RESUMO
Background: In the continually aging United States population, the number of patients with sarcopenia who undergo shoulder arthroplasty may concomitantly increase. This retrospective cohort study aims to evaluate the rates of short-term implant-related and medical complications following shoulder arthroplasty in patients with and without a recent diagnosis of sarcopenia. Methods: An exact 1:3 matched analysis of 4177 patients was performed using the PearlDiver database. Multivariable logistic regression was used to compare complications, Kaplan-Meier failure analysis was used to compare the cumulative hospital readmission rates. Two-sample T-testing was used to compare the 90-day cost of care. Results: Sarcopenic patients were significantly more likely to experience postoperative shoulder instability (odds ratio (OR) = 2.32, 95% confidence interval (CI), 1.21-4.39) and periprosthetic infection (OR = 3.83, 95% CI, 1.74-8.67) within 1 year of their arthroplasty. Sarcopenic patients were at 25% and 41% greater risk of emergency department presentation and hospital readmission 1-year post-arthroplasty, respectively. Ninty-day total costs were greater among sarcopenics ($16 112.23 vs. 10 679.58, p < 0.001). Conclusion: These results are important for orthopaedic surgeons counselling patients with a low muscle mass on the potential for increased complications after undergoing a total shoulder arthroplasty procedure.
RESUMO
BACKGROUND: Coracoid nonunion is a relevant complication following the Latarjet procedure and is influenced by multiple factors, including the method of graft fixation. The purpose of this study was to evaluate and characterize the biomechanical properties of various two-screw fixation constructs used for coracoid graft fixation in the Latarjet procedure. METHODS: Forty model scapulae (Sawbones Inc., Vashon, WA, USA) were used for this study. A 15% anterior inferior glenoid bone defect was created. The coracoid was osteotomized at the juncture of the vertical and horizontal aspects, transferred to the anterior-inferior edge of the glenoid, and fixed with either two 3.5 mm fully threaded cannulated cortical screws, two 3.5 mm fully threaded solid cortical screws, two 3.5 mm partially threaded cannulated screws, or two 4.5 mm partially threaded malleolar screws (MS). Biomechanical testing was performed with an Instron material testing machine (Instron Corp., Norwood, MA, USA) by applying loads to the lateral aspect of the transferred coracoid graft. The constructs were preconditioned with nondestructive cyclical loading (0N-20N) to determine construct stiffness. After 100 cycles of dynamic loading, the construct was loaded to failure to determine ultimate failure load, yield displacement, and mode of failure. RESULTS: All failures were associated with plastic deformation of the screws and coracoid graft fracture. There was a significantly lower initial stiffness for partially threaded cannulated screws compared to MS (186 ± 49.3 N/mm vs. 280 ± 65.5 N/mm, P = .01) but no significant differences among the other constructs. There was no difference in ultimate failure load (P = .18) or yield displacement (P = .05) among constructs. CONCLUSION: Two screw coracoid fixation of the coracoid in a simulated classic Latarjet procedure with 3.5 mm fully threaded cortical and cannulated screws is comparable to 4.5 mm MS in strength, stiffness, and displacement at failure. On the other hand, partially threaded 3.5 mm cannulated screws provide inferior fixation stiffness and could potentially affect clinical outcomes.
