RESUMO
BACKGROUND: Dog walking is associated with a significant injury burden among adults, but the risk of injury associated with dog walking among children is poorly understood. This study describes the epidemiology of children treated at US emergency departments for injuries related to leash-dependent dog walking. METHODS: The National Electronic Injury Surveillance System (NEISS) database was retrospectively analyzed to identify children (5 to 18 years of age) presenting to US emergency departments between 2001 and 2020 with dog walking-related injuries. Primary outcomes included annual estimates of injury incidence, injury characteristics, and risk factors for fracture or traumatic brain injury (TBI). Weighted estimates, odds ratios (ORs), and 95% confidence intervals (CIs) were generated using NEISS sample weights. RESULTS: An estimated 35,611 children presented to US emergency departments with injuries related to dog walking. The mean age of patients was 11 years, and most patients were girls (63%). Over half (55%) of injuries were orthopaedic, and patients commonly injured their upper extremity (57%) and were hurt while falling when pulled or tripped by the leash (55%). The most frequent injuries were wrist strain/sprain (5.6%), finger strain/sprain (5.4%), and ankle strain/sprain (5.3%). On multivariable analysis, injured children aged 5 to 11 years were more likely to have sustained a TBI (OR: 3.2, 95% CI: 1.1-9.7) or fracture (OR: 1.6; 95% CI: 1.1-2.3). Boys were more likely than girls to have experienced a fracture (OR: 2.0, 95% CI: 1.3-2.5). CONCLUSIONS: Dog walking-related injuries in children are primarily orthopaedic and involve the upper extremity. Younger children and boys are at greater risk for serious dog walking-related injuries. LEVEL OF EVIDENCE: Level III.

BACKGROUND: The influence of position of the humeral tray (inlay or onlay) on clinical outcomes in reverse shoulder arthroplasty (RSA) is a topic of debate. The purpose of this study was to compare clinical and radiographic outcomes of patients with cuff tear arthropathy treated with RSA systems with inlay or onlay humeral tray design, similar neck-shaft angles, and lateralized glenospheres. METHODS: This was a retrospective study of prospectively obtained data from 1 tertiary care center. We identified all patients who underwent primary RSA between 2009 and 2017 (N = 511). We included 102 patients with diagnosed cuff tear arthropathy treated with RSA prostheses with a lateralized glenosphere and 135° neck-shaft angle (with either an inlay or onlay humeral tray design) who had a minimum of 2 years of follow-up (mean, 44 months; range, 24-125 months). Sixty-three patients (62%) had an inlay humeral tray (inlay group) and 39 (38%) had an onlay tray (onlay group). All patients underwent preoperative and postoperative evaluations, including measures of patient-reported outcomes (PROs), shoulder range of motion (ROM) testing, and radiographic imaging. Clinical relevance of changes in PROs and ROM was evaluated using published values for minimal clinically important differences. RESULTS: The 2 groups did not differ by demographic characteristics except for a higher proportion of women in the inlay group (75%) than in the onlay group (56%) (P = .04). Preoperative PROs and ROM were not significantly different between groups. At final follow-up, PROs and ROM were not different between groups in terms of statistical significance or clinical relevance. We found no significant differences in the rate of baseplate loosening (inlay, 3.2% vs. onlay, 5.1%, P = .63), revision surgery (inlay, 0% vs. onlay 5.1%, P = .07), acromial stress fracture (inlay, 3.2% vs. onlay, 5.1%, P = .63), prosthesis dislocation (inlay, 0% vs. onlay, 2.6%, P = .20), or scapular notching (inlay, 21% vs. onlay, 7.7%, P = .08). CONCLUSION: At 2-year minimum follow-up, the position of the humeral tray in RSA prostheses (either inlay or onlay) for cuff tear arthropathy was not associated with PROs, shoulder ROM, or rates of complications, including baseplate loosening, acromial stress fracture, and scapular notching.
