BACKGROUND: Treatment for fractures of the tibial plateau is in most cases carried out by stable fixation in order to allow early mobilization. Minimally invasive technologies such as tibioplasty or stabilization by locking plate, bone augmentation and cement filling (CF) have recently been used to treat this type of fracture. The aim of this paper was to determine the mechanical behavior of the tibial plateau by numerically modeling and by quantifying the mechanical effects on the tibia mechanical properties from injury healing...

OBJECTIVE: Angle stable interlocking intramedullary nail (ASIN), a novel technique, has rarely been used for treatment of tibial plateau fractures (TPF). This retrospective study was designed to introduce this novel technique, ASIN, as well as to describe the initial experience and verify the effectiveness when ASIN was used for the management for TPF. METHODS: A cohort of 19 cases with closed TPF aged from 18-70 years with at least 23 months follow-up from November 2008 to September 2013 was analyzed retrospectively...

Instead of extensive dissection of soft tissue around the fracture site, percutaneous techniques have unique advantages in managing displaced fragments, including preservation of soft tissues, less blood loss, lower risk of complications, and earlier functional rehabilitation. However, there are few systematic reviews on the effects of percutaneous reduction and internal fixation (PRIF) for tibial plateau fractures. A systematic search of Cochrane, EMBASE, and MEDLINE databases was performed for all publicly available data in March 2017 regarding the use of PRIF in treating monocondylar tibial plateau fractures...

Background: Fibular collateral ligament (FCL) tears are challenging to diagnose. Left untreated, FCL tears lead to residual ligament instability and increased joint loading on the medial compartment of the knee. Additionally, when a concomitant anterior cruciate ligament (ACL) reconstruction is performed, increased forces on reconstruction grafts occur, which may lead to premature graft failure. Stress radiographs constitute a reliable and validated technique for the objective assessment of a complete grade III FCL tear...

The purpose was to analyze tibial plateau fractures (TPF) by computed tomography (CT) by creating a frequency map (FM). We hypothesized that a FM shows clinically important aspects of involvement that are not expressed in classic classifications. 185 TPF were retrospectively evaluated in this single center study. We created a FM onto an axial template of an intact subarticular tibial plateau and separated the joint surface in 9 areas, counted the frequency of involvement. The FM gives information of location and grade of damage and expressed three major fracture areas in 76%...

BACKGROUND: Impaired bone structure poses a challenge for the treatment of osteoporotic tibial plateau fractures. As knowledge of region-specific structural bone alterations is a prerequisite to achieving successful long-term fixation, the aim of the current study was to characterize tibial plateau bone structure in patients with osteoporosis and the elderly. METHODS: Histomorphometric parameters were assessed by high-resolution peripheral quantitative computed tomography (HR-pQCT) in 21 proximal tibiae from females with postmenopausal osteoporosis (mean age: 84...

PURPOSE: The incidence of wound complications after open reduction with internal fixation (ORIF) of tibial plateau fractures in young patients has been reported to range from approximately 5 to 15%. Reports on wound complication rates in the elderly patients are limited. This study investigates the incidence of post-operative wound complications in elderly patients undergoing ORIF of their tibial plateau fractures. METHODS: A retrospective study was performed within three accredited level 1 trauma centres...

Early soft-tissue coverage is critical for treating traumatic open lower-extremity wounds. As free-flap reconstruction evolves, injuries once thought to be nonreconstructable are being salvaged. Free-tissue transfer is imperative when there is extensive dead space or exposure of vital structures such as bone, tendon, nerves, or blood vessels. We describe 2 cases of lower-extremity crush injuries salvaged with the quad flap. This novel flap consists of parascapular, scapular, serratus, and latissimus dorsi free flaps in combination on one pedicle...

The surgical management of tibial plateau fractures can be technically demanding. In younger patients, the mainstay is fixation with cartilage preservation. In older patients with osteoporotic bone, this method has higher rates of fixation failure; in addition, it requires prolonged bed rest or protected weight bearing, which are major challenges in this group. In contrast, total knee arthroplasty performed acutely for primary treatment of tibial plateau fractures has potential advantages for elderly patients, such as immediate stability, early mobilization, and positive functional outcomes with decreased rates of reoperation...

