Abstract
Background The American Medical Association and National Institutes of Health recommend online health information be written at a 6th grade or lower reading level for clear understanding. While syntax reading grade level has previously been utilized, those analyses do not determine whether readers are processing key information (understandability) or identifying available actions to take (actionability). The Patient Education Materials Assessment Tool (PEMAT-P) is a method to measure the understandability and actionability of online patient education materials. The purpose of this study was to evaluate online resources regarding rotator cuff repair utilizing measures of readability, understandability, and actionability. Methods The search term "rotator cuff surgery" was used in two independent online searches to obtain the top 50 search results. The readability of included resources was quantified using valid objective algorithms: Flesch-Kincaid Grade-Level, Simple Measure of Gobbledygook grade, Coleman-Liau Index, and Gunning Fog Index. The PEMAT-P form was used to assess actionability and understandability. Results A total of 49 unique websites were identified to meet our inclusion criteria and were included in our analysis. The mean Flesch-Kincaid Grade Level graded materials at a 10.6 (approximately a 10th grade reading level), with only two websites offering materials at a 6th grade reading level or below. The remaining readability studies graded the mean reading level at high school or greater, with the Gunning Fog Index scoring at a collegiate reading level. Mean understandability and actionability scores were 64.6% and 29.5%, respectively, falling below the 70% PEMAT score threshold for both scales. Fourteen (28.6%) websites were above the threshold for understandability, while no website (0%) scored above the 70% threshold for actionability. When comparing source categories, commercial health publishers provided websites that scored higher in understandability (P < .05), while private practice materials scored higher in actionability (P < .05). Resources published by academic institutions or organizations scored lower in both understandability and actionability than private practice and commercial health publishers (P < .05). No readability, understandability, or actionability score was significantly associated with search result rank. Conclusion Overall, online patient education materials related to rotator cuff surgery scored poorly with respect to readability, understandability, and actionability. Only two (4.1%) of the patient education websites scored at the American Medical Association and National Institutes of Health recommended reading level. Fourteen (28.6%) scored above the 70% PEMAT score for understandability; however, no website met the threshold for actionability.

Abstract
Background Dedifferentiated chondrosarcoma (DCS) is a highly malignant variant that portends a poor prognosis. Although factors such as clinico-pathological characteristics, surgical margin, and adjuvant modalities likely play a role in overall survival, debate continues with varying results on the importance of these indicators. The purpose of this study is (1) To delineate the characteristics, local recurrence (LR), and survival of patients with intermediate (IGCS), high (HGCS) and dedifferentiated (DCS) chondrosarcoma of the extremity by utilizing detailed cases at one tertiary institution. (2) To assess survival between high grade chondrosarcoma and DCS utilizing a less detailed but large cohort from the Surveillance, Epidemiology, and End Results (SEER) database. Methods Twenty-six cases of high-grade (conventional FNCLCC grades 2 and 3, dedifferentiated) chondrosarcoma were identified from an ongoing prospective cohort of 630 sarcoma patients managed surgically at a tertiary referral university hospital between 9/1/2010-12/30/2019. A retrospective review of demographics, tumor characteristics, surgical procedure, treatment course, and survival data was performed to determine prognostic factors for survival. An additional 516 cases of chondrosarcoma were identified from the SEER database. Using the Kaplan-Meier method, both the large database and case series were evaluated, and estimated cause-specific survival was calculated at 1, 2, and 5 years. Results There were 12 IGCS, 5 HGCS, and 9 DCS patients in the single institution cohort. DCS had a higher stage at diagnosis (p=0.04). Limb salvage was the most common procedure performed in every group (11/12 IGCS, 5/5 HGCS, and 7/9 DCS; p=0.56). Margins included 8/12 wide and 3/12 intralesional for IGCS. For HGCS, there were 3/5 wide, 1/5 marginal, and 1/5 intralesional. A majority of DCS margins were wide (8/9) with only 1 marginal. There was no difference of associated margins between the groups (p=0.85), however there was a difference when margins were classified based on numerical measurement (IGCS: 0.125cm (0.1-0.35); HGCS: 0cm (0-0.1); DCS: 0.2cm (0.1-0.5); p=0.03). The overall median follow-up was 26 months (IQR:16.1-70.8). The time interval from resection to death was lower in DCS (11.5 months (10.7-12.2)), followed by IGCS (30.3 months (16.2-78.2)), and HGCS (55.1 months (32.0-78.2; p=0.047). LR occurred in 5/9 DCS, 1/5 HGCS, and 1/14 IGCS patients. Of the DCS patients only 2/6 who received systemic therapy had LR, while all 3/3 who did not receive systemic therapy had LR. Overall systemic therapy and radiation did not impact incidence of LR (p=0.67; p=0.34). However, patients who had LR were 17.5 times more likely to die within one year (HR=17.5, 95%CI (1.01-303.7), p=0.049), after adjusting for the age at the surgery. There was no correlation with the utilization of systemic therapy, radiation therapy, or margin and overall survival (p=0.63, p=0.52, p=0.74). In the SEER patient cohort, 149 cases (28.9%) were DCS and 367 (71.1%) were HGCS. At final follow-up, 49.6% (n=256) of the cohort had a cause of death due to chondrosarcoma. HGCS was associated with higher chance of 1-year survial (p<0.001), 2-year survival (p<0.001), 5-year survival (p<0.001), and overall survival (p<0.001). Additionally, decreased survival was associated with metastatic disease at presentation (p=0.01). Overall limb salvage was most utilized for both HGCS (76.5%) and DCS (74.3%). In regard to limb salvage vs. amputation, there was no difference in survival at 1 year (p=0.10) or 2 year (p=0.13) between the groups, however those who underwent limb salvage procedure had a significantly better chance of survival at 5 years when compared to amputation (HR=1.49 (1.11-1.99); p=0.002). Conclusion High-grade chondrosarcoma remains a fatal disease in many patients, particularly if associated with dedifferentiated subtype. Interestingly, all (100%) DCS patients who did not receive systemic therapy had LR. However, chemotherapy and radiation did not significantly increase survival. In this case series and large database study, HGCS had the smallest surgical margin, but with the longest time interval for both LR and death. Additionally, using the SEER database, DCS and amputation had worse prognosis at the 5-year survival time. Further studies on valuable prognostic influences as well as earlier identification of this rare disease may help in developing better management options. Level of Evidence: III.