RESUMO
Arthroscopic distal clavicle excision (DCE) is a reliable procedure to treat acromioclavicular joint arthritis. Typically, only 1 to 2 cm of distal clavicle should be removed. Resection of too much bone can lead to instability of the joint or lack of support to the shoulder. We describe 2 patients who had excessive clavicular bone removed arthroscopically, leading to irreparable clavicular pain and dysfunction. The 2 female patients, ages 56 and 60 years, presented to our clinic with continued pain after DCE. Both had pain intractable with nonoperative treatment and loss of range of motion of the shoulder. Radiographs revealed a distal clavicle defect of 7.5 cm in 1 patient. The second patient had a 2-cm distal clavicular defect with an adjacent 2-cm clavicle bone fragment between the defect and residual clavicle shaft. Both underwent surgery with subtotal claviculectomy for pain control. During surgery, 1 patient had a subclavian vein requiring vascular repair. After 1 year of follow-up, both patients had reduced but residual pain and restricted range of motion. Only 1 patient could rejoin her preinjury occupation. Neither patient could continue with preinjury recreational sports. Excessive removal of the distal clavicle during DCE can result in continued pain and disability of the shoulder. Methods to visualize the anatomy of the distal clavicle and its articulation to the acromion should be considered when performing this operation arthroscopically. Reoperation to remove subtotal clavicle has good clinical outcomes but may lead to serious complications due to the proximity to major neurovascular structures. [Orthopedics. 2024;47(1):e57-e60.].

BACKGROUND: Our purpose was to evaluate a custom reverse total shoulder arthroplasty glenoid baseplate for severe glenoid deficiency, emphasizing the challenges with this approach, including short-term clinical and radiographic outcomes and complications. METHODS: This was a single-institution, retrospective series of 29 patients between January 2017 and December 2022 for whom a custom glenoid component was created for extensive glenoid bone loss. Patients were evaluated preoperatively and at intervals for up to 5 years. All received preoperative physical examinations, plain radiographs, and computed tomography (CT). Intra- and postoperative complications are reported. RESULTS: Of 29 patients, delays resulted in only undergoing surgery, and in three of those, the implant did not match the glenoid. For those three, the time from CT scan to implantation averaged 7.6 months (range, 6.1-10.7 months), compared with 5.5 months (range, 2-8.6 months) for those whose implants fit. In patients with at least 2-year follow-up (n=9), no failures occurred. Significant improvements were observed in all patient-reported outcome measures in those nine patients (American Shoulder and Elbow Score, P<0.01; Simple Shoulder Test, P=0.02; Single Assessment Numeric Evaluation, P<0.01; Western Ontario Osteoarthritis of the Shoulder Index, P<0.01). Range of motion improved for forward flexion and abduction (P=0.03 for both) and internal rotation up the back (P=0.02). Pain and satisfaction also improved (P<0.01 for both). CONCLUSIONS: Prolonged time (>6 months) from CT scan to device implantation resulted in bone loss that rendered the implants unusable. Satisfactory short-term radiographic and clinical follow-up can be achieved with a well-fitting device. Level of evidence: III.
RESUMO
PURPOSE: Image-free handheld robotic-assisted total knee arthroplasty (RATKA) has shown to achieve desired limb alignment compared to conventional jig-based instrumented total knee arthroplasty (CTKA). The aim of this prospective randomized controlled trial (RCT) was to evaluate the accuracy of a semi-autonomous imageless handheld RATKA compared to CTKA in order to achieve the perioperative planned target alignment of the knee postoperatively. METHODS: Fifty-two patients with knee osteoarthritis were randomized in 1:1 ratio to undergo unilateral CTKA or an imageless handheld RATKA. A full-length lower limb CT-scan was obtained pre- and 6-week postoperative. The primary outcomes were radiologic measurements of achieved target hip-knee-ankle axis (HKA-axis) and implant component position including varus and external rotation and flexion of the femur component, and posterior tibial slope. The proportion of outliers in above radiographic outcomes, defined as > 3° deviation in postoperative CT measurements as compared to perioperative planned target, were also noted. Knee phenotypes were compared with use of the Coronal Plane Alignment of the Knee (CPAK) classification. RESULTS: Baseline conditions were comparable between both groups. The overall proportion and percentage of outliers (n = 38, 24.4% vs n = 9, 5.8%) was statistically significant (p < 0.001) in favor of RATKA. The achieved varus-valgus of the femoral component (varus 1.3° ± 1.7° vs valgus - 0.1° ± 1.9°, p < 0.05) with statistically significant less outliers (0% vs 88.5%, p < 0.01), the achieved HKA-axis (varus 0.4° ± 2.1° vs valgus - 1.2° ± 2.1°, p < 0.05) and the posterior tibial slope (1.4° ± 1.1° vs 3.2° ± 1.8°, p < 0.05) were more accurate with RATKA. The most common postoperative CPAK categories were type II (50% CTKA vs 61.5% RATKA), type I (3.8% CTKA vs 23.1% RATKA) and type V (26.9% CTKA vs 15.4% RATKA). CPAK classification III was only found in CTKA (19.2%). Type VI, VII, VIII, and IX were rare in both populations. CONCLUSIONS: The present trial demonstrates that an imageless handheld RATKA system can be used to accurately perioperatively plan the desired individual component implant positions with less alignment outliers whilst aiming for a constitutional alignment. LEVEL OF EVIDENCE: I.