PURPOSE: Patient-specific instrumentation (PSI) for unicompartmental knee arthroplasty (UKA) has been available for a few years. However, limited literature is available on this subject. Hence, the aim of this cohort study is to evaluate the 2 years' results of our first experiences with the use of PSI in UKA. It is hypothesised that there is no advantage in rate of adverse events and in radiological and functional outcomes in comparison to literature on the conventional method. METHODS: This cohort included 129 knees of 122 patients, operated by one surgeon...

Popliteal artery trauma is uncommon but is associated with a high risk of limb loss depending on the scenario involving blunt or penetrating trauma as well as the severity and extent of injury that has occurred. In our setting there is a significant amount of gang and civilian warfare resulting in Vascular Trauma. There were 32 patients over a decade who sustained traumatic injury to the popliteal artery consisting of 30 males (94%) and 2 females with an age range 16-59 years with a mean of 32. There were 20 cases of penetrating trauma (63%) and 12 cases of blunt trauma (37%)...

INTRODUCTION: Tibial plateau widening in the setting of fracture is an indication for surgical treatment, and restoring width is an important goal of surgery. In order to identify and correct pathological widening, the width of the normal tibial plateau must first be defined. The aim of this study was to establish normative data for the width of the tibial plateau relative to the distal femur to enable surgeons to identify and correct pathological widening in the setting of tibial plateau fracture...

The most widely used medications for the treatment of osteoporosis are currently bisphosphonates and denosumab. Both are antiresorptives, thus targeting the osteoclast and inhibiting bone resorption. Denosumab achieves greater suppression of bone turnover and greater increases of bone mineral density (BMD) at all skeletal sites, both in naïve and pre-treated patients. No superiority on fracture risk reduction has been documented so far. In long-term administration, bisphosphonates reach a plateau in BMD response after 2-3 years, especially at the hip, while BMD increases progressively for as long as denosumab is administered...

BACKGROUND: Posterior plate fixation is biomechanically the strongest fixation method for posterolateral column fracture (PLCF) of the tibial plateau; however, there are inherent deficiencies and risks of a posterior approach. Thus, the 'magic screw' was proposed to enhance fixation stability of the lateral rafting plate used for PLCF. The purpose of this study was to re-examine and compare the stability of different fixation methods for PLCF. METHODS: Synthetic tibiae models were used to simulate posterolateral split fractures...

Orthopaedic surgeons commonly have the misconception that patients with tibial plateau fractures will likely go on to posttraumatic knee arthritis requiring total knee arthroplasty (TKA). In younger patients, osteochondral allograft (OCA) transplantation is an alternative method to address posttraumatic knee arthritis. The purpose of this study was (1) to identify our institutional failure rate following tibial plateau open reduction and internal fixation (ORIF) (failure was defined as conversion to TKA or OCA); (2) to determine if there are patient- or injury-related risk factors predictive of failure; and (3) to characterize differences between patients treated with TKA versus those treated with OCA transplantation...

OBJECTIVES: To compare the strength of fixation of percutaneous screw versus plate/screw fixation in a paired cadaver model of OTA 41-B3 (1) (Schatzker type II) split depression fractures of the lateral tibial plateau. METHODS: Six matched pairs of cadaveric knees were acquired. A OTA 41-B3 (Schatzker type II) split depression fracture was created in all specimens using a standardized method. One specimen from each matched pair of knees was fixed with percutaneous screws, and the other was fixed with a plate/screw construct...

Background: Split fractures of the lateral tibia plateau in young patients with good bone quality are commonly treated using two minimally invasive percutaneous lag screws, followed by unloading of the knee joint. Improved stability could be achieved with the use of a third screw inserted either in the jail-technique fashion or with a triangular support screw configuration. The aim of this study was to investigate under cyclic loading the compliance and endurance of the triangular support fixation in comparison with the standard two lag-screw fixation and the jail technique...

Treatment of tibial plateau fractures associated with anterior cruciate ligament (ACL) injuries can be challenging. Maintaining the joint surface and axis are two main principles for the management of patients with tibial plateau fractures. Herein, we describe a patient with tibial plateau fracture of Schatzker type VI associated with complete ACL rupture. Although in a two-stage reconstruction surgery for treatment of its rupture seem to be accepted by most orthopaedic surgeons in cases of ACL injuries, we treated our patient with ORIF in a one-stage ACL reconstruction surgery...
