ABSTRACT

OBJECTIVES: Studies on adherence to neuromuscular training (NMT) for anterior cruciate ligament (ACL) injury prevention are frequently biased due to the use of self-reporting by coaches or the athletes themselves. Few NMT studies use data collectors (aside from the athletes or the individuals administering the NMT program) to decrease bias when assessing the adherence of coaches and sports teams. We hypothesized that the use of a data collector who is independent of the team to evaluate adherence to NMT programs would be reliable. METHODS: In a prior a cluster-randomized controlled trial evaluating adherence to NMT training trial, twelve boys' and nine girls' high school athletic teams in a variety of sports were enrolled. Eight data collectors (unaffiliated with the NMT program) were hired specifically to record adherence of the athletes to the NMT exercises at each team's warm-ups 2-3 times a week, prior to practices and games. In addition to the data collectors, a control group of independent observers made visits throughout the season to also record adherence (solely for the purpose of this study, alongside the data collectors and in the same fashion) in order to evaluate the data collectors' performance and determine inter-observer reliability. The inter-observer reliability between data collectors and independent observers was measured using the Kappa statistic. RESULTS: A total of 399 warm-ups for practices or games were observed by data collectors to obtain adherence data. Independent observers also measured adherence at 58 practices or games for inter-observer reliability. Exercise instruction and alignment cues for 29 different exercises were analysed. The Kappa values ranged from 0.63 to 1.0, indicating substantial to perfect agreement. The overall Kappa values of 0.89 and 0.90 for exercise instruction and alignment cues, respectively, indicated almost perfect agreement. CONCLUSION: The use of a data collector who is independent of the team to evaluate adherence to NMT programs (rather than athlete or coach self-reporting), was shown to be a reliable method for measurement of adherence in studies of NMT for injury prevention. Avoiding self-reporting in adherence research to NMT training may decrease bias. LEVEL OF EVIDENCE: I.

ABSTRACT

BACKGROUND: Treatment for idiopathic adhesive capsulitis of the shoulder remains controversial. Stages 1 to 2 reflect an inflammatory process supporting a rationale for intra-articular glenohumeral joint corticosteroid injection to treat synovial inflammation and prevent progression to capsular fibrosis. HYPOTHESIS: We hypothesize that an intra-articular ultrasound-guided glenohumeral injection (USGI) of corticosteroid in patients diagnosed with Stage 1 or 2 idiopathic adhesive capsulitis will result in timely functional recovery and resolution of pain and stiffness. STUDY DESIGN: Case series. LEVEL OF EVIDENCE: Level 4. METHODS: Patients with Stage 1 or 2 idiopathic adhesive capsulitis treated with an intra-articular corticosteroid injection were included. Patients were seen by a single physician and diagnosed using history and physical examination with careful attention to measurement of glenohumeral range of motion (ROM). A total of 61 patients met inclusion criteria. ROM measurements documented in the patient charts were recorded in forward flexion, abduction, internal rotation, and external rotation in neutral abduction. All ROM measurements were performed pre- and postinjection. All patients were treated with an USGI of local anesthetic and depomedrol. Recovery criteria were defined as forward flexion, abduction, and external rotation within 15° of the contralateral side and internal rotation within 3 spinous process levels of the contralateral side. RESULTS: A total of 11 patients with Stage 1 and 50 patients with Stage 2 adhesive capsulitis comprised the final study cohort. Within the Stage 1 cohort, all 11 patients met recovery criteria for forward flexion and internal rotation (100%), 10 met recovery criteria for abduction (91%), and 8 met recovery criteria for external rotation (73%). Within the Stage 2 cohort, 31 patients met recovery criteria for forward flexion (62%), 30 met recovery criteria for abduction (60%), 36 met recovery criteria for internal rotation (72%), and 25 met recovery criteria for external rotation (50%). The difference in time to recovery in days was statistically significant in all ROM planes and was within 2 to 6 weeks for patients in Stage 1 and 7 to 10 weeks for Stage 2. CONCLUSION: USGI for early adhesive capsulitis allows patients to recover ROM more rapidly if performed early after onset of pain and stiffness. CLINICAL RELEVANCE: These results stress the importance of recognition of idiopathic adhesive capsulitis in its early stages and subsequent intervention with an intra-articular glenohumeral corticosteroid injection.