Abstract
OBJECTIVES Spin is a reporting bias that presents the beneficial effect of an experimental treatment as greater than what is found in the results of the study. This bias can result in patient care recommendations that are more subjective than objective. The purpose of this study is to identify the prevalence of spin in meta-analysis and systematic review abstracts regarding treatment of midshaft clavicle fractures. METHODS Electronic libraries (MEDLINE, Embase, Web of Science, Google Scholar) were systematically searched. Meta-analyses and systematic reviews regarding treatment of midshaft clavicular fractures were analyzed. The nine most severe types of spin commonly found in abstracts were used as an evaluation tool to assess the articles. Other variables analyzed include year of publication, journal impact factor, number of citations, and methodologic quality according to A Measurement Tool to Assess Systematic Reviews (AMSTAR-2). RESULTS The database search resulted in 401 articles, of which 53 met inclusion criteria. After review, it was found that 52.8% (28/53) of the included articles contained spin within the abstract. Of the nine most severe types of spin found in abstracts, type 3 spin ("selective reporting of or overemphasis on efficacy outcomes or analysis favoring the beneficial effect of the experimental intervention") was found to be the most prevalent 28.3% (15/53). CONCLUSION This study demonstrated the presence of spin in the majority of meta-analyses and systematic review abstracts pertaining to midshaft clavicular fractures. Orthopedic surgeons should be aware and recognize spin as they review articles when deciding the treatment course for such injuries. LEVEL OF EVIDENCE Level 3.

Abstract
Background: Patients undergoing elective procedures often utilize online educational
materials to familiarize themselves with the surgical procedure and expected
postoperative recovery. While the Internet is easily accessible and
ubiquitous today, the ability of patients to read, understand, and act on
these materials is unknown. Purpose: To evaluate online resources about anterior cruciate ligament (ACL) surgery
utilizing measures of readability, understandability, and actionability. Study Design: Cross-sectional study; Level of evidence, 4. Methods: Using the term “ACL surgery,” 2 independent searches were performed utilizing
a public search engine (Google.com). Patient education
materials were identified from the top 50 results. Audiovisual materials,
news articles, materials intended for advertising or medical professionals,
and materials unrelated to ACL surgery were excluded. Readability was
quantified using the Flesch Reading Ease, Flesch-Kincaid Grade Level, Simple
Measure of Gobbledygook, Coleman-Liau Index, Automated Readability Index,
and Gunning Fog Index. The Patient Education Materials Assessment Tool for
Printable Materials (PEMAT-P) was utilized to assess the actionability and
understandability of materials. For each online source, the relationship
between its Google search rank (from first to last) and its readability,
understandability, and actionability was calculated utilizing the Spearman
rank correlation coefficient (ρS). Results: Overall, we identified 68 unique websites, of which 39 met inclusion
criteria. The mean Flesch-Kincaid Grade Level was 10.08 ± 2.34, with no
website scoring at or below the 6th-grade level. Mean understandability and
actionability scores were 59.18 ± 10.86 (range, 33.64-79.17) and 34.41 ±
22.31 (range, 0.00-81.67), respectively. Only 5 (12.82%) and 1 (2.56%)
resource scored above the 70% adequate PEMAT-P threshold mark for
understandability and actionability, respectively. Readability (lowest
P value = .103), understandability (ρS =
–0.13; P = .441), and actionability (ρS = 0.28;
P = .096) scores were not associated with Google
rank. Conclusion: Patient education materials on ACL surgery scored poorly with respect to
readability, understandability, and actionability. No online resource scored
at the recommended reading level of the American Medical Association or
National Institutes of Health. Only 5 resources scored above the proven
threshold for understandability, and only 1 resource scored above it for
actionability.

