RESUMO
In 2021, the Centers for Medicare & Medicaid Services introduced hospital price transparency regulations, but many hospitals are still not entirely compliant, and the available data are unwieldy and opaque. The currently available data offer little insight for patients seeking to understand their actual out-of-pocket costs. Fortunately, as of January 1, 2024, the Transparency in Coverage rule mandates that insurers provide real-time cost estimator tools for out-of-pocket expenses for all medical items and services. This is crucial because price-based competition depends on patient- and insurance-specific factors, including insurance coverage (or lack thereof), access to care, and accurate estimates of out-of-pocket cost. Insurance coverage complicates hospital transparency efforts due to marked differences in billed charges and insurance payouts. If patients could input their insurance details and the service or surgery charge into a price estimator, they could receive realistic estimates across different hospitals. This could be an equitable goal. However, even if a patient can determine out-of-pocket costs, there is little actual competition when coverage only applies to hospitals within a parent network. Price transparency has the potential to substantially benefit patients, but current hospital-centric data are insufficient. Patient-centric price transparency is required; sadly, it seems that hospitals will not provide these data without tighter regulation.
RESUMO
Bacterial contamination as a result of suture contamination may be associated with rotator cuff retear or impaired tendon healing after rotator cuff repair. This represents a potential new area of focus and intervention. Despite an array of rotator cuff repair techniques, from varying suture configurations and double-row repairs to biologic adjuncts and patches, a substantial proportion of repairs do not heal or go on to retear. Decades of research have been dedicated to identifying risk factors for these failures and mitigating their influence. Yet, as we transitioned from open to arthroscopic repair, we became less concerned with regard to overt infection, which is rare using arthroscopic techniques. Now, we must take precautions to prevent occult bacterial contamination. The importance of stringent aseptic practices and tailored prophylactic measures, even in seemingly low-risk arthroscopy cases, requires attention, and similarly, with increasing numbers of shoulder injections, antisepsis around the shoulder must be practiced in all cases.
RESUMO
Recent research has investigated the impact of graft condition on the outcomes of shoulder superior capsular reconstruction for irreparable rotator cuff tears. A decreased lateral graft volume compared with the medial graft volume is more common in patients with rotator cuff arthropathy and is associated with inferior clinical outcomes. This would suggest that aside from simply failing at the suture-graft junction, grafts with thinner lateral segments may exhibit diminished biomechanical strength over time. This may explain, in part, the discrepancy in outcomes between thinned grafts and grafts with preservation of tissue thickness. However, a significant association is also shown between grafts with lateral thinning and factors that portend worse clinical outcomes, including a higher Hamada grade, larger anteroposterior distance of the graft spanning the greater tuberosity, increased fatty infiltration in the infraspinatus and subscapularis muscles, and higher rate of subscapularis retears postoperatively. This would suggest that reductions in graft volume may be a product of worse initial pathology, which in and of itself may explain the worse postoperative outcomes. Thus, it remains unclear whether the findings represent cause or effect.

BACKGROUND: There are multiple methods for calculating the minimal clinically important difference (MCID) threshold, and previous reports highlight heterogeneity and limitations of anchor-based and distribution-based analyses. The Warfighter Readiness Survey assesses the perception of a military population's fitness to deploy and may be used as a functional index in anchor-based MCID calculations. The purpose of the current study in a physically demanding population undergoing shoulder surgery was to compare the yields of 2 different anchor-based methods of calculating MCID for a battery of PROMs, a standard receiver operating characteristic (ROC) curve-based MCIDs and baseline-adjusted ROC curve MCIDs. METHODS: All service members enrolled prospectively in a multicenter database with prior shoulder surgery that completed pre- and postoperative PROMs at a minimum of 12 months were included. The PROM battery included Single Assessment Numeric Evaluation (SANE), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), Patient Reported Outcome Management Information System (PROMIS) physical function (PF), PROMIS pain interference (PI), and the Warfighter Readiness Survey. Standard anchor-based and baseline-adjusted ROC curve MCIDs were employed to determine if the calculated MCIDs were both statistically and theoretically valid (95% confidence interval [CI] either completely negative or positive). RESULTS: A total of 117 patients (136 operations) were identified, comprising 83% males with a mean age of 35.7 ± 10.4 years and 47% arthroscopic labral repair/capsulorrhaphy. Using the standard, anchor-based ROC curve MCID calculation, the area under the curve (AUC) for SANE, ASES, PROMIS PF, and PROMIS PI were greater than 0.5 (statistically valid). For ASES, PROMIS PF, and PROMIS PI, the calculated MCID 95% CI all crossed 0 (theoretically invalid). Using the baseline-adjusted ROC curve MCID calculation, the MCID estimates for SANE, ASES, and PROMIS PI were both statistically and theoretically valid if the baseline score was less than 70.5, 69, and 65.7. CONCLUSION: When MCIDs were calculated and anchored to the results of standard, anchor-based MCID, a standard ROC curve analysis did not yield statistically or theoretically valid results across a battery of PROMs commonly used to assess outcomes after shoulder surgery in the active duty military population. Conversely, a baseline-adjusted ROC curve method was more effective at discerning changes across a battery of PROMs among the same cohort.