Introduction: The common peroneal nerve (CPN) palsy in military personnel due to chronic exertional compartment syndrome (CECS) is uncommon. There are no previous reports of treatment of this condition with simultaneous CPN and superficial peroneal nerve (SPN) neurolysis and compartment release. Case Report: An 18-year-old military recruit presented with complete CPN palsy after sitting cross-legged for 2 h in training. After 3 months of failed non-operative treatment, a clinical diagnosis of CECS with CPN palsy was made and the patient was treated with simultaneous CPN and SPN neurolysis and release of the anterior and lateral leg compartments. The patient had full recovery at 6 months post-operative period and returned to sports at 1 year follow-up. Conclusion: This case report of a young military recruit with CPN palsy after prolonged cross-legged sitting in the setting of CECS demonstrates successful treatment with simultaneous CPN and SPN neurolysis and anterior and lateral compartment release. Future studies should explore the efficacy of this treatment option and prevention strategies of CPN palsy in military personnel.
RESUMO
Introduction: As the utilization of total shoulder arthroplasty (TSA) increases, it is essential to identify risk factors associated with postoperative complications. Urinary tract infection (UTI) is one such example. Our objective is to identify whether UTI is associated with increased rates of prosthetic joint infection (PJI) and determine whether its treatment reduces PJI rates. Methods: Patients who underwent primary TSA for glenohumeral osteoarthritis between 2010 and 2019 with minimum two-year follow-up were identified in a national database (PearlDiver Technologies) using Current Procedural Terminology and International Classification of Diseases codes. These patients were stratified into two cohorts: those with preoperative UTI within two weeks of TSA and those without. The preoperative UTI cohort was stratified into those treated and those untreated prior to TSA. Univariate and multivariable analyses were performed. Results: Following multivariable analysis, there were significantly higher odds of postoperative anemia, pulmonary embolism, and death in the UTI cohort. Comparing treated to untreated UTI, there were no significant differences in multivariable analysis for any 90-day medical or two-year surgical complications. Discussion: This study showed that UTI was not associated with increased rates of PJI. UTI was, however, associated with postoperative medical complications that surgeons should be aware of.
