Probiotic Effect of Streptococcus dentisani on Oral Pathogens: An In Vitro Study.

Probiotics, including Streptococcus dentisani, have been proposed as an alternative to re-establish the ecology of the oral cavity and inhibit the formation of pathogenic biofilms. The main objective of this work was to assess the probiotic ability of S. dentisani against Streptococcus mutans, Streptococcus mitis, and Candida albicans biofilms. The ability of the strains to form a monospecies biofilm and the probiotic potential of S. dentisani using the competition, exclusion, and displacement strategies were determined. All strains were moderate biofilm producers. The ability of S. dentisani to compete with and exclude S. mutans and S. mitis during biofilm formation was not significant. However, S. dentisani significantly reduced pathologic streptococcal biofilms using the displacement strategy. Also S. dentisani reduced the formation of the C. albicans biofilm mainly through competition and displacement. In vitro, S. dentisani exhibited probiotic potential to reduce the formation of potentially pathogenic biofilms. Further investigation is required to understand the biofilm-inhibiting mechanisms exhibited by this probiotic strain.

Assessment of Polydopamine to Reduce Streptococcus mutans Adhesion to a Dental Polymer.

Bacterial adhesion to the surface of materials is the first step in biofilm formation, which will lead to conditions that may compromise the health status of patients. Recently, polydopamine (PDA) has been proposed as an antibacterial material. Therefore, the objective of the current work was to assess and compare the adhesion of Streptococcus mutans to the surface of poly(methyl methacrylate) (PMMA) discs that were modified using PDA following a biomimetic approach versus smooth PDA-coated PMMA surfaces. In addition, an assessment of the growth inhibition by PDA was performed. PMMA discs were manufactured and polished; soft lithography, using the topography from the Crocosmia aurea leaf, was used to modify their surface. PDA was used to smooth-coat PMMA discs by dip-coating. The growth inhibition was measured using an inhibition halo. The surfaces were characterized by means of atomic force microscopy (AFM), the contact angle (CA), and Fourier-transform infrared spectroscopy (FTIR). Polydopamine exhibited a significant antibacterial effect when used directly on the S. mutans planktonic cells, but such an effect was not as strong when modifying the PMMA surfaces. These results open the possibility of using polydopamine to reduce the adhesion and growth of S. mutans, which might have important consequences in the dental field.

Design and Implementation of a Digitally Enabled Care Pathway to Improve Management of Depression in a Large Health Care System: Protocol for the Implementation of a Patient Care Platform.

BACKGROUND: Major depressive disorder (MDD) is a serious public health concern worldwide. A treatment approach that incorporates measurement-based care (MBC) and shared decision-making between patients with MDD and their providers may foster patient engagement and improve clinical outcomes. While digital tools such as mobile apps show promise for expanding health interventions, these apps are rarely integrated into clinical practice. OBJECTIVE: The primary objective of this ongoing study is to determine whether implementation of a digital tool-the Pathway Platform-in primary care improves adherence to MBC practices; here, we present the study methods. METHODS: This large-scale, real-world implementation study is based on a pilot study of an earlier iteration of a mobile app (the Pathway app) that confirmed the feasibility of using the app in patients with MDD and showed a positive trend in patient engagement in the app arm. In addition, a user-centered design approach that included qualitative assessments from patients and providers was used to improve understanding of the patient journey and care team workflows. User feedback highlighted the need for enhanced features, education modules, and real-time data sharing via integration with the electronic health record. The current iteration of the Platform includes the newest version of the Pathway app, education modules for both patients and providers, and real-time patient-level data sharing with the electronic health record. The study takes place in primary care sites within the Advocate Aurora Health system in Illinois and includes adult patients with MDD who were recently prescribed monotherapy antidepressant medication (defined as a new start, medication switch, or dose change in the past 3 months). Clinical performance and selected patient outcomes will be compared before and after the implementation of the Platform. RESULTS: Patient recruitment was completed in July 2022, with initial results expected in mid-2023. CONCLUSIONS: This study will provide useful insights into real-world integration of a digital platform within a large health system. The methods presented here highlight the unique user-centric development of the Pathway Platform, which has resulted in an enhanced digital tool with the potential to foster MBC and shared decision-making, improve patient-provider communication, and ultimately lead to optimized treatment outcomes for patients with MDD.

Chemical, Radiometric and Mechanical Characterization of Commercial Polymeric Films for Greenhouse Applications.

