Mental Health Rather than Mental Disorders as a Predictor of Immediate Postoperative Recovery Following Elective Lumbar Fusion: Using the PROMIS-10 Global Mental Health T-Score.

STUDY DESIGN: Retrospective comparative cohort. OBJECTIVE: Investigate how a patient's mental health, as measured using the PROMIS-10 Global Mental Health T-Score (MHT), influences their in-hospital recovery following elective one to two level lumbar fusion. SUMMARY OF BACKGROUND DATA: The intersection of mental and physical health among candidates for lumbar fusion has increased. While there is strong evidence to suggest mental disorders can influence a patient's postoperative recovery, there is a paucity of information detailing the association between unrecognized low mental health and surgical outcomes. The MHT may provide a more nuanced insight to a patient's preoperative mental health status. METHODS: 637 patients that underwent one or two level elective lumbar fusion between April 2020 and June 2023 were analyzed for this study. Patients were stratified by their MHT (Above Average [AA] >50, control 40-50, Below Average [BA] <40) regardless of mental illness diagnosis. Outcome measures including: pain scores both during activity and at rest, opioid consumption during the in-hospital stay, and ambulation distance were compared among groups using both univariate and multivariate models to control for confounders. RESULTS: The majority of patients reported average (41.4%) to above average (35.3%) mental health. After controlling for confounders, findings suggested that patients in the BA group reported higher pain, consumed more opioids, and had shorter ambulation distances than patients in the AA group (P=0.004, P-0.008, and P=0.020 respectively). Patients in the AA group were 84% less likely to be discharged to a facility compared to the BA group (P=0.001). CONCLUSION: The MHT was an independent predictor of immediate postsurgical recovery, while a mental disorder diagnosis was not. A preoperative MHT<40, may represent and additional risk factor that has not previously been identified in patients undergoing elective lumbar fusion.

MRI Features That Contribute to Decision-Making for Treatment of Capitellar OCD Lesions: An Expert Consensus Using the Delphi Method.

Background: Most healthcare providers utilize magnetic resonance imaging (MRI) to assist in diagnosing and treating osteochondritis dissecans (OCD) of the capitellum. However, consensus on imaging features that portend clinically relevant information in the care of these lesions has not been determined. Purpose: To conduct a survey on the MRI features of a capitellar OCD that are salient for clinical decision-making using a classic Delphi protocol. Study Design: A consensus statement. Methods: Invitations to participate were sent to 33 healthcare providers identified as capitellar OCD experts. A classic 3-round survey method was used to gather agreement and consensus on the level of importance for clinical decision-making on 33 MRI features. A concise list of features that guide decision-making on the stability of an OCD lesion and the ability of an OCD lesion to heal with nonoperative care was also identified. Agreement and consensus were determined a priori as ≥66%. Results: Of the 33 identified experts, 20 agreed to participate, and 17 (52%) completed all 3 rounds. Of the 33 MRI features evaluated, 17 reached agreement as important for clinical decision-making by the experts. Consensus was reached for a concise list of MRI features that were significant to decision-making (94%), suggestive of a stable lesion (100%), had the potential to heal with nonoperative treatment (94%), were suggestive of an unstable lesion (100%), and had low potential to heal with nonoperative treatment (88%). Conclusion: This 3-round Delphi process produced consensus on clinically relevant MRI features that contribute to clinical decision-making for capitellar OCD. The results of this study will be used as the basis for an interrater reliability assessment of the identified salient features, creating the foundation for developing a reliable MRI assessment tool rooted in clinical experiences. The development of a standardized assessment of capitellar OCD is intended to improve clinical practice and patient outcomes.

Positive Deviance and Exploring the Role of Mental Health on Early Postoperative Recovery After Total Hip Arthroplasty: A Retrospective Analysis Using the PROMIS-10 Global Health.

