RESUMEN
OBJECTIVES: To investigate the impact of demographic and socioeconomic factors on the management of isolated meniscus tears in young patients and to identify trends in surgical management of meniscus tears based on surgeon volume. METHODS: Data from a large healthcare system on patients aged 14-44 years who underwent isolated meniscus surgery between 2016 and 2022 were analysed. Patient demographics, socioeconomic factors and surgeon volume were recorded. Patient age was categorised as 14-29 years and 30-44 years old. Area Deprivation Index (ADI), a measure of neighbourhood disadvantage with increased ADI corresponding to more disadvantage, was grouped as <25th, 25-75th and >75th percentile. Multivariate comparisons were made between procedure groups while univariate comparisons were made between surgeon groups. RESULTS: The study included 1552 patients treated by 84 orthopaedic surgeons. Older age and higher ADI were associated with higher odds of undergoing meniscectomy. Patients of older age and with non-private insurance were more likely to undergo treatment by a lower-volume knee surgeon. Apart from the year 2022, higher-volume knee surgeons performed significantly higher rates of meniscus repair compared with lower-volume knee surgeons. When controlling for surgeon volume, higher ADI remained a significant predictor of undergoing meniscectomy over meniscus repair. CONCLUSION: Significant associations exist between patient factors and surgical choices for isolated meniscus tears in younger patients. Patients of older age and with increased neighbourhood disadvantage were more likely to undergo meniscectomy versus meniscus repair. While higher-volume knee surgeons favoured meniscus repair, a growing trend of meniscus repair rates was observed among lower-volume knee surgeons. LEVEL OF EVIDENCE: Retrospective cohort study, level III.

PURPOSE: To investigate the potential use of large language models (LLMs) in orthopaedics by presenting queries pertinent to anterior cruciate ligament (ACL) surgery to generative pre-trained transformer (ChatGPT, specifically using its GPT-4 model of March 14th 2023). Additionally, this study aimed to evaluate the depth of the LLM's knowledge and investigate its adaptability to different user groups. It was hypothesized that the ChatGPT would be able to adapt to different target groups due to its strong language understanding and processing capabilities. METHODS: ChatGPT was presented with 20 questions and response was requested for two distinct target audiences: patients and non-orthopaedic medical doctors. Two board-certified orthopaedic sports medicine surgeons and two expert orthopaedic sports medicine surgeons independently evaluated the responses generated by ChatGPT. Mean correctness, completeness, and adaptability to the target audiences (patients and non-orthopaedic medical doctors) were determined. A three-point response scale facilitated nuanced assessment. RESULTS: ChatGPT exhibited fair accuracy, with average correctness scores of 1.69 and 1.66 (on a scale from 0, incorrect, 1, partially correct, to 2, correct) for patients and medical doctors, respectively. Three of the 20 questions (15.0%) were deemed incorrect by any of the four orthopaedic sports medicine surgeon assessors. Moreover, overall completeness was calculated to be 1.51 and 1.64 for patients and medical doctors, respectively, while overall adaptiveness was determined to be 1.75 and 1.73 for patients and doctors, respectively. CONCLUSION: Overall, ChatGPT was successful in generating correct responses in approximately 65% of the cases related to ACL surgery. The findings of this study imply that LLMs offer potential as a supplementary tool for acquiring orthopaedic knowledge. However, although ChatGPT can provide guidance and effectively adapt to diverse target audiences, it cannot supplant the expertise of orthopaedic sports medicine surgeons in diagnostic and treatment planning endeavours due to its limited understanding of orthopaedic domains and its potential for erroneous responses.

