Predictors of Academic Productivity Among Spine Surgeons.

INTRODUCTION: The relationship between research productivity in training and future productivity as an attending spine surgeon is not well-established in the literature nor has the effect of geographic location of training institutions on future academic success been investigated. The aim of our study was to (1) summarize characteristics of academically productive spine surgeons, (2) assess predictors of long-term academic productivity, and (3) establish the effect of geographic location on long-term academic productivity. METHODS: A query was conducted of the 2021 to 2022 North American Spine Society Spine Fellowship Directory of all orthopaedic and neurosurgical spine fellowship selection committee members for each institution participating in the spine fellowship match. The attending publication rate and h- index were determined. A multivariate linear regression model was developed. P value was set to <0.05. RESULTS: We identified 310 orthopaedic and neurosurgical spine surgeons, representing 76 fellowship programs. Multivariate linear regression analysis identified that the publications during residency ( P < 0.001) and during fellowship ( P < 0.001) were significant predictors of an increased publication rate as an attending surgeon. By contrast, the preresidency publication rate ( P = 0.729) was not significantly predictive of the attending publication rate. Multivariate analysis of h- index found that residency publication rate had a positive correlation ( P = 0.031) compared with preresidency ( P = 0.579) or fellowship ( P = 0.257) rates. Attendings who had attended residency in the Northeast and currently practicing in the Northeast had a higher publication rate ( P < 0.001 and P = 0.004, respectively). DISCUSSION: A higher number of publications in residency and fellowship were markedly predictive of an increased publication rate as an attending spine surgeon. By contrast, preresidency publications may not be indicative of future academic productivity as an attending. Location may also contribute to attending publication rate and favor those who undergo residency training and ultimately practice in the Northeast.

Increased rates of subjective shoulder instability after Bankart repair with remplissage compared to Latarjet surgery.

HYPOTHESIS AND BACKGROUND: Controversy exists as to the ideal management of young active patients with subcritical glenoid bone loss and an off-track Hill-Sachs lesion, and the Latarjet and arthroscopic Bankart with remplissage are effective surgical options. The purpose of this study was to compare rates of recurrent instability and reoperation, as well as patient-reported outcome measures, between Latarjet and arthroscopic Bankart repair with remplissage surgery patients. The authors hypothesized that there would be no difference in rates of recurrent instability, reoperation, and postoperative outcomes between patients who underwent Latarjet surgery and patients who underwent Bankart repair with concomitant remplissage postoperatively. MATERIALS AND METHODS: All patients who underwent primary shoulder stabilization for shoulder instability from 2014 to 2019 were screened. Latarjet and Bankart repair with remplissage patients were included if arthroscopic surgery was performed in response to anterior shoulder instability. Recurrent instability, revision, shoulder range of motion, return to sport (RTS), and patient-reported outcome measures (Oxford Shoulder Instability, Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form scores) were compared between groups. RESULTS: Overall, 43 Latarjet patients (age: 29.8 ± 12.1 years, 36 males 7 females) and 28 Bankart repair with remplissage patients (age: 28.2 ± 8.8 years, 25 males 3 females) were included with a mean follow-up of 3.3 ± 1.9 years. Patients who underwent Latarjet surgery had larger amounts of bone loss (19% vs. 11%, P < .001), a lower rate of off-track Hill-Sachs lesions (47% vs. 82%, P < .001), and more frequently had a history of chronic shoulder dislocations (88% vs. 43%, P < .001) compared to Bankart repair with remplissage patients. Latarjet patients less frequently reported feeling subjective shoulder instability after surgery (21% vs. 50%, P = .022), which was defined as feeling apprehension or experiencing a shoulder subluxation or dislocation event. There were no differences in rates of postoperative dislocation, revision, reoperation, or RTS, as well as patient-reported outcome scores, between groups (all P > .05). CONCLUSION: Despite differences in osseous defects, Latarjet and Bankart repair with remplissage patients had similar rates of clinical, patient-reported, and RTS outcomes at a mean of 3.3 years postoperatively. Latarjet surgery patients may be less likely to experience subjective shoulder instability postoperatively than patients who undergo Bankart repair with concomitant remplissage.

Comparison of post-operative outcomes following anterior cruciate ligament reconstruction between patients with vs. without elevated tibial tubercle-trochlear groove (TT-TG) distance.

