The increased incidence of ACL injuries in females is attributed to a combination of anatomical, physiological, and biomechanical factors that influence knee stability. This review comprehensively explores these contributing factors, highlighting gender-specific anatomical differences such as wider pelvis, increased quadriceps (Q) angle, and steeper tibial slopes, all of which predispose females to greater knee valgus during dynamic activities. Furthermore, hormonal influences and greater ligament laxity are discussed as physiological contributors to increased ACL injury risk. Biomechanical factors such as reduced knee flexion, increased knee valgus, and altered muscle activation patterns further amplify the risk of ACL tears in female athletes. Despite extensive research, gaps remain in the understanding of how these factors interact and influence injury susceptibility. This article is focussed on the critical points in the current literature, analyzing key risk factors, and identifying future research directions that can inform more effective prevention strategies. A better understanding of these factors will ultimately contribute to reducing the incidence of ACL injuries among female athletes and improving long-term strength and stability of knee joint.</p>","PeriodicalId":73881,"journal":{"name":"Journal of orthopaedics and sports medicine","volume":"6 4","pages":"203-209"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11542867/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142606765","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}

The rotator cuff is responsible for most of the shoulder motion, hence the tendon-bone interface experiences immense stress making it incredibly prone to failure. Rotator cuff tendon tears can either occur due to trauma or natural degeneration of the rotator cuff. To help mitigate effects of high stress on the rotator cuff tendon-bone interface, the rotator cuff is intrinsically designed to redistribute stress through protective mechanisms, such as the rotator crescent or coronal-transverse force. But when the tear goes through the intrinsic protective mechanisms, the glenohumeral joint is left unstable and thus is no longer capable of its normal range of motion. Location, size, and type of rotator cuff tendon tears are the strongest indicators for interventional therapy. Surgical therapies demonstrate low success rates, as seen by the significantly high recurrence rate of rotator cuff reinjury following initial repair. This is due to extrinsically healing of rotator cuff tendons, instead of the more intrinsic healing, which causes rotator cuff tendons to not undergo the necessary biomechanical remodeling to prevent reinjury leading to a mechanically and functionally inferior healed tendon. In this article, we thoroughly discussed the underlying pathophysiology of rotator cuff tears from onset to repair to healing, demonstrating that rotator cuff tendon healing is an intrinsically flawed process, irrespective of the risk factors, occurrence of rotator cuff tears, or surgical treatment. Rotator cuff healing can only be successful if rotator cuff tendon repair surgery is augmented with biologics to promote a successful intrinsic healing environment.</p>","PeriodicalId":73881,"journal":{"name":"Journal of orthopaedics and sports medicine","volume":"6 4","pages":"231-248"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11580759/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142689624","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}

Two types of technologies, Partial Body Cryotherapy (PBC) or Whole Body Cryotherapy (WBC), are available in the market. This narrative review reports data from trials exploring WBC in Sport and in physical activity with the aim to show limitations and effectiveness in healthy subjects performing sport activity. The systematic search was conducted on the past ten years. The search keywords were \"Whole Body Cryotherapy\" OR \"Cryogenic chamber therapy\" OR \"Cryostimulation\" AND \"Sport\" OR \"Exercise\" OR \"Athlete\" OR \"Physical Activity.\" The sample size, subject’s age and gender, year of publication, duration and temperature of exposition, physical activity and outcomes were extracted. 15 articles met the inclusion criteria. Data on 265 subjects aged between 20 to 56 years were reported. The WBC protocols covered temperatures from -20 to -120 degrees Celsius. Exposure times ranged from 1 minute to 3 minutes. The cryostimulation sessions were coupled to normal daily recreational activities or, in the case of athletes, competitive activities during the competition season. WBC is a safe procedure and no major adverse events neither alteration of vital parameters were reported. The benefits have been found especially in post-exercise DOMS. Since many aspects need to be clarified a research agenda has been produced to answer crucial questions. In conclusion WBC seems to be a useful tool in Sport Medicine. However, further studies are necessary to establish standardized protocols.","PeriodicalId":73881,"journal":{"name":"Journal of orthopaedics and sports medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69349457","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}

Noma has one of the highest mortality rates, estimated at 90%. Noma begins in the oral cavity and it spreads rapidly and destroys bone, muscle, and skin in the orofacial anatomy. The full onset of Noma is preventable and inexpensive to treat at its early stage. However, a significant number of Noma cases do not receive treatment until it is either too late to save their face or, more commonly, their life. With the recommendation to further investigate the beliefs and perceptions of Noma patients to understand their behavior in seeking medical care, the focus in this situation should remain on understanding the underlying causes. This study examined the main reasons Noma survivors initially had for delaying medical care and that eventually motivated them to seek it. Methods: To achieve the objective of the study, a structured and scheduled qualitative interview was used. A total of 46 Noma cases from different geographic areas in Ethiopia were interviewed in March 2023 to describe the main factors that prevent them from seeking timely medical care and ultimately lead them to seek it. The study participants were asked to indicate their main reason for not seeking medical care soon enough. Then they were asked why they finally decided to pursue medical care.","PeriodicalId":73881,"journal":{"name":"Journal of orthopaedics and sports medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69349522","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}

In the second trial, thirteen healthy participants (three women) performed the combined exercise comprising 3 min each for optimal walking (3 km/h), fast walking (5 km/h and 6 km/h for women and men, respectively), squatting, second optimal walking, and ergometer exercise at 30% VO 2peak , which were intermitted by 30 sec. Finally, they performed ergometer exercise at 100% VO 2peak for 1 min followed by 3-min cool-down (0W). Changes (∆) in VO 2 from the resting value and sEMG AMP during exercise were summed throughout the exercise period (Σ∆VO 2 and ΣsEMG AMP ). ΣΔsEMG AMP was positively correlated with ΣΔVO 2 (r=0.68, p=0.011, @250Hz).