ABSTRACT

INTRODUCTION: Variations in confidence for procedural skills have been demonstrated when comparing male and female medical students in surgical training. This study investigates whether differences in technical skill and self-reported confidence exist between male and female medical students applying to orthopaedic residency. METHODS: All medical students (2017 to 2020) invited to interview at a single orthopaedic residency program were prospectively evaluated on their technical skills and self-reported confidence. Objective evaluation of technical skill included scores for a suturing task as evaluated by faculty graders. Self-reported confidence in technical skills was assessed before and after completing the assigned task. Scores for male and female students were compared by age, self-identified race/ethnicity, number of publications at the time of application, athletic background, and US Medical Licensing Examination Step 1 score. RESULTS: Two hundred sixteen medical students were interviewed, of which 73% were male (n = 158). No gender differences were observed in suture task technical skill scores or mean difference in simultaneous visual task scores. The mean change from pre-task and post-task self-reported confidence scores was similar between sexes. Although female students trended toward lower post-task self-reported confidence scores compared with male students, this did not achieve statistical significance. Lower self-reported confidence was associated with a higher US Medical Licensing Examination score and with attending a private medical school. DISCUSSION: No difference in technical skill or confidence was found between male and female applicants to a single orthopaedic surgery residency program. Female applicants trended toward self-reporting lower confidence than male applicants in post-task evaluations. Differences in confidence have been shown previously in surgical trainees, which may suggest that differences in skill and confidence may develop during residency training.

ABSTRACT

OBJECTIVES: Women are under-represented in the sports literature despite increasing rates of sports participation. Our objective was to investigate the risks and benefits of an elite women's soccer career in five health domains: general, musculoskeletal, reproductive endocrinology, post-concussion, and mental. METHODS: An online survey was distributed to retired US college, semi-professional, professional, and national team soccer players using personal networks, email, and social media. Short validated questionnaires were used to evaluate the health domains, including the Patient-Reported Outcomes Measurement Information System (PROMIS), Single Assessment Numerical Evaluation (SANE), Post-Concussion Symptom Scale (PCSS), and Patient Health Questionnaire (PHQ). RESULTS: A total of 560 eligible players responded to the survey over a 1-year period. The highest competitive levels were 73% college, 16% semi-professional, 8% professional, and 4% national team. The mean number of years since retirement was 12 (SD = 9), and 17.0% retired for involuntary reasons. The mean SANE scores (0-100 scale as percentage of normal) were knee = 75% (SD = 23), hip = 83% (SD = 23), and shoulder = 87% (SD = 21). The majority (63%) reported that their current activity level included participation in impact sports. A substantial proportion of players reported menstrual irregularities during their careers: 40% had fewer periods with increasing exercise and 22% had no periods for ≥ 3 months. The players (n = 44) who felt that post-concussion symptoms were due to soccer reported more time-loss concussions (F[2] = 6.80, p = 0.002) and symptom severity (F[2] = 30.26, p < 0.0001). Players who recently retired (0-5 years) reported the highest anxiety/depression scores and lowest satisfaction rates compared with those who retired 19+ years ago. CONCLUSION: Health concerns include musculoskeletal injuries, post-concussion symptoms, and lower mental health in the early years following retirement. This comprehensive survey provides initial results that will lay the foundation for further analyses and prioritize research studies that can help all female athletes.

ABSTRACT

Background: Athletes who participate in sports that involve cutting and pivoting movements are particularly susceptible to anterior cruciate ligament (ACL) injury. Preventing this injury is the best way to combat its health consequences and costs. There may be a dose-response relationship between adherence and injury reduction. Purpose: We sought to examine whether athletes' adherence to injury prevention programs (IPPs) is associated with reductions in ACL and lower extremity (LE) injuries. Methods: We conducted a systematic review of the PubMed, EMBASE, and Cochrane Library databases, searching for studies published between 2011 and 2021. Studies were included if they reported on the use of an ACL IPP compared with a control group and recorded the rate of injuries to calculate a rate ratio, as well as adherence to the program as a percentage of sessions performed. For the meta-analysis, the rate ratios were pooled using the DerSimonian-Laird random-effects model. Results: For the 15 studies included (11 randomized controlled trials and 4 cohort studies), the random-effects model grouped athletes' adherence to an IPP as high (76% or more of the sessions), moderate (51%-75% of the sessions), and low (50% or fewer of the sessions). We found that athletes with the highest level of IPP adherence had a significantly lower incidence of ACL injury. The rate ratios for moderate and low adherence did not demonstrate a reduced incidence of ACL injury. Injury prevention program participation was also associated with a decrease in LE injury rates. Conclusion: This systematic review and meta-analysis found that athletes with high adherence to IPPs had reduced rates of ACL and LE injuries. Our findings suggest that educating coaches and athletes on the dose-dependent benefits of IPPs may promote the routine incorporation of these programs into warm-up sessions to decrease the risk of ACL and LE injuries.