Abstract
BACKGROUND As overall cancer survival continues to improve, the incidence of metastatic lesions to the bone continues to increase. The subsequent skeletal related events that can occur with osseous metastasis can be debilitating. Complete and impending pathologic femur fractures are common with patients often requiring operative fixation. However, the efficacy of an intramedullary nail construct, on providing stability, continue to be debated. Therefore, the purpose of this study was to utilize a synthetic femur model to determine 1) how proximal femur defect size and cortical breach impact femur load to failure (strength) and stiffness, and 2) and how the utilization of an IMN, in a prophylactic fashion, subsequently alters the overall strength and stiffness of the proximal femur. METHODS A total of 21 synthetic femur models were divided into four groups: 1) intact (no defect), 2) 2 cm defect, 3) 2.5 cm defect, and 4) 4 cm defect. An IMN was inserted in half of the femur specimens that had a defect present. This procedure was performed using standard antegrade technique. Specimens were mechanically tested in offset torsion. Force-displacement curves were utilized to determine each constructs load to failure and overall torsional stiffness. The ultimate load to failure and construct stiffness of the synthetic femurs with defects were compared to the intact synthetic femur, while the femurs with the placement of the IMN were directly compared to the synthetic femurs with matching defect size. RESULTS The size of the defect invertedly correlated with the load the failure and overall stiffness. There was no difference in load to failure or overall stiffness when comparing intact models with no defect and the 2 cm defect group (p=0.98, p=0.43). The 2.5 cm, and 4.5 cm defect groups demonstrated significant difference in both load to failure and overall stiffness when compared to intact models with results demonstrating 1313 N (95% CI: 874-1752 N; p<0.001) and 104 N/mm (95% CI: 98-110 N/mm; p=0.03) in the 2.5 cm defect models, and 512 N (95% CI: 390-634 N, p<0.001) and 21 N/mm (95% CI: 9-33 N/mm, p<0.001) in the models with a 4 cm defect. Compared to the groups with defects, the placement an IMN increased overall stiffness in the 2.5 cm defect group (125 N/mm; 95% CI:114-136 N/mm; p=0.003), but not load to failure (p=0.91). In the 4 cm defect group, there was a significant increase in load to failure (1067 N; 95% CI: 835-1300 N; p=0.002) and overall stiffness (57 N/mm; 95% CI:46-69 N/mm; p=0.001). CONCLUSION Prophylactic IMN fixation significantly improved failure load and overall stiffness in the group with the largest cortical defects, but still demonstrated a failure loads less than 50% of the intact model. This investigation suggests that a cortical breach causes a loss of strength that is not completely restored by intramedullary fixation. Level of Evidence: II.

Abstract
Background The direct anterior approach (DAA) for total hip arthroplasty (THA) has been popularized as a less invasive technique, however outcomes within the first year of practice after fellowship have not been investigated. The primary aim was to determine differences in complications and outcomes between DAA and posterior approach (PA) in the first year of practice. The secondary aim was to determine if there was a learning curve factor in DAA and PA after fellowship training. Methods THA cases performed by two surgeons during their first year of practice were reviewed. Overall, 181 THAs (91 DAA, 90 PA) in 168 patients, were performed. Intraoperative differences (blood loss, operative time), hospital stay, complications, reoperations, and revisions were compared. Results Overall surgical complications were similar between DAA and PA (11% vs. 9%, p=0.64), but complication profiles were different: dislocation (1% vs. 4%, p=0.17), intraoperative femoral fracture (2% vs. 1%, p=0.32), postoperative periprosthetic fractures (2% vs. 3%, p=0.64). neuropraxia (3% vs. 0%, p=0.08). There was no difference in rate of reoperation (1% vs. 3%, p=0.31). There was a difference in rate of revision at final follow-up (0% vs. 6%, p=0.02). DAA consisted of longer operative time (111 vs. 99 minutes; p<0.001), however was only significant in the first 50 cases (p<0.001), while the subsequent cases were similar (p=0.31). There was no difference in the first 50 cases compared to the subsequent cases for either approach regarding blood loss, complications, reoperations, or revisions. Conclusion DAA and PA for THA performed within the first year of practice exhibit similarly low complication rates, but complication profiles are different. In our series, PA did demonstrate a higher risk of revision at final follow-up. A learning curve is not unique to the DAA. Both DAA and PA THA exhibited a learning curve in the first 50 cases performed at the start of a surgeon's practice. Level of Evidence: III.

Abstract
BACKGROUND While muscle atrophy is a function of normal aging, loss of muscle in the setting of hip and knee osteoarthritis (OA) has been observed using radiographic studies. There is limited data available regarding changes in extremity composition using bioimpedance (BIA). The purpose of this study was to assess the changes in extremity composition in patients with isolated, unilateral hip or knee OA using BIA. METHODS Patients presenting to our institution's adult reconstruction clinic from February 2020 to April 2021 were retrospectively reviewed to identify those with isolated, unilateral hip and knee OA. The InBody 770 Body Composition Analyzer (InBody USA, Cerritos, California) was used to perform a complete body composition assessment, per protocol. Lean extremity mass (LEM), fat mass (FM), intracellular water (ICW), extremity body water (EBW = ICW + extracellular water (ECW)) and phase angle (PA) were determined. Differences between the affected (OA) and unaffected (no OA) extremities were compared using t-tests. RESULTS 38 patients had isolated hip OA. The mean age was 60.8 (±11.7) years, mean BMI was 31.7 (±6.8) kg/m2, and 39.5% were female. LEM, FM, EBW, ICW, and PA were significantly decreased in the hip OA extremity (LEM: 20.0 vs. 20.4 kg, p=0.0008, FM: 8.8 vs. 8.9 kg, p=0.0049, EBW: 15.7 vs 16.0, p=0.0011, ICW: 9.5 vs. 9.7 L, p=0.0004, PA: 4.5 vs 4.9º, p<0.0001). There were 25 patients with isolated knee OA. Mean age was 62.8 (±11.3) years, mean BMI was 33.6 (±6.9) kg/m2, and 52.0% were female. FM and PA were significantly lower in the knee OA extremity (11.3 vs 11.4 kg, p=0.0291, 4.5 vs 4.9º, p<0.0001). There were no significant differences in LEM, EBW, and ICW between the knee OA extremity and the unaffected extremity. CONCLUSION Patients with isolated, unilateral hip OA had decreased LEM, FM, EBW, and ICW in the affected extremity. Both unilateral hip and knee OA was associated with decreased PA, suggestive of greater underlying dysfunction in muscle or cellular performance. Further study is needed to better define when these abnormalities develop, how they progress over time, and the impact of targeted interventions in reversing these changes. Level of Evidence: III.