RESUMO
PURPOSE: Anabolic steroid therapy has been associated with tendon injury, but there is a paucity of evidence associating physiologic testosterone replacement therapy (TRT) with tenosynovitis of the hand, specifically trigger finger and de Quervain tenosynovitis. The purpose of this study was to evaluate the relationship between TRT and tenosynovitis of the hand. METHODS: This was a one-to-one exact matched retrospective cohort study using a large nationwide claims database. Records were queried between 2010 and 2019 for adult patients who filled a prescription for TRT for 3 consecutive months. Rates of new onset trigger finger and de Quervain tenosynovitis and subsequent steroid injection or surgery were identified using ICD-9, ICD-10, and Current Procedural Terminology billing codes. Single-variable chi-square analyses and multivariable logistic regression were used to compare rates in the TRT and control cohorts while controlling for potential confounding variables. Both unadjusted and adjusted odds ratios (OR) are reported for each comparison. RESULTS: In the adjusted analysis, patients undergoing TRT were more than twice as likely to develop trigger finger compared to their matched controls. TRT was also associated with an increased likelihood of experiencing de Quervain tenosynovitis. Of the patients diagnosed with either trigger finger or de Quervain tenosynovitis over the 2-year period, patients with prior TRT were roughly twice as likely to undergo steroid injections or surgical release for both trigger finger and de Quervain tenosynovitis compared to the controls. CONCLUSIONS: TRT is associated with an increased likelihood of both trigger finger and de Quervain tenosynovitis, and an increased likelihood of requiring surgical release for both conditions. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Introduction: Intraosseous ganglion cysts are an uncommon variant found in the subchondral bone. We report here the development of an intraosseous ganglion cyst of the proximal tibia in the setting of a prior left total knee arthroplasty (TKA) with an all-polyethylene tibial component. Case Report: The cyst was diagnosed on routine follow-up radiographs approximately 4 years status post-TKA. Although initially asymptomatic, 1 year later the patient presented with progressive knee pain and ambulation limitations, so revision TKA was indicated. Computed tomography confirmed an osteolytic lesion suggestive of a penetrating ganglion. Given the absence of malrotation or malalignment of the well-fixed femoral component, the decision was made to proceed with tibial revision to stemmed component cemented through a porous tantalum cone. Postoperatively, the patient had complete resolution of pain and instability with 0-120° of stable range of motion, which has persisted to the latest follow-up at over 6 months post-operative, with radiographic resolution of the cyst. Conclusion: This case demonstrates a ganglion cyst surrounding total knee implants as a possible source of persistent pain following TKA. To our knowledge, this is the first report of such a case. This case demonstrates that refractory painful knee implants secondary to tibial ganglion cysts can be treated successfully with revision arthroplasty.
RESUMO
BACKGROUND: The use of a distal tibial allograft (DTA) for reconstruction of a glenoid defect in anterior shoulder instability has grown significantly over the past decade. However, few large-scale clinical studies have investigated the clinical and radiographic outcomes of the DTA procedure. PURPOSE: To conduct a systematic review and meta-analysis of clinical studies with data on outcomes and complications in patients who underwent the DTA procedure for recurrent anterior shoulder instability with glenoid bone loss. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 4. METHODS: A comprehensive search of major bibliographic databases was conducted for articles pertaining to the use of a DTA for the management of anterior shoulder instability with associated glenoid bone loss. Postoperative complications and outcomes were extracted and compiled in a meta-analysis. RESULTS: Of the 8 included studies with 329 total participants, the mean patient age was 28.1 ± 10.8 years, 192 (83.8%) patients were male, and the mean follow-up was 38.4 ± 20.5 months. The overall complication rate was 7.1%, with hardware complications (3.8%) being the most common. Partial graft resorption was observed in 36.5% of the participants. Recurrent subluxation was reported in 1.2% of the participants, and recurrent dislocation prompting a reoperation was noted in 0.3% of the participants. There were significant improvements in clinical outcomes, including American Shoulder and Elbow Surgeons score (40.9-point increase; P < .01), Single Assessment Numeric Evaluation (47.2-point increase; P < .01), Western Ontario Shoulder Instability Index (49.4-point decrease; P < .01), Disabilities of the Arm, Shoulder and Hand (20.0-point decrease; P = .03), and visual analog scale (2.1-point decrease; P = .05). Additionally, postoperative shoulder range of motion significantly increased from baseline values. CONCLUSION: The DTA procedure was associated with a low complication rate, good clinical outcomes, and improved range of motion among patients with anterior shoulder instability and associated glenoid defects.
