Athlete-Specific Considerations of Cartilage Injuries.

Cartilage injuries can present in a diverse setting of anatomic locations, with varying severity, and can impact athletes of all ages and competition levels. Moreover, the timing of when an injury presents introduces an additional dimension to treatment decision-making. Frequently, the level of competition, in conjunction with career trajectory and short-term and long-term athlete goals, will dictate whether a temporary or definitive treatment strategy is ideal. Although indicating the correct therapeutic regimen may prove challenging, understanding the athlete-specific considerations can be essential to meeting the goals of the athlete and other stakeholders involved in the athlete's career. The purpose of this review is to comprehensively present the deliberations a treating physician must consider in managing cartilage injuries within a spectrum of athletic levels ranging from youth to professional levels, with a secondary focus on the presentation of temporizing treatment strategies and associated outcomes.

Arthroscopic Medial Meniscus Posterior Horn Direct Anchor Root Repair: Transtibial Approach With Knotless Adjustable Aperture Fixation.

The integrity of the posterior meniscus root attachment is vital for the preservation of knee joint biomechanics. Meniscus root tears treated nonoperatively or with meniscectomy lead to poor functional outcomes and progressive knee degeneration. Repair returns knee biomechanics back to the intact state and has an established record of positive mid-term to long-term results. Although transtibial pullout repair has been the gold standard, innovation is needed to overcome the limitations inherent to traditional approaches. The latest generation of transtibial pullout repair devices is adjustable, permits suture anchor placement directly into the root footprint, and has demonstrated encouraging early results in biomechanical analysis. This Technical Note describes an arthroscopic technique for medial meniscus posterior root repair that uses a knotless adjustable implant (SutureLoc; Arthrex) for aperture fixation via a transtibial approach with intratunnel soft anchor direct fixation and rip-stop suture configuration.

Management of Meniscus Pathology with Concomitant Anterior Cruciate Ligament Injury.

PURPOSE OF REVIEW: The purpose of this review is to summarize current clinical knowledge on the prevalence and types of meniscus pathology seen with concomitant anterior cruciate ligament (ACL) injury, as well as surgical techniques, clinical outcomes, and rehabilitation following operative management of these pathologies. RECENT FINDINGS: Meniscus pathology with concomitant ACL injury is relatively common, with reports of meniscus pathology identified in 21-64% of operative ACL injuries. These concomitant injuries have been associated with increased age and body mass index. Lateral meniscus pathology is more common in acute ACL injury, while medial meniscus pathology is more typical in chronic ACL deficiency. Meniscus tear patterns associated with concomitant ACL injury include meniscus root tears, lateral meniscus oblique radial tears of the posterior horn (14%), and ramp lesions of the medial meniscus (8-24%). These meniscal pathologies with concomitant ACL injury are associated with increased rotational laxity and meniscal extrusion. There is a paucity of comparative studies to determine the optimal meniscus repair technique, as well as rehabilitation protocol, depending on specific tear pattern, location, and ACL reconstruction technique. There has been a substantial increase in recent publications demonstrating the importance of meniscus repair at the time of ACL repair or reconstruction to restore knee biomechanics and reduce the risk of progressive osteoarthritic degeneration. Through these studies, there has been a growing understanding of the meniscus tear patterns commonly identified or nearly missed during ACL reconstruction. Surgical management of meniscal pathology with concomitant ACL injury implements the same principles as utilized in the setting of isolated meniscus repair alone: anatomic reduction, biologic preparation and augmentation, and circumferential compression. Advances in repair techniques have demonstrated promising clinical outcomes, and the ability to restore and preserve the meniscus in pathologies previously deemed irreparable. Further research to determine the optimal surgical technique for specific tear patterns, as well as rehabilitation protocols for meniscus pathology with concomitant ACL injury, is warranted.

High incidence of medial meniscus root/radial tears and extrusion in 253 patients with subchondral insufficiency fractures of the knee.