RESUMO
PURPOSE: The purpose of this study was to compare the clinical and radiological outcomes in patients who underwent simultaneous bilateral total knee arthroplasty (SB-TKA) using either robotic-assisted TKA (RA-TKA) or conventional TKA (C-TKA). METHODS: Included were the patients who underwent SB-TKA between January 2018 and January 2020 and had a minimum follow-up of 2 years. Of 151 patients included, 117 patients were operated using an image-free handheld robotic sculpting system (RA-TKA group) and 34 patients operated using conventional instrumentation (C-TKA group). The key outcomes noted were multiple patient-reported outcomes (PROs), adverse events, and radiological outcomes. Two investigators independently measured the radiological outcomes on pre- and post-operative radiographs in coronal plane (medial proximal tibial angle [MPTA] and anatomic lateral distal femoral angle [aLDFA]) and sagittal plane (posterior tibial slope [PTS] and posterior condylar offset [PCO]). The chi-square test was used to examine categorical variables. Student's t test was used to analyze the continuous variables. RESULTS: Patients in both groups were similar in baseline characteristics (gender, body mass index, incidence of comorbidities, and length of hospital stay) except that RA-TKA group patients younger (66.7 ± 8.9 vs 70.4 ± 10.5, P = 0.037) than C-TKA group. The operative time was longer in RA-TKA group as compared to C-TKA (189.3 ± 37.1 vs 175.0 ± 28.2, P = 0.040). The final PROs at each were similar between the two groups (P > 0.05). The values of PROs at final follow-up in RA-TKA compared to C-TKA were VAS pain (0.4 ± 0.9 vs 0.4 ± 0.5), KOOS-JR (89.3 ± 5.8 vs 87.1 ± 5.3), and physical (55.9 ± 2.8 vs 55.4 ± 3.2), mental (61.1 ± 4.4 vs 60.2 ± 4.7) component of VR-12 scores, and KSS satisfaction (37.5 ± 1.1 vs 37.1 ± 2.2) (all P > 0.50 or non-significant [n.s.]). While one patient in RA-TKA required revision of femoral component for peri-prosthetic fracture, none of the patient in conventional group were revised (0.85% vs 0%, P = n.s.). The proportion of patients with outliers in RA-TKA group was lower for aLDFA (2.6% vs 22.1%, P < 0.01) and PTS (0% vs 35%, P < 0.01). CONCLUSION: This comparative study in patients undergoing SB-TKA found reduction of outliers in femoral and tibial implant positioning with RA-TKA as compared to C-TKA. There were no differences in both groups for pain, function, and satisfaction at a minimum of 2 years of follow-up. LEVEL OF EVIDENCE: III Therapeutic Study.

One of the technical challenges during arthroscopic rotator cuff repair is bone deficiency in proximal humerus to get adequate fixation of suture anchors. The typical scenarios that result in bone deficiency at rotator cuff footprint are older individuals, females, osteoporosis, and revision rotator cuff repairs with failed anchors from previous surgery. One of the ways to secure fixation of suture anchors in deficient bone is augmentation with polymethyl methacrylate cement. We present a stepwise technique of cement augmentation of suture anchor during arthroscopic rotator cuff repair to achieve secure fixation of suture anchor and avoid spillage of cement in the subacromial space.
RESUMO
PURPOSE: Dog walking is a popular daily activity, yet information regarding its injury burden is limited. This study describes the epidemiology of injuries related to leash-dependent dog walking among adults presenting to US emergency departments from 2001 to 2020. METHODS: A retrospective analysis was performed using the National Electronic Injury Surveillance System database to identify adults (≥18 yr) presenting to US emergency departments with leash-dependent dog walking-related injuries between 2001 and 2020. Outcomes included annual estimates of injury incidence, injury characteristics, and risk factors for sustaining a fracture or traumatic brain injury (TBI). Weighted estimates and 95% confidence intervals (CI) were generated using National Electronic Injury Surveillance System sample weights. RESULTS: Between 2001 and 2020, an estimated 422,659 adults presented to US emergency departments with injuries related to leash-dependent dog walking. The annual incidence increased more than fourfold during this period ( n = 7282 vs n = 32,306, P < 0.001). Most patients were women (75%) and adults age 40 to 64 yr (47%), with a mean age of 53 ± 0.5 yr. Patients commonly injured their upper extremity (51%) and were injured while falling when pulled or tripped by the leash (55%). The three most common injuries were finger fracture (6.9%), TBI (5.6%), and shoulder sprain/strain (5.1%). On multivariate analysis, fracture risk among dog walkers was higher in adults age ≥65 yr (odds ratio [OR], 2.1; 95% CI, 1.8-2.5) and women (OR, 1.5; 95% CI, 1.3-1.7). Risk of TBI was also elevated among older dog walkers (OR, 1.6; 95% CI, 1.3-2.0). CONCLUSIONS: Dog walking is associated with a considerable and rising injury burden. Dog owners should be informed of this injury potential and advised on risk-reduction strategies.