Abstract
BACKGROUND Residency is known to consist of rigorous training that has contributed to increased rates of resident burn out, depression, and suicide. There have been recent efforts to attempt to combat and solve the rising levels of mental health concerns amongst physicians and physicians in training. While studies have examined the adverse effects of medical training on mental health, few have examined the associated changes in physical health. This study aimed to identify and compare baseline body composition and hand grip strength of orthopaedic surgery residents. The second aim was to identify and compare changes that may occur over the course of the training program. METHODS First year orthopaedic surgery residents ("interns") were recruited to undergo body composition measurements via bioimpedance analysis (BIA) during their first, third, and twelfth month of post-graduate training. At each interval, three hand-grip-strength measurements per hand were captured. Additionally, orthopaedic surgery residents who had already completed their first year ("non-interns") were recruited to undergo baseline and 12-month BIA for comparison. RESULTS Six interns and six non-interns were recruited. The interns lost 2.88 ± 4.26 kg (-3.31% ± 4.75%) of their initial body mass with most of the loss being body fat mass (1.97 ± 2.62 kg) by three months. Interns recovered a fair amount of mass loss by 12 months with a net change of -0.78 ± 3.14 kg (-1.09% ± 3.90%). Non-interns experienced an overall net weight gain (1.20 ± 3.64 kg; 1.68% ± 5.55%) over the same period. Intern HGS changed by -1.92 ± 2.49 kg and 3.39 ± 2.34 kg at 3- (n=6) and 12-months (n=3), respectively. CONCLUSION This study demonstrates that there is an appreciable decrease in overall body mass, lean tissue mass, and body fat throughout the orthopaedic resident's intern year. The results demonstrate an initial fall in each body metric and strength by 3-months followed by partial recovery by 12-months. This pattern contrasts the average gain of body mass in each measured metric by non-interns. This study is limited by population sizes and by incompleteness of HGS data. Level of Evidence: II.

Abstract
Background The outcomes of pilon fractures are multifactorial. Anterior articular impaction requires sagittal plane correction (anterior distal tibia angle (ADTA)) with articular reduction. However, there is a risk of avascular necrosis of the articular fragments and postoperative tibiotalar arthritis. The purpose of this study was to determine if the presence of anterior impaction affects radiographic alignment after definitive fixation. Methods Retrospective cohort study of patients who underwent operative management for pilon fractures at two academic, level 1 trauma centers between September 2005-September 2016. Fractures were categorized as having anterior impaction or no anterior impaction after review of preoperative radiographic and computer tomography imaging. Patient demographics and postoperative time to union was recorded. Quality of reduction was measured using (ADTA) (degrees), lateral distal tibia angle (LDTA) (degrees), and lateral talar station (LTS) (millimeters) from postoperative radiographs. Statistical analysis compared fracture patterns with anterior impaction to those without. Results 208 patients met inclusion criteria. 132 fractures (63.4%) were determined to have anterior impaction. Cohorts were similar in demographics and medical comorbidities (p>0.05). Mean ADTA, LTDA, and LTS for the anterior impaction group 83.5°, 89.7°, and 2.4mm versus 84.6°, 89.9°, and 2.0mm in the group without anterior impaction. Cohorts significantly differed in ADTA(p=0.01), but not LDTA(p=0.12) or LTS(p=0.44). No significant differences were found between cohorts with infection (>0.05), nonunion(p=0.76), unplanned reoperation(p=0.56), or amputation(p=0.34). Conclusion This study demonstrated no significant differences in the coronal or sagittal plane alignment when comparing definitively fixed pilon fractures with and without anterior impaction. Additional studies are needed to evaluate the longterm clinical impact of failing to restore ADTA. Level of Evidence: III.

Abstract
Background Academic teaching institutions perform approximately one third of all orthopedic procedures in the United States. Revision total knee arthroplasty (rTKA) is a complex and challenging procedure that requires expertise and extensive planning, however the impact of resident involvement on outcomes is poorly understood. The aim of the study was to investigate whether resident involvement in rTKA impacts postoperative complication rates, operative time, and length of hospital stay (LOS). Methods The American College of Surgeons National Surgical Quality Improvement Program registry was queried to identify patients who underwent rTKA procedures from 2006-2012 using CPT codes 27486 and 27487. Cases were classified as resident involved or attending only. Demographics, comorbidities, and 30-day postoperative complications were analyzed. Multiple logistic regression analysis was performed to identify independent risk factors for increased 30-day postoperative complications. Wilcoxon rank sum tests were performed to determine the impact of resident involvement on operative time and LOS with significance defined as p<0.05. Results In total, 2,396 cases of rTKA were identified, of which 972 (40.6%) involved residents. The two study groups were similar, however the resident involved cohort had more patients with hypertension and ASA class 3 (p=0.02, p=0.04). There was no difference in complications between the cohorts (No Resident vs Resident-involved: 7.0% vs 6.7%, p=0.80). Multivariate analysis identified obesity (OR: 1.81, 95% CI: 1.18-2.79, p=0.01), morbid obesity (OR: 1.66, 95% CI: 1.09-2.57, p=0.02), congestive heart failure (OR: 5.97, 95% CI: 1.19-24.7, p=0.02), and chronic prosthetic joint infection (OR: 3.16, 95% CI: 2.184.56, p<0.01), as independent risk factors for 30-day complications after rTKA. However, resident involvement was not associated with complications within 30-days following rTKA (OR: 0.91, 95% CI: 0.65-1.26, p=0.57). Resident involvement was associated with increased operative time (p<0.001) and LOS (P<0.001). Conclusion Resident involvement in rTKA cases is not associated with an increased risk of 30-day postoperative complications. However, resident operative involvement was associated with longer operative time and length of hospital stay. Level of Evidence: III.

