Aim of the study: To investigate the prognostic significance of radiologic criteria used in decision-making for extra- articular resections and oncological outcomes of these procedures.
Forty-two patients (M/F:28/14), who underwent extraarticular resection between 1998-2023, were retrospectively analyzed. Most common site was knee with 24 (57.1%) patients. Mean age was 36.7 (5-77) years, and mean follow- up was 44.7 (1-295) months. Most common pathology was osteosarcoma (18 pts, 42.9%) and 33 (78.6%) were operated for bone tumors. Tumor size was larger than 10 centimeters in 25 (59.5%). Pathological (intraarticular) fractures were detected in 3 (7.1%). Thirty-nine (92.9%) patients had a positive imaging finding of articular involvement. Site-
independent imaging findings were as follows: effusion in 22 (52.4%), transarticular skip metastasis 2 (4.8%), articular cartilage destruction 15 (35.7%), capsular insertion destruction 3 (7.1%), synovial contrast enhancement 6(14.3%) and bone marrow edema 17 (40.5%). Intraarticular tumor involvement was confirmed in pathology in only 29 (69.0%). Local recurrence was observed in 7 (16.7%) and metastasis developed in 15 (35.7%). While significant correlations were determined among certain parameters, results mainly suggest articular cartilage destruction, synovial contrast enhancement, and pathological (intraarticular) fracture as the universal indicators for extraarticular resections for all anatomical sites. Further studies with larger cohorts are needed to investigate the actual impact of histology, neoadjuvant treatment, imaging findings and resection technique on outcomes. Retrospective multidisciplinary assessment of radiological and histopathological findings is essential to evaluate the accuracy of surgical decision-making.