RESUMO
BACKGROUND: The Goutallier classification (GC) is used to assess fatty atrophy in rotator cuff (RC) tears, yet limitations exist. A battery of 3-dimensional (3D) magnetic resonance imaging (MRI) volumetric scores (VSs) was developed to provide comprehensive characterization of RC pathology. The purposes of this study were to (1) describe the correlation between GC and VSs for supraspinatus changes in RC tears, (2) characterize the chronicity of RC tears using a battery of 12 VS measurements, and (3) compare GC and VSs to determine which method most closely corresponds with preoperative patient-reported outcome measures (PROMs). METHODS: Preoperative shoulder MRIs were reviewed after arthroscopic RC repair. Preoperative GC stage and Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) and pain interference (PI) scores were collected. The battery of VSs included fat infiltration (FIS), muscle size (MSS), and relative volume contribution (RCS) for each RC muscle. Backward linear regression was performed to compare GC stage with preoperative PROMIS PF and PI to determine which VS measurement most closely correlated with preoperative PROMs. RESULTS: Eighty-two patients underwent RC repair (mean age 55 ± 8.2 years, 63% male, 68% GC stage ≤1). In evaluation of the supraspinatus, there was a moderate positive correlation between GC and FIS (r = 0.459, P < .001); strong negative correlations were observed between MSS (r = -0.800, P < .001) and RCS (r = -0.745, P < .001) when compared to GC. A negligible linear correlation was observed between GC and preoperative PROMIS PF (r = -0.106, P = .343) and PI (r = -0.071, P = .528). On multivariate analysis, subscapularis MSS (ß >0, P = .064) was a positive predictor and subscapularis FIS (ß <0, P = .137), teres minor MSS (ß <0, P = .141), and FIS (ß <0, P = .070) were negative predictors of preoperative PF (r = 0.343, P = .044); in contrast, supraspinatus MSS (ß >0, P = .009) and FIS (ß >0, P = .073), teres minor FIS (ß >0, P = .072), and subscapularis FIS (ß >0, P = .065) were positive predictors of preoperative PI (r = 0.410, P = .006). CONCLUSION: Although the criterion standard in evaluation of RC pathology, GC demonstrated negligible correlation with preoperative functional disability. Alternatively, a battery of 3D VSs showed strong correlation with GC through a quantitative, comprehensive evaluation of the RC unit including several moderate predictors of preoperative functional disability.