Abstract
BACKGROUND Obesity poses a challenge to thromboembolic prophylaxis following total joint arthroplasty (TJA). The purpose of this study is to evaluate a weight-based aspirin dosing regimen for prevention of venous thromboembolism (VTE) following TJA. METHODS This is a retrospective observational study of 2403 patients who underwent primary total hip or knee arthroplasty at one institution. A weight-based aspirin dosing regimen for VTE prophylaxis was administered to 1247 patients: patients weighing ≥120 kg received 325 mg aspirin twice daily (BID) and those weighing <120 kg received 81 mg aspirin BID for 4 weeks. In total, 1156 patients in the comparison cohort received 81 mg aspirin BID. VTE and gastrointestinal bleeding events were identified through chart review at 42 days and 6 months postoperatively. A multivariable logistic regression was performed to adjust for covariates. RESULTS The weight-based aspirin cohort had a significantly lesser incidence of VTE at 42 days (P = .03, relative risk [RR] 0.31, 95% confidence interval 0.12-0.82) and 6 months (P = .03, RR 0.38, 95% confidence interval 0.18-0.80). There was no difference in VTE incidence between total hip arthroplasty and total knee arthroplasty cases (P = .8). There was no difference in gastrointestinal bleeding events between the cohorts at 42 days (P = .69) or 6 months (P = .92). Subanalysis of patients weighing ≥120 kg demonstrated a significant difference between the cohorts with a VTE incidence of 3.48% and 0% in the 81 mg and weight-based cohorts, respectively (P = .02). CONCLUSION Patients prescribed a weight-based aspirin regimen had significantly fewer VTEs after TJA compared to historical controls with an RR reduction of 69% at 6 weeks and 62% at 6 months postoperatively. This suggests the need to factor patient weight when determining postoperative VTE prophylaxis with aspirin.

Abstract
BACKGROUND The prediction of survival is valuable to optimize treatment of metastatic long-bone disease. The Skeletal Oncology Research Group (SORG) machine-learning (ML) algorithm has been previously developed and internally validated. The purpose of this study was to determine if the SORG ML algorithm accurately predicts 90-day and 1-year survival in an external metastatic long-bone disease patient cohort. METHODS A retrospective review of 264 patients who underwent surgery for long-bone metastases between 2003 and 2019 was performed. Variables used in the stochastic gradient boosting SORG algorithm were age, sex, primary tumor type, visceral/brain metastases, systemic therapy, and 10 preoperative laboratory values. Model performance was calculated by discrimination, calibration, and overall performance. RESULTS The SORG ML algorithms retained good discriminative ability (area under the cure [AUC]: 0.83; 95% confidence interval [CI]: 0.76-0.88 for 90-day mortality and AUC: 0.84; 95% CI: 0.79-0.88 for 1-year mortality), calibration, overall performance, and decision curve analysis. CONCLUSION The previously developed ML algorithms demonstrated good performance in the current study, thereby providing external validation. The models were incorporated into an accessible application (https://sorg-apps.shinyapps.io/extremitymetssurvival/) that may be freely utilized by clinicians in helping predict survival for individual patients and assist in informative decision-making discussion before operative management of long bone metastatic lesions.

Abstract
The purpose of this study was to establish preoperative validity of the Patient-Reported Outcomes Measurement Information System physical function computer adaptive test (PROMIS PF-CT) with legacy patient-reported outcome measures (PROMs) for meniscal root tears (MRTs). Our study included 51 patients (52 knees) with MRT. Patients completed PROMIS PF-CT, Short Form 36 (SF-36 physical function, pain, general health, vitality, social function, emotional well-being, role limitations due to physical health, and role limitations due to emotional problems), Knee Injury and Osteoarthritis Outcome Score (KOOS pain, symptoms, activities of daily living [ADLs], sports, and quality of life [QOL]), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC pain, stiffness, and function), EuroQol-5 dimensions (EQ-5D), and Knee Activity Scale questionnaires at their preoperative visit. Correlations between the PROMs listed above were evaluated along with floor and ceiling effects. Correlations were defined as weak (0.2-0.39), moderate (0.4-0.59), strong (0.6-0.79), and very strong (0.8-1.0). Preoperative data showed that PROMIS PF-CT has a strong correlation with SF-36 PF, KOOS-ADL, WOMAC-function, and EQ-5D; and moderate correlation with KOOS-sport, KOOS-pain, KOOS-symptoms, KOOS-QOL, WOMAC-pain, and WOMAC-stiffness. The Knee Activity Scale did not show any significant correlation with PROMIS PF-CT (r = 0.12, p = 0.2080). Of all the PROMs administered, PROMIS PF-CT demonstrated no floor or ceiling effects compared with 11.54% ceiling effect in KOOS-sports, and 5.77% floor effect in KOOS-ADL. On average, patients answered fewer PROMIS PF-CT questions (4.15 ± 0.72). PROMIS PF-CT is a valuable tool to assess preoperative patient-reported physical function in patients that may undergo MRT repair. It correlates strongly with other well-established PROMs. It also demonstrated no floor or ceiling effects and demonstrated a low test burden in our sample of 52 knees. This is a level III, prognostic retrospective comparative study.