PURPOSE: It is unclear if an elevated tibial tubercle-trochlear groove (TT-TG) distance is a risk factor for poor outcomes following ACLR. Therefore, the purpose of this study was to determine whether patients with an elevated TT-TG have an increased risk of retear following primary ACLR compared to controls with a normal TT-TG. METHODS: All patients who underwent primary ACLR between July 2018 and June 2019 with an available preoperative magnetic resonance imaging (MRI) were eligible for inclusion. TT-TG distance was measured on preoperative MRI scans by two independent investigators. Clinical outcomes, return-to-sport rates, and Lysholm scores were compared between patients with a TT-TG < 12.5 mm (normal) and those with a TT-TG ≥ 12.5 mm (elevated). RESULTS: Overall, 159 patients were included, 98 with normal TT-TG distance and 61 with elevated TT-TG distance. Patients with an elevated TT-TG distance had worse post-operative Lysholm scores than patients with a normal TT-TG distance (83.0 vs. 95.0, p = 0.010). In patients who received a bone-patellar tendon-bone (BTB) graft, an elevated TT-TG distance was associated with higher rates of subjective instability (13.0% vs. 3.0%, p = 0.041), reoperation (13.0% vs. 1.5%, p = 0.012), and post-operative complications (25.0% vs. 8.2%, p = 0.026), as well as lower ACL psychological readiness scores (324.1 vs. 446.7, p = 0.015). CONCLUSION: Patients with an elevated pre-operative TT-TG distance have worse Lysholm scores than patients with normal TT-TG distance. Patients with an elevated pre-operative TT-TG distance who underwent ACLR with BTB grafts had significantly higher rates of subjective instability, reoperation, and post-operative complications.

Analysis of Musculoskeletal Injuries Among Collegiate Varsity Electronic Sports Athletes.

Background Collegiate electronic sports (esports) in the United States has grown from seven varsity programs in 2016 to over 200 today. Despite its growing success, little has been studied on the injuries of these athletes. In this study, we aimed to investigate the prevalence of injuries sustained by collegiate esports players and explore the injuries' impacts on their careers. The authors hypothesized that athletes who spend more time practicing and playing competitively in esports will report an increased history of musculoskeletal injury. Methodology This was a cross-sectional study, level IV evidence. A list of collegiate esports athletes was collected from publicly available sources. Athletes with available contact information were sent a self-reporting questionnaire. The questionnaire examined variables including length of time playing esports, hours/day playing esports, esports-related injury history, surgeries needed, and missed competition time. Results Overall, 153 collegiate esports athletes (88% male, aged 18-42 years) were included, with 41 (26.8%) having experienced at least one injury from esports. Of the 41 injured athletes, three (7.3%) required surgery, 17 (41.5%) had multiple injuries, and seven (17.1%) missed competition time for an average of 3.0 ± 2.3 weeks. Athletes who have been on their respective college team longer (2.0 ± 1.0 vs. 1.7 ± 0.9 years, p = 0.03) and who spent more hours per day practicing had a higher injury incidence (p = 0.01). There was no difference in the current age, sex, age at which athletes began competing in esports, and scholarship status between groups (all p > 0.05). When analyzing the 41 athletes who experienced an injury, the most common injury was to the wrist with 25 total injuries. There were 11 neck, 10 back, nine finger, eight hand, six elbow, and four thumb injuries. Conclusions Collegiate esports players who trained for more hours per day (31.7% of injured players vs. 10.7% of uninjured players practiced more than five hours/day, p = 0.01) and played competitive collegiate esports for more years (2.0 ± 1.0 vs. 1.7 ± 0.9 years, p = 0.03) were more likely to have experienced an esports-related injury. Fortunately, only a small portion of athletes who experienced an injury was forced to miss competition time or require surgery. With this being the largest investigation into collegiate esports-related injuries, future medical research regarding the incidence, management, and prevention of its injuries can help collegiate and professional programs place a greater emphasis on the health of their athletes.

Effect of Preoperative MRI Coracoid Dimensions on Postoperative Outcomes of Latarjet Treatment for Anterior Shoulder Instability.