RESUMO
OBJECTIVE: Tibial tubercle fractures are a unique class of pediatric orthopaedic injuries that frequently necessitate surgical treatment and strict monitoring due to the associated risk of acute compartment syndrome (ACS). However, current literature is conspicuously limited in its ability to estimate the risk of ACS after these fractures. Therefore, the purpose of this study is to utilize a nationwide database to estimate the prevalence of ACS after pediatric tibial tubercle fractures. METHODS: We utilized the Healthcare Cost and Utilization Project's Kids' Inpatient Database (2019) to identify all pediatric patients, 18 years of age and under, with isolated tibial tubercle fractures (International Classification of Diseases, 10th revision Clinical Modification S82.151-S82.156) and ACS (T79.A0, T79.A2, T79.A29). Patients were excluded if they had additional lower extremity injuries (ie, tibial shaft, plateau, etc). A subanalysis was conducted for those undergoing fasciotomy, with and without an ACS diagnosis. RESULTS: Among the 591 isolated tibial tubercle fractures, there were 8 ACS cases for a prevalence of 1.35%. There were 22 (3.72%) additional cases of fasciotomy without an ACS diagnosis. All ACS cases were diagnosed during the original hospitalization; all were male and had closed fractures. The cohort included 469 teenagers (13+ years) and 77 pre-teens, with 40 females and 506 males. Racial demographics: 132 white, 232 black, 112 Hispanic, 15 Asian, 4 Native American, 23 unknown, and 28 others. No significant associations were found between ACS and age, race, insurance status, mechanism of injury, or hospital region. CONCLUSION: The rate of ACS in pediatric tibial tubercle fractures appears to be much lower than previously reported, at 1.35%. However, the nearly three-fold higher prevalence of fasciotomy without an ACS diagnosis, suggests a generous use of prophylactic fasciotomies and/or an undercharacterization of actual ACS cases from miscoding. This is the first and largest study to employ a nationally representative database to investigate the prevalence of ACS after tibial tubercle fractures. LEVEL OF EVIDENCE: Level III.
RESUMO
BACKGROUND: Multiple surgical treatments exist for proximal humerus fractures (PHFs), but current practice patterns and short-term complication profiles remain poorly understood. This is in part due to changes in treatment paradigms over the past decade. A more thorough understanding of the evolution in management over this time as well as an appreciation of the preoperative factors associated with both the chosen surgical modality and short-term complications will help inform future surgical considerations. QUESTIONS/PURPOSES: In this study, we sought to: (1) characterize trends in the surgical management of PHFs over time, including usage rates of various surgical modalities and changes in complication rates; (2) identify preoperative variables associated with the selection of surgical modality; and (3) assess the independent covariates of acute 30-day complications, including demographic variables, injury characteristics, and treatment type. METHODS: The National Surgical Quality Improvement Program (NSQIP) database was queried using Current Procedural Terminology and ICD-9 and ICD-10 codes to identify individuals with PHF undergoing open reduction and internal fixation (ORIF), hemiarthroplasty (HA), or reverse total shoulder arthroplasty (RTSA) from 2007 to 2018. The NSQIP database was utilized because of its collection of detailed preoperative demographic information and large repository of clinically derived data, which is felt to be more accurate than claims or administrative data. In total, 5889 patients with PHFs met the inclusion criteria. Patients 17 years or older were included. Patients with isolated greater tuberosity, humeral shaft, and distal humerus fractures; nonunions; malunions; and those undergoing revision procedures were excluded. A Cochran-Armitage test was used to evaluate surgical trends over time. Multivariable logistic regression models were created to identify covariates associated with surgical modality and complications. Although complications were either classified as major or minor, specific complications were also individually analyzed to avoid potentially misleading conclusions associated with pooling. RESULTS: The proportion of patients with PHFs undergoing RTSA (4% in 2007 and 34% in 2018; p < 0.001) and ORIF (46% in 2007 and 57% in 2018; p < 0.001) increased over time, and the proportion of those undergoing HA (50% in 2007 and 9% in 2018; p < 0.001) decreased. Across each surgical modality, minor complication rates decreased over time (RTSA: 10% in 2018; p < 0.001; ORIF: 5% in 2018; p = 0.01; and HA: 6% in 2018; p = 0.01). After controlling for confounding variables like diabetes, chronic obstructive pulmonary disease, congestive heart failure, dialysis, and preoperative blood transfusion, the following factors were independently associated with an increased odds of a patient undergoing RTSA rather than HA: older age, higher BMI, independent functional status, and smoking. The following factors were independently associated with a decreased odds of a patient undergoing ORIF rather than RTSA and HA: older age, higher BMI, higher American Society of Anesthesiologists (ASA) classification, smoking, steroid/immunosuppressant use, as well as three- and four-part fractures. After controlling for age, ASA classification, functional status, and preoperative blood transfusion, we also found that in the latter part of the study period, arthroplasty (RTSA and HA) was no longer independently associated with 30-day major or minor complications compared with ORIF. CONCLUSION: The increasing utilization of RTSA and decreasing short-term complication rates for fixation and arthroplasty alike represent a substantial change compared even with recent historic norms in the management of proximal humerus fractures. Quantifying demographics, injury characteristics, and comorbidities associated with both the choice of surgical modality and complications serves as the groundwork for decision support tools, which can inform patients and surgeons of the probability of a particular surgical modality being chosen and the risk of complications, based on national benchmarks. Future studies should investigate longer term complication rates, as many differences between the approaches being compared might occur beyond the perioperative period and our study had no means to address questions about complications beyond that period, but obviously those must be considered when choosing a treatment for patients with these injuries. Future work might also investigate the mechanisms behind the decreasing rates of short-term complications. LEVEL OF EVIDENCE: Level III, therapeutic study.