PURPOSE: Variations in femoral and tibial bony morphology have been associated with higher clinical grading and increased quantitative tibial translation, but not tibial acceleration, during the pivot shift test following anterior cruciate ligament (ACL) injury. The purpose of this study was to determine the impact of femoral and tibial bony morphology, including a measurement influenced by both parameters (the Lateral Tibiofemoral Articular Distance (LTAD)), on the degree of quantitative tibial acceleration during the pivot shift test and rates of future ACL injury. METHODS: All patients who underwent primary ACL reconstruction from 2014 to 2019 by a senior orthopedic surgeon with available quantitative tibial acceleration data were retrospectively reviewed. All patients underwent a pivot shift examination under anesthesia with a triaxial accelerometer. Measurements of femoral and tibial bony morphology were performed by two fellowship-trained orthopedic surgeons using preoperative magnetic resonance imaging and lateral radiographs. RESULTS: Fifty-one patients were included at a mean follow-up of 4.4 years. The mean quantitative tibial acceleration during the pivot shift was 13.8 m/s2 (range: 4.9-52.0 m/s2). A larger Posterior Condylar Offset Ratio (r = 0.30, p = 0.045), smaller medial-to-lateral width of the medial tibial plateau (r = - 0.29, p = 0.041), lateral tibial plateau (r = - 0.28, p = 0.042), and lateral femoral condyle (r = - 0.29, p = 0.037), and a decreased LTAD (r = - 0.53, p < 0.001) significantly correlated with increased tibial acceleration during the pivot shift. Linear regression analysis demonstrated an increase in tibial acceleration of 1.24 m/s2 for every 1 mm decrease in LTAD. Nine patients (17.6%) sustained ipsilateral graft rupture and 10 patients (19.6%) sustained contralateral ACL rupture. No morphologic measurements were associated with rates of future ACL injury. CONCLUSION: Increased convexity and smaller bony morphology of the lateral femur and tibia were significantly associated with increased tibial acceleration during the pivot shift. Additionally, a measurement, termed the LTAD, was found to have the strongest association with increased tibial acceleration. Based on the results of this study, surgeons can utilize these measurements to preoperatively identify patients at risk of increased rotatory knee instability. LEVEL OF EVIDENCE: Level IV.

PURPOSE: To evaluate the biomechanical profile of onlay distal biceps repair with an intramedullary unicortical button versus all-suture anchors under cyclic loading and maximal load to failure. METHODS: Twenty paired fresh-frozen human cadaveric elbows were randomized to onlay distal biceps repair with either a single intramedullary button or with two 1.35-mm all-suture anchors. A 1.3-mm high tensile strength tape was used in a Krackow stitch to suture the tendons in both groups. Specimens and repair constructs were loaded for 3,000 cycles and then loaded to failure. Maximum load to failure, mode of failure, and construct elongation were recorded. RESULTS: Mean (± standard deviation) maximum load to failure for the unicortical intramedullary button and all-suture anchor repairs were 503.23 ± 141.77 N and 537.33 ± 262.13 N (P = .696), respectively. Mean maximum displacement after 3,000 cycles (± standard deviation) was 4.17 ± 2.05 mm in the button group and 2.06 ± 1.05 mm in the suture anchor group (P = .014). Mode of failure in the button group was suture tape rupture in 7 specimens, failure at the tendon-suture interface in 2 specimens, and button pullout in 1 specimen. Anchor pullout was the mode of failure in all suture anchor specimens. There were no tendon ruptures or radial tuberosity fractures in either group. CONCLUSIONS: This study demonstrates that onlay distal biceps repair with 2 all-suture anchors has similar maximum strength to repair with an intramedullary button and that both are viable options for fixation. CLINICAL RELEVANCE: All-suture anchors and unicortical intramedullary button have similar maximum strength at time zero. Both constructs provide suitable fixation for onlay distal biceps repair.

BACKGROUND: Total joint arthroplasties aim to improve quality of life from joint-related pain. Jehovah's Witnesses refuse blood products due to their religious beliefs. Surgeons may be reluctant to perform arthroplasty procedures on these patients for fear of uncontrolled bleeding. However, we hypothesize that through preoperative optimization, arthroplasty can be performed safely. METHODS: We retrospectively reviewed 184 total joint arthroplasties in Jehovah's Witnesses between 2011 and 2019. Each patient was enrolled in the institutions' Bloodless Medicine program. Hemoglobin levels were recorded through standard laboratory testing while in the hospital. Primary outcomes were changes in preoperative and postoperative hemoglobin measures, short-term outcomes measures, and complications. RESULTS: A total of 103 total knee arthroplasties (8 revisions) and 81 total hip arthroplasties (5 revisions) were performed. Hemoglobin drift was 2.5 ± 1.0 for primary TKA and 2.6 ± 1.3 for primary THA (p = 0.570). Hemoglobin drift was 1.9 ± 0.9 for revision TKA and 1.9 ± 0.2 for revision THA (p = 0.990). Only 2.7% of patients met the transfusion requirement of 7 g/dL. The major complication rate for the cohort was 1.6% systemic and 4.9% local, respectively, with no mortalities. The overall readmission rate was 2.7%. CONCLUSION: To our knowledge, this is the largest reported sample of Jehovah's Witness patients undergoing total joint arthroplasty. Postoperative hemoglobin values did not prompt additional intervention in the overwhelming majority of patients, and complication rates were acceptable. Our data suggest that primary arthroplasty is safe in the Jehovah's Witness population. Additionally, we show preliminary evidence that revision arthroplasty is safe in Jehovah's Witness patients.

