Purpose To compare lower extremity soft tissue injury and revision surgery rates for patients with anorexia nervosa (AN) and bulimia nervosa (BN) compared with matched controls. Methods This retrospective cohort study used a deidentified claims database. Patients were included if they carried an International Classification of Diseases code for AN or BN. Respective matched cohorts for AN and BN were created using propensity score matching. Primary and revision surgeries for anterior cruciate ligament (ACL) reconstruction, posterior cruciate ligament reconstruction, knee collateral ligament reconstruction, meniscus repair or meniscectomy, and any ankle ligament reconstruction were identified by their CPT codes. Patients over the age of 40 and without a minimum 2‐year follow‐up after primary surgery were excluded. Differences in prevalence and revision rates were analyzed. Results A total of 56,146 patients with AN and 42,630 patients with BN were included in this study with equal numbers in respective matched cohorts. Patients with BN showed an increased risk of ACL injury (relative risk = 1.32, P = .019), medial collateral ligament injury (1.17, 0.04), calcaneofibular sprain (1.92, <0.001), deltoid sprain (1.41, 0.004), and unspecified ankle sprain (1.44, <0.001). Patients with AN showed an increased risk for calcaneofibular sprain (1.25, 0.007), deltoid sprain (1.28, 0.015), and unspecified ankle sprain (1.17, <0.001). Patients with BN were more likely to have revision ACL repair (1.89, 0.02), partial meniscus revision (3.44, <0.001) and any meniscus revision (4.74, <0.001) while patients with AN were more likely to have an ACL revision (2.81, <0.001), partial meniscus (4.37, <0.001), and any meniscus (4.52, <0.001). Conclusions In this study, patients with AN and BN had a significantly increased risk for various knee and ankle injuries and revision surgeries compared with matched controls. Additionally, patients with AN and BN who sustained these injuries were more likely to undergo a revision surgical procedure within the first 5 years of the primary procedure. Level of Evidence Level III, retrospective comparative study.

Background: The aim of this study was to evaluate the prevalence and perceived efficacy of cannabidiol (CBD) products in patients presenting to an orthopedic hand and upper extremity clinic. Materials and Methods: New patients seen for an initial surgical consultation between July and December 2022 were surveyed regarding CBD use, pain, and function. Pain was measured with the Numeric Pain Rating Scale (NPRS, 0–10) and function with the Single Assessment Numeric Evaluation (SANE, 0–100). Demographic and clinical factors were collected via chart review. Results: A total of 918 patients completed the survey (53% female; mean age 63 years, range 18–97). Joints involved included elbows (106), wrists (335), and hands/fingers (667). Common diagnoses included arthritis (199), tendinopathy (273), and nerve-related conditions (160). Overall, 15% (135/918) reported prior CBD use, and 39% (53/135) perceived pain relief. CBD users were more likely to be female (65% vs 51%; P =0.003), to present with wrist pathology (44% vs 35%; P =0.038), and to have arthritis (36% vs 19%; P <0.001). Compared to non-users, CBD users reported higher pain scores (mean NPRS 6.2 vs 5.1; P <0.001) and lower contralateral function (mean SANE 77.3 vs 87.4; P <0.001). Conclusions In this cohort, CBD use was uncommon, and only a minority of users reported subjective benefit. CBD users tended to report higher pain and worse function, particularly in the setting of wrist arthritis. CBD products did not appear to provide measurable objective improvement in pain or function. Further studies are needed to clarify optimal dosing, administration, and potential role in upper extremity care.

