INTRODUCTION Accurate implantation of the prosthesis components is a prognostic factor for long-term total knee arthroplasty survival as it reduces wear and loosening failure. Computer-assisted navigation systems have proved to produce accurate bone cuts orthogonal to the mechanical axis. Proper rotational alignment of the femoral component is one of the(More)
INTRODUCTION The importance of a dysplastic trochlea as a component of patellar instability has long been recognized. An original trochleoplasty technique consisting in retro-trochlear recession wedge osteotomy was described by Goutallier et al. The aim is not to fashion a groove but to reduce the bump without modifying patellofemoral congruence. PATIENTS(More)
INTRODUCTION The incidence of associated vascular lesions in biligamentous cruciate injuries of the knee ranges from 16 to 64%, with a mean rate of 30%. Treatment of ischemic vascular lesions associated with ligaments injury is well established, comprising emergency arterial vascular repair, most of the times combined to external fixation. In the absence of(More)
Septic arthritis develops after less than 1% of all arthroscopy procedures. The clinical symptoms may resemble those seen after uncomplicated arthroscopy, raising diagnostic challenges. The diagnosis rests on emergent joint aspiration with microscopic smear examination and prolonged culturing on specific media. Urgent therapeutic measures must be taken,(More)
INTRODUCTION Various surgical techniques have been described to set the rotational alignment of the tibial baseplate during total knee arthroplasty. The self-positioning method ("self-adjustment") aligns the tibial implant according to the rotational alignment of the femoral component which is used as a reference after performing repeated knee(More)
PURPOSE Symptomatic horizontal meniscal tears in young patients are a singular entity. The extent of the lesion is often large, without any injury to the knee. The meniscal tissue might be degenerative. However, a complete resection of the lesion would result in a subtotal meniscectomy. The purpose of this study was to consider the use of a meniscal repair(More)
INTRODUCTION Discoid medial meniscus is a rare abnormality, with incidence estimated at 0.12%. The present study describes this congenital abnormality anatomically and reports clinical results in four symptomatic cases managed by surgery. MATERIALS AND METHOD A retrospective study included three patients (2 female, 1 male), one of whom had bilateral(More)
The aim of this study was to analyze first intraoperative alignment and reason to abandon the use of patient-specific instrumentation using intraoperative CAS measurement, secondly assess by postoperative CT analysis if CI, based on preoperative 3D-MRI data, improved postoperative component positioning (including femoral rotation) and lower limb alignment(More)
PURPOSE The purpose of this study was to assess the fusion rate on CT examinations and to correlate clinically the functional result with the degree of bone fusion in the subtalar joint after posterior arthroscopic subtalar arthrodesis (PASTA). METHODS Fourteen cases, from 36 to 84 years old, were retrospectively followed-up for a minimum of one year(More)
BACKGROUND Meniscal substitutes have been suggested for the treatment of knee pain after partial meniscectomy. However, despite the partial nature of the initial meniscectomy, secondary extrusion of the substitute is common. The primary objective of this study was to evaluate morphological outcomes of meniscal substitute implantation and their potential(More)