RESUMO
BACKGROUND: The relationship between psoriasis and complications after primary TKA is not well defined. Current studies are limited to small, single-center studies evaluating fewer than 150 patients with psoriasis, with some studies reporting an increased risk of surgical site infection (SSI) and another reporting no associated risk. There is a need to reevaluate the risk of psoriasis and postoperative complications, including SSI, to better risk-stratify and guide practice in this patient population. QUESTIONS/PURPOSES: (1) Compared with patients without psoriasis, after accounting for potential confounders such as age, insurance, and comorbidities, do patients with psoriasis have a higher odds of superficial SSI after primary TKA? (2) Do patients with psoriasis have a higher odds of deep SSI after primary TKA? METHODS: Patients 18 years or older who underwent unilateral, primary TKA between 2015 and 2019 were identified in the PearlDiver database (n = 490,722). Patients with rheumatoid, septic, or posttraumatic arthritis were excluded, as well as patients with bone neoplasias (n = 188,557). Additionally, patients with less than 2 years of follow-up (n = 53,673) were excluded. In all, 248,492 patients were included in this study; 0.4% (1078) were in the psoriasis group and 99% (247,414) were in the control group. Overall 2-year superficial and deep SSI rates were stratified and compared between patients with psoriasis and a control group of patients who did not have psoriasis as the primary outcome. Secondary outcomes included the odds of undergoing an aseptic revision or manipulation under anesthesia. RESULTS: In the multivariable analysis, which controlled for potential confounders such as age, sex, Elixhauser comorbidity index, hypertension, diabetes mellitus, and liver disease, the odds of SSI-either superficial or deep-remained higher for patients with psoriasis (OR 1.74 [95% confidence interval 1.03 to 2.96]; p = 0.04). When focusing on superficial infections in the multivariable analysis, patients with psoriasis had a higher odds of superficial SSI than those in the control group (OR 2.83 [95% CI 1.26 to 6.34]; p = 0.01). The odds of deep SSI were not different between the two cohorts in our multivariable analysis (OR 1.32 [95% CI 0.66 to 2.66]; p = 0.43). Patients with psoriasis did not have an increased odds of undergoing an aseptic revision (OR 0.79 [95% CI 0.48 to 1.32]; p = 0.38) or manipulation under anesthesia (OR 0.74 [95% CI 0.52 to 1.06]; p = 0.10). CONCLUSION: Patients with psoriasis had higher overall rates of SSI at 2 years of follow-up than patients without psoriasis. Our findings suggest that psoriasis is a risk factor for superficial SSI after primary TKA and is an important comorbidity for surgeons to consider before surgery. Further research is needed to assess the role of adjunctive interventions in patients with psoriasis to mitigate the elevated odds of superficial SSI. LEVEL OF EVIDENCE: Level II, prognostic study.

BACKGROUND: Arthrofibrosis following total knee arthroplasty (TKA) and adhesive capsulitis (AC) of the shoulder develop via a similar pathologic process. The purpose of this study was to examine the relationship between these two conditions. METHODS: This was a retrospective cohort study using a large nationwide claims database. Patients who had a history of shoulder AC prior to TKA were compared to TKA patients who did not have AC history comparing rates of postoperative stiffness, manipulation under anesthesia (MUA), arthroscopic lysis of adhesions (LOAs), and revision arthroplasty at postoperative timepoints (3 months, 6 months, 1 year, and 2 years). RESULTS: Within 3 months, 6 months, 1 year, and 2 years of their TKAs, patients who had a history of AC prior to TKA were significantly more likely to experience stiffness (OR [odds ratio] = 1.29, 1.28, 1.32, and 1.36, respectively) and LOAs (OR = 6.78, 3.65, 2.99, and 2.81, respectively). They also showed increased risk of MUA within 6 months, 1 year, and 2 years (OR = 1.15, 1.15, and 1.16, respectively) of their TKAs. Patients having a preoperative diagnosis of AC did not have an increased risk of undergoing revision surgery 1 year or 2 years after their TKAs (P > .05). CONCLUSIONS: Patients diagnosed with AC prior to TKA experience higher rates of postoperative stiffness, resulting in additional interventions such as MUA and LOAs. These findings identify a particularly high-risk patient population that may benefit from additional interventions prior to and following TKA. LEVEL OF EVIDENCE: This is a level III prognostic study.