INTRODUCTION: Mental illnesses are well-known factors that contribute to poor outcomes among total hip arthroplasty (THA) patients. However, a dichotomized mental illness diagnosis may not reflect the complex biopsychosocial factors contributing to a patient's health. Investigating patients who achieve positive outcomes despite having risk factors, known as positive deviants, may help identify protective characteristics and decrease health disparities among this growing population of patients. Using preoperative Mental Health T-scores (MHT) from the PROMIS-10 Global Health questionnaire among patients with a mental illness diagnosis, the purpose of this study was to explore whether patients with above-average MHT, or positive deviants, experienced a different immediate postoperative recovery path compared with patients with below-average MHT. METHODS: This was a retrospective chart review of patients undergoing elective primary THA. Patients with a formal diagnosis of a mental health condition were divided based on their MHT (above average [AA] >50, average [A] 40 to 50, below average [BA] <40). Postsurgical parameters included total opioid consumption, self-reported pain scores, and discharge disposition. RESULTS: A total of 299 patients were analyzed. After controlling for length of stay and type of mental illness, patients in the AA-MHT and A-MHT groups used 33.8 and 29.8 morphine milligram equivalents less than patients in the BA-MHT group during the inpatient stay, respectively. Patients in the AA-MHT group reported a 1.0 lower pain with activity score at discharge compared with patients in the BA-MHT group. DISCUSSION: The intersection between patients with a mental illness in need of a THA is becoming more commonplace. Data suggest that patients with a mental illness who report AA-MHT on the PROMIS-10 Global Health questionnaire may represent positive deviants or those with a more positive in-hospital recovery path compared with those patients with BA-MHT. LEVEL OF EVIDENCE: Diagnostic study-retrospective cohort study.

Influence of Anxiety and Depression on Opioid Use Following Lumbar Spine Fusion: A Large Database Study.

STUDY DESIGN: Retrospective database. OBJECTIVE: The purpose of this study was to understand how a mental health disorder, specifically anxiety and depression, influences a patient's postoperative opioid needs following single-level lumbar spine fusion. SUMMARY OF BACKGROUND DATA: Patients with spine pathology commonly demonstrate symptoms of an active psychiatric disorder. Mental health significantly influences how a patient perceives pain and a patient's opioid pain control needs after surgery. MATERIALS AND METHODS: The Pearldiver Patient Claims Database was used to identify patients undergoing single-level posterior spine fusion within the United States between 2010 and 2020. Patients were placed into 1 of 4 groups: those with a diagnosis of depression, those with a diagnosis of anxiety, those with a diagnosis of both anxiety and depression, and a control group. χ 2 tests were used to assess differences in the number of patients filling initial and additional opioid prescriptions for up to 90 days following their fusion. RESULTS: The control group filled significantly more initial opioid prescriptions within the first 90 days following their spine fusion ( P <0.001). However, there was no difference among the study groups in regard to the additional need for prescriptions. CONCLUSION: Patients with mental health diagnoses may present as complex patients to spine surgeons; however, this study suggests they do not require additional opioid pain control following a single-level lumbar fusion.

Influence of Anxiety and Depression on Opioid Use After Cervical Spine Fusion: An Analysis of a National Claims Database.

Patients with spine pathology demonstrate an above average rate of active psychiatric disorders, which can influence their recovery. This study was designed to understand how mental health diagnoses (ie, anxiety and depression) influence a patient's postoperative need for opioids after a single level cervical spine fusion. The PearlDiver database was used to identify patients. Patients were placed into one of four groups: those with a diagnosis of depression, those with a diagnosis of anxiety, those with a diagnosis of both anxiety and depression, and a control group. Chi-square tests were used to assess differences in the number of patients filling initial and additional opioid prescriptions for up to 90 days after their fusion. A total of 168,967 patients who underwent an elective cervical spine fusion in the United States between 2010 and 2021 were included in this study. The control group filled significantly more opioid prescriptions within the first 90 days after their cervical fusion (P<.001). There was no difference among the study groups regarding the need to fill additional opioid prescriptions. Patients with a diagnosis of depression and/or anxiety may present as complex patients; however, results suggest they do not need additional opioids for pain control after a single level cervical spine fusion.

Low Body Mass Index Patients Undergoing an Anterior Lumbar Fusion May Have an Increased Risk of Perioperative Complications.