RESUMO
PURPOSE: In order to minimize errors during achieving the targeted alignment of the total knee arthroplasty (TKA) components, robotic-assisted surgery has been introduced with the aim to help surgeons to improve implant survival, clinical outcomes, and patient satisfaction. The primary goal of this paper is to highlight surgical tips and tricks on how to achieve functional alignment (FA) through intra-operative boney mapping, numeric gap, and alignment data, using the next generation of imageless robotic surgical systems. METHOD: This retrospective case-series contains planned and achieved data on the FA and joint gap data obtained from 526 patients captured and assessed with use of a semi-autonomous imageless handheld robotic sculpting systems. All patients were operated upon by two experienced TKA surgeons. RESULTS: The mean difference between planned and achieved alignment was 1.46° (≥ 7° varus group), 1.02° (< 7° varus group), 1.16° (< 7° valgus group), and 1.43° (≥ 7° valgus group). The mean observed planned and achieved extension and flexion gaps were below 1.47 mm for medial extension gaps, 1.12 mm for the lateral extension gaps, 1.4 mm for the medial flexion gaps, and 1.16 mm for the lateral flexion gaps. CONCLUSION: Analysis of these first cases highlights the capability of the next generation of imageless robotic-assisted total knee replacement using a semi-autonomous handheld robotic sculpting to maintain accuracy of the desired alignment. The system allows the surgeon to choose freely their own alignment philosophy while maintaining efficiency.

Introduction: Avulsion fracture of the ischial tuberosity is uncommon. Patients typically present with symptoms consistent with hamstring strain. The purpose of this case report is to describe an avulsion fracture of the ischial tuberosity and subsequent recovery in an athlete with an endocrine disorder. Case Description: A 15-year-old United States of America Gymnastics level 9 gymnast presented with right hamstring pain after regular practice. She had been diagnosed with isolated growth hormone deficiency at age 4 and was treated with growth hormone replacement therapy until age 14. Six months before presentation, she experienced the insidious onset of dull, aching pain in her right hamstring, near the junction of the thigh and buttocks, that was believed to be the result of a chronic hamstring strain. The pain increased gradually over a year and was relieved with rest, massage, and dry needling. Two days before presentation, she felt a "snap" and pain while performing a switch leap during regular practice. She had sharp localized pain in the proximal hamstring with walking and sitting. She was diagnosed with a minimally displaced avulsion fracture of the ischial tuberosity. Outcome: With nonoperative treatment, the fracture healed at three months, which is longer than the expected six weeks. Although return to sports is expected three months after this injury, it did not occur until six months in this patient. She was unable to participate in competitive level 9 gymnastics until 12 months after injury. Discussion: This case highlights that delayed recovery can occur after avulsion fracture of the ischial tuberosity in adolescent athletes with a history of growth hormone deficiency and treatment using growth hormone. Level of Evidence: 5.
RESUMO
BACKGROUND: The diagnosis of periprosthetic shoulder infection (PSI) in patients with a painful arthroplasty is challenging. Magnetic resonance imaging (MRI) may be helpful, but shoulder implant-induced metal artifacts degrade conventional MRI. Advanced metal artifact reduction (MARS) improves the visibility of periprosthetic bone and soft tissues. The purpose of our study was to determine the reliability, repeatability, and diagnostic performance of advanced MARS-MRI findings for diagnosing PSI. METHODS: Between January 2015 and December 2019, we enrolled consecutive patients suspected of having PSI at our academic hospital. All 89 participants had at least 1-year clinical follow-up and underwent standardized clinical, radiographic, and laboratory evaluations and advanced MARS-MRI. Two fellowship-trained musculoskeletal radiologists retrospectively evaluated the advanced MARS-MRI studies for findings associated with PSI in a blinded and independent fashion. Both readers repeated their evaluations after a 2-month interval. Interreader reliability and intrareader repeatability were assessed with κ coefficients. The diagnostic performance of advanced MARS-MRI for PSI was quantified using sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC). When applying the International Consensus Meeting (ICM) 2018 criteria, of the 89 participants, 22 (25%) were deemed as being infected and 67 (75%) were classified as being not infected (unlikely to have PSA and not requiring a surgical procedure during 1-year follow-up). RESULTS: The interreader reliability and intrareader repeatability of advanced MARS-MRI findings, including lymphadenopathy, joint effusion, synovitis, extra-articular fluid collection, a sinus tract, rotator cuff muscle edema, and periprosthetic bone resorption, were good (κ = 0.61 to 0.80) to excellent (κ > 0.80). Lymphadenopathy, complex joint effusion, and edematous synovitis had sensitivities of >85%, specificities of >90%, odds ratios of >3.6, and AUC values of >0.90 for diagnosing PSI. The presence of all 3 findings together yielded a PSI probability of >99%, per logistic regression analysis. CONCLUSIONS: Our study shows the clinical utility of advanced MARS-MRI for diagnosing PSI when using the ICM 2018 criteria as the reference standard. Although the reliability and diagnostic accuracy were high, these conclusions are based on our specific advanced MARS-MRI protocol interpreted by experienced musculoskeletal radiologists. Investigations with larger sample sizes are needed to confirm these results. LEVEL OF EVIDENCE: Diagnostic Level III . See Instructions for Authors for a complete description of levels of evidence.