BACKGROUND: The cellular mechanisms underlying excess scar tissue formation in arthrofibrosis following total knee arthroplasty (TKA) are well-described. Angiotensin receptor blockers (ARB), particularly losartan, is a commonly prescribed antihypertensive with demonstrated antifibrotic properties. This retrospective study aimed to assess the rates of 1- and 2-year postoperative complications in patients who filled prescriptions for ARBs during the 90 days after TKA. METHODS: Patients undergoing primary TKA were selected from a large national insurance database, and the impact of ARB use after TKA on complications was assessed. Of the 1,299,106 patients who underwent TKA, 82,065 had filled at least a 90-day prescription of losartan, valsartan, or olmesartan immediately following their TKA. The rates of manipulation under anesthesia (MUA), arthroscopic lysis of adhesions (LOA), aseptic loosening, periprosthetic fracture, and revision at 1 and 2 years following TKA were analyzed using multivariable logistic regressions to control for various comorbidities. RESULTS: ARB use was associated with decreased rates of MUA (odds ratio [OR] = 0.94, 95% confidence interval (CI), 0.90 to 0.99), arthroscopy/LOA (OR = 0.86, 95% CI, 0.77 to 0.95), aseptic loosening (OR = 0.71, 95% CI, 0.61 to 0.83), periprosthetic fracture (OR = 0.58, 95% CI, 0.46 to 0.71), and revision (OR = 0.79, 95% CI, 0.74 to 0.85) 2 years after TKA. CONCLUSIONS: ARB use throughout the 90 days after TKA is associated with a decreased risk of MUA, arthroscopy/LOA, aseptic loosening, periprosthetic fracture, and revision, demonstrating the potential protective abilities of ARBs. Prospective studies evaluating the use of ARBs in patients at risk for postoperative stiffness would be beneficial to further elucidate this association.

BACKGROUND: Vitamin D has been proven experimentally to affect musculoskeletal health. The purpose of this study was to identify the relationship between vitamin D deficiency and patellar instability. HYPOTHESIS: Vitamin D deficiency is associated with an increased risk of experiencing primary patellar instability and recurrent patellar dislocation after primary surgical stabilization. STUDY DESIGN: Retrospective comparative study. LEVEL OF EVIDENCE: Level 3. METHODS: A 1:1 matched retrospective study of 328,011 patients diagnosed with vitamin D deficiency was performed using the PearlDiver database. Incidence of primary patellar instability was calculated according to sex and age. Rates of primary patellar instability and surgical stabilization for recurrent dislocation were calculated with sex- and age-specific stratifications. Multivariable logistic regression was used to compare the rates of primary injury and recurrent stabilization while controlling for demographics and medical comorbidities. RESULTS: A total of 656,022 patients were analyzed. The overall 1-year incidence rate of patellar instability in patients with vitamin D deficiency was 82.6 per 100,000 person-years (95% CI, 73.2-92.9), compared with 48.5 (95% CI, 41.4-56.5) in the matched control. Women were significantly more likely to experience primary patellar instability within 1 (adjusted odds ratio [aOR] = 1.45; 95% CI, 1.12-1.88) and 2 years (aOR, 1.31; 95% CI, 1.07-1.59) of hypovitaminosis D diagnosis. Patients aged 10 to 25 years with hypovitaminosis D were at greater risk of requiring recurrent patellar stabilization for both men (aOR, 2.48; 95% CI, 1.06-5.80) and women (aOR, 1.77; 95% CI, 1.04-3.02). CONCLUSION: Patients diagnosed with vitamin D deficiency experienced higher rates of primary patellar instability and have greater risk of requiring recurrent surgical stabilization for subsequent dislocations. CLINICAL RELEVANCE: These results suggest that monitoring and proactively treating vitamin D deficiency in the physically active patient may lower the risk of suffering primary patellar instability or recurrence after surgical stabilization.