PURPOSE: The demographic and radiological risk factors of subchondral insufficiency fractures of the knee (SIFK) continue to be a subject of debate. The purpose of this study was to associate patient-specific factors with SIFK in a large cohort of patients. METHODS: Inclusion criteria consisted of patients with SIFK as verified on magnetic resonance imaging (MRI). All radiographs and MRIs were reviewed to assess characteristics such as meniscus tear presence and type, subchondral oedema presence and location, location of SIFK, mechanical limb alignment, osteoarthritis as assessed by Kellgren-Lawrence grade and ligamentous injury. A total of 253 patients (253 knees) were included, with 171 being female. The average body mass index (BMI) was 32.1 ± 7.0 kg/m2. RESULTS: SIFK was more common in patients with medial meniscus tears (77.1%, 195/253) rather than tears of the lateral meniscus (14.6%, 37/253) (p < 0.001). Medial meniscus root and radial tears of the posterior horn were present in 71.1% (180/253) of patients. Ninety-one percent (164/180) of medial meniscus posterior root and radial tears had an extrusion ≥3.0 mm. Eighty-one percent (119/147) of patients with SIFK on the medial femoral condyle and 86.8% (105/121) of patients with SIFK on the medial tibial plateau had a medial meniscus tear. Varus knees had a significantly increased rate of SIFK on the medial femoral condyle in comparison to valgus knees (p = 0.016). CONCLUSION: In this large cohort of patients with SIFK, there was a high association with medial meniscus root and radial tears of the posterior horn, meniscus extrusion ≥3.0 mm as well as higher age, female gender and higher BMI. Additionally, there was a particularly strong association of medial compartment SIFK with medial meniscus tears. As SIFK is frequently undiagnosed, identifying patient-specific demographic and radiological risk factors will help achieve a prompt diagnosis. LEVEL OF EVIDENCE: Level IV.

Osteochondral Allograft Transplantation for the Treatment of an Acetabular Defect: A Case Report.

CASE: A 20-year-old woman presented with a unipolar, 1.8 × 1.8-cm osteochondral defect of the left acetabulum. Osteochondral allograft transplantation was performed using a medial tibial plateau allograft resulting in excellent clinical outcomes across 4 different outcome scores and maintenance of the joint space at 4.3 years postoperatively. CONCLUSION: Although previous literature has demonstrated long-term clinical success of osteochondral allograft transplantation in knee, excellent clinical outcomes can also be obtained in the hip. Thus, osteochondral allograft transplantation may be a viable treatment option for adolescents and young adults with concomitant cartilage and subchondral bone hip defects.

Legal Services for Veterans (LSV): Protocol for evaluating the grant-based LSV initiative supporting community organizations' delivery of legal services to veterans.

BACKGROUND: 1.8 million Veterans are estimated to need legal services, such as for housing eviction prevention, discharge upgrades, and state and federal Veterans benefits. While having one's legal needs met is known to improve one's health and its social determinants, many Veterans' legal needs remain unmet. Public Law 116-315 enacted in 2021 authorizes VA to fund legal services for Veterans (LSV) by awarding grants to legal service providers including nonprofit organizations and law schools' legal assistance programs. This congressionally mandated LSV initiative will award grants to about 75 competitively selected entities providing legal services. This paper describes the protocol for evaluating the initiative. The evaluation will fulfill congressional reporting requirements, and inform continued implementation and sustainment of LSV over time. METHODS: Our protocol calls for a prospective, mixed-methods observational study with a repeated measures design, aligning to the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) and Integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) frameworks. In 2023, competitively selected legal services-providing organizations will be awarded grants to implement LSV. The primary outcome will be the number of Veterans served by LSV in the 12 months after the awarding of the grant. The evaluation has three Aims. Aim 1 will focus on measuring primary and secondary LSV implementation outcomes aligned to RE-AIM. Aim 2 will apply the mixed quantitative-qualitative Matrixed Multiple Case Study method to identify patterns in implementation barriers, enablers, and other i-PARIHS-aligned factors that relate to observed outcomes. Aim 3 involves a mixed-methods economic evaluation to understand the costs and benefits of LSV implementation. DISCUSSION: The LSV initiative is a new program that VA is implementing to help Veterans who need legal assistance. To optimize ongoing and future implementation of this program, it is important to rigorously evaluate LSV's outcomes, barriers and enablers, and costs and benefits. We have outlined the protocol for such an evaluation, which will lead to recommending strategies and resource allocation for VA's LSV implementation.

