[Combined PCL ligament bracing and ACL reconstruction in acute knee dislocation (Schenck IV) - The Hamburg Approach : Video article].
Stepwise reconstruction of knee stability and physiological kinematics in acute knee dislocation. ⋯ Ligament bracing of both cruciate ligaments is an established treatment technique in acute knee dislocations and has been proven to achieve good to excellent clinical results. In an ongoing clinical study primary ACL reconstruction as a modified treatment approach indicated superior stability in a 12-month follow-up in patients with acute knee dislocations.

Posttraumatic reconstruction of the neurocranium and viscerocranium is an essential part of modern oral and maxillofacial surgery, in addition to oncological surgery, surgery of congenital craniofacial deformities and dental surgery. Due to the complex anatomy of the facial skull and significant esthetic and functional demands on its reconstruction, reconstructive trauma surgery in this area places the highest demands on the surgeon. This is all the more true if definitive craniomaxillofacial surgical treatment can sometimes only be performed with considerable delays for the benefit of other life-threatening injuries. ⋯ In combination with intraoperative three-dimensional imaging, these methods result in a treatment pathway tailored to the individual patient, which is directly checked for quality at every step and thus ensures the best possible result for the patient. The use of these technologies extends far beyond the original indications in the area of orbital reconstruction and restoration of bony defects with simple geometry, such as skull defects. Nowadays, even the most complex pan-facial fractures can be restored esthetically and functionally by means of digitalized preliminary planning and individualized skull, orbital and zygomatic implants as well as total temporomandibular joint prostheses.

From a reconstructive viewpoint, injuries of the hand are particularly challenging. They are often associated with exposed tendons, bones, nerves and vessels, whereas little skin and soft tissue reserves are available for coverage. Functional and esthetic requirements necessitate a differentiated approach, depending on the location and extent of the defect. This article gives an overview of reconstruction techniques and flap surgery on the hand for various defect sizes and locations.

The treatment of patella fractures is technically demanding. Although the radiological results are mostly satisfactory, this often does not correspond to the subjective assessment of the patients. The classical treatment with tension band wiring with K‑wires has several complications. Fixed-angle plate osteosynthesis seems to be biomechanically advantageous. ⋯ The standard of care for patella fractures in Germany largely corresponds to the updated S2e guidelines. Tension band wiring is still the treatment of choice. Further (long-term) clinical studies are needed to verify the advantages of fixed-angle plates.

The success of a surgical procedure is significantly influenced by several critical factors. The safety of the patient is the primary goal. ⋯ Trauma surgery poses a particular challenge to preoperative preparation, especially due to urgent surgical interventions. Here, a standardized and evidence-based preoperative evaluation ensures a successful treatment of the patient.