Background: There has been minimal literature evaluating how a prior myocardial infraction (MI) influences outcomes after total knee arthroplasty (TKA). Thus, the purpose of this study was to evaluate how the timing, type, and treatment of MI prior to TKA affect postoperative cardiac complications, general medical complications, and surgical complications. Methods: A retrospective comparative study was conducted using a large insurance database. Patients undergoing primary TKA for osteoarthritis were included. Patients who had experienced MI within 2 years before TKA were identified and were matched 1:4 with patients who had not had such an MI on the basis of demographic variables and comorbidities. Patients who had a prior MI were stratified into 4 groups based on the timing of the MI: 0 to <6 months, 6 to <12 months, 12 to <18 months, and 18 to 24 months before TKA. The rates of postoperative cardiac, general medical, and surgical complications were compared between groups. Subanalyses on the prior MI type, treatment, and location were performed. Results: Prior MI was associated with increased risks of postoperative MI (odds ratio [OR], 3.97 [95% confidence interval (CI), 3.20 to 4.93]), heart failure (OR, 1.45 [95% CI, 1.24 to 1.75]), and 90-day mortality (OR, 2.15 [95% CI, 1.41 to 3.28]). The risk of postoperative MI was highest for those with MI within 6 months before TKA (OR, 6.86 [95% CI, 5.34 to 8.82]). Type-1 MI, ST-elevation MI (STEMI), non-ST-elevation MI (NSTEMI), and anterior and inferior MIs were linked to elevated postoperative MI and/or mortality risks, with timing closer to surgery further amplifying the risk. Percutaneous coronary intervention within 6 months before TKA also increased postoperative risks. Type-2 MI within 6 months before TKA was associated with an increased risk of periprosthetic joint infection compared with controls (OR, 4.23 [95% CI, 1.67 to 10.67]). Conclusions: Patients who had a prior MI, particularly within 6 months before TKA, had significantly elevated risks of postoperative MI, heart failure, and mortality. Outcomes varied by MI type, treatment, and location, with type-1 MIs and STEMIs increasing the postoperative mortality risk. Level of Evidence: Prognostic Level III .

Background: Supracondylar humerus fractures (SCH) are the most common type of elbow fracture in children, with many cases requiring surgery. Treatment of postoperative pain for SCH has high variability, but can often be treated effectively with minimal or no opioids. Furthermore, there is significant morbidity related to pediatric opioid consumption. The goal of this study was to characterize prescription patterns in the United States following closed reduction and percutaneous pinning (CRPP) of SCH. Methods: All patients aged 10 or younger years who underwent CRPP of SCH from January 2010 to December 2021 were identified in the PearlDiver Mariner Claims Database. The primary outcome was postoperative pain medication prescriptions in the 30 days following SCH CRPP. Patient demographics, prescription duration, and morphine milligram equivalents (MME) were analyzed. Multivariable-log-binomial mixed regression models were constructed to assess factors associated with increased opioid prescription. Results: In total, 43,611 SCH CRPP cases in patients aged 10 or younger were identified from 2010 to 2021. Throughout the study period, 48.6% of patients (21,191/43,611) received and filled a narcotic pain prescription. The percentage of patients receiving opioid medication decreased from 54.7% in 2010 to 27.4% in 2021. Opioid prescriptions totaled a mean of 6.1±2.1 days of narcotics with a mean of 79.2 MME prescribed per patient. Increased patient age, increased Elixhauser comorbidity index, and Medicaid insurance were all associated with increased opioid prescription (P<0.001). Living in the Northeast, increased family income, and commercial insurance were associated with decreased opioid prescriptions (P<0.001). Conclusions: Nearly half of the patients over the past decade treated with CRPP for SCH received a narcotic prescription. However, there has been a steady decline in the proportion of patients being prescribed opioids, with only 27.4% receiving opioids in 2021. Further, patients with increased comorbidities or those insured by Medicaid with lower mean family income may be at risk for increased opioid prescription. While efforts have been made to reduce opioid overprescribing, there continues to be room for further reduction in opioid utilization after CRPP for SCH moving forward.

