The Banff Patellar Instability Instrument: validity and reliability of an Indonesian version.

BACKGROUND: The Banff Patellar Instability Instrument (BPII) is a valuable scoring tool for assessing patellofemoral instability in patients suffering from patellofemoral pain syndrome (PFPS). The BPII 2.0 is a shortened version of the BPII. However, there is no Indonesian edition of BPII 2.0 that has been validated. This study aimed to determine the validity and reliability of the Indonesian version of the BPII 2.0. MATERIALS AND METHODS: This was a cross-sectional study that used a forward-backward translation protocol to create an Indonesian version of the BPII 2.0. Thirty patients with PFPS were given the questionnaires. The questionnaire's validity was evaluated by analyzing the correlation between score of each subscale and the overall score to the Indonesian version of the Kujala score using Pearson correlation coefficient, while the reliability was evaluated by measuring the internal consistency (Cronbach α) and test-retest reliability (intraclass correlation coefficient). RESULTS: The Indonesian version of BPII 2.0 and the Indonesian version of Kujala score had a strong Pearson correlation coefficient for construct validity. For all subscales, Cronbach α was 0.90-0.98, indicating adequate internal consistency. The test-retest reliability was high, with intraclass correlation coefficient ranging from 0.89 to 0.98 for all subscales. There was no difference in the Indonesian version of BPII 2.0 response between the first and second administration of the questionnaire which was taken 7 days afterward. CONCLUSION: The Indonesian version of BPII 2.0 was determined to be valid and reliable and is therefore an objective instrument to evaluate patellofemoral instability in patients with PFPS in the Indonesian population.

The direct anterior approach in total hip arthroplasty: Publication trends of Asian countries on PubMed.

BACKGROUND: Total hip replacement (THR) is one of the most successful surgical treatment for advanced hip osteoarthritis. Some surgical approaches for THR have been established, one of it is Direct Anterior Approach (DAA), which is a relatively new and less commonly used, especially in Asian countries. This review aims to consolidate information from PubMed on the direct anterior approach (DAA) for total hip replacement (THR) in Asian countries. PURPOSE: To collect and consolidate information from PubMed on the total hip replacement (THR) using the direct anterior approach (DAA) in Asian countries. METHODS: A search on the PubMed was done for DAA for THR. There were 461 search results about the DAA for THR publications obtained in total, and 51 articles meet the criteria were analyzed for details. The details include top countries publishing the topics, number of publications per year, top 5 journal publishing the DAA for THR topics, top 5 first authors publishing the articles on this topic, and top 5 author on all position published this topic. RESULTS: The Journal of Arthroplasty was the leading publisher on this topic, with 10 articles published. Author Yasuhiro Homma, Tomonori Baba, and Kazuhiro Oinuma published the most number with 9 articles as one of the authors. Japan is the leading country for the publication on this topic with 34 published journals in total. CONCLUSION: The number of published articles in Asian country per year is still inconsistent, with one year without any publication on this topic. Searching the data on the DAA for THR in PubMed bestow useful information about good sources of publication on this topic.