Background: Preoperative coracoid dimensions may affect the size of the bone graft transferred to the glenoid rim and thus the postoperative outcomes of Latarjet coracoid transfer. Purpose: To determine the effect of coracoid length and width as measured on preoperative magnetic resonance imaging (MRI) on outcomes after Latarjet treatment of anterior shoulder instability. Study Design: Cohort study; Level of evidence, 3. Methods: Included were patients who underwent primary Latarjet surgery between 2009 and 2019 and had preoperative MRI scans and minimum 2-year postoperative outcomes. Longitudinal coracoid length was measured on axial MRI sequences as the distance from the coracoclavicular ligament insertion to the distal tip. Comparisons were made between shorter and longer coracoids and between narrower and wider coracoids. The outcomes of interest were recurrent instability, reoperation, complications, return to sport (RTS), and American Shoulder and Elbow Surgeons (ASES) score. Independent-samples t test, Mann-Whitney test, chi-square test, and Fisher exact test were used to compare outcomes between groups, and univariate correlation coefficients were calculated to evaluate the relationships between demographics and coracoid dimensions. Results: Overall, 56 patients were included (mean age, 28.4 years). The mean ± SD coracoid length was 21.6 ± 2.4 mm and width 10.0 ± 1.0 mm. Relative to patients with a longer coracoid (≥22 mm; n = 26), patients with a shorter coracoid (<22 mm; n = 30) had similar rates of recurrent instability (shorter vs longer; 6.7% vs 3.8%), complications (10.0% vs 15.4%), reoperation (3.3% vs 7.7%), and RTS (76.5% vs 58.8%) and similar postoperative ASES scores (85.0 vs 81.6) (P ≥ .05 for all). Likewise, relative to patients with a wider coracoid (≥10 mm; n = 27), patients with a narrower coracoid (<10 mm; n = 29) had similar prevalences of recurrent instability (narrower vs wider; 6.9% vs 3.7%), complications (17.2% vs 7.4%), reoperation (3.5% vs 7.4%), and RTS (66.7% vs 68.4%) and similar postoperative ASES scores (87.1 vs 80.0) (P ≥ .05 for all). Conclusion: Patients undergoing Latarjet coracoid transfer had similar postoperative outcomes regardless of preoperative coracoid dimensions. These findings should be confirmed in a larger cohort before further clinical recommendations are made.

Knotted Versus Knotless Medial-Row Transosseous-Equivalent Double-Row Rotator Cuff Repairs Have Similar Clinical and Functional Outcomes.

Purpose: To retrospectively investigate the clinical and functional outcomes of patients who underwent knotted medial-row rotator cuff repair (KT-RCR) compared with patients who underwent knotless medial-row rotator cuff repair (KL-RCR). Methods: A retrospective chart review of patients who underwent double-row transosseous-equivalent rotator cuff repair in 2016 was performed at a single institution with 2-year follow-up. Information regarding demographic characteristics, preoperative tear size (magnetic resonance imaging), surgical variables (including method of suture stabilization), preoperative and postoperative American Shoulder and Elbow Surgeons (ASES) scores, and all complications (e.g., cuff failure, adhesive capsulitis, and persistent pain) was compiled. Results: A total of 189 patients met the inclusion criteria: 72 in the KL-RCR group and 117 in the KT-RCR group. No significant difference in preoperative ASES scores was found between the KL-RCR and KT-RCR groups (48.3 vs 45.4, P = .327). Postoperative ASES scores did not differ between the groups (82.4 for KL-RCR vs 78.8 for KT-RCR, P = .579). We found no significant difference in cuff failure rates after 2 years, determined by magnetic resonance imaging (5.6% for KL-RCR vs 6.1% for KT-RCR, P > .999), or complication rates (11.1% for KL-RCR vs 8.6% for KT-RCR, P = .743). Conclusions: The knotted approach and knotless approach to double-row rotator cuff repair showed similar outcome scores, cuff failure rates, and complication rates at minimum 2-year follow-up. Level of Evidence: Level III, retrospective therapeutic comparative trial.

What Are the All-Cause Survivorship Rates and Functional Outcomes in Patients Younger Than 55 Years Undergoing Primary Knee Arthroplasty? A Systematic Review.