PURPOSE: To determine whether posterior glenoid bone block augmentation performed for the treatment of recurrent posterior shoulder instability succeeds in restoring stability and is associated with rates of complications or clinical failures comparable to other glenoid bone augmentation procedures. METHODS: A comprehensive search of PubMed, MEDLINE, and EMBASE databases was performed. Level of evidence studies I to IV pertaining to posterior bone block augmentation reporting on outcomes or complications were included. The search was carried out in accordance with the Preferred Reported Items for Systematic Reviews and Meta-analyses guidelines. RESULTS: Screening of titles, abstracts, and manuscripts with application of inclusion and exclusion criteria yielded 17 full-text articles reporting on 269 shoulders undergoing bone block augmentation. Surgical technique varied between studies with regard to graft type (iliac crest, 13 studies; scapular spine, 2; acromion, 1; distal tibia allograft, 1), graft positioning (medial to 1.5 cm lateral to glenoid surface, equatorial to subequatorial), and open versus arthroscopic technique (open, 10 studies; arthroscopic, 4; both, 3). Four of the 8 studies with pre- and postoperative patient-reported outcomes (PROs) showed significant improvements in these outcomes at final follow-up. The postoperative outcomes ranged from 60 to 90 for Rowe scores (n = 7 studies) and 79 to 90 for Walch-Duplay scores (n = 7 studies). Complications were commonly encountered, with high rates of recurrent instability (0% to 73%) and revision procedures (0% to 67%) across different studies. CONCLUSION: Posterior bone block augmentation for recurrent posterior shoulder instability does not reliably yield substantial improvements in PROs, and complications are frequently observed. The substantial heterogeneity across studies and the small number of patients precludes any substantive judgements as to the superiority of one surgical technique over another. LEVEL OF EVIDENCE: IV, systematic review of level III and IV studies.

The pros and cons of open and arthroscopic shoulder stabilization procedures have been studied exhaustively. Yet, in many situations, the rates of recurrent instability and overall complications associated with these techniques remain unacceptably high. Perhaps paradoxically, the refinement of arthroscopic shoulder stabilization techniques has only intensified the debate between proponents of either open or arthroscopic approaches, and although significant (however "significant" is defined), anteroinferior glenoid bone loss has historically been thought to constitute a relatively strong indication for an open bone augmentation procedure, surgeons, to their great credit, continue to push the limits of what can be accomplished arthroscopically. Arthroscopic glenoid reconstruction has emerged as a viable option that may represent "the best of both worlds." Although modifications to the originally described arthroscopic glenoid reconstruction technique are promising, concerns persist regarding the fate of the graft and the durability of the procedure beyond short-term follow-up.

PURPOSE: To determine if an increased critical shoulder angle (CSA) predisposes patients to higher re-tear rates and worse clinical outcomes after rotator cuff (RC) repair. METHODS: A comprehensive search of the PubMed, MEDLINE, and EMBASE databases was performed in October 2018 for English-language studies pertaining to RC repair and an increased CSA in accordance with Preferred Reported Items for Systematic Reviews and Meta-analyses guidelines. Studies of all levels of evidence were included provided that any outcomes, including pain, patient-reported outcomes, and re-tear rates, were reported. RESULTS: Of a group of 1126 studies that satisfied the initial search criteria, 6 studies were included in the final analysis, comprising data from 473 patients. Three comparative studies were assessed for an association between increased CSA and RC re-tear rates. Among these 3 studies that compared RC re-tear rate in patients with larger and smaller CSAs, 22 of 97 patients (23%) with a larger CSA had a RC re-tear in comparison to 10 of 99 patients (10%) with a smaller CSA. All 3 studies demonstrated higher RC re-tear rates in patients with larger CSAs (risk ratio, 2.39-9.66, I2 = 7%.) The mean CSA in those patients who did not have RC re-tears ranged from 34.3° to 37°, and the mean CSA in those patients who had RC re-tears ranged from 37° to 40°. CONCLUSION: RC re-tear rates were higher in patients with larger CSAs among comparative, nonrandomized studies. However, the heterogeneity of the relevant literature limits the strength of his observation. Based on the current literature, it remains unclear as to whether lateral acromioplasty affects clinical outcomes as a function of a reduced postoperative CSA. LEVEL OF EVIDENCE: Level IV, systematic review of Level II to IV studies.