In the agricultural sector, companies involved in the production of plastic greenhouses are currently searching for a suitable covering adapted for every climate in the world. For this purpose, this research work has determined the chemical, radiometric and mechanical properties of 53 polymeric films samples from Europe and South America. The chemical tests carried out with these samples were elemental analysis (C, H and N) and FT-IR spectrometry. The radiometric properties here studied were the transmission, absorption and reflection coefficients along the spectrum between 300 and 1100 nm. For the mechanical properties, tensile strength, tear strength and dart impact strength, tests were carried out. Finally, all these data were collected, and a multivariate statistical analysis was carried out using the SPSS statistical to group the samples into statistical groups adapted to specific climatic regions. The elemental analysis and FT-IR spectrometry allowed group the samples into nine groups. The samples were grouped according to their chemical (elemental analysis), radiometric and mechanical properties by multivariate analysis. The dendrogram separated five very different groups in terms of number of samples. These groups have specific chemical, radiometric and mechanical characteristics that separate them from the rest. These groups make it possible to narrow down the applications and correlate with the radiometric properties to see in which geographical area of the world they are most effective in increasing yields and achieving higher quality production.

Is it necessary to add the eluate testing to the direct antiglobulin test to improve the detection of maternal erythrocyte alloantibodies?

BACKGROUND: The screening of umbilical cord blood samples by the Direct Antiglobulin Test (DAT) is the reference tool for the identification of maternal erythrocyte alloantibodies present in erythrocytes; however, its diagnostic usefulness is controversial. OBJECTIVE: To evaluate the diagnostic validity, safety, and efficiency of the eluate testing (detection of antibody in erythrocyte eluates by the Indirect Antiglobulin Test/IAT) in cord blood samples for detection of maternal erythrocyte alloantibodies in comparison with the DAT. MATERIALS AND METHODS: Evaluation study of diagnostic tests. DAT and eluate testing were performed in 306 cord blood samples from neonates born to mothers admitted at Clínica Somer in Rionegro, Colombia; then, antibodies present in the eluates were identified with erythrocyte panels. Percentage of positive results by DAT and IAT were compared with the Pearson's chi-square test and the agreement between both assays with the Cohen's kappa coefficient. The diagnostic sensitivity, specificity, safety, and efficiency of the eluate testing were calculated, taking into account the use of DAT as an imperfect reference test. RESULTS: The DAT detected alloantibodies in 6.21% of samples and the eluate testing in 14.1 %; the strength of agreement between both tests was moderate (k = 0.56) due to 25 discrepancies. The eluate testing showed sensitivity and specificity of 98.83 % and 92.31 % respectively, and a negative predictive value of 99.9 %. The diagnostic efficiency was sufficient for detection of maternal erythrocyte alloantibodies. The antibodies identified in the erythrocyte eluates were anti-A or anti-B (79.5 %), anti-D (136%), anti-C (2,3%), and anti-Fya (2,3%). CONCLUSION: The eluate testing in cord blood samples is a valid, safe, and efficient test for the diagnosis of maternal erythrocyte alloantibodies.

Anterior open bite and its relationship with dental arch dimensions and tongue position during swallowing and phonation in individuals aged 8-16 years: A retrospective case-control study.

OBJECTIVE: To determine the relationship between AOB and factors such as dental arch dimensions and tongue position during swallowing and phonation. MATERIAL AND METHODS: A case-control study was performed in two groups: 132 children with Anterior Open Bite (AOB) and 132 with normal vertical overbite (NVO), aged 8-16 years selected from the records taken by a previous study from five public schools. Dental arch dimensions were assessed through digitalized study models. Swallowing was evaluated using the Payne technique, and phoniatric assessment included an adaptation of the articulation test used to describe phonemes. STATISTICAL ANALYSIS: Chi-Square or Fisher's exact test for comparisons between qualitative variables and the Mann Whitney or T-student were applied to compare the dental arch dimensions according to bite type. A logistic regression model was applied to control the effect of confusion between independent variables and to describe its simultaneous effect on the type of bite. RESULTS: Intercanine, interpremolar and intermolar widths showed higher values in AOB patients with a mean deviation (MD) of 0.536 (P=0.031), 0.60 (P=0.043) and 1.15, (P<0.001) respectively. Distortions caused by tongue interposition and thrust, tongue protrusion during swallowing, mandibular arch intermolar width, total maxillary arch length, maxillary arch perimeter, and posterior arch depth accounted for 64.6% of AOB and allowed for correct predictions in 83.8% of the cases observed in the study population. CONCLUSIONS: A significant association between tongue position and function, as well as alterations such as tongue interposition and thrust during swallowing and phonation in individuals with AOB, were observed. There is a relationship between AOB and the presence of a wider mandibular arch and a narrower, longer, and deeper maxillary arch.

