Lex ,&nbsp;Jihad Abouali ,&nbsp;Jay Toor","doi":"10.1016/j.jor.2025.03.016","DOIUrl":"10.1016/j.jor.2025.03.016","url":null,"abstract":"&lt;div&gt;&lt;h3&gt;Purpose&lt;/h3&gt;&lt;div&gt;In-Office Needle Arthroscopy (IONA) is an emerging technology that has been primarily studied as a diagnostic tool. Recent evidence shows that it is a cost-effective alternative to hospital- and community-based MRI with comparable accuracy. Although exciting for surgeons and administrators, little is known about patients' perceptions of IONA. Level IV evidence shows that patients with claustrophobia or contra-indications to sedation prefer IONA to MRI for diagnostic purposes. However, no study to date has examined patients' preferences regarding IONA and traditional surgical arthroscopy. Therefore, this study was conceived with the purpose of gathering patients’ perspectives on IONA as an alternative to traditional surgical arthroscopy through semi-structured interviews. A secondary outcome was to determine the real-life financial impact with respect to profit and cost of introducing IONA at an academic mid-sized Canadian hospital.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Method&lt;/h3&gt;&lt;div&gt;All patients undergoing arthroscopic non-ligamentous knee surgery within a three-month period at a mid-sized academic hospital were approached for this study. A trained researcher conducted telephone interviews regarding patient experience with the entire surgical process, including diagnosis and treatment, suffering an injury, referral for MRI and sports surgeon, and booking arthroscopic surgery. Participants were provided information on IONA, including risks and benefits as an alternative to traditional arthroscopy, and were asked about their likelihood of choosing IONA as an alternative to their treatment pathway. Thematic and quantitative analysis was conducted based on interview results, with quantitative analysis conducted using a 5-point Likert scale. Financial analysis was conducted by observing the propensity to choose IONA via patients’ response to the 5-point Likert scale and then modeled for cost effectiveness.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;Twenty-one patients were interviewed. The mean age was 32.3 (SD: 9.8) years old with 12 (57.1 %) females. Mean time from surgery to interview was 10.2 weeks (SD: 11.4). In general, patients’ perceptions of IONA were favorable. When asked how likely they would have been to opt for IONA over traditional arthroscopy, the mean response was “very likely” (4.10 [1.26]). The mean likelihood for males to select IONA was higher than females (4.78 versus 3.58). Common reasons for wanting IONA were to speed up the time between injury and surgery (n = 9), avoiding a general anesthetic/intubation and associated complications (n = 7), and avoiding the fear/anxiety of surgery (n = 6). Most patients listed the lack of primary data on the effectiveness, pain, revision rate, and PROMs as the primary hesitation (n = 6). Financial analysis revealed that IONA would reduce costs by $21,832.66 (p &lt; 0.0001), resulting in an increase in profit of $21,468.80 (p &lt; 0.0001).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusion&lt;/h3&gt;&lt;div&gt;The most si","PeriodicalId":16633,"journal":{"name":"Journal of orthopaedics","volume":"70 ","pages":"Pages 107-112"},"PeriodicalIF":1.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initial failure rate was 23.1% (n = 43) with mechanisms attributed to OCA Bone (n = 15; 34.9%), Meniscus (n = 13; 30.2%), Joint Disease Progress (n = 11; 25.6%), OCA Cartilage (n = 2; 4.7%), or Unknown (n = 2; 4.7%). Risk factors included concurrent ligament reconstruction, ipsilateral osteotomy, and tibiofemoral bipolar + OCAT. However, older age and higher BMI, as well as potential barriers for post-operative adherence should be considered during patient selection.</div></div><div><h3>Conclusions</h3><div>Recent advances have mitigated key risk factors, such that reductions in knee OCAT failure rates with improvements in function, mental health, and quality of life have been more consistently realized.</div></div><div><h3>Level of evidence</h3><div>2, prospective cohort study.</div></div>","PeriodicalId":16633,"journal":{"name":"Journal of orthopaedics","volume":"70 ","pages":"Pages 88-94"},"PeriodicalIF":1.5,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705291","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}