Posttraumatic osteoarthritis (PTOA) arises secondary to joint injuries and is characteristically driven by inflammatory mediators. PTOA is often studied in the setting of ACL tears. However, a wide range of other injuries also lead to PTOA pathogenesis. The purpose of this study was to characterize the morphological changes in the uninjured ACL in a PTOA inflammatory environment. We retrospectively reviewed 14 ACLs from 13 Yucatan minipigs, 7 of which had undergone our modified intra-articular drilling (mIAD) procedure, which induced PTOA through inflammatory mediators. Seven ACLs were harvested from mIAD minipigs (PTOA) and seven ACLs from control minipigs with no cartilage degeneration (non-PTOA). ACL degeneration was evaluated using histological scoring systems. IL-1ß, NF-κB, and TNF-α mRNA expression in the synovium was measured using qRT-PCR. PTOA minipigs demonstrated significant ACL degeneration, marked by a disorganized extracellular matrix, increased vascularity, and changes in cellular shape, density, and alignment. Furthermore, IL-1ß, NF-κB, and TNF-α expression was elevated in the synovium of PTOA minipigs. These findings demonstrate the potential for ACL degeneration in a PTOA environment and emphasize the need for anti-inflammatory disease-modifying therapies following joint injury.

INTRODUCTION: With the advent of virtual interviews and the increasing accessibility of internet resources, students increasingly rely on program websites for residency application decisions. In this cross-sectional study, we evaluated the presence of diversity or inclusion information in the least diverse US specialties' residency program websites, including dermatology, orthopedic surgery, otolaryngology, plastic surgery, and urology residency programs. METHODS: Two authors independently reviewed each Accreditation Council for Graduate Medical Education-accredited non-military US residency program website and ranked the websites' diversity and inclusion information using six pre-determined criteria based on previous studies in the literature. RESULTS: This study reveals that more than half of residency programs of each specialty met zero of the diversity and inclusion information criteria. CONCLUSIONS: Residency program websites in the least diverse specialties are lacking important information for prospective applicants that may help signal programs' commitment to inclusivity and attract a diverse candidate pool.

OBJECTIVES: Animal models are needed to reliably separate the effects of mechanical joint instability and inflammation on posttraumatic osteoarthritis (PTOA) pathogenesis. We hypothesized that our modified intra-articular drilling (mIAD) procedure induces cartilage damage and synovial changes through increased inflammation without causing changes in gait. METHODS: Twenty-four Yucatan minipigs were randomized into the mIAD (n=12) or sham control group (n=12). mIAD animals had two osseous tunnels drilled into each of the tibia and femur adjacent to the anterior cruciate ligament (ACL) attachment sites on the left hind knee. Surgical and contralateral limbs were harvested 15 weeks post-surgery. Cartilage degeneration was evaluated macroscopically and histologically. Synovial changes were evaluated histologically. Interleukin-1 beta (IL-1ß), nuclear factor kappa B (NF-κB), and tumor necrosis factor alpha (TNF-α) mRNA expression levels in the synovial membrane were measured using quantitative real-time polymerase chain reaction. IL-1ß and NF-κB levels in chondrocytes were assessed using immunohistochemistry. Load asymmetry during gait was recorded by a pressure-sensing walkway system before and after surgery. RESULTS: The mIAD surgical knees demonstrated greater gross and histological cartilage damage than contralateral (P<.01) and sham knees (P<.05). Synovitis was present only in the mIAD surgical knee. Synovial inflammatory marker (IL-1ß, NF-κB, and TNF-α) expression was three times higher in the mIAD surgical knee than the contralateral (P<.05). Chondrocyte IL-1ß and NF-κB levels were highest in the mIAD surgical knee. In general, there were no significant changes in gait. CONCLUSIONS: The mIAD model induced PTOA through inflammation without affecting gait mechanics. This large animal model has significant applications for evaluating the role of inflammation in PTOA and for developing therapies aimed at reducing inflammation following joint injury.