Trends in functional outcome measures in orthopedic oncology.

The purpose of this study was to identify trends in the use of functional outcome measures within orthopedic oncology. The search engine, PubMed, was reviewed for all articles over an 11-year period from 2011 to 2021 from five major journals that publish in the field of orthopedic oncology. The functional outcome measures used in the articles were recorded along with study date, study design, clinical topic/pathology, and level of evidence. Out of 5968 musculoskeletal tumor-focused articles reviewed, 293 (4.9%) included at least one outcome measure. A total of 28 different outcome tools were identified. The most popular were Musculoskeletal Tumor Society (MSTS) score (61.1%) and Toronto Extremity Salvage (TESS) score (14.0%), followed by 36-Item Short Form Survey (SF-36) (4.1%) and Patient-Reported Outcomes Measurement Information System (PROMIS) (3.8%). The use of MSTS scores decreased by 0.7% each year, whereas PROMIS increased by 1.2% each year. Seventy-four articles used more than one outcome measure. Of these 74 articles, 61 had the MSTS as one of the outcome measures. Orthopedic oncology utilizes functional outcome measures less commonly in comparison to other orthopedic subspecialties. However, this may be due in large part to orthopedic oncologists putting more emphasis on outcomes such as local recurrence, implant failure, and mortality. MSTS score is the most widely used functional outcome measure, but the utilization of PROMIS has increased recently, and could be the next step in evaluating outcomes in orthopedic oncology as it is patient-derived rather than physician-derived.

Operative Treatment of Ulnar Collateral Ligament Injury in Female Athletes.

Background: Ulnar collateral ligament (UCL) reconstruction has been the standard surgical intervention for elite male athletes with UCL insufficiency. Recently, UCL repair and augmentation with an internal brace has been increasingly performed. Purpose: To evaluate the clinical and functional outcomes as well as return-to-sport rate after UCL repair in female athletes. Study Design: Case series; Level of evidence, 4. Methods: Included were 15 female athletes (mean age, 16.5 ± 3.5 years) who underwent UCL repair between 2011 and 2021 at a single institution. Data collected included age, sport played, competition level, symptom onset, previous surgeries, mechanism of injury, surgical intervention, and return to sport. Patients were contacted via phone at minimum 24-month follow-up, and postoperative outcomes were evaluated using the Mayo Elbow Performance Score (MEPS) and the Single Assessment Numeric Evaluation (SANE). Results: Of the 15 female athletes, there were 4 cheerleaders, 3 softball players, 2 volleyball players, 2 soccer players, 1 gymnast, 1 tennis player, 1 dancer, and 1 javelin thrower. Ten of the 15 athletes (67%) competed at the high school level, 4 (26%) at the collegiate level, and 1 patient (7%) was a recreational volleyball player. In all patients, there was an acute onset of symptoms after injury. Ten patients underwent UCL repair with an internal brace (67% of athletes), while 5 underwent standard UCL repair. The median MEPS for athletes with and without an internal brace was 100 (range, 80-100). There was no significant difference of MEPS (P = .826) or SANE scores (P = .189) between the patients who received an internal brace and those who did not. Thirteen of the 15 athletes (86.7%) returned to sport. Conclusion: The UCL injuries in the female athletes in this study were the result of acute trauma. Primary UCL repair, both with and without internal bracing, was an effective surgical treatment for returning these athletes to sport.

