twelve results were rated clinically as(More)
The authors compare the clinical and radiographic outcome in patients with comparable bilateral recurrent patellar dislocation treated surgically on only one side, to clarify the appropriateness of the surgical indication. Sixteen patients were evaluated at an average follow-up of 30 years (20–45); all had been treated by the Roux technique. The results on(More)
The pivot-shift phenomenon has been identified to be one of the essential signs of functional anterior cruciate ligament (ACL) insufficiency. However, the pivot-shift test remains a surgeon-subjective examination, lacking a general recognized quantitative measurement. The goal of the present study was to validate the use of an inertial sensor for(More)
BACKGROUND The purpose of this study was to investigate about the reliability of measuring antero-posterior laxity within-subjects for in-vivo studies using a navigation system. METHODS The analysis was performed by enroling 60 patients undergoing anterior cruciate ligament ACL reconstruction, and assessing AP laxity during the Lachman and drawer tests.(More)