The Difference in Medial Meniscal Extrusion between Non-Weight-Bearing and Weight-Bearing Positions in People with and without Medial Compartment Knee Osteoarthritis.

BACKGROUND: Medial meniscal extrusion (MME) has been correlated with medial meniscal injury and progression of medial knee osteoarthritis (OA). OBJECTIVE: To examine the difference in MME between non-weight-bearing (supine) and weight-bearing (standing) positions in patients with and without medial knee OA. Determine the correlation between body mass index (BMI), Kellgren-Lawrence (KL) grade, Knee Osteoarthritis Outcome Score (KOOS), and MME. DESIGN: Prospective. SETTING: Tertiary institution PM&R Department. PARTICIPANTS: Forty five participants (29 female, 16 male), 24 with healthy knees and 21 with OA. METHODS OR INTERVENTIONS: A single physician sonographer measured supine and standing MME with ultrasound (US) on each participant. The physician was blinded to all measurements. BMI was recorded on all participants. KL grades and KOOS questionnaires were obtained for the OA group. MAIN OUTCOME MEASURES: MME in supine and standing positions, change in MME from supine to standing, BMI, KL grade, and KOOS subscale scores. RESULTS: MME increased .52 mm from supine to standing (P < .001). MME was greater in the OA group in both the supine (P = .002) and standing (P < .001) positions. Increasing BMI was moderately correlated with increasing MME (supine P = .001, standing <.001). Increasing age was correlated with increasing MME (supine P = .012, standing P = .002). Increasing KL grade (from 1 to 4) was correlated with increasing MME (supine P = .015, standing = .006). There was a small-to-moderate correlation between KOOS activities of daily living (ADL) subscale score and change in MME from supine to standing (P = .035). The change in MME from supine to standing positions had a small-to-moderate correlation (P = .035) with KOOS ADL subscale score alone but did not correlate with any of the other KOOS subscale scores or KOOS total scores. Receiver operating characteristic curve analysis suggested a standing MME value of 4.2 mm provides a positive likelihood ratio of 6.02 for knee OA. CONCLUSIONS: MME is greater in those with OA and with weight-bearing. MME correlates with BMI, age, KL grade, and the KOOS ADL subscale score. Finally, standing MME of 4.2 mm yielded a higher positive likelihood ratio to differentiate between healthy knees and those with medial compartment OA than the previously reported value of 3.0 mm.

Arthroscopic Decompression of a Malunited Infrafoveal Femoral Head Fracture: A Case Report.

CASE: A patient presented with a traumatic posterior wall fracture and small femoral head fracture. He initially underwent open reduction and internal fixation to treat the posterior wall fracture. The femoral head fracture was left alone because of its small size and lack of joint incongruity. At 1 year postoperatively, the patient reported pain due to malunion of the femoral head fragment, which was treated arthroscopically. Treatment resulted in significant pain relief sustained at the 6-year follow-up. CONCLUSION: Symptomatic femoral head fractures malunited to the femoral neck are rare complications. Arthroscopy may offer a viable treatment approach for select patients with this condition.

BIRTH OF HEALTHY NEONATE FOLLOWING PREIMPLANTATION GENETIC DIAGNOSIS IN A MOTHER WITH MOSAIC TURNER SYNDROME. CASE REPORT AND REVIEW OF THE LITERATURE.