Instagram Outperforms Twitter in Driving Social Media Engagement Among Sports Medicine Orthopaedic Surgeons.

Purpose: To determine the content posted by sports medicine orthopaedic surgeons on Instagram and Twitter and to evaluate the associated engagement. Methods: Data were collected from sports medicine orthopaedic surgeons' Instagram profiles and Twitter profiles between December 2020 and June 2022. The median number of total number of likes, comments, and retweets was calculated. The content of posts from both platforms was divided into the following categories: personal life, research, patient testimony, day in the life, pathway to becoming a physician, clinical cases, medical facts, and team coverage. Results: Data from 71 Instagram profiles and 39 Twitter profiles were used in this study. A total of 1,193 posts were identified on Instagram and 1,284 posts were identified on Twitter. The personal life category had the greatest number of posts on Instagram (303, 25.4%), whereas the medical facts category had the greatest number of posts on Twitter (251, 19.5%). Pathway to becoming a physician had the greatest median number of likes on both Instagram (97.5, range 48-2,467) and Twitter (19, range 0-50) and the greatest median number of comments on Instagram at 16 (range 1-203). The team coverage category on Instagram had the greatest percentage of likes per follower at 9.9%. A significantly greater percentage of orthopaedic surgeons posted about day in the life content, medical facts, and research on Twitter in comparison with Instagram. Instagram resulted in significantly more social media engagement than Twitter in all 8 categories (P < .05). Conclusions: Instagram resulted in significantly more social media engagement across all categories in comparison with Twitter with team coverage, personal life, and pathway to becoming a physician being the most popular categories. Clinical Relevance: The information learned in this study may help sports surgeons understand how they may best utilize social media to engage with others and enhance their clinical practice.

High Incidence of Acute Kidney Injury Following Antibiotic-Loaded Spacer Insertion for Periprosthetic Joint Infection: An Updated Review of the Literature.

BACKGROUND: The use of antibiotic-impregnated cement during 2-stage revision arthroplasty for periprosthetic joint infection poses a risk of renal complications following spacer insertion. This systematic review aimed to investigate the rate of acute kidney injury (AKI) following antibiotic-loaded spacer insertion and to identify risk factors associated with this complication. METHODS: A systematic review was performed using PubMed, Cochrane Central, and Scopus databases. All clinical studies that documented renal complications following antibiotic-loaded spacer insertion for periprosthetic knee (total knee arthroplasty [TKA]) or hip (total hip arthroplasty [THA]) infection were included. Articles that combined THA and TKA outcomes were also included and labeled "THA + TKA." Descriptive statistics were analyzed when data were available. RESULTS: There were 24 studies (9 THA, 7 TKA, 8 THA + TKA) included. The mean incidences of spacer-related AKI across THA, TKA, and THA + TKA cohorts were 4.2 (range, 0 to 10%), 14 (range, 0 to 19%), and 27% (range, 0 to 35%), respectively. The most common patient-related risk factors for AKI were underlying chronic kidney disease or high baseline creatinine, low preoperative hemoglobin, and blood transfusion requirement. Spacer-related risk factors included high antibiotic dosage (>3.6 g/cement batch) and antibiotic type. While most recovered without complication, select patients required hemodialysis for acute management (2 THA, 18 THA + TKA) and/or developed chronic kidney disease (8 TKA, 8 THA). CONCLUSION: The rate of AKI following spacer insertion was high and likely under-reported in the literature. Surgeons should be cognizant of this devastating complication and should closely monitor at-risk patients for AKI following antibiotic-loaded spacer insertion.

Suicide risk among veterans using VHA justice-involved services: a latent class analysis.