RESUMO
Purpose: To identify the 25 most-cited articles on humeral avulsion of the glenohumeral ligament (HAGL) lesions and characterize them based on number of citations, citation density, source journal, year of publication, geographic origin, article type, and level of evidence. Methods: The Science Citation Index Expanded database was queried for all possible publications regarding HAGL lesions. The 25 most-cited articles from 1976 to 2021 relevant to the topic were selected for further analysis. Articles were characterized based on the number of citations, citation density, year of publication, source journal, country of origin, article type, article subtype, and level of evidence. Results: The number of citations for individual articles ranged from 21 to 182 (mean ± standard deviation: 44.72 ± 36.87). Ten countries contributed to the 25 most cited articles, with 14 of the 25 (56%) articles published in the United States. Furthermore, the top 25 cited articles were published in 9 journals, with the majority in Arthroscopy-The Journal of Arthroscopic and Related Surgery (n = 15, 60%). There were 15 (60%) articles classified as "Clinical," 9 (36%) as "Review/Expert Opinion," and 1 (4%) as "Basic Science." All clinical studies met the standard for level IV evidence. Conclusions: This bibliometric analysis provides a list of the 25 most cited articles related to HAGL lesions, providing a reference of impactful articles for medical educators. The lack of high level of evidence "Clinical" studies demonstrates that higher-quality research is needed to establish guidelines for the treatment and management of HAGL lesions. Clinical Relevance: A list of the 25 most-cited articles regarding recurrent glenohumeral instability can serve as a comprehensive reference for practitioners, educators, researchers, and orthopaedic trainees.
RESUMO
BACKGROUND: In 2018, the City of Providence introduced a program in which electronic scooters were deployed for public use. We aim to characterize the burden of craniofacial injuries associated with these scooters. METHODS: A retrospective review was conducted of all patients consulted to the plastic surgery service for evaluation of craniofacial injury between September 2018 and October 2022. Data pertaining to patient sociodemographics, site and time of injury, and craniofacial trauma were recorded. RESULTS: Twenty-five patients sustaining craniofacial trauma were identified over a four-year period. Most patients required soft tissue repair (64%) and bony fractures were sustained by approximately half of all patients (52%). Admission to ICU was uncommon (16%), and there were no fatalities. CONCLUSIONS: The incidence of craniofacial injury from electronic scooter use is low. However, these injuries may involve extensive surgical reconstruction and ICU admission. We advise the City of Providence to optimize best safety practices and monitoring to minimize risk.