BACKGROUND: Previous research has shown that underweight patients may be at a greater risk of experiencing postsurgical complications. The purpose of this study was to investigate the association between body mass index (BMI) and postoperative complications following single-level anterior lumbar fusion (ALF). METHODS: All single-level elective ALF procedures performed between 2010 and 2020 were identified in the PearlDiver Mariner Database. Patients were separated into 6 groups based on the World Health Organization BMI classifications. Differences in postsurgical complications (ie, deep vein thrombosis, pulmonary embolism, surgical site infection, hardware malfunction, wound dehiscence, and blood transfusion) among BMI categories were assessed using a χ2 contingency test. RESULTS: Results indicated that underweight patients (BMI <20) were at a significantly greater risk of developing deep vein thromboses, experiencing hardware malfunction, and requiring blood transfusion compared with any other BMI classification (P < 0.001). Results also demonstrated that underweight individuals had similar risks of developing surgical site infection and wound dehiscence compared with patients classified as having obesity class III. CONCLUSION: Underweight patients may be at a greater risk than currently believed of experiencing postoperative complications following single-level ALF procedures. CLINICAL RELEVANCE: Patients with a BMI of 20 or less should be carefully evaluated prior to surgical intervention to ensure they are optimized for surgery.

The effect of cannabis use on postoperative complications in patients undergoing spine surgery: A national database study.

Background: With the increased use of cannabis in the US, there is a significant need to understand the medical complications associated with its use in relationship to a surgical population. Cannabis has mainly been studied with respect to its qualities of pain treatment, yet few studies have investigated post-surgical complications associated with its use. Therefore, the purpose of this study was to explore the effect of cannabis use on complications in spine surgery, and compare these complications rates to opioid-related complications. Methods: This was a retrospective study conducted using the PearlDiver Database. Using ICD codes 40,989 patients that underwent lumbar spine fusion between January 2010 and October 2020 were identified and divided into 3 study groups (i.e., control, patients with known opioid use disorder, and patients identified as cannabis users). Differences in the incidence of complications within 30 days of the index procedure and pseudarthrosis rates at 18 months postindex procedure were assessed among study groups using a multivariate logistic regression. Results: Of 12.4% study population used cannabis and 38.8% had a known opioid use disorder. Results indicated increased odds of experiencing a VTE, hypoxia, myocardial infarction, and arrhythmia for both opioid and cannabis users compared to controls; however, when controlling for tobacco use there were no increased odds of complications within the cannabis group. The pseudarthrosis rate was greater in cannabis users (2.4%) than in controls (1.1%). Conclusions: The pseudarthrosis rate was significantly greater in patients using cannabis and opioids compared to the control group. However, when controlling for tobacco use, results suggested a possible negative synergistic between cannabis use and concomitant tobacco use that may influence bone fusion.

Cannabis use is associated with decreased opioid prescription fulfillment following single level anterior cervical discectomy and fusion (ACDF).

Background: Recently, there has been increasing legalization of marijuana within the United States, however data are mixed with respect to its efficacy in treating acute pain. Our goal was to identify a difference in opioid utilization in patients with known cannabis use before anterior cervical discectomy and fusion (ACDF) compared with those that report no cannabis use. Methods: This study was a retrospective case-control design using PearlDiver. Patients who underwent a single level ACDF between January 2010 and October 2020, were included. Patients were placed in the study group if they had a previous diagnosis of cannabis use, dependence, or abuse. Patients were excluded if they were under the age of 18 or if they had filled an opioid prescription within 3 months of their procedure. A control group was then created using a propensity score match on age, gender, and Charleston comorbidity index (CCI), and had no diagnosis of cannabis use. The primary outcome was the number of morphine milliequivalents (MME) dispensed per prescription following surgery. Results: A total of 1,339 patients were included in each group. The number of patients filling prescriptions was lower in the cannabis group than in the control group at 3 days postoperatively (p<.001). The average total MME per day as prescribed was lower in the cannabis group than the control group at 60 days post-op (48.5 vs. 59.4, respectively; p=.018). Conclusions: Patients who had a previous diagnosis of cannabis use, dependence or abuse filled fewer opioid prescriptions postoperatively (at 3 days postoperatively) and required lower doses (reduced average daily MME, at 60 days postoperatively) when compared with the control group.

Reliability of Radiographic Imaging Characteristics for Osteochondritis Dissecans of the Capitellum.