CONTEXT: Speedball is an increasingly popular racquet sport played in more than 25 countries. Our objective was to describe injury incidence and patterns among Egyptian national-level speedball athletes. DESIGN: Descriptive epidemiological. METHODS: We conducted a survey of athletes who were registered with the Egyptian Speedball Federation during the 2018-2019 professional season. The survey inquired about injury types and athlete exposures (AEs). The response rate was 63% (100/160 athletes). Respondent ages ranged from 18 to 41 years. We analyzed demographic characteristics; number, location, and mechanism of injuries; treatment; and speedball participation time lost because of injury. RESULTS: Of 100 respondents, 65 reported having sustained at least one injury during the season for a total of 90 injuries and a rate of 4.7 injuries per 1000 AEs (95% confidence interval, 3.7 to 5.7). More injuries occurred during practice (77%) than during competition (23%). Thirty percent of respondents reported having missed a competition because of injury. The most frequent anatomic locations of injury were the shoulder (50%; 2.4/1000 AEs), elbow (14%; 0.68/1000 AEs), and low back (9%; 0.4/1000 AEs). The most frequently cited causes of injury were increased intensity of training (40%) and lack of warming up (18%). Seventy-seven percent of injured respondents underwent treatment by a health care professional, and 9% of these respondents underwent surgery. CONCLUSION: The shoulder was the most common anatomic location for injuries in speedball athletes. Our results suggest that attention should be directed toward sport-specific injury prevention and intervention strategies because speedball is a fast-growing sport in several countries.

Background: This study aimed to determine whether combined intravenous (IV) and intraarticular (IA) tranexamic acid (TXA) reduces blood loss and the requirement of blood transfusion compared to IA use alone in the middle eastern patients undergoing primary cemented unilateral total knee arthroplasty (TKA). Methods: The present study is a double-blind randomized controlled trial (RTC) comparing the efficacy of IA alone to combined IA and IV routes of TXA administration in patients undergoing primary cemented TKA using a tourniquet performed by two senior surgeons. There were 21 patients in the IA alone and 29 in the combined group. The primary outcome measure was blood transfusion requirement, hemoglobin drop, and the total estimated blood loss on day three of postoperative period. The secondary outcomes were complications including thromboembolic events, wound complications, periprosthetic infection, patient-reported outcomes (PROs) of pain visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and EuroQol 5-dimension (EQ-5D) as well as the range of motion (ROM) at one-year follow-up. Results: None of the patients in either of the comparison group required blood transfusion in the perioperative period. The drop in hemoglobin levels (2.1±1.0 vs. 2.2±1.1, P=0.84) and the total estimated blood loss (884±489 vs. 877±324, P=0.96) on the third postoperative day in the IA alone group showed no statistically significant difference compared to that in the combined group. Moreover, there were no complications noted in patients of either group. At one-year follow-up, there was no significant difference between the two comparison groups regarding the mean PROs of pain VAS, WOMAC, and EQ-5D, as well as ROM. Conclusion: According to the obtained results, this RCT in the middle eastern patient population found no additional benefit of TXA administration through combined IV and IA route over the IA alone in reducing the requirement of blood transfusion and the total blood loss. Further similar studies with larger sample sizes are needed to ascertain the ideal route of TXA administration in patients undergoing primary TKA.