Abstract
BACKGROUND Periacetabular osteotomy (PAO) is a well-established procedure to improve function and reduce pain in the non-arthritic dysplastic hip. PAO and hip arthroscopy are often performed together; however, there is concern that hip arthroscopy increases difficulty of PAO due to arthroscopic fluid extravasation. The purpose of the current study was to examine the effect of performing hip arthroscopy prior to PAO under the same anesthetic on PAO operative time and postoperative complications. METHODS A retrospective review of all PAO cases during a two-year period at a single academic institution was performed. Cases were stratified into two groups based on whether concomitant hip arthroscopy was performed. In the combined hip arthroscopy and PAO group, hip arthroscopy was performed prior to PAO under the same general anesthetic in all cases. Student t-test was utilized to compare the operative times between the two study groups and Chi Square was used to compare categorical variables. RESULTS During the two-year study period, 93 total PAO cases in 86 patients (mean age: 23.5 + 8.7 years; 81.4% female) were performed. Of these, 67 PAO surgeries (72.0%) were performed following hip arthroscopy. The total complication rate was 2.2% with one postoperative complication occurring in each group. There was no difference in mean PAO operative time between the two study groups (PAO: 127.6 + 18.0 minutes; PAO with hip arthroscopy: 125.4 + 16.8 minutes; p=0.570). CONCLUSION Performing hip arthroscopy prior to PAO under the same general anesthetic does not significantly increase PAO operative time or postoperative complications.Level of Evidence: IV.

Abstract
BACKGROUND Parents often access online resources to educate themselves when a child is diagnosed with clubfoot and/ or prior to treatment initiation. In order to be fully understood by the average adult American, online health information must be written at an elementary school reading level. It was hypothesized that current available online resources regarding clubfoot would score poorly on objective measures of readability (syntax reading grade-level), understandability (ability to process key messages), and actionability (providing actions the reader may take). Additionally, it was hypothesized that the outcomes measured would not correlate with the order of listed search results. METHODS Patient education materials were identified utilizing two independent online searches (Google.com) of the term "Clubfoot". From the top 50 search results, websites were included if directed at educating patients and their families regarding clubfoot. News articles, non-text material (video), research and journal articles, industry websites, and articles not related to clubfoot were excluded. The readability of included resources was quantified using the Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG) Grade, Coleman-Liau Index (CLI), Gunning-Fog Index( GFI) and Automated Reading Index (ARI). The Patient Education Materials Assessment Tool (PEMAT) was used to assess actionability and understandability using a 0-100% scale for both measures of interest. RESULTS Of the 55 unique websites, 37 websites (65.2%) met inclusion criteria. The mean FKGL was 9.2 (+/- 2.1) with only three websites (7.32%) having a reading level ≤6. Mean understandability and actionability scores were 67.2±12.6 and 25.4±25.2, respectively. Thirteen (35%) websites met the understandability threshold of ≥70% but no websites met the actionability criteria. No readability statistics were statistically associated with Google™ search rank (p=0.07). There was no association between readability (p=0.94) nor actionability (p=0.18) scores and Google™ rank. However, understandability scores did correlate with Google™ rank (p=0.02). CONCLUSION Overall, online clubfoot educational materials scored poorly with respect to readability, understandability, and actionability. There is an association with Google™ search rank for understandability of clubfoot materials. However, readability and actionability are not significantly associated with search rank. In the era of shared decision-making, efforts should be made by medical professionals to improve the readability, understandability, and actionability of online resources in order to optimize parent understanding and facilitate effective outcomes.Level of Evidence.

Abstract
PURPOSE To compare 90-day postoperative complications between patients undergoing outpatient versus inpatient arthroscopic rotator cuff repairs (RCR) and identify risk factors associated with postoperative complications. METHODS An administrative claims database was used to identify patients undergoing arthroscopic RCR from 2007 to 2015. Patients were categorized based on length of hospital stay (LOS) with inpatient RCR defined as patients with ≥1 day LOS, and outpatient RCR as patients discharged day of surgery (LOS = 0). Inpatient and outpatient RCR groups were matched based on age, sex, Charlson comorbidity index (CCI), and various medical comorbidities using 1:1 propensity score analysis. Patient factors, concomitant procedures, total adverse events (TAEs), medical adverse events (MAEs), and surgical adverse events (SAEs) were compared between the matched groups. Multiple logistic regression analysis was performed to identify risk factors associated with increased complications. RESULTS After matching, there were 2812 patients (50% outpatient) included in the study. Within 90 days following arthroscopic RCR, the incidence of TAEs (8.9% vs 3.6%, P < .0001), SAEs (2.7% vs 0.9%, P = .0002), and MAEs (6.4% vs 3.0%, P < .0001) were significantly greater for the inpatient RCR group. The multivariate model identified inpatient RCR (LOS ≥1 day), greater CCI, and anxiety or depression as independent predictors for TAEs after arthroscopic RCR. Open biceps tenodesis and inpatient RCR were independent predictors of SAEs, whereas greater CCI, anxiety or depression, and inpatient RCR were independent predictors for MAEs within 90 days after arthroscopic RCR. CONCLUSIONS Inpatient arthroscopic RCR is associated with increased risk of 90-day postoperative complications compared with outpatient. However, there is no difference for all-cause or pain-related emergency department visits within 90 days after surgery. In addition, the multivariate model identified inpatient RCR, greater CCI, and diagnosis of anxiety or depression as independent risk factors for 90-day TAEs after arthroscopic RCR.