BACKGROUND: Justice-involved Veterans experience notable risk for psychosocial stressors (e.g., homelessness) and psychiatric multimorbidity, which can result in complex clinical presentations. However, research examining how such factors coalesce to impact risk for suicide remains limited. METHODS: We conducted a latent class analysis of 180,454 Veterans accessing Veterans Health Administration (VHA) justice-related services from 2005 to 2018. RESULTS: A four-model class membership solution was identified. Among these classes, risk for suicide was highest among Veterans with greater psychiatric burden, with risk most notable among those with high VA service use. Veterans seeking healthcare primarily focused on substance use disorders or with low psychiatric burden and service use had a lower risk for suicide. CONCLUSIONS: Psychiatric multimorbidity is salient as it relates to suicide among Veterans accessing VHA justice-related services. Further evaluation of existing VHA services for this population and methods of augmenting and enhancing care for justice-involved Veterans with histories of co-occurring psychiatric conditions may be beneficial in facilitating suicide prevention efforts.

Program and Faculty Reputation Are Valued Most by Applicants to Orthopaedic Sports Medicine Fellowships.

Purpose: To determine the top orthopaedic surgery sports medicine fellowship programs in the United States and the most important aspects of fellowship programs as perceived by applicants. Methods: An anonymous survey was distributed via e-mail and text message to all current/former orthopaedic surgery residents who applied to one particular orthopaedic sports medicine fellowship program during the 2017-2018 through 2021-2022 application cycles. The survey asked applicants to rank what they considered to be the top-10 orthopaedic sports medicine fellowship programs in the United States before and after completion of their application cycle, based on operative and nonoperative experience, faculty, game coverage, research, and work-life balance. Final rank was calculated by awarding 10 points for a first-place vote, 9 points for a second-place vote, etc., with total number of points used to determine final ranking for each program. Secondary outcomes included rates of applying to perceived top-10 programs, relative importance of different fellowship program aspects, and preferred type of practice. Results: Seven-hundred sixty-one surveys were distributed with 107 applicants responding (14% response rate). Applicants voted the top orthopaedic sports medicine fellowships programs to be: (1) Steadman Philippon Research Institute, (2) Rush University Medical Center, and (3) Hospital for Special Surgery, both before and following the application cycle. When ranking fellowship program aspects, faculty members and fellowship reputation were most likely to be ranked highest in importance. Conclusions: This study demonstrates that most orthopaedic sports medicine fellowship applicants highly valued program reputation and faculty members when choosing a fellowship program and that the application/interview process did not have a substantial effect on how individuals perceived the top programs. Clinical Relevance: The findings of this study are important for residents applying to orthopaedic sports medicine fellowships and may have implications on fellowship programs and future application cycles.

Incidental findings on CT scans for robot-assisted total joint arthroplasty.

INTRODUCTION: This study documented the incidence of incidental findings from preoperative computerized-tomography (CT) scans obtained for robotic-arm-assisted total joint arthroplasty (TJA) and its effect on patient management. METHODS: A retrospective review was conducted for patients who underwent robotic-arm assisted primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) from 2016 to 2020. All patients obtained preoperative CT scans which were formally read by fellowship-trained musculoskeletal radiologists. CT's were flagged with incidental findings and those requiring physician follow-up were identified as significant. RESULTS: A total of 1519 patients (mean age, 66 years ±9; 849 females) were evaluated. Seventy-three (4.81%) patients had incidental CT scan findings, and 25 (1.65%) patients had significant incidental findings. Four patients required additional imaging and two patients required intervention. CONCLUSION: This study found a 4.81% incidence of incidental findings from preoperative CT scans for robotic-arm-assisted THA and TKA. Of these findings, less than 2% required physician follow-up and less than 1% required intervention. With the increasing popularity of robotic-arm assisted total joint arthroplasty, it is important to consider the necessity of detection and management of associated incidental findings from preoperative CT scans.

Uncovering Ankylosing Spondylitis from a Diagnosis of Parsonage-Turner Syndrome: A Case Report of Bilateral Shoulder Pain and Weakness.