PURPOSE: To characterize the association between a diagnosis of hypovitaminosis D and primary anterior cruciate ligament (ACL) tear, primary anterior cruciate ligament reconstruction (ACLR), and revision ACLR in different sex and age cohorts. METHODS: In this retrospective cohort study of the PearlDiver claims database, records were queried between January 1, 2011, and October 31, 2018 for all patients aged 10 to 59 years who received a diagnosis of hypovitaminosis D. Rates of primary ACL tears, primary reconstruction, and revision reconstruction were calculated for sex- and age-specific cohorts and compared with a control of patients without a diagnosis of hypovitaminosis D. Incidence rates for primary ACL injuries were calculated, and multivariable logistic regression was used to compare rates of ACL injury, primary reconstruction, and revision reconstruction while controlling for age, sex, Charlson Comorbidity Index, and several other comorbidities. RESULTS: Among the 328,011 patients (mean age 41.9 ± 12.6 years, 65.8% female) included in both the hypovitaminosis D and control cohorts, the incidence of ACL tears was 115.2 per 100,000 person-years (95% confidence interval [CI] 107.2-123.7) compared with 61.0 (95% CI 55.2-67.2) in the demographic- and comorbidity-matched control cohort. The study cohort was significantly more likely to suffer an ACL tear over a 1- (aOR 1.67, 95% CI 1.41-1.99, P < .001) and 2-year (aOR 1.81, 95% CI 1.59-2.06, P < .001) period. This trend remained for both male patients at the 1- (aOR 1.66, 95% CI 1.29-2.14, P < .001) and 2-year (aOR 1.68, 95% CI 1.37-2.06, P < .001) mark and female patients at the 1- (aOR 1.69, 95% CI 1.33-2.14, P < .001) and 2-year (aOR 1.80, 95% CI 1.51-2.14, P < .001) mark. Finally, patients with vitamin D deficiency had a significantly increased likelihood of undergoing a revision ACLR within 2 years of a primary reconstruction (aOR 1.28, 95% CI 1.05-1.55, P = .012). CONCLUSIONS: This study reports an association between patients previously diagnosed with hypovitaminosis D and significantly increased rates of both index ACL tears (81% increase within 2 years of diagnosis) and revision ACLR (28% within 2 years). These results identify a population with increased odds of injury and provide valuable knowledge as we expand our understanding of the relationship between vitamin D and musculoskeletal health. LEVEL OF EVIDENCE: Level III, retrospective database study.

Sarcopenia is a state of catabolic muscle wasting prevalent in geriatric patients. Likewise, osteoarthritis is an age-related musculoskeletal disease affecting patients with similar demographics. Late-stage hip osteoarthritis is often treated with total hip arthroplasty (THA). As sarcopenia influences the surgical outcomes, this study aimed to assess the impact of sarcopenia on the outcomes of THA. A 1:3 matched case-control study of sarcopenic to control patients was performed using a large national database. In total, 3992 patients were analyzed. Sarcopenic patients undergoing THA were more likely to experience dislocation (odds ratio (OR) = 2.19, 95% confidence interval (CI) 1.21-3.91) within 1 year of THA. Furthermore, sarcopenic patients had higher urinary tract infection rates (OR = 1.79, CI 1.32-2.42) and a greater risk of 90-day hospital readmission (hazard ratio (HR) = 1.39, CI 1.10-1.77). Sarcopenic patients experienced more falls (OR = 1.62, CI 1.10-2.39) and fragility fractures (OR = 1.77, CI 1.34-2.31). Similarly, sarcopenic patients had higher day of surgery costs (USD 13,534 vs. USD 10,504) and 90-day costs (USD 17,139 vs. USD 13,394) compared with the controls. Ultimately, sarcopenic patients undergoing THA experience higher rates of postoperative complications and incur greater medical costs. Given the potential risks, orthopedic surgeons may consider treating or reducing the severity of sarcopenia before surgery.
RESUMO
OBJECTIVE: Sarcopenia, characterized by decreased muscle mass and function, is projected to affect more than 200 million people worldwide by 2060. This study aimed to evaluate the rates of short-term complications following lumbar spine arthrodesis in patients with and without a recent diagnosis of sarcopenia. METHODS: The PearlDiver database was queried to evaluate all patients who underwent index lumbar spine arthrodesis from 2012 to 2019. Multivariate logistic regression was used to compare rates of 90-day surgical and medical complications. Kaplan-Meier analysis was performed to compare cumulative rates of reoperation and all-cause hospital readmission. Two sample t testing was used to compare costs of care. Statistical significance was set at P < 0.05 a priori. RESULTS: Of 239,953 patients undergoing lumbar spine arthrodesis, 1087 had a recent diagnosis of sarcopenia (0.45%) before surgery. Patients with sarcopenia were significantly more likely to experience a urinary tract infection (odds ratio = 1.41, P = 0.035) and undergo incision and drainage (odds ratio = 2.66, P = 0.010) within 90 days after lumbar arthrodesis. Patients with sarcopeniawere at a 24% greater risk of 1-year all-cause hospital readmission. The 90-day cost of care was significantly greater in patients with sarcopenia ($37,689.86 vs. $26,635.72; P < 0.001). CONCLUSIONS: In patients undergoing lumbar spine arthrodesis, sarcopenia is associated with an increased risk of postoperative complications, including increased costs of care. Spine surgeons should consider screening patients for sarcopenia preoperatively and counsel them regarding their increased risk of complications. Additionally, surgeons may consider preoperative optimization, like the management of low bone density.