ABSTRACT

BACKGROUND: Neuromuscular training (NMT) has demonstrated efficacy as an intervention to decrease the risk of anterior cruciate ligament injuries and improve sports performance. The effect of this training on the mechanisms that contribute to improved physical performance has not been well defined. HYPOTHESIS: Athletes in the NMT group will have better mechanisms of fundamental movements and agility tests that may contribute to improved sports performance. STUDY DESIGN: Prospective cohort study. LEVEL OF EVIDENCE: Level 2. METHODS: Eight high school teams (111 athletes, 53% male, mean age 16 years) participated, with half performing NMT. Physical performance was measured using the dorsaVi ViPerform system, a US Food and Drug Administration-cleared wireless sensor system. Agility was assessed using a timed 3-cone test. Independent sample t tests were used to compare differences between the intervention and control groups. RESULTS: Matched pre- and postseason data were collected from 74 athletes after excluding athletes with injury and those lost to follow-up. Significant improvements were observed in the NMT group for loading/landing speed ratios during a single-leg hop test (right lower extremity = -0.19 [-0.37, 0.03], P = 0.03 and left lower extremity = -0.27 [-0.50, -0.03], P = 0.03). The control group had lower ground reaction forces compared with the NMT group (P < 0.02), while significant improvements were found in the NMT group for initial peak acceleration (P < 0.02) and cadence (P = 0.01) during a straight-line acceleration/deceleration test. For the 3-cone agility test, the postseason time decreased compared with preseason in the NMT group, whereas the time for the control group increased (-0.37 s vs 0.14 s, P < 0.00). CONCLUSION: The results demonstrate that NMT administered by sports medicine clinicians can significantly improve some physical performance of fundamental movements in high school athletes. CLINICAL RELEVANCE: Coaches should be trained to effectively deliver NMT in order to improve sports performance.

ABSTRACT

BACKGROUND: Health disparities related to concussions have been reported in the literature for certain minority populations. Given the significant impact of concussions on long- and short-term function, the mitigation of barriers to accessing care is an important public health objective. OBJECTIVE: To determine if racial and ethnic disparities exist in patients who seek care for concussions compared to a control group with orthopedic ankle injuries (sprains and fractures) to minimize confounding factors that predispose to injury. DESIGN: Cohort study. SETTING: Single institution between February 2016 and December 2020. PATIENTS: A retrospective review of electronic medical records was completed for patients with International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes for concussion, ankle sprain, and ankle fracture. A total of 10,312 patients were identified: 1568 (15.2%) with concussion, 4871 (47.3%) with ankle sprain, and 3863 (37.5%) with ankle fracture. INTERVENTIONS: Patients were stratified by demographic factors, including sex, ethnicity, race, and insurance type. MAIN OUTCOME MEASURES: Diagnosis of concussion. RESULTS: The concussion group was the youngest (28.3 years ± 18.0) and had the fewest females (53.1%) compared to the ankle sprain (35.1 years ± 19.7; 58.7%) and fracture groups (44.1 years ± 21.3; 57.3%). The concussion group had a smaller proportion of Hispanic patients than the ankle sprain group (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.55-0.92, p = .010) and fracture group (OR 0.58, 95% CI 0.44-0.75, p = <.001). In addition, the concussion group was less likely to be Asian (OR 0.70, CI 0.52-0.95, p = .023) than the sprain group and less likely to be Black/African American than both sprain (OR 0.65, 95% CI 0.46-0.93, p = .017) and fracture groups (OR 0.62, 95% CI 0.43-0.89, p = .010). There were no differences across racial groups between ankle sprains and fractures. Patients with Medicaid/Medicare and self-pay had a higher likelihood of being in the concussion group than those with private insurance. CONCLUSION: Differences in concussion diagnosis may exist between certain demographic groups compared to those with ankle injuries. Efforts to mitigate disparities in concussion care are worthwhile with a focus on patient and caregiver education.

