The Most Cited and Influential Publications Relating to Ice Hockey Since 2000 Focus Primarily on Concussion and Traumatic Brain Injuries.

Purpose: To determine the most frequently cited articles relating to ice hockey since 2000 and conduct a bibliometric analysis of these publications. Methods: The Clarivate Web of Knowledge database was used to gather data and generate a list of publications relating to "ice hockey" on June 20, 2022. Articles were filtered by the total number of citations accrued and were included or excluded on the basis of relevance to ice hockey; no date of publication, language, or journal restrictions. After the 50 most highly cited articles were identified, articles published before the year 2000 were excluded to avoid bias. The information analyzed from each article included author name (first and last), publication year, country of origin, institutional affiliation (of the first and last author), journal name, research design, main research topic, competition level, and the level of evidence. Results: Ultimately, 46 studies were included in this analysis. The total number of citations was 8,267 times with an average of 179.7 citations per article. The most cited article was cited 926 times. The articles came from 5 different countries, with the United States and Canada comprising 27 and 13 articles, respectively. All articles were published in English. The American Journal of Sports Medicine published the greatest number of articles. The most studied topic was concussion/traumatic brain injury (n = 26). Professional hockey was the most studied level of competition (n = 15), while college followed (n = 13). Three institutions, University of Calgary, Dartmouth School of Medicine, and University of North Carolina at Chapel Hill were responsible for 32.6% of the top articles (n = 15). Conclusions: The majority of the most cited articles relating to ice hockey are cohort studies, review articles, and epidemiological studies originating from the United States or Canada. The majority of publications included in the analysis focused on concussion and traumatic brain injury prevalence, identification, diagnosis, outcomes, and prevention, as well as the most studied level of competition was professional, but the greatest number of participants arose from the youth and high school level. Level of Evidence: Level IV, cross-sectional study.

Medical Scribes in an Orthopedic Sports Medicine Clinic Improve Productivity and Physician Well-Being.

Purpose: The purpose of this study is to examine the effects of scribe use on physicians, nurses, and patients in an orthopaedic sports medicine clinic. Methods: Surveys containing validated outcome measures relating to physician well-being and workplace satisfaction, among other variables, were used to assess the influence of medical scribes on clinic function. These surveys were collected for 8 months from all patients, nurses, and orthopaedic surgeons working in one orthopaedic sports medicine clinic. Time during a half-day clinic (i.e., 20 or more patients) was documented by surgeons after the last patient was seen. Results: The average time spent per half day of clinic was 104 minutes on nonscribe days and 25 minutes on scribe days. Additionally, the time spent documenting encounters per half day of clinic was 87 minutes on average without scribes and 26 minutes on average with scribes. The average surgeon single assessment numeric evaluation (SANE) score was 48.1 without scribes, and 89.3 with scribes. The overall assessment of the clinic by nurses was 73.4 out of 100 on average without scribes and 87.7 out of 100 on average with scribes. Patients did not report a significant change in rating of overall experience (4.7/5.0 with scribes and 4.8/5.0 without scribes, (P = .27) or wait time between scheduled appointment time and surgeon arrival (15.1 minutes with scribes and 18.1 minutes without scribes; P = .12). Conclusions: We found the use of scribes in a high-volume orthopaedic sports medicine clinic to have a favorable impact on physicians, nurses, and trainees. The use of a scribe also significantly reduced the time required by surgeons for documentation during clinic and at the end of each clinic day. Patients also reported no significant difference in patient clinic experience scores. Clinical Relevance: Orthopaedic surgeons spend a substantial amount of time on paperwork. The results of this study could provide information on whether the use of a scribe helps to reduce administrative burden on orthopedic surgeons.

A novel meniscofemoral ligament variant intra-substance to the PCL.

While much detail is known about each anatomic structure of the knee and its contributory effect on biomechanics, our understanding is still evolving. In particular, the function of the meniscofemoral ligaments and their anatomical variants have yet to be fully described. In this report, a never-before-described anatomical meniscofemoral ligament variant intra-substance to the PCL is presented. Arthroscopists should be aware of the novel variant as a growing number of studies have demonstrated the biomechanical importance of the meniscofemoral ligaments in protecting the lateral meniscus and supporting the function of the PCL.Level of Evidence: IV.

Can NFL Combine Results be Used to Estimate NFL Defensive Players Longevity?