BACKGROUND: A primary challenge in the treatment of capitellar osteochondritis dissecans (OCD) is accurate imaging assessment. Radiographic classification consensus is not available in the current literature, and correlation of radiographs with lesion stability and resultant best treatment is lacking. PURPOSE: To determine the inter- and intrarater reliability of the presence or absence and common radiographic characteristics of capitellar OCD lesions. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 3. METHODS: Anteroposterior, lateral, and oblique radiographs for 29 cases were reviewed by 7 orthopaedic surgeons. Images were assessed for elbow anthropometry and morphology, OCD presence, lesion characteristics, the presence of progeny bone and progeny features, and radial head abnormalities. Intra- and interrater reliability was assessed using Fleiss and Cohen kappa for nominal variables and intraclass correlation coefficients (ICCs) for continuous variables. RESULTS: Surgeons demonstrated substantial to excellent inter- and intrarater reliability when assessing elbow characteristics: anthropometric (interrater ICC, 0.94-0.99; intrarater ICC, 0.82-0.96) and morphologic (Fleiss, 0.61-0.76; Cohen, 0.68). When the OCD lesion was assessed, fair to moderate interrater agreement was found for classifying the absence or presence of a lesion (Fleiss, 0.28-0.46) and the location of the OCD (Fleiss, 0.24-0.52), poor agreement for assessing the contour of the lesion (Fleiss, 0.00-0.09), and excellent agreement for measuring the size of the lesion (ICC, 0.82-0.94). Poor to fair interrater agreement was found for radial head abnormalities (Fleiss, 0.00-0.27). Progeny bone visualization and fragmentation demonstrated moderate interrater agreement (Fleiss, 0.43-0.47) where displacement of the bone demonstrated poor interrater agreement (Fleiss, 0.11-0.16). Intrarater agreement for OCD lesion characteristics, progeny bone visualization, and progeny bone features was moderate to excellent. CONCLUSION: Given only the fair to moderate agreement among raters for identifying OCD on radiographs, this imaging modality may not serve as a dependable screening tool in isolation. Additional imaging should be obtained if the clinical presentation suggests capitellar OCD and a definitive diagnosis is not possible with radiographs. However, clinicians can reliability measure the size of radiographically apparent OCD, suggesting that radiographs may serve as an appropriate imaging modality for follow-up care.

Descriptive Epidemiology From the Research in Osteochondritis Dissecans of the Knee (ROCK) Prospective Cohort.

BACKGROUND: Osteochondritis dissecans (OCD) occurs most commonly in the knees of young individuals. This condition is known to cause pain and discomfort in the knee and can lead to disability and early knee osteoarthritis. The cause is not well understood, and treatment plans are not well delineated. The Research in Osteochondritis Dissecans of the Knee (ROCK) group established a multicenter, prospective cohort to better understand this disease. PURPOSE: To provide a baseline report of the ROCK multicenter prospective cohort and present a descriptive analysis of baseline data for patient characteristics, lesion characteristics, and clinical findings of the first 1000 cases enrolled into the prospective cohort. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Patients were recruited from centers throughout the United States. Baseline data were obtained for patient characteristics, sports participation, patient-reported measures of functional capabilities and limitations, physical examination, diagnostic imaging results, and initial treatment plan. Descriptive statistics were completed for all outcomes of interest. RESULTS: As of November 2020, a total of 27 orthopaedic surgeons from 17 institutions had enrolled 1004 knees with OCD, representing 903 patients (68.9% males; median age, 13.1 years; range, 6.3-25.4 years), into the prospective cohort. Lesions were located on the medial femoral condyle (66.2%), lateral femoral condyle (18.1%), trochlea (9.5%), patella (6.0%), and tibial plateau (0.2%). Most cases involved multisport athletes (68.1%), with the most common primary sport being basketball for males (27.3% of cases) and soccer for females (27.6% of cases). The median Pediatric International Knee Documentation Committee (Pedi-IKCD) score was 59.9 (IQR, 45.6-73.9), and the median Pediatric Functional Activity Brief Scale (Pedi-FABS) score was 21.0 (IQR, 5.0-28.0). Initial treatments were surgical intervention (55.4%) and activity restriction (44.0%). When surgery was performed, surgeons deemed the lesion to be stable at intraoperative assessment in 48.1% of cases. CONCLUSION: The multicenter ROCK group has been able to enroll the largest knee OCD cohort to date. This information is being used to further understand the pathology of OCD, including its cause, associated comorbidities, and initial presentation and symptoms. The cohort having been established is now being followed longitudinally to better define and elucidate the best treatment algorithms based on these presenting signs and symptoms.