Background: Although it is well established that the type of organism can be a risk factor for failure in patients with periprosthetic joint infection (PJI), no study to date has examined the impact of the number of positive cultures on treatment outcomes in patients undergoing 2-stage exchange. The purpose of this multicenter study was to determine the prognostic utility of multiple positive cultures at resection as a predictor of failure following reimplantation. Methods: This retrospective multicenter study identified 437 patients with chronic knee PJI who had undergone 2-stage exchange arthroplasty with a minimum of 1 year of follow-up following reimplantation. PJI was defined with use of the 2013 Musculoskeletal Infection Society (MSIS) criteria. Patients with culture-negative PJI were excluded (n = 138). Treatment failure was defined as either any reoperation for infection or PJI-related mortality. Multivariable regression controlling for risk factors for failure after a 2-stage arthroplasty was performed to determine whether ≥2 positive intraoperative cultures at resection can predict outcomes following reimplantation when compared with a single positive culture. Results: Two hundred and ninety-nine patients were included. At a mean follow-up of 6.2 ± 2.6 years, 48 patients (16.1%) experienced failure. Patients who had a failure were more likely to have had a longer interstage interval (p = 0.038) and were also more likely to have had ≥2 positive cultures at the time of resection arthroplasty (95.8% versus 75.3%; p = 0.001). On regression analysis, ≥2 positive cultures at resection was the only variable that was identified as a risk factor for failure following reimplantation in both the univariate (odds ratio [OR], 7.55 [95% CI, 2.24 to 47.0]; p = 0.006) and multivariable models (OR, 8.12 [95% CI, 2.31 to 51.9]; p = 0.005). Conclusions: This is the first study to examine the impact of the number of positive cultures on outcomes in patients with PJI. We found that the presence of ≥2 positive cultures at resection was an indicator of a poor prognosis and resulted in a greater than eightfold increase in the risk of treatment failure in patients undergoing a 2-stage exchange.

Purpose To describe injury epidemiology in U.S. adolescent tennis players between 2014 and 2018 via the High School Reporting Information Online (HS RIO) database. Methods The HS RIO database was queried for injury data on high school tennis players as reported by athletic trainers between 2014 and 2018. Injuries were analyzed according to athlete demographics, injury type, location, and context. Variables of interest between male and female athletes were compared using Pearson χ 2 test or Fisher exact test. Results In total, 176 injuries in high school tennis players between 2014 and 2018 were identified in the HS RIO database. Overall, 25.6% (45/176) occurred in the ankle, 12.5% (22/176) in the knee, and 9.7% (17/176) in the wrist. The most common types of injuries were ligament sprains and muscle strains at 35.2% (62/176) and 17.6% (31/176) of injuries, respectively. Although most injuries were unrelated to contact, such as overuse and heat exertion or stroke, 28.7% (47/176) of injuries were the result of rotation around a planted foot/inversion of the foot. We found no difference in injury patterns between male and female high school tennis athletes. Conclusions We found no difference in injury patterns between male and female U.S. high school tennis athletes. The ankles, knees, and wrists were the most commonly injured areas in this population. The most common types of injuries were ligament sprains and muscle strains. Although many injuries were new, athletes rarely required surgery and returned to play. Finally, we found no difference in injury patterns between male and female high school tennis athletes. Clinical Relevance The epidemiology of injuries among high school tennis players is poorly understood. The information from this study will help us to understand these injuries and how we may be able to better prevent them.