OBJECTIVE Postoperative complications are one of the most significant concerns in surgeries of the spine, especially in higher-risk cases such as neuromuscular scoliosis. Neuromuscular scoliosis is a classification of multiple diseases affecting the neuromotor system or musculature of patients leading to severe degrees of spinal deformation, disability, and comorbidity, all likely contributing to higher rates of postoperative complications. The objective of this study was to evaluate deformity correction of patients with neuromuscular scoliosis over a 12-year period (2004-2015) by looking at changes in postsurgical complications and management. METHODS The authors queried the Scoliosis Research Society (SRS) Morbidity and Mortality (M&M) database for neuromuscular scoliosis cases from 2004 to 2015. The SRS M&M database is an international database with thousands of self-reported cases by fellowship-trained surgeons. The database has previously been validated, but reorganization in 2008 created less-robust data sets from 2008 to 2011. Consequently, the majority of analysis in this report was performed using cohorts that bookend the 12-year period (2004-2007 and 2012-2015). Of the 312 individual fields recorded per patient, demographic analysis was completed for age, sex, diagnosis, and preoperative curvature. Analysis of complications included infection, bleeding, mortality, respiratory, neurological deficit, and management practices. RESULTS From 2004 to 2015, a total of 29,019 cases of neuromuscular scoliosis were reported with 1385 complications, equating to a 6.3% complication rate when excluding the less-robust data from 2008 to 2011. This study shows a 3.5-fold decrease in overall complication rates from 2004 to 2015. A closer look at complications shows a significant decrease in wound infections (superficial and deep), respiratory complications, and implant-associated complications. The overall complication rate decreased by approximately 10% from 2004-2007 to 2012-2015. CONCLUSIONS This study demonstrates a substantial decrease in complication rates from 2004 to 2015 for patients with neuromuscular scoliosis undergoing spine surgery. Decreases in specific complications, such as surgical site infection, allow us to gauge our progress while observing how trends in management affect outcomes. Further study is needed to validate this report, but these results are encouraging, helping to reinforce efforts toward continual improvement in patient care.

Purpose: To evaluate the peer-reviewed orthopaedic sports medicine literature for reference errors within 2 high-impact journals. Methods: In total, 769 references with 1,082 in-line citations were assessed from 20 randomly selected peer-reviewed articles published in 2 high-impact orthopaedic sports medicine journals, Arthroscopy and the American Journal of Sports Medicine. Full-text copies of references were obtained through online literature subscription databases. Two investigators evaluated each citation for agreement between the reference's study design, methods, data, discussion, and conclusion with the citing authors' claims. Error rates, interobserver agreement, and association between error rates and journal demographics were assessed. Results: Cohen's κ coefficient representing interobserver agreement was 0.61. The mean citation error rate across 20 articles from 2 orthopaedic sports medicine journals was 6.6%. The most common error was failure to support the authors' assertions within the citing article, accounting for 32% of errors. There was no significant association between error rate and journal impact factor, number of cited references or total references, ratio of in-line citations to cited references (citation ratio), and number of authors. There was no significant relationship between error rate and journal, study type, and level of evidence. Conclusions: Inaccurate claims and citations are common within the orthopaedic sports medicine literature, occurring in every reviewed article and 6.6% of all in-line citations. Failure to support the assertions of the article in which a reference is cited is a common error. Authors should take care to rigorously assess references with particular attention to accurate citation of primary sources. Clinical Relevance: This study highlights the prevalence of citation errors within a random sampling of high-level orthopaedic sports medicine articles. Given science is cumulative, these errors perpetuate inaccuracies and are at odds with evidence-based practice.