Introduction: Parsonage-Turner syndrome is a rare condition that is often misdiagnosed by physicians due to the overlapping symptoms with other conditions such as rotator cuff injury and cervical radiculopathy. The etiology of the Parsonage-Turner syndrome is unknown, but has been associated with an immune-mediated response to rheumatic disease, infection, surgery, and immunizations. Case Presentation: A 18-year-old female former tennis player with a history of complex regional pain syndrome (CRPS), Ehler-Danlos syndrome (EDS), and two prior right shoulder surgeries presented to the orthopaedic clinic with bilateral shoulder pain. After a third surgery on the right shoulder, the patient later developed constant burning and sharp pain around the right shoulder that radiated toward the chest. She also experienced numbness, tingling, and weakness in the right shoulder along with pain and weakness in the left shoulder. The patient was tender over the right musculocutaneous nerve and both shoulders were inflamed on ultrasound. Electromyography (EMG) and nerve conduction studies were performed, which were consistent with a bilateral subacute on chronic brachial plexopathy, suggestive of Parsonage-Turner syndrome. Rheumatology was consulted due to an extensive family history of autoimmune diseases, leading to an additional diagnosis of ankylosing spondylitis. The patient's bilateral shoulder pain slowly improved over the following year with physical therapy and prolotherapy treatments. Conclusion: The case described, herein, represents a unique patient who presents with the rare conditions of ankylosing spondylitis, CRPS, EDS, and Parsonage-Turner syndrome. EMG was critical to differentiate Parsonage-Turner syndrome from the overlapping CRPS symptoms and without this, the diagnosis of ankylosing spondylitis may have been delayed. It is imperative physicians take a thorough history, include uncommon or rare conditions as a potential diagnosis, and undergo thorough testing while evaluating a patient to avoid unnecessary treatment therapies and patient dissatisfaction.

Educational demographics of orthopaedic surgery department chairs.

Background: Becoming chair of an academic clinical department is a tremendous achievement that takes many years of experience and clinical excellence. Objective: The purpose of this study was to determine the educational demographics of current orthopaedic surgery department chairs in the United States. Methods: A complete list of orthopaedic surgery residency programs was obtained from the Accreditation Council for Graduate Medical Education (ACGME) 2019-2020 list of residency programs. Department chairs were identified through an online search. Educational data, including where the department chair went to medical school, residency, fellowship, and type of fellowship completed were obtained. Results: A total of 145 orthopaedic department chairs were identified. The most attended medical schools by department chairs were Baylor (6 of 145, 4.1%) and Northwestern (6 of 145, 4.1%). The University of Rochester was the most common orthopaedic residency attended (9 of 145, 6.2%) and Harvard was the most common orthopaedic clinical fellowship (20 of 133, 15.0%). On average, it took 17.9 years from completion of clinical training to being named department chair. Conclusion: This study provides insight into the academic credentials, length of clinical experience, and research productivity of current orthopaedic surgery department chairs. Certain training programs may be more likely to produce department chairs and, in general, an orthopaedic surgeon is more likely to become chair at an institution where he/she previously trained. Finally, research productivity is clearly an important factor in becoming chair, as most chairs have high h-indices and a consistent track record of research excellence.

Virtual Interviews for Sports Medicine Fellowship Positions Save Time and Money but Don't Replace In-Person Meetings.