ABSTRACT

OBJECTIVE: To compare concussion incidence in male and female soccer players due to the specific concussion-causing activity. METHODS/DATA SOURCES: PubMed, EMBASE, and Cochrane Library were searched for studies published between January 2000 and February 2020. Search terms included 'sex,' 'gender,' 'sex differences,' 'brain injury,' 'sports,' 'athletes,' 'incidence,' 'epidemiology,' 'symptoms,' and 'injury rate.' Studies that contained data on concussion incidence in soccer and featured comparisons by sex and soccer activity were included. Studies that were not written in English, contained data on non-sports-related concussions, or were conference abstracts were excluded. RESULTS: Six studies were included in this meta-analysis, each of which contributed the number of concussions in males and females for a specific soccer activity. Concussion incidence rates were calculated using athlete-exposures as the denominator and a rate ratio was measured by dividing the concussion rate among female soccer players by the rate among male soccer players. Female soccer players were shown to have a greater rate of concussions from heading [1.65 (95% CI: 1.35, 2.03, p < 0.001)] and goalkeeping [1.63 (95% CI: 1.22, 2.17, p = 0.001)]. There were 3 studies comparing sex differences for general play. While the pooled rate ratio was statistically significant [1.51 (95% CI: 1.12, 2.04), p = 0.007], this result was largely driven by 1 study. CONCLUSION: Concussion incidence rates were significantly higher in female soccer players compared to male players while heading. There is also some evidence to suggest that the incidence is higher for female goalkeepers. Soccer coaches and health care providers need to recognize this sex difference when coaching or treating players.

ABSTRACT

OBJECTIVE: To determine the effect of an educational workshop on adherence to neuromuscular training (NMT) among high-school coaches. DESIGN: Cluster-randomized controlled trial. SETTING: High school. PARTICIPANTS: A total of 21 teams in 8 high schools (unit of randomization) were randomized to the intervention or control group. Twelve boys' and 9 girls' teams in a variety of sports were enrolled. INTERVENTION: Coaches in the intervention group participated in a 60-minute education workshop to teach effective implementation of a NMT program and also received print materials. Coaches in the control group received the same print materials. MAIN OUTCOME MEASURES: Eight data collectors were trained to observe each team's practice/game 2 to 3 times a week. They completed a study questionnaire to identify the NMT exercise and whether the coach (1) delivered exercise instructions and (2) provided alignment cues (both yes/no). RESULTS: A total of 399 practices/games were observed over 2 seasons. A greater proportion of coaches in the intervention group provided alignment cues to correct improper technique compared with the control group {difference = 0.04 [95% confidence interval (CI), 0.01-0.07], P = 0.006}. There was a similar proportion of coaches in the intervention and control groups who provided exercise instructions [difference = 0.01 (95% CI, -0.02 to 0.04), P = 0.44]. More coaches in the intervention group completed a full NMT program [OR = 4.62 (1.22, 17.50), P = 0.02]. CONCLUSIONS: Coach education can improve adherence to a NMT program and delivery of alignment cues. Coaches should receive in-person training on NMT and how to deliver alignment cues to their athletes while performing the exercises.

ABSTRACT

Recall bias is a systematic error caused by inaccuracy in reporting past health status and can be a substantial methodological flaw in the retrospective collection of data. Little is known about recall bias following anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to evaluate patients' recall bias regarding preinjury knee function at 2 years after ACLR. METHODS: Patients undergoing ACLR were enrolled in an institutional ACL registry. Preoperatively and at 2 years postoperatively, patients quantified their preinjury knee function on a scale of 0 to 10 (10 = best). Recall bias was quantified as the difference in the reported preinjury function between the 2 time points. The clinical result of ACLR was evaluated according to the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation score. Patients meeting the minimal clinically important difference (MCID) in the IKDC score were considered to have had a good outcome, while patients who did not reach the MCID were considered to have had failure of treatment. Recall bias was compared between the 2 groups. RESULTS: Of 2,109 patients enrolled in the registry, 1,219 were included in the study. Patients with a good outcome remembered their preinjury knee function on a 0-to-10 scale to be better than what they reported at baseline, by a mean difference of 0.40 points (95% confidence interval [CI], 0.22 to 0.58 points). The recall bias was stronger for patients with a poor outcome, who remembered their knee function to be worse than reported at baseline, by a mean difference of -0.81 (95% CI, -1.4 to -0.26). The mean difference in recall between the 2 groups was -1.21 (95% CI, -1.74 to -0.67) (p < 0.0001). CONCLUSIONS: The recall bias of preinjury knee function following ACLR was small and not clinically meaningful for the majority of patients. However, patients with a poor outcome had a clinically relevant and significant recall bias. CLINICAL RELEVANCE: Our findings suggest that patients with a poor outcome have a substantial recall bias. This has clinical relevance when considering treatment effects of revision surgery, whereby the clinical benefit of the treatment might be affected by recall bias.