RESUMO
INTRODUCTION: As the utilization of minimally invasive sacroiliac joint fusion (SIJF) continues to expand, a better understanding of postoperative outcomes is needed, particularly in young and active individuals. The purpose of this study is to assess the outcomes of this procedure in an active duty military population by examining return-to-duty (RTD) rates. MATERIALS AND METHODS: A retrospective review of the electronic medical record from a tertiary military medical center was performed for active duty service members undergoing SIJF from January 2013 to January 2019. The primary outcome measured was RTD at 6 months, with active duty status at 1 year, last follow-up, and revision surgery as secondary outcomes. Demographic and surgical variables recorded included patient age, gender, military rank, utilization of navigation, and implant type. RESULTS: Sixteen service members met the inclusion criteria, with a mean age of 40.5 ± 6.7 years. The mean follow-up after surgery was 24 ± 15 months. Patients received either cylindrical (n = 6) or triangular (n = 10) implants placed with (n = 6) or without (n = 10) navigation. Within 6 months of surgery, 56% of patients were able to RTD. Patients undergoing navigation-assisted procedures were significantly more likely to RTD at 6 months (100% vs. 30%, P = .011) compared to those undergoing surgery performed with orthogonal fluoroscopic imaging. Compared to those with cylindrical implants, patients with triangular implants were also more likely to RTD at 6 months (80% vs. 17%, P = .035). CONCLUSIONS: Following SIJF, a small majority of service members were able to return to full active duty status by 6 months. Further studies are needed to assess the potential benefits of navigation and implant selection, as our retrospective review noted differences in outcomes based on these variables.

Background and Objective: Anterior shoulder instability can be debilitating for young, active individuals, and increasing magnitudes of glenoid bone loss (GBL) predisposes patients to recurrent instability and increases the likelihood of failure of soft-tissue only repairs. It is widely accepted that GBL >25% should be treated with a glenoid bone grafting procedure. However, consensus is lacking on the optimal management in the setting of subcritical GBL, typically classified as >13.5%. This article reviews the pathoanatomy relevant to anterior shoulder instability and subcritical GBL, while highlighting existing evidence regarding open augmentation procedures in comparison to other treatment options for this subpopulation. Methods: A narrative review of the current literature was conducted focusing on subcritical GBL in anterior glenoid stabilization procedures, including review of forward citation and reference lists of selected articles. Key Content and Findings: Computed tomography (CT) is the modality of choice for obtaining precise measurements of subcritical GBL, defined as <13.5%, using the best-fit circle method. There is debate surrounding the optimal surgical management of subcritical GBL. Arthroscopic Bankart repair (ABR) remains the predominate surgery performed for primary anterior shoulder instability, while glenoid augmentation and open Bankart repair continue to be used sparingly in the United States. Historically, the Latarjet procedure was considered for substantial glenoid defects, but the illumination of subcritical GBL has expanded its indications. Arthroscopic, soft tissue-only repairs with the addition of remplissage, has been shown to have similar 2-year outcomes to the Latarjet in patients with >15% GBL, which has been limited in the study of subcritical GBL. Additionally, utilization of distal tibial allograft and local autograft is becoming increasingly prevalent. However, again, with limited prospective studies in the subcritical GBL population. Conclusions: There is no consensus regarding the optimal treatment approach to recurrent shoulder instability in the setting of subcritical GBL. Conversely, there is a growing agreement that isolated ABR is likely inadequate and subcritical GBL should prompt consideration of a more robust operation. To this end, interest in glenoid bone augmentation continues to grow as a reliable technique for recreating the native architecture and restoring glenohumeral stability are developed.
RESUMO
Poor functional outcomes after hemiarthroplasty for proximal humerus fractures are common, yet revision surgery is relatively rare. Arthroscopic treatment for postoperative stiffness can be considered in the setting of functional limits to glenohumeral range of motion impacting activities of daily living after adequate conservative treatment with physical therapy and in the setting of healed, well-positioned tuberosities and humeral components. This Technical Note illustrates a stepwise approach to an arthroscopic lysis of adhesions and capsular release for the treatment of arthrofibrosis of the shoulder. The advantages of this technique include an alternative approach to entering the glenohumeral joint under direct subacromial visualization and a 2-posterior portal approach to the inferior and anteroinferior capsule, which can be challenging to achieve in the setting of severe postsurgical arthrofibrosis.