Purpose: To understand the perceptions of program directors (PDs) and fellowship applicants regarding the virtual interview process for orthopaedic surgery sports medicine fellowship programs. Methods: An anonymous online survey was distributed through the American Orthopaedic Society for Sports Medicine (AOSSM) to applicants and PDs of orthopaedic surgery sports medicine fellowship programs following the 2020-2021 fellowship application cycle. Results: A total of 40 responses were received from PDs for a response rate of 47% (40 of 85) and 72 responses were received from applicants for a response rate of 27% (72 of 271). All of the surveyed PDs (40/40, 100%) agreed/strongly agreed that the applicant's interview carries significant weight in determining where an applicant is ranked on the match list. Fifty-eight percent (23 of 40) of PDs agreed/strongly agreed that virtual interviews negatively affected their personal connection with the fellowship interviewee. The presence of virtual interviews allowed 80% (57 of 71) of applicants to go on more interviews. Seventy-three percent (51 of 70) of applicants were able to save greater than $5,000 on travel expenses and 63% (25 of 40) of fellowship programs were able to save greater than $2,500 by conducting virtual interviews. Conclusions: Virtual interviews allowed fellowship programs and applicants to complete more interviews, but both PDs and applicants stated that interviewing in-person was important for applicants to meet faculty and tour the institution where they may be spending a year. In contrast, significant financial savings resulted due to the transition to virtual interviews. Finally, both PDs and applicants were in favor of having the option of interviewing virtually, suggesting that virtual interviews may continue to play a role in future application cycles. Clinical Relevance: This study may be valuable to fellowship programs that will continue to implement virtual interviews into future application cycles.

The Paradox of Patient-Reported Outcome Measures: Should We Prioritize "Feeling Better" or "Feeling Good" After Total Knee Arthroplasty?

BACKGROUND: The use of preoperative patient-reported outcome measure (PROM) thresholds for patient selection in arthroplasty care has been questioned recently. This study aimed to identify factors affecting achievement of the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) after total knee arthroplasty (TKA) and determine the overlap between the two outcomes. METHODS: We identified 1,239 primary, unilateral TKAs performed at a single institution in 2015-2019. PROMs including the Knee injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR) and 12-item Short Form Health Survey (SF-12) were collected preoperatively and 1-year postoperatively. The likelihood of attaining PASS as per attainment of MCID was assessed. A multivariable regression was used to identify predictors of MCID and PASS. RESULTS: In total, 71.3% achieved MCID and 75.5% achieved PASS for KOOS-JR. Only 7.7% achieved MCID but not PASS, whereas almost twice this number did not achieve MCID but did achieve PASS (11.9%). Poorer preoperative KOOS-JR (OR 0.925), better SF-12 physical (OR 1.025), and mental (OR 1.027) were associated with MCID attainment. In contrast, better preoperative KOOS-JR (OR 1.030) and SF-12 mental (OR 1.025) were associated with PASS attainment. Age, gender, race, ethnicity, body mass index, Charlson index, American Society of Anesthesiologists classification, and smoking status were not significant predictors. CONCLUSION: Preoperative PROMs were associated with achieving MCID and PASS after TKA, albeit some positively and some negatively. In the era of value-based care, clinicians should not only strive to help patients "feel better" but also ensure that patients "feel good" after surgery. This study does not support the use of PROMs in prioritizing access to care.

Effective Interventions for Improving Functional Movement Screen Scores Among "High-Risk" Athletes: A Systematic Review.

BACKGROUND: The Functional Movement ScreenTM (FMSTM) is a tool designed to screen a series of movements that aids in the identification of compensatory fundamental movement patterns, functional limitations, and asymmetrical movement patterns. A previous systematic review and meta-analysis has shown that athletes with an FMSTM score <13-14 are considered "high-risk" and are more likely to be injured. There are discrepancies regarding the efficacy of physical intervention programs in improving FMSTM scores. PURPOSE: The aim of this systematic review was to assess the role of physical intervention programs in increasing functional movement in "high-risk" athletes as measured by the FMSTM. STUDY DESIGN: Systematic Review. METHODS: A computerized search was performed in 2019 according to PRISMA guidelines searching Embase, Science Direct, Ovid, and PubMed. The studies were assessed for quality and risk of bias using the Modified Downs and Black checklist. Participant demographics, intervention routines, and FMSTM scores were extracted from the included studies. RESULTS: Six studies met the inclusion criteria and demonstrated a fair methodological quality. Comparisons across all studies revealed significant improvement in FMSTM scores following implementation of a variety of physical intervention programs. These programs included those that utilized functional training, foot muscle strengthening, Pilates, core stability training, and resistance movements. Despite variations in the corrective exercises performed, the number of training sessions, and the length of the intervention program, all studies demonstrated an increase in the total FMSTM score following program implementation. CONCLUSION: The included intervention programs significantly improved total FMSTM scores in "high-risk" athletes. Despite variations in the corrective exercises (interventions) performed, the number of training sessions, and the length of the program, all studies demonstrated a significant increase in the total FMSTM score following program implementation.