ABSTRACT

At many institutions, the pendulum has swung toward reverse total shoulder arthroplasty (RTSA). Good results have been reported for patients older than 65 years with glenohumeral osteoarthritis with an intact rotator cuff, leading to questioning of the role of anatomic total shoulder arthroplasty (TSA) in the elderly. The purpose of this study was to compare outcome measures between TSA and RTSA patients using minimal clinically important difference (MCID) and substantial clinical benefit (SCB) as a function of age. Primary TSA or RTSA patients with American Shoulder and Elbow Surgeons (ASES) scores at 2-year follow-up were retrospectively identified from a prospective database. Patients with a diagnosis of inflammatory arthritis, infection, proximal humerus fracture, or revision TSA were excluded. Patients were stratified by age as younger than 65 years, 65 to 74 years, and 75 years or older. A total of 659 TSA and 172 RTSA patients were included. Total shoulder arthroplasty had a larger improvement in ASES scores compared with RTSA in patients aged 65 to 74 years and 75 years and older (P=.04 and P<.01, respectively). In patients aged 75 years or older, the percentages of patients achieving MCID were similar (93.1% TSA and 92.3% RTSA; P=.53); however, a higher percentage of TSA patients achieved SCB vs RTSA patients (90.5% vs 76.9%; P=.01). This study highlights the importance of indications and a shared decision-making model to ensure patient satisfaction. The results support a trend that primary RTSA is a viable option for low-demand patients aged 75 years or older; however, appropriately indicated TSA offers a potential for greater improvement in ASES scores and is more successful at achieving SCB compared with RTSA at 2-year follow-up.

ABSTRACT

BACKGROUND: There is a high incidence of performance-related musculoskeletal disorders in musicians that may be reduced via education programs. However, the efficacy of formalized injury prevention programs has not been rigorously studied. PURPOSE: To assess the feasibility and effect of a formalized injury prevention education workshop on incidence and severity of musculoskeletal pain in a cohort of musician-students attending an intensive summer music festival compared to controls. STUDY DESIGN: Randomized-controlled-pilot trial. METHODS: Musicians at an 8-week long intensive summer festival were randomized to an intervention (workshop) or control group. Workshop attendees participated in a 90-minute session of injury prevention strategies. Musculoskeletal outcome data were collected at the start and end of the festival. Outcomes included presence of musculoskeletal pain, adherence level, and sub-scales of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians. RESULTS: A total of 57 musician-students (ages 17-30, 23 females) participated in the study, and 48(84%) completed the study. Seventy-five percent of workshop participants reported adherence over 8 weeks. At baseline, 84% of participants reported a history of playing-related pain, and 47% recent or current pain. Participants played a range of instruments (50% string, 34% piano, 16% woodwind/brass). At baseline, average weekly reported playing time was 39 hours (±11). At follow-up, reported pain decreased by 32% in the intervention group and increased by 8% in controls (P < .01). Pain interference scores were lower (Post - Pre = -4.58, 95% CI -9.26 to 0.11, P = .055). There was no statistically significant difference between groups for pain intensity. CONCLUSIONS: The high compliance and willingness to participate suggests that injury prevention education implementation is feasible. Our preliminary findings suggest a positive effect on pain incidence and pain interference in the intervention group. Future studies will examine the relationship between adherence levels and injury rates in a larger cohort and identify obstacles to implementation.