Male and Female Adolescent Athletes' Readiness to Return to Sport After Anterior Cruciate Ligament Injury and Reconstruction.

OBJECTIVE: The purpose of this study was to examine whether readiness to return to sport (RTS) differed between adolescent male and female athletes after anterior cruciate ligament reconstruction (ACLR). DESIGN: Longitudinal, prospective cohort. SETTING: Outpatient office associated with tertiary-care hospital. PATIENTS: A total of 93 adolescent athletes, 17 years of age and younger, who underwent ACLR surgery with a hamstring autograft were included. INDEPENDENT VARIABLES: Male and female athletes. MAIN OUTCOME MEASURES: Anterior cruciate ligament-return to sport after injury (ACL-RSI) completed at 3 time points: (1) preoperatively (Pre-op), (2) approximately 3 months into rehabilitation (Post-op 1), and (3) during RTS phases of recovery (Post-op 2). RESULTS: There was a significant main effect for both sex (P < 0.010) and time (P < 0.0001) with male athletes having higher ACL-RSI scores than female athletes at all 3 time points; however, there was no significant time by sex interaction. All ACL-RSI scores increased significantly across time, regardless of sex. There were no statistically significant differences between ACL-RSI scores at all 3 time points between individuals who did and did not receive physician clearance. CONCLUSIONS: This study provides a longitudinal depiction of adolescent athletes' readiness to RTS after ACL injury throughout recovery. Both male and female athletes demonstrated diminished ACL-RSI scores before undergoing surgery, with increasing scores at both postoperative time points for both sexes. Overall, female athletes reported lower readiness to RTS at all 3 time points compared with male athletes.

Patient-Reported Outcomes, Return-to-Sport Status, and Reinjury Rates After Anterior Cruciate Ligament Reconstruction in Adolescent Athletes: Minimum 2-Year Follow-up.

BACKGROUND: Significant variation exists in the published rates of return to sport after anterior cruciate ligament (ACL) reconstruction (ACLR). Functional outcomes and psychological response to injury have been implicated as factors that influence return to sport. Most studies focus on patients aged in the mid-20s, and less is known about this topic in adolescents. PURPOSE: To report midterm ACLR results for adolescent patients with regard to return to primary sport, patient-reported outcomes, and reinjury rate. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Adolescent athletes were contacted at a minimum of 2 years after ACLR. Patients completed 2 patient-reported outcome measures, the ACL--Return to Sport After Injury (ACL-RSI) and the International Knee Documentation Committee (IKDC) subjective form, and responded to questions regarding preinjury primary sport and level of competition, post-ACLR return to primary sport status, and reinjury. RESULTS: A total of 74 patients (mean ± SD surgical age, 15.9 ± 1.5 years; follow-up age, 19.9 ± 2.0 years; response rate, 24.5%) completed the surveys at a mean of 4.0 ± 2.0 years after primary ACLR. Outcome scores averaged 90.3 ± 12.3 for IKDC and 81.6 ± 20.4 for ACL-RSI. Questionnaire responses indicated that 27.0% of patients did not return to or sustain primary sport participation after ACLR; the principal reasons were poor knee function, team/training change, and fear of another injury. Both IKDC and ACL-RSI scores were statistically lower in patients who did not successfully return to their primary sport in contrast to patients who successfully resumed their primary sport (IKDC, P = .026; ACL-RSI, P < .001). IKDC and ACL-RSI scores were moderately positively correlated with one another (r Spearman = 0.60). There were 18 patients (reinjury rate, 24.3%) who suffered another ACL injury; 8 of these injuries included ipsilateral ACL graft tear (retear rate, 10.8%). CONCLUSION: In our cohort, 73% of adolescent patients successfully returned to their primary preinjury sport at a minimum of 2 years after ACLR. Both knee function and psychological responses to injury were important in determining an adolescent athlete's return to sport. The findings support the use of the IKDC and ACL-RSI at midterm follow-up, with higher scores associated with a greater likelihood of adolescent patients returning to sport after ACLR.

