Publication Cross-cultural adaptation and validation of the KOOS, JR questionnaire for assessing knee osteoarthritis in Spanish-speaking patients(2023) Guiloff, Rodrigo; Iñiguez, Magaly; Prado, Tomás; Figueroa, Francisco; Olavarría, Nicolás; Carrasco, Eduardo; Ergas, Enrique; Salgado, Martín; Lyman, StephenPurpose The present study aims to translate, adapt and validate a Spanish version of the Knee Injury and OsteoarthritisOutcome Score, Joint Replacement (KOOS, JR), including a reliability and validity analysis in patients with knee osteoar-thritis (OA).Methods This study conducted a prospective validation study following the six stages of the “Guidelines for the Process ofCross-Cultural Adaptation of Self-Report Measures”. Psychometric testing was conducted in patients with knee osteoarthritis.Subjects answered the Spanish KOOS, JR (S-KOOS, JR) and a validated Spanish Oxford Knee Score (S-OKS). Retest wasconducted at 10 days. Acceptability, floor and ceiling effect, internal consistency (Cronbach’s α), reproducibility (mixed-effect model coefficient [MEMC]) and construct validity (Spearman’s correlation; p = 0.05) were assessed.Results Forty-one patients (mean age: 65.6 ± 5.39; 48.8% female) participated in the study. All patients (100%) answeredboth scores during the first assessment and 38 (92.7%) during the second assessment. All patient-reported outcomes measureswere answered completely (100%). The S-KOOS, JR resulted in 100% acceptability when answered. There were no ceilingor floor effects detected. The Cronbach’s α for the S-KOOS, JR was 0.927 and its MEMC was 0.852 (CI 95% 0.636–1.078).The Spearman’s correlation between the S-KOOS, JR and the S-OKS was 0.711 (CI 0.345–0.608; p < 0.001) and 0.870 (CI0.444–0.651; p < 0.001) for the first and second assessments, respectively.Conclusion The S-KOOS, JR has very high internal consistency and reproducibility, with a high correlation with the S-OKS;it is a reliable and valid instrument for characterising Spanish-speaking patients suffering from knee OA.Level of evidence IV.Publication Age influences the efficacy of osteochondral autograft transfer: Promising results for patients under 40(2024) Figueroa, Francisco; Figueroa, David; Calvo, Rafael; Stocker, Esteban; Itriago, Minerva; Nuñez, MarilauraBackground: Previous research using osteochondral autograft transfer (OAT) has shown poorer outcomes with increasing patient age. The aim of this article is to evaluate a cohort of patients that received an OAT and to correlate their clinical results with their age at procedure. Methods: Patients that underwent an OAT to treat an osteochondral (OC) lesion with a minimum 24-month follow-up were included. Patients were categorized into two groups based on their age at procedure (<40 years and ≥40 years). Postoperatively, each patient completed the Knee injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC), and Lysholm scales. Results: 51 patients were included (35<40 years, 16≥40 years). Mean follow-up was 4.2 years (2-7). For patients<40 years, IKDC averaged 80.8 (SD 15.9) versus 71.2 (SD 19.4) in ≥40 years (p=0.03). For patients <40 years, Lysholm averaged 85.9 (SD 10.8) versus 77.0 (SD 21.6) in ≥40 years (p=0.02). For patients<40 years, KOOS averaged 78.3 (SD 11.8) versus 68.9 (SD 18.5) in ≥40 years (p=0.01). There was a 100% sensibility in identifying all the patients with a poor IKDC and Lysholm from 34 years old (AUC 0.76 and 0.8). Conclusions: OAT has better outcomes in patients younger than 40 years compared to patients older than 40 years. Based on the prognostic capacity of age, the ideal candidate for an OAT is a patient younger than 34 years old.