OBJECTIVE: To report the case of a patient with mosaic Turner syndrome who underwent assisted reproduction treatment with preimplantation genetic testing for aneuploidy and gave birth to a healthy baby girl with normal karyotype; and to conduct a review of the literature on the usefulness of preimplantation genetic diagnosis in women with Turner syndrome. METHODS: A case of a 27 year-old woman diagnosed with mosaic Turner syndrome and secondary altered ovarian reserve, seen in a referral center for infertility management in Medellín, Colombia. The patient underwent in vitro fertilization followed by pre-implantation genetic testing to prevent transmission of Turner syndrome to her progeny. A literature search was conducted in the Medline via PubMed, Clinical Key, OVID, Embase, Lilacs, SciELO and Oxford Journals databases using the following terms: "Turner Syndrome," "Mosaic Turner," "Preimplantation Genetic Screening," "Preimplantation Genetic Testing," "Preimplantation Genetic Diagnosis," "Pregnancy," "Successful pregnancy." Inclusion criteria were case series and case reports, cohort studies and review articles published between January 1980 and June 2017 that included women with Turner syndrome achieving pregnancy by means of in vitro fertilization techniques with their own oocytes and who had undergone embryo biopsy for preimplantation genetic diagnosis. The search was limited to articles in Spanish and English. RESULTS: one study met the inclusion criteria. Both in this report and in our case, patients with mosaic Turner syndrome underwent several cycles of intracytoplasmic sperm injection (ICSI) with their own eggs, then performed embryonic biopsy for preimplantation genetic analysis using different techniques. In both cases, euploid embryos were transferred to the uterus with the subsequent birth of healthy girls with normal karyotype. CONCLUSIONS: Patients with mosaic Turner syndrome could benefit from preimplantation biopsy and genetic analysis to prevent transmission of the genetic defect to their progeny.

Ultrasound Assessment of Weight-Bearing and Non-Weight-Bearing Meniscal Extrusion: A Reliability Study.

BACKGROUND: Ultrasound has become a useful instrument in evaluating musculoskeletal pathology. Recent studies suggest that ultrasound imaging of weight-bearing menisci may enhance the assessment of knee pathology, such as osteoarthritis (OA) and meniscal injuries. OBJECTIVE: The primary aim of this study was to determine the intrarater and interrater reliability of ultrasound measurements of medial meniscal extrusion (MME) after a brief training session. DESIGN: Prospective reliability study. SETTING: Physical medicine and rehabilitation (PM&R) department within a tertiary care institution. PARTICIPANTS: Forty-five participants (29 female, 16 male) were recruited to serve as models, 24 of whom had healthy knees and 21 of whom had radiographically confirmed medial compartment knee OA. Three physician sonographers (1 = experienced, 1 = sports medicine fellow, 1 = post-graduate year [PGY]-4 PM&R resident) were recruited to serve as operators. METHODS OR INTERVENTIONS: Operators received a brief training session on identifying and measuring MME. All operators measured bilateral MME in each model in the standing and supine positions on two separate days. Operators were blinded to all measurements. MAIN OUTCOME MEASUREMENTS: Primary outcomes were inter- and intrarater intraclass correlation coefficients (ICCs) of MME measurements among operators with different levels of ultrasound experience. RESULTS: Supine MME intrarater reliability ICCs were 0.927, 0.885, and 0.780 for the experienced physician, sports medicine fellow, and PGY-4 operators, respectively. Standing MME intrarater reliability ICCs were 0.941, 0.902, and 0.824 for the experienced physician, sports medicine fellow, and PGY-4 operators, respectively. Interrater reliability ICCs were 0.896 and 0.842 for supine and standing measurements, respectively. There was a statistically significant increase in intrarater reliability with experience between the PGY-4 resident and experienced physician operators. CONCLUSIONS: Operators with different levels of ultrasound experience demonstrated good MME measurement intra- and interrater reliabilities in both supine and standing positions.

Exertional Rhabdomyolysis: A Retrospective Population-based Study.

PURPOSE: This study aimed to evaluate the incidence and characteristics of exertional rhabdomyolysis (ER) in a population-based cohort. METHODS: A retrospective cohort study was performed in Olmsted County, Minnesota, from 2003 to 2015. Incident ER cases were ascertained through the Rochester Epidemiology Project medical record linkage system through electronic searches of the International Classification of Diseases, Ninth Revision, codes and clinical note text. Population incidence rate was calculated using the corresponding Rochester Epidemiology Project census populations specific to calendar year and sex. Descriptive statistics were used. RESULTS: Of the 430 patients, 431 cases met the inclusion criteria for rhabdomyolysis; 4.9% of cases (n = 20; males n = 18; Caucasian n = 17) were ER, with one recurrence. There were no deaths secondary to ER. The age- and sex-adjusted incidence rate of ER was 1.06 ± 0.24 (95% confidence interval = 0.59-1.52) per 100,000 person-years. Endurance activity (n = 7), manual labor (n = 5), and weight lifting (n = 4) were common causes. Complications included kidney injury (n = 5), mild electrolyte abnormalities (n = 10), elevated transaminases (n = 12), and minor electrocardiographic abnormalities (n = 4). A majority of patients were hospitalized (n = 16) for a median of 2 d, had mild abnormalities in renal and liver function and electrolytes, and were discharged without sequelae. CONCLUSION: ER in the civilian population occurs at a much lower incidence than the military population. The most common causes were endurance exercise, manual labor, and weight lifting. The majority of cases were treated conservatively with intravenous fluid resuscitation during a brief hospital stay, and all were discharged without sequela. Only one case of recurrence occurred in this cohort, indicating the recurrence rate was low.