ABSTRACT

AIMS: To investigate the impact of the Charlson and Elixhauser comorbidity indices on patient-reported outcomes measures (PROMs) following shoulder arthroplasty. METHODS: Patients undergoing total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), or hemiarthroplasty (HA) from 2016 to 2018 were identified, along with the Charlson and Elixhauser comorbidities listed as their secondary diagnoses in the electronic medical records. Patients were matched to our institution's registry to obtain their PROMs, including shoulder-specific (American Shoulder and Elbow Society (ASES) and Shoulder Activity Scale (SAS)) and general health scales (12-Item Short Form Survey (SF-12) and Patient-Reported Outcomes Measurement Information System-Pain Interference). Linear regression models adjusting for age and sex were used to evaluate the association between increasing number of comorbidities and PROM scores. A total of 1,817 shoulder arthroplasties were performed: 1,017 (56%) TSA, 726 (40%) RSA, and 74 (4%) HA. The mean age was 67 years (SD 10), and 936 (52%) of the patients were female. RESULTS: The most common comorbidities were obesity (1,256, 69%) and hypertension (990, 55%). Patients with more comorbidities had lower ASES and SAS scores at baseline (p < 0.001). Elixhauser comorbidities continued to negatively impact ASES and SAS scores at one year (p = 0.002) and two-year follow-up (p = 0.002). Patients with more comorbidities reported greater pain interference on PROMIS at baseline (p = 0.007), but not at two years. Higher number of Charlson comorbidities were associated with lower scores on the SF-12 mental component at baseline (p < 0.001) and two years (p = 0.020). Higher number of Elixhauser comorbidities were associated with lower SF-12 physical component scores at baseline (p < 0.001) and two years (p = 0.004). CONCLUSION: Higher number of comorbidities was associated with lower baseline scores and worse outcomes on both shoulder-specific and general health PROMs. The presence of specific comorbidities may be used during shared decision-making to manage expectations for patients undergoing shoulder arthroplasty.

ABSTRACT

OBJECTIVES: The appropriateness of neuromuscular training exercises across different age groups has not yet been investigated, particularly in younger children. The purpose of this study was to determine which neuromuscular training exercises can be performed with proper neutral alignment in various age groups. METHODS: Seven exercises were selected for evaluation in children ranging from 8 to 17 years of age who were recruited from schools and youth sports organisations. Participants completed two trials of each exercise and were judged on maintaining neutral body alignment after receiving visual/verbal instruction on the first trial and feedback cues on the second trial. Three evaluators judged each exercise, which was deemed as correct when at least two evaluators agreed that neutral alignment was maintained. Comparisons were made across ages and between sex using the χ² test or Fisher's exact test. The proportions of participants who performed the exercise correctly were also compared before and after feedback cues were provided. RESULTS: A total of 360 participants were evaluated (8-11 years: 165, 54% female; 12-15 years: 136, 40% female, 16-17 years: 59, 53% female). There were no significant differences in performance across ages and sex for nearly all exercises. The majority of children were not able to complete the exercises with proper alignment. The use of feedback cues significantly increased the proportion of participants who correctly completed the exercise (p<0.001). CONCLUSIONS: These results demonstrate the importance of training coaches and physical education teachers to provide cues that reinforce proper technique during anterior cruciate ligament injury prevention exercises. Children should perform common neuromuscular training exercises with feedback on proper technique. LEVEL OF EVIDENCE: IV (case series).

ABSTRACT

BACKGROUND: Nonoperative treatment after first-time patellar dislocation is the standard of care. There is evidence that certain patients may be at high risk for recurrent instability. The aim of this study was to develop a multivariable model to guide management of patients based on their individual risk of recurrent dislocation. METHODS: A multivariable model was developed using 291 patients from 4 institutions to identify which patients were at higher risk for recurrent patellar dislocation within 2 years. This model was informed by a univariable logistic regression model developed to test factors based on the patient's history, physical examination, and imaging. The discriminatory ability of the model to classify who will or will not have a recurrent dislocation was measured using the area under the receiver operating characteristic curve (AUC). RESULTS: Age, a history of a contralateral patellar dislocation, skeletal immaturity, lateral patellar tilt, tibial tubercle-trochlear groove (TT-TG) distance, Insall-Salvati ratio, and trochlear dysplasia were the most important factors for recurrent patellar dislocation. Sex, mechanism of injury, Caton-Deschamps ratio, sulcus angle, inclination angle, and facet ratio were not factors for recurrent dislocation. The overall AUC for the multivariable model was 71% (95% confidence interval [CI]: 64.7% to 76.6%). CONCLUSIONS: Optimizing the management of lateral patellar dislocation will improve short-term disability from the dislocation and reduce the long-term risk of patellofemoral arthritis from repeated chondral injury. This multivariable model can identify patients who are at high risk for recurrent dislocation and would be good candidates for early operative treatment. Further validation of this model in a prospective cohort of patients will inform whether it can be used to determine the optimal treatment plan for patients presenting with an initial patellar dislocation. Until validation of the model is done with new patients, it should not be used in clinical practice. LEVEL OF EVIDENCE: Prognostic Level III.