RESUMO
Tendon injuries in military servicemembers are one of the most commonly treated nonbattle musculoskeletal injuries (NBMSKIs). Commonly the result of demanding physical training, repetitive loading, and frequent exposures to austere conditions, tendon injuries represent a conspicuous threat to operational readiness. Tendon healing involves a complex sequence between stages of inflammation, proliferation, and remodeling cycles, but the regenerated tissue can be biomechanically inferior to the native tendon. Chemical and mechanical signaling pathways aid tendon healing by employing growth factors, cytokines, and inflammatory responses. Exosome-based therapy, particularly using adipose-derived stem cells (ASCs), offers a prominent cell-free treatment, promoting tendon repair and altering mRNA expression. However, each of these approaches is not without limitations. Future advances in tendon tissue engineering involving magnetic stimulation and gene therapy offer non-invasive, targeted approaches for improved tissue engineering. Ongoing research aims to translate these therapies into effective clinical solutions capable of maximizing operational readiness and warfighter lethality.
RESUMO
The unique physical demands of tactical athletes put immense stress on the knee joint, making these individuals susceptible to injury. In order to ensure operational readiness, management options must restore and preserve the native architecture and minimize downtime, while optimizing functionality. Osteochondral lesions (OCL) of the knee have long been acknowledged as significant sources of knee pain and functional deficits. The management of OCL is predicated on certain injury characteristics, including lesion location and the extent of subchondral disease. Techniques such as marrow stimulation, allograft and autologous chondrocyte implantation are examined in detail, with a focus on their application and suitability in tactical athlete populations. Moreover, the restoration of the osteochondral unit (OCU) is highlighted as a central aspect of knee joint preservation. The discussion encompasses the biomechanical considerations and outcomes associated with various cartilage restoration techniques. Factors influencing procedure selection, including lesion size, location, and patient-specific variables, are thoroughly examined. Additionally, the review underscores the critical role of post-operative rehabilitation and conditioning programs in optimizing outcomes. Strengthening the surrounding musculature, enhancing joint stability, and refining movement patterns are paramount in facilitating the successful integration of preservation procedures. This narrative review aims to provide a comprehensive resource for surgeons, engineers, and sports medicine practitioners engaged in the care of tactical athletes and the field of cartilage restoration. The integration of advanced preservation techniques and tailored rehabilitation protocols offers a promising avenue for sustaining knee joint health and function in this demanding population.
RESUMO
INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) is typically used to provide mechanical perfusion and gas exchange to critically ill patients with cardiopulmonary failure. We present a case of a traumatic high transradial amputation in which the amputated limb was placed on ECMO to allow for limb perfusion during bony fixation and preparations and coordination of orthopedic and vascular soft tissue reconstructions. MATERIALS AND METHODS: This is a descriptive single case report which underwent managment at a level 1 trauma center. Instutional review board (IRB) approval was obtained. RESULTS: This case highlights many important factors of limb salvage. First, complex limb salvage requires a well-organized, pre-planned multi-disciplinary approach to optimize patient outcomes. Second, advancements in trauma resuscitation and reconstructive techniques over the past 20 years have drastically expanded the ability of treating surgeons to preserve limbs that would have otherwise been indicated for amputation. Lastly, which will be the focus of further discussion, ECMO and EP have a role in the limb salvage algorithm to extend current timing limitations for ischemia, allow for multidisciplinary planning, and prevent reperfusion injury with increasing literature to support its use. CONCLUSIONS: ECMO is an emerging technology that may have clinical utility for traumatic amputations, limb salvage, and free flap cases. In particular, it may extend current limitations of ischemia time and reduce the incidence of ischemia reperfusion injury in proximal amputation, thus expanding the current indications for proximal limb replantation. It is clear that developing a multi-disciplinary limb salvage team with standardized treatment protocols is paramount to optimize patient outcomes and allows limb salvage to be pursued in increasingly complex cases.