BACKGROUND: With the increasing utilization of total knee arthroplasty (TKA) in a continually aging US population, the number of patients who have low bone mineral density who undergo TKA may concomitantly increase. This study aimed to assess the rates of short-term complications following TKA in patients who did and did not have a recent history of a prior fragility fracture. METHODS: A matched retrospective cohort study analyzing 48,796 patients was performed using a national database to determine the impact of a preceding fragility fracture on rates of short-term complications following TKA. The rates of complications at 1 and 2 years post-TKA were analyzed using multivariate logistic regressions. RESULTS: Prior fragility fracture was associated with increased rates of 1-year hospital readmissions (hazard ratio = 1.30, 95% CI, 1.22-1.38), periprosthetic fractures (odds ratio [OR] = 2.72, 95% CI, 1.89-3.99), non-infection-related revisions (OR = 1.32, 95% CI, 1.09-1.60), secondary fragility fractures (OR = 4.62, 95% CI, 4.19-5.12), prosthesis dislocations (OR = 1.76, 95% CI, 1.22-2.56), prosthesis instabilities (OR = 1.64, 95% CI, 1.25-2.15), and periprosthetic infections (OR = 1.49, 95% CI, 1.29-1.71), with similar trends in implant-related complications also seen at the 2-year mark. Patients who filled a prescription for osteoporosis pharmacotherapy had clinically similar rates of these complications compared to those who did not. CONCLUSION: Sustaining a fragility fracture prior to TKA is associated with an increased risk of hospital readmission and significant implant-related postoperative complications, potentially increasing the morbidity and mortality of TKA in these patients.

BACKGROUND: Psychiatric comorbidities have been shown to influence outcomes of various orthopedic pathologies. This study aimed to compare rates of delayed scaphoid union and surgical intervention for fractures in patients with and without comorbid psychiatric diagnoses. METHODS: A matched retrospective cohort study was performed using the PearlDiver database to determine the association of depression, anxiety, bipolar disorder, and schizophrenia with delayed union rates within 3 and 6 months and rates of nonacute surgical intervention (fixation or grafting) within 6 and 12 months of scaphoid fracture. Analyses were completed using multivariate logistic regression. RESULTS: Among 20 340 patients, a comorbid psychiatric diagnosis was associated with increased rates of delayed scaphoid union at 3 months (odds ratio [OR] = 1.29; 95% confidence interval [CI], 1.14-1.45) and 6 months (OR = 1.23; 95% CI, 1.10-1.38). At 3 months, women with any psychiatric disorder (OR = 1.58; 1.29-1.66), depression (OR = 1.68; 1.31-2.17), and schizophrenia (OR = 5.32; 95% CI, 1.06-26.79) were more likely to experience delayed union, with similar results at 6 months. Men with bipolar disorder experienced increased delayed union rates at 6 months (OR = 1.40; 1.03-1.91). A comorbid psychiatric diagnosis (OR = 1.10; 1.01-1.20) was associated with increased rates of surgical intervention, whereas schizophrenia was associated with decreased rates (OR = 0.58; 0.34-0.99). CONCLUSION: Patients with comorbid psychiatric conditions experienced increased rates of delayed scaphoid union. These results underscore the importance of understanding factors that may place patients at risk of impaired recovery.