Lineamientos de política pública para la gestión del agua en el municipio de Filandia-Quindío / Public policy guidelines for the management of water in the Municipality of Filandia, Quindio

El presente artículo presenta de manera detallada los resultados de la investigación sobre una propuesta de lineamientos de política pública para el municipio de Filandia-Quindío. El trabajo tuvo como objetivo general proponer lineamientos de política pública para la gestión del agua en el municipio de Filandia, para lo cual se estableció como pregunta de investigación ¿fueron las acciones de la administración pública municipal, departamental y de la autoridad ambiental para la gestión del agua en el municipio de Filandia durante el periodo 2008-2015 beneficiosas para el interés general de la población y de los ecosistemas estratégicos en el ciclo del agua? La metodología que se usó fue tipo cualitativa, se buscó y analizó información primaria y secundaria, mediante técnicas documentales y grupo focal. Los resultados obtenidos son la caracterización y diagnóstico de políticas públicas tendientes a la gestión del agua y la elaboración de cuatro lineamientos de política pública para la gestión del agua en el municipio de Filandia. Como conclusiones se tiene que hubo acciones, pero fueron poco efectivas evidenciado por las problemáticas existentes; no hay armonización de políticas en el orden nacional, departamental y municipal; insuficientes predios para la conservación; potencial hídrico manifestado en el abastecimiento de agua a varias poblaciones vecinas y la necesidad de los lineamientos como insumo para la gestión del agua.

This paper presents in detail the results of the research on a proposal of public policy for the Municipality of Filandia, Quindio. The objective of the research was to propose public policy guidelines for water management in the Municipality of Filandia, for which a research question was established as follows: Were the actions of the municipal, and the departmental administration and of the environmental authority beneficial for the general interest of the population and of the strategic ecosystems in the water cycle for the management of water in the Municipality of Filandia during the period 2008-2015? The methodology used was qualitative and primary and secondary information using documentary techniques and focus group was sought and analyzed. The results obtained are the characterization and diagnosis of public policies aimed at the management of water and the elaboration of four public policy guidelines for water management in the Municipality of Filandia. It can be concluded that there were actions, but they were ineffective which is evidenced by the existing problems: there is no harmonization of policies at the national, departmental and municipal order; there are insufficient properties for conservation; water potential manifested in the supply of water to various neighboring populations; and the need for guidelines as an input for the management of water.

Youth Sport-Related Concussions: Perceived and Measured Baseline Knowledge of Concussions Among Community Coaches, Athletes, and Parents.

OBJECTIVE: To assess concussion knowledge of athletes, coaches, and parents/guardians in a community setting and to understand trends/gaps in knowledge among subgroups to tailor efforts toward creating educational interventions. PARTICIPANTS AND METHODS: This prospective cross-sectional study involved 262 individuals (142 [55%] female): 115 athletes participating in noncontact and contact sports (ages 13-19 years), 15 coaches, and 132 parents. Recruitment occurred from August 30, 2015, through August 30, 2016, at 3 local high schools. Participants completed a questionnaire developed by the investigators to assess concussion experience and basic knowledge. RESULTS: Females, health care employees, and parents showed stronger concern for potential long-term sequelae of concussion, whereas athletes were most concerned about not being able to return to sport. Those with higher perceived concussion knowledge were slightly older (median age, 42.5 vs 33 years), more educated (college or higher: 42 [70%] vs 100 [50%]), and more likely to be health care workers (22 [37.9%] vs 34 [17.7%]) and scored higher on knowledge questions (average correct: 75.5% vs 60%). Most participants could identify potential concussion sequelae, but only 86 (34.3%) identified a concussion as a brain injury. Of the subgroups, coaches scored highest on knowledge questions. Those with a concussion history tended to consider themselves more knowledgeable but were also less concerned about sequelae. Overall, those with a concussion history scored slightly higher on knowledge questions (average correct: 69.8% vs 61.9%). Participants involved in contact sports were more likely to have had a concussion vs those in noncontact sports (57 [26%] vs 4 [10.3%]). CONCLUSION: Significant differences in perceived and actual concussion knowledge across different subgroups of study participants involved in high school sports were identified.