A Time-Driven Activity-Based Costing Analysis of Simultaneous Versus Staged Bilateral Total Hip Arthroplasty and Total Knee Arthroplasty.

BACKGROUND: Although studies have compared the claims costs of simultaneous and staged bilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA), whether a simultaneous procedure is cost-effective to the facility remains unknown. This study aimed to compare facility costs and perioperative outcomes of simultaneous vs staged bilateral THA and TKA. METHODS: We reviewed a consecutive series of 560 bilateral THA (170 staged and 220 simultaneous) and 777 bilateral TKA (163 staged and 451 simultaneous). Itemized facility costs were calculated using time-driven activity-based costing. Ninety-day outcomes were compared. Margin was standardized to unadjusted Medicare Diagnosis Related Group payments (simultaneous, $18,523; staged, $22,386). Multivariate regression was used to determine the independent association between costs/clinical outcomes and treatment strategy (staged vs simultaneous). RESULTS: Simultaneous bilateral patients had significantly lower personnel, supply, and total facility costs compared with staged patients with no difference in 90-day complications between the groups. Multivariate analyses showed that overall facility costs were $1,210 lower in simultaneous bilateral THA (P < .001) and $704 lower in TKA (P < .001). Despite lower costs, margin for the facility was lower in the simultaneous group ($6,569 vs $9,225 for THA; $6,718 vs $10,067 for TKA; P < .001). CONCLUSION: Simultaneous bilateral TKA and THA had lower facility costs than staged procedures because of savings associated with a single hospitalization. With the increased Medicare reimbursement for 2 unilateral procedures, however, margin was higher for staged procedures. In the era of value-based care, policymakers should not penalize facilities for performing cost-effective simultaneous bilateral arthroplasty in appropriately selected patients.

Lumbar spine surgery reduces postoperative opioid use in the veteran population.

Background: The United States has been facing a worsening opioid epidemic over the past two decades. The veteran population represents a large and vulnerable group with a higher burden of mental health comorbidities. The purpose of this study was to analyze the impact of lumbar spine surgery on postoperative opioid usage in the United States veteran population. Methods: A retrospective cohort study was conducted using the Veterans Affairs Informatics and Computing Infrastructure database. Patients who underwent lumbar spine surgery were stratified into three groups by their preoperative opioid claims within 365 days of surgery. Postoperative cumulative morphine milligram equivalents (MME) were tracked for each group and the paired Wilcoxon signed rank test was used to compare cumulative preoperative MME (days -365-0) to cumulative postoperative MME (days 91-455). Results: At one year, 30.6% of patients in the high preoperative opioid group and 73.1% of patients in the low preoperative opioid group were no longer using opioids. In the opioid naive cohort, 10.0% of patients were still using opioids at one year. Among all patients, median cumulative postoperative MME was significantly less than median cumulative preoperative MME (P<0.001). High preoperative opioid usage of more than 3 claims was most significantly associated with continued postoperative opioid usage (odds ratio 12.55, P<0.001). From 2010 to 2020 the proportion of patients with preoperative opioid claims decreased (58.8% to 34.8%). Conclusions: In the veteran population, lumbar spine surgery was effective in getting 50% of patients who were on opioids preoperatively to discontinue opioids postoperatively. Even minimal exposure to opioids preoperatively resulted in a 2.69-time increase in risk of being on opioids at one year versus opioid naive patients. This study affirms that despite being a high-risk population, the veteran population has a similar response to lumbar spine surgery as the general population in regards to opioid dependence.
