The stability of the patellofemoral (PF) joint involves an intricate relationship between muscular forces, soft tissues, trochlear and patellar geometry, and limb alignment. Several anatomic patellar risk factors (APRFs) have been identified including patella alta (Caton Deschamps &gt;1.2; Insall-Salvati &gt;1.2), rotational malalignment (femoral anteversion &gt;30°, knee rotation &gt;10°, and tibial rotation &gt;35°), genu valgum (Valgus: zone 2 or greater), a lateralized tibial tubercle (tibial tubercle-trochlear grove distance &gt;17 mm; tibial tubercle-posterior cruciate ligament distance &gt;21 mm), and trochlear dysplasia. The importance of APRFs is highlighted by their overwhelming association with patellar instability; &gt;80% of patients with patellar instability have at least 1 risk factor. Biomechanically, these risk factors increase lateralizing forces on the patella, increase maltracking (patellar tilt and subluxation), decrease contact area, and increase pressure in the PF joint. In addition, there is greater anisometry of the medial PF ligament reconstruction. Clinically, the presence of APRFs increases the chances of recurrence after a first episode as well as failure rates of medial PF ligament reconstruction. Initially described by Dejour on lateral radiographs, current APRF evaluation includes standard radiographs along with axial slice imaging, with magnetic resonance imaging being more commonly used currently. In some instances, mechanical axis radiographic views and axial computed tomography rotational alignment studies may be indicated. Each risk factor can be assessed independently, as there are good-quality studies defining abnormal thresholds for individual APRF. However, there is a lack of robust clinical data defining use of these thresholds for guiding decisions regarding nonsurgical/surgical treatment, specifically, which factors need to be surgically managed and at what threshold for optimal outcomes. It is important to understand that there is an intricate and complex interaction between risk factors that need to be considered during PF evaluation. Overall, evaluation of APRF is one of the core elements of PF instability management.</div></div>","PeriodicalId":55459,"journal":{"name":"Arthroscopy-The Journal of Arthroscopic and Related Surgery","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Suture augmentation, applied to either ACL reconstruction or to primary repair, introduces a \"safety belt\" synergistically sharing loads acting on the graft or repair. Several biomechanical studies utilizing different autologous grafts for ACL reconstruction, as well as studies on ACL repair, have demonstrated that suture augmentation enhances strength and prevent elongation of the graft or ligament. Suture augmentation can protect the graft-brace integrity under loads of 350N, and reduces cyclic displacement by up to 31% compared to conventional ACL reconstruction using bone-patellar tendon-bone allograft. Perhaps, as above, the greatest advantage of suture augmentation is allowing early rehabilitation. Assuming successful ligamentization of the graft, the graft itself should stabilize the knee joint, thereby diminishing the long-term benefit of suture augmentation. In practice, we utilize suture augmentation to support immediate postoperative mobilization and weight-bearing, enabling safe and early rehabilitation, while minimizing the risk of failure. With regard to the oft-mentioned risk of over-constraint, this is not supported by biomechanical studies or clinical experience. Recent introduction of collagen co-braid sutures for suture augmentation offer two distinct advantages: first, potentially improved biocompatibility, and second, gradual biological integration allowing suture degradation over time.</p>","PeriodicalId":55459,"journal":{"name":"Arthroscopy-The Journal of Arthroscopic and Related Surgery","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142570324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In parallel with the increased publicity that AI has received since the release of large language models (LLMs) like ChatGPT has been an explosion in the number of studies evaluating LLMs' ability to answer hypothetical questions from patients on a variety of conditions. Nevertheless, these studies tend to leave us with the same conclusion: LLMs are generally capable of providing reliable and relevant responses to patient questions but are not without limitations. Given the abundance of studies demonstrating similar outcomes regardless of whether the LLMs are asked to respond to a patient's questions about their diabetes or about their shoulder dislocation, I'm afraid we are at risk of making AI more of a \"shiny object\" than a tool that can be used to change clinical practice and improve patient care. Specifically, we may be getting to a point where a \"publish or perish\" mindset has promoted studies with repetitive methodologies that only confirm well-established theories around the capabilities and limitations of AI and has created a distraction from new use-cases and more meaningful applications for patient care. We are now at a crossroads where we can either remain stuck in the past, repeating old studies' methodologies on a different procedure or injury, or progress by expanding the number and impact of applications these tools have in orthopaedic surgery.