Abstract
Purpose To determine trends in arthroscopic-assisted tibial plateau fracture fixation (AATPFF), to evaluate trends in the overall rate of tibial plateau fracture fixation, and to compare postoperative complications between AATPFF and traditional tibial plateau fixation. Methods A retrospective review of patients undergoing AATPFF and traditional tibial plateau fixation was conducted using the Humana Inc. administrative database from 2007 to 2016. A 1:1 propensity match was utilized to match patients in the 2 study groups based on age, sex, obesity, diabetes, hypertension, chronic obstructive pulmonary disease, depression or anxiety, and smoking history. Postoperative complications were grouped as minor medical complications, major medical complications, surgical complications, emergency department visits, and reoperation. Linear regression analysis was used to assess trends and Pearson's χ2 test was used to compare postoperative complications with statistical significance defined as P < .05. Results In total, 522 patients underwent AATPFF and 3920 patients underwent traditional tibial plateau fracture fixation. There was a 4-fold increase in the use of AATPFF over the study period (P = .0173). Similarly, there was an increase in the utilization of traditional tibial plateau fracture fixation, although to a lesser extent (1.33-fold). After propensity matching, the traditional fixation group demonstrated significantly higher rates of minor medical complications (8.2% vs 2.7%, P = .0002), major medical complications (9.9% vs 4.6%, P = .0018), surgical complications (13.2% vs 2.7%, P < .0001), and emergency department visits (21.4% vs 13.5%, P < .0001) within 90 days of surgery compared with the AATPFF group. There was no difference in reoperation rates within 90 days between the 2 groups (2.9% vs 3.6%, P = .85). Conclusions The incidence of tibial plateau fracture fixation is increasing, however, use of AATPFF is increasing at a faster rate compared to traditional techniques. Furthermore, the addition of knee arthroscopy to fracture fixation does not increase the risk of complication, reoperation, or emergency department visit within 90 days. Level of Evidence III, retrospective matched cohort.

Abstract
PURPOSE To (1) report the frequency of postoperative opioid prescriptions after elbow arthroscopy, (2) evaluate whether filling opioid prescriptions preoperatively placed patients at increased risk of requiring more opioid prescriptions after surgery, and (3) determine patient factors associated with postoperative opioid prescription needs. METHODS A national claims-based database was queried for patients undergoing primary elbow arthroscopy. Patients with prior total elbow arthroplasty or septic arthritis of the elbow were excluded. Patients who filled at least 1 opioid prescription between 1 and 4 months prior to surgery were defined as the preoperative opioid-use group. Monthly relative risk ratios for filling an opioid prescription were calculated for the first year after surgery. Multiple logistic regression analysis was performed to identify factors associated with opioid use at 3, 6, 9, and 12 months after elbow arthroscopy, with P < .05 defined as significant. RESULTS We identified 1,138 patients who underwent primary elbow arthroscopy. The preoperative opioid-use group consisted of 245 patients (21.5%), 61 of whom (24.9%) were still filling opioid prescriptions 12 months after surgery. The multivariate analysis determined that the preoperative opioid-use group was at increased risk of postoperative opioid prescription filling at 3 months (odds ratio [OR], 9.02; 95% confidence interval [CI], 5.98-13.76), 6 months (OR, 8.74; 95% CI, 5.57-13.92), 9 months (OR, 7.17; 95% CI, 4.57-11.39), and 12 months (OR, 6.27; 95% CI, 3.94-10.07) after elbow arthroscopy. Patients younger than 40 years exhibited a decreased risk of postoperative opioid prescription filling at 3 months (OR, 0.49; 95% CI, 0.25-0.91), 6 months (OR, 0.19; 95% CI, 0.06-0.50), 9 months (OR, 0.48; 95% CI, 0.22-0.97), and 12 months (OR, 0.44; 95% CI, 0.19-0.94) after surgery. CONCLUSIONS Preoperative opioid filling, fibromyalgia, and psychiatric illness are associated with an increased risk of prolonged postoperative opioid after elbow arthroscopy. Patient age younger than 40 years and chronic obstructive pulmonary disease are associated with a decreased risk of postoperative opioid prescription filling within the first postoperative year. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
PURPOSE Sagittal plane alignment beyond articular reduction and its effect on clinical outcomes has not been emphasized. Surgical approach may influence a surgeon's ability to correct the sagittal plane alignment. The purpose of our study was to evaluate how surgical approach impacts anterior distal tibial angle (ADTA) and lateral talar station (LTS). Our hypothesis was that the anterolateral (AL) approach would improve the sagittal plane parameters due to the primary plate placement. PATIENTS AND METHODS A retrospective review was performed on patients who underwent operative management for pilon fractures at 2 ACS Level 1 Academic Trauma Centers. Clinical data points including demographics, comorbidities, AO/OTA classification, surgical approach, and complications were recorded. Quality of reduction was measured using the ADTA, lateral distal tibia angle (LDTA), and lateral talar station (LTS) from radiographs. RESULTS 580 pilon fractures met inclusion criteria. When compared to the AL approach, the modified anteromedial (AM) approach had decreased rates of local wound care, and unplanned reoperations. The AM approach had increased rates of superficial infection, deep infection, non-union, and amputations. There was no difference in ADTA, LDTA, or LTS between the AM and AL approach (P = 0.49, P = 0.41, P = 0.85). There was a difference in LTS with tobacco users (P = 0.02). CONCLUSIONS The sagittal plane alignment does not appear to be affected by the surgical approach. Therefore, the surgical approach to pilon fractures should be based on the fracture pattern and the patient's soft tissue envelope. This study shows that the AM is a relatively safe and effective approach to complex fractures and the surgeon should consider the specific fracture pattern and patient soft tissue envelope when choosing the specific approach.