BACKGROUND: Approximately one-fourth of TKAs will be performed in patients 55 years or younger within the next decade. Postoperative outcomes for younger patients who had a knee arthroplasty were systematically reviewed in 2011; however, numerous studies evaluating young patients who had both a TKA and unicompartmental knee arthroplasty (UKA) have been reported in the past decade. Therefore, to better counsel this growing population of young patients undergoing knee arthroplasty, an updated understanding of their expected postoperative outcomes is warranted. QUESTIONS/PURPOSES: In this systematic review, we evaluated (1) all-cause survivorship, (2) reasons for revision, (3) patient-reported outcomes, and (4) return to physical activity and sport in patients 55 years or younger undergoing primary TKA or UKA. METHODS: A comprehensive search of PubMed, Medline, SportDiscus, and CINAHL was performed to identify all original studies evaluating outcomes after primary knee arthroplasty for young patients (55 years of age or younger) from inception until March 2021. The following keywords were used: knee, arthroplasty, replacement, pain, function, revision, survivorship, sport, physical activity, and return to play. Only original research studies that were related to knee arthroplasty and reported postoperative outcomes with a minimum 1-year follow-up for patients 55 years or younger were included. Unpublished materials, publications not available in English, and studies with a primary diagnosis of rheumatoid arthritis were excluded. The Methodological Index for Non-Randomized Studies (MINORS) score was used to evaluate the study quality of case series and comparative studies, while the Cochrane Risk of Bias tool and the Jadad scale were used for randomized studies. The primary outcomes of interest for this study were all-cause survivorship rate, reasons for all-cause revision, Knee Society and Knee Society Function scores (minimum clinically important difference [MCID] 7.2 and 9.7, respectively), WOMAC scores (MCID 10), Tegner scores (no reported MCID for knee arthroplasty), and return to physical activity or sport. Knee Society and Knee Society Function scores range from 0 to 100, with scores from 85 to 100 considered excellent and below 60 representing poor outcomes. All-cause survivorship rate and reasons for revision were both reported in 17 total studies. Knee Society scores were presented in 19 and Knee Society Function scores were reported in 18 included studies. WOMAC scores and Tegner scores were each found in four included studies, and return to physical activity and return to sport analyses were performed in seven studies. Overall, 21 TKA studies and five UKA studies were included in this analysis, featuring 3095 TKA knees and 482 UKA knees. RESULTS: Kaplan-Meier estimates of all-cause survivorship ranged from 90% to 98% at 5 to 10 years of follow-up after TKA and from 84% to 99% (95% CI 93% to 98%) at 10 years to 20 years post-TKA. All-cause UKA survivorship was 90% at 10 years and 75% at 19 years in the largest Kaplan-Meier estimate of survivorship for patients younger than 55 who underwent UKA. Common reasons for revision in TKA patients were polyethylene wear/loosening, aseptic tibial loosening, and infection, and in UKA patients the common reasons for revision were knee pain, aseptic loosening, progression of knee osteoarthritis, and polyethylene wear/loosening. Knee Society scores ranged from 85 to 98 for 5-year to 10-year follow-up and ranged from 86 to 97 at 10-year to 20-year follow-up in TKA patients. Knee Society Function scores ranged from 70 to 95 for 5-year to 10-year follow-up and ranged from 79 to 86 at 10-year to 20-year follow-up. Return to physical activity and sport was reported variably; however, most patients younger than 55 have improved physical activity levels after knee arthroplasty relative to preoperative levels. CONCLUSION: Although all-cause survivorship rates were frequently above 90% and patient-reported outcome scores were generally in the good to excellent range, several studies reported long-term survivorship rates from 70% to 85% and fair patient-reported outcome scores, which must be factored into any preoperative counseling with patients. We could not control for surgeon volume in this report, and prior research suggests that increasing volume is associated with less frequent complications; in addition, the studies we included were variably affected by selection bias, transfer bias, and assessment bias, which makes it likely that the findings of our review represent best-case estimates. To limit the frequency of revision in patients younger than 55 years undergoing TKA, clinicians should be cautious of polyethylene wear/loosening, aseptic tibial loosening, and infection, while knee pain and progression of knee osteoarthritis are also common reasons for revision in patients younger than 55 undergoing UKA. Further research should isolate younger knee arthroplasty patients and evaluate postoperative activity levels while accounting for preoperative physical activity and sport participation. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Avascular Necrosis and Atraumatic Anterior Dislocation of the Femoral Head During Pregnancy: A Case Report.

CASE: This report describes a case of bilateral femoral head avascular necrosis during pregnancy with a subsequent anterior dislocation of the femoral head during labor in a 40-year-old woman. CONCLUSIONS: Many physiologic and hormonal changes occur during pregnancy. Although rare, hip pathologies may cause life-changing health outcomes, demonstrating a need for more research and careful monitoring throughout pregnancy.

Using Illness Rating Systems to Predict Discharge Location Following Total Knee Arthroplasty.

PURPOSE: Total knee arthroplasty (TKA) is increasing in frequency and cost. Optimization of discharge location may reduce total expenditure while maximizing patient outcomes. Although preoperative illness rating systems-including the American Society for Anesthesiologists Physical Classification System (ASA), severity of illness scoring system (SOI), and Mallampati rating scale (MP)-are associated with patient morbidity and mortality, their predictive value for discharge location, length of stay (LOS), and total costs remains unclear. MATERIALS AND METHODS: We conducted a retrospective analysis of 677 TKA patients (550 primary and 127 revision) treated at a single institution. The influence of ASA, SOI, and MP scores on discharge locations, LOS, and total costs was assessed using multivariable regression analyses. RESULTS: None of the systems were significant predictors of discharge location following TKA. SOI scores of major or higher (ß=2.08 days, p＜0.001) and minor (ß=-0.25 days, p=0.009) significantly predicted LOS relative to moderate scores. Total costs were also significantly predicted by SOI scores of major or higher (ß=$6,155, p=0.022) and minor (ß=-$1,163, p=0.007). CONCLUSIONS: SOI scores may be harnessed as a predictive tool for LOS and total costs following TKA, but other mechanisms are necessary to predict discharge location.
