Tibial plateau fractures have a broad spectrum of presentations, depending on the mechanism and energy trauma. Many classification systems are currently available to describe these injuries. In 1974, Schatzker proposed based two-dimensional representation fracture. His with six-principles types became one most utilized for tibial fractures. More than four decades after this original publication, we revisiting each fracture type in light information made by computed tomography, which today...

Transplantation of fresh osteochondral allografts (OCAs) is an attractive treatment option for symptomatic articular cartilage lesions in young, healthy patients. Because the lack OCA bone integration can be a cause failure, methods speeding and enhancing to mitigate this potential complication are highly desirable.To determine if autogenous marrow aspirate concentrate (BMC) large femoral condylar OCAs would associated with superior radiographic compared nontreated during critical first 6...

Three-dimensional imaging has changed the understanding and management of tibial plateau fractures. In 1970s, Schatzker proposed a classification for fractures, which highlighted morphology six principal types. More recently, this original was complimented by an extended one underscoring importance where split wedge fragment(s) is/are located in three dimensions. The introduced fragment continuity rim as determinants joint stability critical role that plays current manuscript re-emphasizes...

The resection of recurrent malignant pelvic tumors was supported by a commercially available navigation system in three patients. Preoperatively three-dimensional images from the pelvis were obtained computed tomography or magnetic resonance imaging to identify tumor extension. During surgery navigated tools oriented surgeon excise with adequate virtual margins. Navigation helpful for identification one patient presacral mesenchymal chondrosarcoma. In other two patients bone done observation...

To evaluate the union rate of posttraumatic bone defects treated with induced membrane technique.Single-center retrospective case series.Level I trauma center.Thirty-three patients who sustained 34 (19 tibia, 15 femur).Staged management using technique described by Masquelet. After extensive debridement at fracture site, a polymethylmethacrylate (PMMA) spacer was inserted into resulting void. soft tissue recovery, removed, and void, now enveloped an membrane, filled autologous iliac crest...

Complex fractures of the lateral tibial plateau may extend to posterior rim knee and spines. Displaced posterolateral corner result in joint incongruity instability, especially with flexion. Anatomical reduction surface containment are primary goals treatment such cases. Dedicated surgical approaches including dissection peroneal nerve, sometimes association an osteotomy fibular head typically used address these injuries. Some techniques require special positioning patient on operative...

Update This article was updated on April 30, 2020, because of a previous error. On pages 1 and 10, in the byline section author affiliation section, “Augusto de Almeida Armando Teixeira” now reads “Armando Augusto Teixeira.” An erratum has been published: JBJS Essent Surg Tech. 2020 June 2;10(2):e0099ER. Background: Critical-size bone defects are defined as where spontaneous regeneration is not expected without treatment . The characteristics (etiology, location, size, presence infection,...

Abstract No surgical technique recreates native posterior cruciate ligament (PCL) biomechanics. We compared the biomechanics of five different PCL reconstruction techniques versus PCL. Cadaveric knees (n = 20) were randomly assigned to one techniques: Single bundle all-inside arthroscopic inlay, single suspensory fixation, arthroscopic-assisted open onlay (SB-ONL), double inlay (DB-INL), and fixation (DB-SUSP). Each specimen was potted connected a servo-hydraulic load frame for testing in...

Controversy exists regarding double-bundle (DB) versus single-bundle (SB) posterior cruciate ligament (PCL) reconstruction, with differences in multiple variables affecting biomechanical and clinical results. Our objective was to compare immediate postimplantation biomechanics of SB DB reconstructions determine the relative importance restoring both PCL bundles total graft volume. Twenty knees were randomly assigned five techniques (n = 4 knees/technique), performed by three surgeons...

To compare the diagnostic performance of three-dimensional turbo spin-echo (3D TSE) magnetic resonance imaging (MRI) technique with standard two-dimensional (2D protocol at 1.5 T, in detection meniscal and ligament tears.Thirty-eight patients were imaged twice, first a multiplanar 2D TSE MR technique, then 3D both same T MRI scanner. The underwent knee arthroscopy within three days after MRI. Using as reference standard, we determined agreement.For detecting anterior cruciate tears, routine...

The aim of this pilot study was to evaluate the accuracy two different methods navigated retrograde drilling talar lesions. Artificial osteochondral lesions were created in 14 cadaver lower limbs. Two evaluated by one examiner. Navigated Iso-C 3D used seven cadavers and 2D fluoroscopy-based navigation remaining seven. Of lesions, 12 successfully targeted drilling. In both cases inaccurate targeting used, missing 3 mm 5 mm, respectively. mean radiation time increased using (23 s; 22 24)...

Background: Anatomic reconstruction of the posterior calcaneal facet after intra-articular fracture is one critical factors in achieving a good functional result. Intraoperative evaluation reduction and implant placement relies on direct view by standard fluoroscopy. We hypothesized that three-dimensional (3D) fluoroscopy more accurate than conventional fluoroscopy, equivalent to CT for determining screw position fractures. Methods: A Sanders type IIB pattern was created eight embalmed lower...

Abstract Schatzker introduced one of the most used classification systems for tibial plateau fractures, based on plain radiographs. Computed tomography brought to attention importance coronal plane-oriented fractures. The goal our study was determine if addition computed would affect decision making surgeons who usually use assess Image studies 70 patients sustained fractures were uploaded a dedicated homepage. Every patient linked folder which contained two radiographic projections...

Comminuted patellar fractures represent a challenging clinical problem. Treatment aims to restore the integrity of extensor mechanism and congruity patellofemoral joint. Controversy exists regarding ideal fixation method. Metallic constructs aiming convert pulling forces on anterior aspect patella into compression across fracture site are standard care. More recently, low profile plates have been described in management comminuted fractures. The this study were (1) develop novel unstable...

Tibial plateau fractures are joint lesions that require anatomical reduction of surface and functional restoration mechanical axis a lower limb. Patient profile, soft tissue conditions, presence associated injuries the available infrastructure for treatment all contribute to decision making about best these fractures. High-energy usually approached in staged manner respecting principle damage control, primarily targeted maintain limb alignment while resolution unfavorable conditions is...
