Introduction: Posterior-stabilized total knee arthroplasty (TKA) has been widely used since its introduction nearly three decades ago, and long-term follow-up studies have reported satisfactory results. However, mechanical failure due to fracture of the tibial post recently has been described in several reports (1). The possible fracture mechanism was the repeated impingement between the interc...

Purpose  Notchplasty is a complementary surgical procedure often performed during anterior cruciate ligament reconstruction (ACLR) with the aim to widen the intercondylar notch and to avoid graft impingement. The aim of this review was to analyze the current literature evidence concerning the effects of notchplasty on clinical outcome after primary ACLR. Methods  Cochrane Database of Systematic...

ligament (ACL) injury are common injuries and can lead to devastating consequences if not treated appropriately. Their mechanism of injury is similar, namely, a valgus twisting injury as a result of sudden non-contact deceleration. Those at risk also share similar epidemiological and anatomical characteristics; they tend to be female, have ligamentous laxity, and be young, active adults, with d...

REPLACEMENT +*Siggelkow, E; *Labhart, M; *Muenchinger, M; +*Zimmer GmbH, Winterthur, Switzerland [email protected] INTRODUCTION: Total knee replacement (TKR) has a long clinical tradition in orthopedic arthroplasty and is a procedure to reduce pain and increase function in patients with arthritis. Different types of prostheses are available according to the patient’s anatomical and biome...

PURPOSE The aim of this systematic review was to evaluate studies published on anatomic double-bundle anterior cruciate ligament (ACL) reconstruction. METHODS A systematic electronic search was performed by use of the Medline and Embase databases. Studies that were published from January 1995 to April 2009 were included. The selection criteria were studies that reported on a surgical techniqu...

BACKGROUND The success of posterior cruciate ligament reconstruction has varied. The objective of this study was to determine quantitatively and qualitatively the topography and osseous landmarks of the femoral footprints of the anterolateral and posteromedial bundles of the posterior cruciate ligament in order to enhance repair. METHODS Twenty unpaired knees from twenty human cadavers were e...

BACKGROUND Preservation of the Anterior Cruciate Ligament (ACL) remnant is important from the biological point of view as it enhances revascularization, and preserves the proprioceptive function of the graft construct. Additionally, it may have a useful biomechanical function. Double bundle ACL reconstruction has been shown to better replicate the native ACL anatomy and results in better restor...

Retrograde femoral rodding is a technique that has recently been used with increasing frequency for the management of supracondylar and femoral shaft fractures. A review of the literature reveals that this technique may have advantages over other fixation techniques in certain clinical situations. Retrograde femoral rodding allows the surgeon to treat bilateral lower extremity injuries simultan...

myocardial fractional flow reserve (ffr) is a new index of the functional significance of intermediate coronary stenoses that is calculated from pressure measurements made during coronary arteriography. the aim of this study was to evaluate the correlation between non-hyperemic coronary pressure dicrotic notch and fractional flow reserve (ffr). a consecutive of 114 patients (73 men and 41 women...

Anatomic ACL reconstruction is the reasonable approach to restore stability without loss of motion after ACL tear. To mimic the normal ACL like a ribbon, our preferred procedures is the anatomic rectangular tunnel (ART) technique with a bone-patellar tendon-bone (BTB) graft or the anatomic triple bundle (ATB) procedure with a hamstring (HS) tendon graft. It is important to create tunnel apertur...
