In musculoskeletal sarcomas, medical care prioritizes somatic aspects. The primary objective was to assess the impact of a musculoskeletal sarcoma diagnosis on anxiety, depression, and health-related quality of life (HRQoL). Secondary objectives included analyzing the one-year evolution of these variables and the predominant coping profile. Methods A prospective multicenter study with a concurrent control group (116 cases with musculoskeletal sarcomas and 67 controls with benign tumors) was conducted. The HADS and GAD-7 scales were administered to assess depression and anxiety, the QLQ-C30 to evaluate HRQoL, and the CERQ to assess coping strategies, with reassessment in the cases group one year after diagnosis. Outcomes were compared between groups, along with their evolution and the influence of epidemiological, demographic, sociolabor, oncological, functional (MSTS), and health-related variables. Results At diagnosis, cases showed higher prevalence of anxiety (64.7% vs. 40.3%; p = 0.005) and poorer HRQoL (62.1 ± 21.0 vs. 69.4 ± 22.8; p = 0.019) than controls, with no differences in depression. Anxiety and depression were associated with tumor stage (p = 0.01), increasing in advanced stages. In the cases group, anxiety significantly decreased after one year (β = -1.51; 95% CI: -2.38 to -0.63; p = 0.001).

The secondary objective is to assess the surgical relevance of these findings in TKA. Methods It is a multicentric cross-sectional observational study. Preoperative CT-scans of 318 patients from a Spanish cohort were analysed to determine AA-MA, PCA-TEA and LDFA. Then, femoral implant positioning was simulated as 5° of valgus from the AA and 3° of external rotation from the PCA. For each patient, this simulated positioning was compared to the theoretical mechanical alignment target. Finally, the native femoral JLO (LDFA) of each patient was compared to the mechanical alignment target (90°). Results Mean AA-MA relationship was 6.0° ± 0.9°, mean PCA-TEA angle was 3.1° ± 1.8° and mean native LDFA was 87.3° ± 2.9°. Positioning the femoral component systematically at 5° of valgus from the AA and 3° of external rotation from the PCA would result in 74.7% of implants being placed in varus and 46.1% in internal rotation from the TEA. Moreover, mechanically alignment would produce a more varus femoral JLO than the native LDFA in 78.1% of patients. Conclusions There is considerable variability in femoral anatomy within the osteoarthritic Spanish population. The 6.7% of patients had AA-MA values outside the 5-7° range. The 41.8% of patients showed PCA-TEA angles smaller than 2° or greater than 4°. The 30.6% of LDFA were outside the 85-90° interval.

Although several clinical tests are used for meniscal pathology, most were developed for general meniscal lesions rather than specifically for medial meniscus posterior root tears (MMPRT). Evidence on root-specific physical examination signs remains limited. Recently, the Akmese manoeuvre has been introduced as a non-invasive diagnostic tool, assessing pain or tenderness during physical examination. This study aimed to determine the accuracy of the Akmese sign for the clinical diagnosis of MMPRT. Methods This prospective cohort diagnostic study included patients aged 18-55 years scheduled for arthroscopic surgery following a clinical diagnosis of medial meniscus injury between January 2022 and July 2023. Diagnostic performance metrics, including sensitivity, specificity, positive and negative predictive values (PPV, NPV), and likelihood ratios (LR+, LR-), were calculated, using arthroscopy as the reference standard. The interobserver reliability of the Akmese manoeuvre was assessed using the kappa coefficient. Results A total of 201 individuals met the eligibility criteria, with a mean age of 38.4 ± 9.8 years. The Akmese sign was positive in 26 patients, and MMPRT was confirmed by arthroscopy in 28 patients. The Akmese sign demonstrated a sensitivity of 85.7%, specificity of 98.8%, PPV of 92.3%, NPV of 97.7%, LR+ of 74.1, and a LR- of 0.15. Conclusion In this selected surgical population, the Akmese manoeuvre showed promising diagnostic performance and very good interobserver reliability for identifying MMPRT. The sign may be useful as an adjunctive clinical tool to support preoperative suspicion, targeted MRI review, and surgical planning, but it should not be considered a replacement for MRI or arthroscopic assessment.</p>","PeriodicalId":39664,"journal":{"name":"Revista Espanola de Cirugia Ortopedica y Traumatologia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149229040","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}