Osteochondritis Dissecans of the Knee: An Interrater Reliability Study of Magnetic Resonance Imaging Characteristics.

BACKGROUND: Imaging characteristics of osteochondritis dissecans (OCD) lesions quantified by magnetic resonance imaging (MRI) are often used to inform treatment and prognosis. However, the interrater reliability of clinician-driven MRI-based assessment of OCD lesions is not well documented. PURPOSE: To determine the interrater reliability of several historical and novel MRI-derived characteristics of OCD of the knee in children. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: A total of 42 OCD lesions were evaluated by 10 fellowship-trained orthopaedic surgeons using 31 different MRI characteristics, characterizing lesion size and location, condylar size, cartilage status, the interface between parent and progeny bone, and features of both the parent and the progeny bone. Interrater reliability was determined via intraclass correlation coefficients (ICCs) with 2-way random modeling, Fleiss kappa, or Krippendorff alpha as appropriate for each variable. RESULTS: Raters were reliable when the lesion was measured in the coronal plane (ICC, 0.77). Almost perfect agreement was achieved for condylar size (ICC, 0.93), substantial agreement for physeal patency (ICC, 0.79), and moderate agreement for joint effusion (ICC, 0.56) and cartilage status (ICC, 0.50). Overall, raters showed significant variability regarding interface characteristics (ICC, 0.25), progeny (ICC range, 0.03 to 0.62), and parent bone measurements and qualities (ICC range, -0.02 to 0.65), with reliability being moderate at best for these measurements. CONCLUSION: This multicenter study determined the interrater reliability of MRI characteristics of OCD lesions in children. Although several measurements provided acceptable reliability, many MRI features of OCD that inform treatment decisions were unreliable. Further work will be needed to refine the unreliable characteristics and to assess the ability of those reliable characteristics to predict clinical lesion instability and prognosis.

Motion analysis evaluation of adolescent athletes during dual-task walking following a concussion: A multicenter study.

BACKGROUND: Research suggests that dynamic balance in adolescents is compromised following concussion and may worsen if patients return to sport (RTS) too soon. Understanding if there are ongoing dynamic balance deficits in adolescents at the time of RTS clearance would determine if more complex motor tasks are necessary to facilitate safe RTS decisions. RESEARCH QUESTION: The purpose of this study was to determine if there were remaining dynamic balance deficits in concussed adolescents at the time of clearance for RTS. METHODS: Sixteen concussed adolescent athletes (age 14.6 ±â€¯1.8 years; 9 males; 57 ±â€¯46 days post injury) performed a simple walking task as well as two split attention gait tasks (reciting months backwards and audio Stroop). The center of mass (COM) movement and walking velocity during these tasks was compared to a control group of 15 healthy non-concussed adolescent athletes (age 13.8 ±â€¯1.4 years; 9 male). RESULTS: The results indicated that there were no statistically significant differences between the two groups for any of the tasks. Height-normalized walking speed did not differ between groups during walking alone (control: 0.757 ±â€¯0.119, concussed: 0.739 ±â€¯0.108, p = 0.34), with the recitation task (control: 0.555 ±â€¯0.095, concussed: 0.557 ±â€¯0.143, p = 0.72), or with the Stroop task (control: 0.589 ±â€¯0.129, concussed: 0.567 ±â€¯0.141, p = 0.43). Similarly, height-normalized medial-lateral COM displacement did not differ between groups during walking alone (control: 0.027 ±â€¯0.007, concussed: 0.028 ±â€¯0.007, p = 0.98, with the recitation task (control: 0.037 ±â€¯0.012, concussed: 0.0.037 ±â€¯0.016, p = 0.82), or with the Stroop task (control: 0.032 ±â€¯0.014, concussed: 0.033 ±â€¯0.009, p = 0.891). SIGNIFICANCE: These findings indicate that the patients were returned to sport when their dynamic balance was similar to controls suggesting that this cohort had recovered from their concussion. However, large variability in dynamic balance measures in both the patient and control groups may reflect ongoing neuromuscular development and requires further exploration.