Abstract
The objective of this study is to compare the cyclic loading strength and ultimate failure load in suture anchor repair versus transosseous tunnel repair of patellar tendons using a cadaver model. Twelve cadaveric patella specimens were used (six matched pairs). Dual-energy X-ray absorptiometry (DXA) measurements were performed to ensure equal bone quality among groups. All right knees were assigned to the suture anchor repair group (n = 6), whereas all left knees were assigned to the transosseous bone tunnel group (n = 6). Suture type and repair configuration were equivalent. After the respective procedures were performed, each patella was mounted into a gripping jig. Tensile load was applied at a rate of 1 Hz between magnitudes of 50 and 150 N, 50 and 200 N, 50 and 250 N, and tensile load at a rate of 0.1 mm/s until failure. Failure was defined as a sharp deviation in the linear load versus displacement curve, and failure mode was recorded. DXA measurements demonstrated equivalence of bone quality between the two groups (p > 0.05). During cyclic load testing, there was only a statistically significant difference between the groups with regard to cyclic loading at the 50 to 200 N loading cycle (p = 0.010). There was no statistically significant difference between the groups with regard to ultimate load to failure (p = 0.43). Failure mode within the suture anchor cohort occurred through anchor pullout except for one, which failed through the tendon. All specimens within the transosseous cohort failed through the midsubstance of the tendon except for one, which failed through suture breakage. Suture anchor repair demonstrated a similar biomechanical profile regarding cyclic loading and ultimate load to failure when compared with "gold standard" transosseous tunnel patellar tendon repair with a trend toward less gapping in the suture anchor group. Using suture anchors for repair of the patella tendon has similar biomechanical properties to transpatellar tunnels but may provide other clinical advantages.

Abstract
BACKGROUND MRI in the evaluation of end-stage knee joint osteoarthritis (OA) is usually unnecessary when radiographic and clinical evidence of gonarthrosis is clear. The purpose of this study was to assess the prevalence of MRI scans ordered in patients with radiographically obvious gonarthrosis and to examine the characteristics of health care providers who ordered these imaging studies. METHODS We retrospectively identified 164 patients diagnosed with moderate to severe OA who were referred for total knee replacement (TKA) over a one-year period. The percentage of patients who had an MRI scan with or without X-ray, within the preceding 3 months prior to referral, were calculated. Subgroups were analyzed to identify characteristics that may influence the decision to order an MRI, including K-L grade, provider type, level of training, and practice location. RESULTS Of 145 patients, 19 (13.1%) presented with an MRI scan. Between the number of MRI scans ordered, there was a significant difference when comparing physicians versus non-physicians, with physicians ordering less MRI scans (p=0.018). There was a significant difference when comparing non-academic versus academic, with academic providers ordering less MRI scans (p=0.044). There was no significant difference with fellowship training or provider proximity to our academic institution. CONCLUSIONS In this study, 13.1% of patients with radiographically obvious knee OA obtained an MRI prior to referral for TKA. Non-physicians and non-academic physicians were more likely to order MRI scans. Improved education for referring providers may be necessary to decrease overuse of MRI in the diagnosis of moderate to severe arthritis. LEVEL OF EVIDENCE Level II.

Abstract
BACKGROUND Noncontact anterior cruciate ligament (ACL) injury in adolescent female athletes is an increasing problem. The knee-ankle separation ratio (KASR), calculated at initial contact (IC) and peak flexion (PF) during the drop vertical jump (DVJ), is a measure of dynamic knee valgus. The Microsoft Kinect V2 has shown promise as a reliable and valid marker-less motion capture device. HYPOTHESIS The Kinect V2 will demonstrate good to excellent correlation between KASR results at IC and PF during the DVJ, as compared with a "gold standard" Vicon motion analysis system. STUDY DESIGN Descriptive laboratory study. LEVEL OF EVIDENCE Level 2. METHODS Thirty-eight healthy volunteer subjects (20 male, 18 female) performed 5 DVJ trials, simultaneously measured by a Vicon MX-T40S system, 2 AMTI force platforms, and a Kinect V2 with customized software. A total of 190 jumps were completed. The KASR was calculated at IC and PF during the DVJ. The intraclass correlation coefficient (ICC) assessed the degree of KASR agreement between the Kinect and Vicon systems. RESULTS The ICCs of the Kinect V2 and Vicon KASR at IC and PF were 0.84 and 0.95, respectively, showing excellent agreement between the 2 measures. The Kinect V2 successfully identified the KASR at PF and IC frames in 182 of 190 trials, demonstrating 95.8% reliability. CONCLUSION The Kinect V2 demonstrated excellent ICC of the KASR at IC and PF during the DVJ when compared with the Vicon system. A customized Kinect V2 software program demonstrated good reliability in identifying the KASR at IC and PF during the DVJ. CLINICAL RELEVANCE Reliable, valid, inexpensive, and efficient screening tools may improve the accessibility of motion analysis assessment of adolescent female athletes.