Quetiapine-induced hypertriglyceridaemia causing acute pancreatitis.

Second-generation antipsychotics have well-known metabolic side effects such as hyperlipidaemia and hyperglycaemia. A middle-aged man presented with epigastric and flank pain associated with nausea, and was noted to have elevated triglycerides (3590 mg/dL or 40.53 mmol/L), lipase and glucose. Haematological parameters revealed neutropenia with pancytopaenia. The patient was started on conservative management for acute pancreatitis, and on intravenous insulin and oral gemfibrozil for lowering of his triglycerides. He gradually improved and was transitioned to oral atorvastatin and fenofibrate. His triglycerides, glucose and leucocyte counts normalised at discharge and he was transitioned to ziprasidone. The combination of hypertriglyceridaemia, worsening hyperglycaemia and neutropenia made us suspect quetiapine as the causative agent. Medications cause only 0.1-7% of acute pancreatitis cases, with quetiapine implicated in only five-reported cases. Hypertriglyceridaemia (>600 mg/dL or 6.77 mmol/L) is frequently reported with quetiapine use, but severe hypertriglyceridaemia (>1000 mg/dL or 11.29 mmol/L) has been reported in <10 patients.

Experimental investigation of the effects of the acoustical conditions in a simulated classroom on speech recognition and learning in children.

The potential effects of acoustical environment on speech understanding are especially important as children enter school where students' ability to hear and understand complex verbal information is critical to learning. However, this ability is compromised because of widely varied and unfavorable classroom acoustics. The extent to which unfavorable classroom acoustics affect children's performance on longer learning tasks is largely unknown as most research has focused on testing children using words, syllables, or sentences as stimuli. In the current study, a simulated classroom environment was used to measure comprehension performance of two classroom learning activities: a discussion and lecture. Comprehension performance was measured for groups of elementary-aged students in one of four environments with varied reverberation times and background noise levels. The reverberation time was either 0.6 or 1.5 s, and the signal-to-noise level was either +10 or +7 dB. Performance is compared to adult subjects as well as to sentence-recognition in the same condition. Significant differences were seen in comprehension scores as a function of age and condition; both increasing background noise and reverberation degraded performance in comprehension tasks compared to minimal differences in measures of sentence-recognition.

Avoiding allograft length mismatch during anterior cruciate ligament reconstruction: patient height as an indicator of appropriate graft length.

BACKGROUND: Given the increasing use of allografts in anterior cruciate ligament reconstruction, selection of appropriate-sized grafts may help individual surgeons as well as the efficiency of the overall system for graft distribution. HYPOTHESIS: Recipient patient height can predict the desired length for the tendinous portion of a patellar bone-tendon-bone allograft in anterior cruciate ligament reconstruction. STUDY DESIGN: Cohort study (Prognosis); Level of evidence, 2. METHODS: A series of 414 knees in 392 consecutive patients undergoing magnetic resonance imaging evaluation of knee pain were enrolled in the study. Data collected from magnetic resonance imaging included patella and patellar tendon length and intraarticular length of the anterior cruciate ligament. Patient age, height, weight, and gender were recorded. Linear regression analysis assessed the correlation between patient height and intraarticular length of the anterior cruciate ligament as well as patellar tendon length. The effect of variance in age, weight, and gender on anterior cruciate ligament intraarticular length was also measured. RESULTS: A strong positive correlation was found between intraarticular length of the anterior cruciate ligament and patient height (Pearson r = 0.73; P < .001). Anterior cruciate ligament length (y, in millimeters) as a function of height (x, in inches) can be expressed as y = 1.17x - 41.29. As a function of height (x, in centimeters), anterior cruciate ligament length (y, in millimeters) can be expressed as y = 0.4606x - 41.29. Age, gender, and weight did not significantly influence this relationship. A weak positive association was found between patient height and patellar tendon length. CONCLUSION: Patient height can predict the desired length of the tendinous portion of a patellar bone-tendon-bone allograft. An addition of 10 mm is made to the predicted anterior cruciate ligament length to allow for aperture tibial and femoral fixation. Patellar bone-tendon-bone allografts can be requested based on recipient patient height as follows: 5 ft, 0 in to 5 ft, 6 in: tendinous length/total length, 45 mm/95 mm; 5 ft, 7 in to 6 ft, 1 in: 50 mm/100 mm; > 6 ft, 1 in: 55 mm/105 mm.
