RESUMO

Background: The Patient Acceptable Symptom State (PASS) cutoff is the value on a patient-reported outcome measure beyond which patients consider themselves to be "feeling well." There are limited data regarding the PASS threshold for non-English versions of the International Knee Documentation Committee-Subjective Knee Form (IKDC-SKF). Purpose: To establish the PASS cutoff for the Thai version of the IKDC-SKF for patients undergoing primary anterior cruciate ligament reconstruction (ACLR) and to identify factors to achieve PASS after surgery. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Included in this study were patients aged 18 to 50 years who had undergone primary unilateral ACLR between January 2016 and February 2020. After enrollment, patients completed the Thai IKDC-SKF and answered the anchor question for determining the PASS. Results: Questionnaires were sent to 321 patients, of whom 173 (53.9%) responded. The vast majority (156 patients; 90.2%) considered themselves to have achieved the PASS. This group of patients had significantly higher IKDC scores than did those who did not have an acceptable symptom state (79.6 ± 14.2 vs 60.7 ± 16.5; P < .001). The receiver operating characteristic curve of the IKDC score for predicting the PASS had an area under the curve of 0.82 (95% CI, 0.72-0.91). The optimum PASS cutoff of the Thai IKDC-SKF was a score of 74.2 (sensitivity, 0.72; specificity, 0.82). Factors that provided favorable odds for achieving the PASS were the use of a hamstring tendon autograft (odds ratio, 4.1; 95% CI, 1.5-20.6) and the absence of a patellofemoral chondral lesion (odds ratio, 3.8; 95% CI, 1.03-14.1). Conclusion: For patients undergoing ACLR, the cutoff for the PASS of the Thai version of the IKDC-SKF was a score of 74.2. Two surgery-related factors provided favorable odds for achieving the PASS: the use of a hamstring tendon autograft and the absence of a patellofemoral chondral lesion.

RESUMO

OBJECTIVES: The aims of this paper were: (i) to examine the intra-observer and inter-observer reliability of the shaft-condylar angle (SCA) and the lateral capitellohumeral angle (LCHA); (ii) to study the influence of experience level on the inter-observer and intra-observer reliability; and (iii) to determine the influence of the the age of the patients on reliability. METHOD: A retrospective cohort study was conducted. The study reviewed 81 elbow radiographs. The patients were aged between 2 and 13 years. All the images taken between 2000 and 2017 were independently measured by a senior pediatric orthopaedic surgeon, a pediatric orthopaedic surgeon, a pediatric orthopaedic fellow, an orthopaedic chief resident, a general practitioner, and a pediatric orthopaedic research assistant. Measurement was performed two times within a 2-week interval. Inexperienced observers (general practitioner and research assistant) were supervised by senior pediatric orthopaedic surgeons for at least 30 radiographs before performing the measurement. Inclusion criteria were as follows: (i) age 2-13 years; and (ii) no previous elbow fracture. EXCLUSION CRITERIA: elbow radiographs do not show true lateral view. The intraclass correlation coefficient (ICC) was used to calculate the reliability. RESULTS: The mean values of SCA and LCHA were 43° and 48°, respectively. For SCA, intra-observer reliability was excellent (ICC = 0.85) for one observer, good (range = 0.73-0.76) for three observers, and moderate (0.59) for one observer. Inter-observer reliability was moderate (0.48, 0.58), whereas the reliability categorized by age group showed excellent agreement (0.88-0.94). For LCHA, intra-observer reliability was excellent (0.84-0.89) for three observers and good (0.66-0.80) for two observers. Inter-observer reliability was moderate (0.44-0.45). Conversely, the reliability classified by age group showed excellent agreement (0.83-0.91). CONCLUSION: Intra-observer reliability for LCHA and SCA were excellent to good for most observers. Inter-observer reliability was moderate for LCHA and SCA. Reliability classified by age group showed excellent to good agreement. Reliability was influenced by the level of experience, especially for non-medical staff.