RESUMO
BACKGROUND: Whether or how the position of the humeral tray (inlay or onlay) in reverse shoulder arthroplasty (RSA) affects outcomes is unclear. Our goal was to compare the clinical and radiographic results of RSA systems with inlay vs. onlay designs but with similar neck shaft angles (NSAs) and lateralized glenospheres. METHODS: We screened the institutional database at our tertiary academic center for patients who underwent primary RSA (with a lateralized glenosphere and a 135° NSA) from 2009 through 2017. The indication for surgery was glenohumeral osteoarthritis with glenoid bone loss (Walch classification A2, B2, B3, or C) and an intact rotator cuff. All patients were followed for a minimum of 2 years (mean, 47 months; range, 24-123 months). The humeral tray design was inlay for 79 patients and onlay for 71. All patients underwent preoperative and postoperative evaluations, including physical examination, radiography, and patient-reported outcome measures (visual analog scale for pain, American Shoulder and Elbow Surgeons score, Simple Shoulder Test, and Western Ontario Osteoarthritis of the Shoulder index). RESULTS: Compared with preoperative values, both groups achieved minimal clinically important differences in range of motion and patient-reported outcomes at the final follow-up. We found no significant differences between groups in any of these measures at the final follow-up. Rates of revision (inlay, 3.8% vs. onlay, 1.4%), scapular notching (inlay, 5.1% vs. onlay, 7.0%), acromial stress fracture (inlay, 0% vs. onlay, 2.8%), and tuberosity resorption (inlay, 25% vs. onlay, 27%) were not significantly different between groups (all, P > .05). CONCLUSION: For patients with glenohumeral osteoarthritis with glenoid bone loss and an intact rotator cuff who underwent RSA using a lateralized glenosphere prosthesis with a 135° NSA, there were no significant differences between the inlay and onlay groups for range of motion, patient-reported outcomes, or complication rates. These findings are limited to this off-label indication for RSA.

Introduction: The COVID-19 pandemic has highlighted significant racial and age-related health disparities. In response to pandemic-related restrictions, orthopedic surgery departments have expanded telemedicine use. We analyzed data from a tertiary care institute during the pandemic to understand potential racial and age-based disparities in access to care and telemedicine utilization. Materials and Methods: Data on patient race and age, and numbers of telemedicine visits, in-person office visits, and types of telemedicine were extracted for time periods during and preceding the pandemic. We calculated odds ratios for visit occurrence and type across race and age groups. Results: Patients ages 27-54 were 1.3 (95% confidence interval [CI] 1.1-1.4, p < 0.01) and 1.2 (95% CI 1.0-1.3, p < 0.05) times more likely to be seen than patients <27 during the pandemic, versus the 2019 and 2020 controls. Patients 54-82 were 1.3 (95% CI 1.1-1.5, p < 0.001) times more likely to be seen than patients <27 during the pandemic versus the 2019 control. Patients 27-54, 54-82, and 82+, respectively, were 3.3 (95% CI 2.6-4.2, p < 1e-20), 3.5 (95% CI 2.8-4.4, p < 1e-24), and 1.9 (95% CI 1.1-3.4, p < 0.05) times more likely to be seen by telemedicine than patients <27. Among pandemic telemedicine appointments, Black patients were 1.5 (95% CI 1.2-1.9, p < 1e-3) times more likely to be seen by audio-only telemedicine than White patients, as compared with video telemedicine. Conclusions: Telemedicine access barriers must be reduced to ensure that disparities during the pandemic do not persist.

BACKGROUND: With an aim of improving prosthesis survivorship of unicompartmental knee arthroplasty (UKA), use of computer-assisted technologies (CATs) such as robotics, has been on the rise to reduce intraoperative errors in surgical technique. In light of recent influx of CATs in the UKA, a review of these innovations will help providers to understand their clinical utility. METHOD: A systematic literature search was performed following Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. RESULTS: Among 19 studies comparing robot-assisted UKA with conventional UKA, only 32% were randomized control trials, 47% reported minimum mean follow-up of 2 years, and 21% evaluated prosthesis survival. Similar results were obtained for navigation-assisted UKA and UKA performed with patient-specific instrumentation. CONCLUSION: While CATs seem to reduce the surgical errors in UKA, the evidence on the efficacy of any of the studied CATs to improve survivorship remains limited and there are issues related to cost-effectiveness, learning curve, and increase in operating time.