The National Football League Scouting Combine is an annual event held to evaluate football players. The results of the combine are used to identify talent and player potential. Our study aims to examine the relationship between combine drill performance (e.g., speed, power, agility, explosiveness) and career longevity. We performed a retrospective review of The National Football League combine test results for all defensive players from 2005-2015 to determine the association of each player's combine test results with career longevity. The position that had the most significant associations for 1-year status was linebackers, with weight, 10-yard dash, 20-yard dash, 40-yard dash, broad jump, 3-cone drill, and shuttle being significantly associated with 1-year roster status. The position that had the most significant associations for 5-year status was cornerbacks, with weight, 10-yard dash, 20-yard dash, 40-yard dash, 3-cone drill, and shuttle being significantly associated with 1-year roster status. The least number of significant associations was found for safeties, with no drill being associated with 1-year roster status and only height and shuttle time significantly associated with 5-year career longevity. Our study demonstrates the utility of the combine results to help estimate the career longevity of NFL defensive players.

Dual-Posteromedial Portal Technique for Complex Arthroscopy in the Posterior Knee.

Arthroscopy in the posterior knee continues to improve as new techniques arise. Traditionally, posterior techniques included posteromedial and posterolateral portals. Although frequently used, these techniques do have some limitations. We propose the use of dual posteromedial portals for complex arthroscopy cases to improve access and instrumentation in the posterior knee. Applications include, but are not limited to, resection of tumors or masses in the posterior knee, meniscal posterior horn repair, ramp lesion repair, repair of posterior cruciate ligament avulsions, and use as accessory portals for arthroscopic posterior cruciate ligament reconstruction. We describe a technique for establishing dual posteromedial portals for complex arthroscopy in the posterior knee, specifically in relation to a case of a posterior knee mass biopsy and resection.

Prevalence, Biomechanics, and Pathologies of the Meniscofemoral Ligaments: A Systematic Review.

PURPOSE: To systematically review the literature to examine current understanding of the meniscofemoral ligaments (MFLs), their function, their importance in clinical management, and known anatomical variants. METHODS: A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed, EMBASE, and Cochrane databases. Studies were included if they reported on the biomechanical, radiographic, or arthroscopic evaluation of human MFLs, or if they reported on an anatomical variant. These were then categorized as cadaveric, radiographic, or clinical. Biomechanical, radiographic, patient-reported, and functional outcomes data were recorded. RESULTS: Forty-seven studies were included in the qualitative analysis, and 26 of them were included in the quantitative analysis. Of these, there were 15 cadaveric, 3 arthroscopic, and 9 radiographic studies that reported on the prevalence of MFLs. Overall, when looking at all modalities, the presence of either the anterior or posterior MFL (aMFL, pMFL) has been noted to be 70.8%, with it being the aMFL 17.4% and the pMFL 40.6%. The presence of both ligaments occurs in approximately 17.6% of individuals. Eleven reported on mean MFL length and thickness. When evaluating mean length in both men and women, the aMFL has been reported between 21.6 and 28.3 mm and the pMFL length in this population is between 23.4 and 31.2 mm. Five reported on cross-sectional area. Nine additional papers report anatomical variants. CONCLUSIONS: This review shows that there continues to be a variable incidence of MFLs reported in the literature, but our understanding of their function continues to broaden. A growing number of anatomic and biomechanical studies have demonstrated the importance of the MFLs in supporting knee stability. Specifically, the MFLs serve an important role in protecting the lateral meniscus and augmenting the function of the posterior cruciate ligament. CLINICAL RELEVANCE: Our findings will aid the clinician in both identifying and treating pathologies of the meniscofemoral ligaments.

Multiple flexor tendon pulley ruptures in a division 1 collegiate football player.

Injuries to the hand and digits are common in football players. To our knowledge, there have been no reports on multiple flexor pulley ruptures in football players treated non-operatively through splinting and taping techniques. A 22-year old collegiate defensive lineman sustained an injury resulting in complete disruption of the annular 2, 3, 4, and cruciate 1 and 2 pulleys. The patient was successfully treated with serial custom splints for 12 weeks. Our splinting and taping techniques and timing of these have not been previously described. This case illustrates a successful treatment option in football players with multiple flexor pulley ruptures.

Diagnostic Evaluation of the Knee in the Office Setting Using Small-Bore Needle Arthroscopy.

Arthroscopy is currently the gold standard for diagnosing intra-articular knee pathology. Magnetic resonance imaging (MRI) can be a clinical adjunct for diagnosis; however, it is not without its shortcomings. Although highly accurate, even advanced imaging misdiagnoses the condition in 1 in 14 patients with regard to anterior cruciate ligament pathology. Previous studies have indicated that MRI fails to identify meniscal pathology when one exists in 1 of every 10 cases, and diagnoses pathology when pathology truly does not exist in 1 of every 5 patients. In-office arthroscopy offers an alternative to formal diagnostic arthroscopy, with reduced cost and risk of complications. This is a technique article that discusses the use of small-bore needle arthroscopy in the office setting.