Clinical Outcome Measures and Return-to-Sport Timing in Adolescent Athletes After Anterior Cruciate Ligament Reconstruction.

CONTEXT: Multiple factors are likely associated with an adolescent athlete's ability to return to play after anterior cruciate ligament (ACL) reconstruction (ACLR). OBJECTIVE: To investigate the relationship between self-reported and functional outcome measures on return-to-play timing in an adolescent population, in athletes who returned and those who did not return to sport, and to identify a cutoff value for isometric quadriceps strength that could serve as a clinical target for maximizing the odds of returning to play after ACLR. DESIGN: Cross-sectional study. SETTING: Outpatient clinic. PATIENTS OR OTHER PARTICIPANTS: Adolescent athletes who underwent ACLR and completed clinical measures at their 3- and 6-month follow-up appointments were included. MAIN OUTCOME MEASURE(S): Clinical measures included functional outcomes of isometric and isokinetic strength tests and the Anterior Cruciate Ligament Return to Sport After Injury scale and the pediatric version of the International Knee Documentation Committee subjective form. Physician clearance dates for return to play were obtained from patient records. RESULTS: Higher strength measures were associated with better scores on the Anterior Cruciate Ligament Return to Sport After Injury and the pediatric version of the International Knee Documentation Committee instruments at each follow-up. Differences were found in isometric extension strength ( P = .001) and isokinetic extension strength at 180°/s ( P = .03) and 300°/s ( P = .002) between patients who returned to sports and those who did not. A 6-month isometric extension deficit (mean Limb Symmetry Index = 85.48 ± 23.15) displayed high accuracy (area under the curve = 0.82, 95% confidence interval = 0.68, 0.95) for identifying patients who returned to play after ACLR. CONCLUSIONS: Higher strength measures at both 3 and 6 months after ACLR were associated with greater self-reported knee function and greater readiness to return to functional activities at 6 months and ultimately earlier return to sport in adolescent athletes. These results provide evidence that self-reported outcome scores should be used as an additional screening tool in conjunction with quadriceps strength testing to help provide realistic recovery timeframes for adolescent patients.

Do Age and Weightbearing Radiographs Affect Lateral Joint Space and Fibular Height Measurements in Patients With Discoid Lateral Meniscus?

BACKGROUND: Several radiographic parameters have been associated with a discoid lateral meniscus. However, limited information is available regarding the radiographic findings of a discoid meniscus in the pediatric population. PURPOSE: To determine the effect of age and weightbearing (WB) on radiographic parameters associated with discoid lateral menisci in pediatric patients. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: Radiographs of pediatric patients with arthroscopically confirmed lateral discoid menisci were compared with age-, side-, and sex-matched individuals with confirmed normal menisci. Radiographic parameters of lateral joint space width (LJSW) and fibular head height (FHH) were measured by 3 physicians. RESULTS: Significant differences were found between the discoid and control groups when LJSW (P = .002) and FHH (P < .001) were compared. Interrater reliability was good for LJSW (intraclass correlation coefficient [ICC], 0.635) and excellent for FHH (ICC, 0.759). WB radiographs were noted to have better interrater reliability compared with non-WB radiographs for LJSW (ICC, 0.729 vs 0.514, respectively) but had reduced interrater reliability for FHH (ICC, 0.625 vs 0.868, respectively). Subgroup analysis with age stratification indicated that FHH was significantly decreased (indicative of a high fibular head) in the discoid group for all age groups (P < .001 for <10 years and 10-14 years; P = .030 for >14 years); however, LJSW was significantly different only in patients older than 14 years. CONCLUSION: Increased LJSW and FHH were associated with discoid lateral menisci and showed satisfactory interrater reliability. Radiographic evaluation for potential discoid meniscus in pediatric and adolescent patients may be improved by use of fibular height to indicate the presence of a discoid lateral meniscus across age groups, while lateral joint space may be more reliable for older patients.