Background: While previously used in other specialties, the preference signaling program (PSP) was implemented in the 2022 to 2023 orthopaedic surgery residency application process for the first time. The PSP allowed for 30 signaling tokens to be sent by applicants to programs of their choice to indicate particular interest in a program. It remains unknown how the PSP affects applicants and programs in the orthopaedic surgery residency match. Thus, this study's purpose was to assess the utility of preference signaling within the orthopaedic surgery residency application process in its inaugural year of use. Methods: An anonymous electronic survey was emailed to all orthopaedic surgery residency applicants who applied to the authors' institution during the 2022 to 2023 application cycle. The survey was sent after match lists were submitted and closed before the release of match results. The survey collected information regarding applicant demographics, preference signaling habits, and attitude toward preference signaling. Results: The survey was completed by 101 applicants. Applicants applied to a mean of 90 programs (range: 10-197) and received an average of 12 interview invitations (range: 0-39). Applicants almost uniformly used all 30 signals, with nearly two-thirds signaling their home programs (65%, 49/76), and nearly all applicants sending signals to programs at which they performed away rotations (95.7%, 88/92). Applicants received a mean of 9 invitations from programs they signaled, compared with 2 invitations from programs they did not signal. Applicants were significantly more likely to receive an interview invite at a program they signaled than one they did not (p < 0.01). Overall, 57% of applicants (57/101) found the PSP to be helpful, whereas 28% (28/101) found it to be unhelpful, and 16% (16/101) had a neutral opinion. Conclusions: This study reports that the PSP in the 2022 to 2023 orthopaedic surgery match was an effective method of expressing interest in a program because applicants were significantly more likely to receive interview invites to signaled programs. More than half of respondents felt PSP to be helpful; however, the effect on application numbers is still unclear. Level of Evidence: III

AbstractIntroductionMinimum clinically important differences (MCIDs) are critical to understanding changes in patient-reported outcome measure (PROM) scores after total joint arthroplasty (TJA). The usage and adoption of MCIDs not been well-studied. This study was performed to IDENTIFY trends in PROM and MCID use after TJA over the past decade.MethodsAll articles published in the calendar years of 2010 and 2020 in CORR, JBJS, and the Journal of Arthroplasty were reviewed. Articles relating to clinical outcomes in primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) were included. For each article, all reported PROMs and (if present) accompanying MCIDs were recorded. The use of PROMs and MCIDs were compared between articles published in 2010 and 2020.ResultsOverall, 263 articles from 2010 and 546 articles from 2020 were included. The total number of articles reporting any PROM after THA and TKA increased from 131 in 2010 to 194 in 2020, but the proportion of articles reporting PROMs decreased from 49.8% (131/263) to 35.5% (194/546). Both the total number and proportion of articles reporting MCIDs increased from 2.3% (3/131) in 2010 to 16.5% (32/194) in 2020. These trends persisted when analyzing THA and TKA articles individually.ConclusionsBoth the absolute number and proportion of articles reporting MCIDs in conjunction with PROMs after TJA has increased in the past decade but remains low. We recommend that journal editors and meeting organizers encourage the inclusion of MCID information in all reports on clinical outcomes after joint replacement.

Background: Carpal tunnel release (CTR) surgery is the most common surgery billed to Medicare by hand surgeons. As such, the purpose of this study was to evaluate trends for CTR surgeries billed to Medicare from 2000 to 2020. Methods: The publicly available Medicare Part B National Summary File from 2000 to 2020 was queried. For both open carpal tunnel release (OCTR) and endoscopic carpal tunnel release (ECTR), the number of procedures and total Medicare reimbursement were extracted. For year 2020, the specialty of the performing surgeon was recorded. Descriptive statistics were reported. Results: A total of 3 429 471 CTR surgeries were performed in the Medicare population from 2000 to 2020. For these procedures, Medicare paid surgeons over $1.23 billion. During this period, there was a 101.8% increase in annual CTR procedures (91 130 in 2000, 183 911 in 2020). Further, annual volume of ECTR increased by 456.2%, and accounted for an increasing percentage of total CTR procedures (9.1% in 2012, 25.2% in 2020). The average adjusted Medicare reimbursement per procedure decreased by 1.5% for OCTR, and decreased by 11.6% for ECTR. In 2020, orthopedic surgeons performed 85.1% of CTR procedures. Conclusions: The volume of CTR surgeries among the Medicare population has increased from 2000 to 2020, and ECTR is accounting for a growing proportion of surgeries. When adjusted for inflation, average reimbursement has decreased, with a greater decrease among ECTR. Orthopedic surgeons perform most of such surgeries. These trends are important to assure adequate resource allocation as treating carpal tunnel becomes more common among the aging Medicare population.