ABSTRACT

BACKGROUND: Low levels of vitamin D have well-known impacts on bone health, but vitamin D also has a more global role throughout many tissues, including skeletal muscle. The high prevalence of hypovitaminosis D and the vast physiological features of vitamin D have led researchers to examine the influence of vitamin D on physical performance and injury. Because of the critical role of vitamin D in maintaining musculoskeletal health and function, a high rate of hypovitaminosis D among female patients with a variety of musculoskeletal issues could be of high clinical relevance. HYPOTHESIS: There is a high prevalence of low vitamin D in female patients with both acute and overuse sports-related issues of both soft tissue and bone. STUDY DESIGN: Prospective cohort study. LEVEL OF EVIDENCE: Level 3. METHODS: Female patients, aged 16 to 40 years, presenting with lower extremity injury diagnosed within the past 4 weeks, no use of multivitamin or vitamin D supplement, and no history of malabsorption syndrome met the inclusion criteria. Vitamin D levels were assessed and categorized as normal (≥32 ng/mL) and low, which includes insufficient (20.01-31.9 ng/mL) and deficient (≤20 ng/mL). RESULTS: Of the 105 patients enrolled, 65.7% had low vitamin D. Within the low vitamin D cohort, 40.6% were deficient and 59.4% were insufficient. Injuries were grouped into overuse or acute with 74 overuse injuries and 31 acute injuries, exhibiting low vitamin D prevalence of 60.8% and 77.4%, respectively. Patients with ligamentous/cartilaginous injuries exhibited the highest percentage of low vitamin D (76.5%), followed by those with patellofemoral-related complaints (71.0%), muscle/tendon injuries (54.6%), and bone stress injuries (45.5%). In univariable analysis, older age, non-White race, less physical activity, less high-intensity interval training days, less endurance training days, and more rest days showed an association with low vitamin D, but none showed an independent association in multivariable analysis. CONCLUSION: The prevalence of low vitamin D in female patients with various musculoskeletal complaints was high. Clinicians should evaluate for low vitamin D in both acute and overuse injuries. CLINICAL RELEVANCE: In addition to screening, this study suggests that clinicians should evaluate for low vitamin D levels beyond bone stress injuries in the setting of acute and overuse injuries.

ABSTRACT

The goal of this study was to investigate the level of play that can be expected in a young, athletic population after biceps tenodesis and transfer. The authors hypothesized that both return to play rates and clinical improvement would be high after biceps tenodesis and transfer among young athletes. They conducted a retrospective review of patients who underwent biceps tenodesis and transfer procedures with a minimum follow-up of 24 months. Eligible patients were contacted for consent and asked to complete a questionnaire on patient-reported, shoulder-specific outcome measure scores, level of postoperative play, and other relevant information. The study included 41 patients with a mean age of 21.3 years. Patients reported a mean Kerlan-Jobe Orthopaedic Clinic (KJOC) score of 71.7, Disabilities of the Arm, Shoulder and Hand (DASH)-Sports score of 21.3, Single Assessment Numeric Evaluation (SANE) score of 79.4, and Numeric Rating Scale (NRS) pain score of 1.8. Scores for all patient-reported outcome measures were statistically better (P<.05) for patients who underwent biceps transfer (n=24) compared with biceps tenodesis (n=17). Of the participants, 26 (63%) played a primary overhead throwing sport. Most of the patients (95%) returned to play, and of those who returned to play, 67% returned to their preoperative level or higher. Although biceps tenodesis and transfer procedures have been designated primarily for older patients with biceps-labral complex injuries, the high return to play rates and outcome scores of patients in this case series show that biceps tenodesis and transfer can provide effective surgical treatment for a younger athletic population with biceps-labral complex injuries.