Anterior Cruciate Ligament Reconstruction in Skeletally Immature Patients: Early Results Using a Hybrid Physeal-Sparing Technique.

BACKGROUND: Reconstruction of the anterior cruciate ligament (ACL) in the skeletally immature patient is frequently performed in hopes of preventing new or additional chondral damage and meniscal injuries. Patients within a few years of skeletal maturity are more at risk for ACL injuries than prepubescent patients, about whom several physeal-sparing techniques have been described. Reconstruction techniques in the former higher risk group need to be better understood. PURPOSE: To review a series of adolescent patients with ACL injuries surgically treated with the hybrid physeal-sparing technique. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Surgical logs of ACL reconstructions (ACLRs) performed at a single pediatric/adolescent sports medicine center over a 6-year period were reviewed. Patients with open physes who had undergone ACLR with a femoral physeal-sparing tunnel and transphyseal tibial tunnel were identified. Their demographics, operative reports, rehabilitative course, time to return to play, outcome scores, and postoperative radiographs were collected and analyzed. RESULTS: Twenty-three patients with a mean chronological age and bone age of 13.0 and 13.6 years, respectively, were identified. Examination and subjective outcome scores were obtained at a mean of 19 months and overall demonstrated positive results, with a mean Pediatric International Knee Documentation Committee (Pedi-IKDC) score of 96.0 and a mean Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) score of 89.1. Full-length mechanical axis films obtained at a mean 21 months postoperatively demonstrated no leg-length discrepancies or angular deformities in 21 of 23 patients. Two patients had an identified growth disturbance in the form of femoral and tibial growth acceleration on the ACL-reconstructed limb. CONCLUSION: The femoral physeal-sparing with transphyseal tibial drilling "hybrid" technique in skeletally maturing patients appears to have a high rate of success with low morbidity. However, the possibility of physeal abnormalities does exist, which demonstrates the importance of a close postoperative follow-up and evaluation until skeletal maturity is achieved. ACLR in skeletally immature patients is performed on an increasingly regular basis. Establishing the best and safest technique to do so is therefore important.

The Biomechanics of Cranial Forces During Figure Skating Spinning Elements.

Several facets of figure skating, such as the forces associated with jumping and landing, have been evaluated, but a comprehensive biomechanical understanding of the cranial forces associated with spinning has yet to be explored. The purpose of this case study was to quantify the cranial rotational acceleration forces generated during spinning elements. This case report was an observational, biomechanical analysis of a healthy, senior-level, female figure skating athlete who is part of an on-going study. A triaxial accelerometer recorded the gravitational forces (G) during seven different spinning elements. Our results found that the layback spin generated significant cranial force and these forces were greater than any of the other spin elements recorded. These forces led to physical findings of ruptured capillaries, dizziness, and headaches in our participant.

Sleep Disturbances in Concussed Athletes: A Review of the Literature.

Adolescents and young adults recovering from a concussion may experience subjective changes in their normal sleeping patterns. These subjective sleep complaints may influence a patient's perceived concussion symptoms and negatively impact cognition and school function. Clinicians should be cognizant of these changes in normal sleeping patterns for adolescent and young adult concussion patient and familiarize themselves with available treatment options.

Impact of Co-management at the Primary-Subspecialty Care Interface on Follow-up and Referral Patterns for Patients With Concussion.

BACKGROUND: Co-management is a collaborative care model that consists of structured tools to define and document care delivered by 2 or more providers. We evaluated the impact of implementing co-management at the interface between pediatric primary care providers (PCPs) and subspecialists. METHODS: Participating PCPs (n = 9) were trained on management of concussion using the co-management tools. Co-managed patients with concussion were prospectively enrolled (n = 148) and compared to a retrospective audit of non-co-managed patients (n = 50). RESULTS: PCPs using co-management demonstrated adherence to the tools. PCPs were significantly more likely to provide follow-up care to patients when using the co-management tools. All participating PCPs reported that co-management enhanced their expertise in caring for patients with concussion. CONCLUSIONS: Co-management can enhance PCPs' capacity to independently manage the care of patients with concussion. Co-management led to an observed change in practice that merits further exploration in terms of cost, quality, and clinical outcomes.
