The blast injury caused a critical soft-tissue defect of the lower leg combined with comminuted fractures of the tibia and fibula. Although indicated, the patient refused the amputation of the lower leg. Initially closed reduction and stabilization by an external fixator, local debridement as well as soft-tissue coverage by a porcine skin were performed at a local field hospital.

These patients underwent three-dimensional CT reconstruction of the knee joint using a medical 3D model. This study employed three distinct methodologies to measure the PCA. The first method involved single-plane 2D CT measurement, which provides a clear assessment of the posterior femoral condyle axis line (PCAL) and the surgical epicondylar axis (sTEA) of the femur. The second method utilized multiplane 2D CT with continuous plane sliding positioning to identify both the PCAL and sTEA when measuring PCA. The third method incorporated a 3D printing model whereby a solid model of the patient's distal femur was fabricated using 3D printing technology. In this approach, the PCAL and sTEA were marked using in vitro Kirschner wires, followed by CT scans of the marked femur. The PCA was subsequently measured based on the positioning of the Kirschner wires, with the PCA obtained from the 3D printed model considered the reference standard.

The goal of surgical therapy is the anatomical reconstruction of the articular surface, while simultaneously restoring axial, length, and rotational alignment, in order to prevent long-term functional impairment and the development of post-traumatic gonarthrosis. A successful treatment is based on comprehensive diagnostics, including radiography, computed tomography, CT angiography in cases with suspected dislocation, and, if necessary, additional magnetic resonance imaging to assess associated ligamentous and meniscal injuries. The ten-segment classification and the three-column model have proven to be effective tools for preoperative planning and for selecting the optimal surgical approach. The concept of stepwise extension of the surgical approach as needed allows complete and generally soft-tissue sparing exposure of the affected joint surfaces. Intraoperative three-dimensional imaging significantly improves reduction control and is associated with greater anatomical accuracy and lower revision rates. Concomitant ligamentous and meniscal lesions should be addressed, either simultaneously or in a staged manner, depending on their relevance for joint stability. While partial meniscal tears may be left untreated in stable situations, displaced or unstable ruptures require (possibly arthroscopically assisted) repair and only rarely (partial) resection. Bony avulsion injuries of ligaments should be included in the fracture fixation, whereas intraligamentous ruptures or high-grade instabilities can be successfully treated with direct suture, augmentation, or secondary reconstruction. In summary, a stepwise extendable surgical approach, in combination with complete articular surface exposure, intraoperative 3D imaging control, and function-oriented management of concomitant injuries, has proven to be an evidence-based strategy to achieve stable, anatomical restoration and optimal long-term functional outcomes.</p>","PeriodicalId":94274,"journal":{"name":"Zeitschrift fur Orthopadie und Unfallchirurgie","volume":" ","pages":"458-468"},"PeriodicalIF":0.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147793849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