Chronic plantar fasciitis is a common cause of foot pain, with conservative treatment providing relief for most patients. However, because of the common occurrence of this pathology, this leaves many patients dissatisfied. The purpose of the present study was to determine the effectiveness of extracorporeal shock wave therapy (ESWT) to treat chronic plantar fasciitis (PF) in a largely active duty population. A review of 82 patients (115 heels) who had undergone ESWT for chronic PF was performed. Outcome data were obtained by patient telephone interviews. All ESWT was conducted at 24 kV for 2000 shocks. Of the 82 patients (115 heels), 76 (93%; 111 heels) agreed to participate. Their mean age was 42 ± 10 years, with 41 males (54%) and 35 females (46%). The mean follow-up period was 42 ± 22 months. Of the patients, 73.6% were active duty military personnel. The mean preoperative pain score of 7.8 ± 2 had improved to 2.5 ± 2 at the last follow-up visit (p <.0001). Active duty patients reported a mean improvement in pain of 4.8 ± 3 compared with 6.8 ± 3 in non-active duty patients (p = .005). Of the 76 patients, 75 (98%) underwent 1 ESWT session, and 1 (2%) requiring 2 sessions. Overall, 74% of patients rated the outcome of their procedure as either good or excellent, with 87% stating that ESWT was successful. Ten patients (18%) left the military because of continued foot pain, with 76% able to return to running. For patients with chronic PF, these results support the use of ESWT to relieve pain in >85% of patients, with a preponderance for better pain relief in patients who are not active duty military personnel.

Coronal and sagittal plane knee malalignments have been shown to increase the forces on anterior cruciate ligament (ACL) grafts after ACL reconstruction (ACLR). Studies have shown the benefit of high tibial osteotomy to address coronal and sagittal imbalance in revision ACLR. The purpose of this article is to further describe the use of osteotomy by reviewing preoperative planning, indications, techniques, and outcomes of high tibial opening and closing wedge as well as anterior tibial closing wedge osteotomies in the setting of ACLR.

Background: Periprosthetic joint infection of the shoulder (PJI) is a devastating complication with a reported incidence of 1%-15.4% and is often difficult to diagnose with current diagnostic tools including serologic tests and arthrocentesis. This systematic review evaluates the reliability and validity of arthroscopic biopsy in the current literature for the diagnosis of shoulder PJI. Methods: MEDLINE, Scopus, Web of Sciences, Google Scholar, and Cochrane databases were queried electronically from inception to June 2022 for publications reporting diagnostic accuracy of shoulder arthroscopic biopsy for detecting infection after anatomic total shoulder arthroplasty, shoulder hemiarthroplasty, or reverse total shoulder arthroplasty. This systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: After exclusion, our meta-analysis consisted of 7 articles with a total of 112 patients. The estimated pooled sensitivity and specificity of arthroscopic biopsy for confirmation of shoulder periprosthetic infection were 0.87 (95% confidence interval [CI]: 0.73-0.95) and 0.79 (95% CI: 0.67-0.88), respectively. The pooled positive likelihood ratio and negative likelihood ratio were 4.15 (95% CI: 2.57, 6.70) and 0.17 (95% CI: 0.08, 0.36), respectively. The aggregate positive predictive value was 73.58% (95% CI: 63.29%-81.82%), and aggregate negative predictive value was 89.83% (95% CI: 80.59%-94.95%). The diagnostic odds ratio of arthroscopic biopsy was 19.92 (95% CI: 4.96-79.99). Conclusion: Arthroscopic biopsy in patients suspected of shoulder PJI has good diagnostic accuracy, with high sensitivity and specificity. Given the various biopsy protocols (such as devices, numbers, locations, etc.), further prospective studies are necessary to define the future role of arthroscopic biopsy in diagnosis and treatment.
RESUMEN
PURPOSE OF REVIEW: The addition of lateral extra-articular tenodesis (LET) to anterior cruciate ligament (ACL) reconstruction (ACLR) has become increasingly popular to address residual rotatory knee instability. The purpose of this article is to review the anatomy and biomechanics of the anterolateral complex (ALC) of the knee, outline different LET techniques, and provide biomechanical and clinical evidence for its use as an augmentation procedure with ACLR. RECENT FINDINGS: Rotatory knee instability has been identified as a common contributor to ACL rupture in both the primary and revision settings. Several biomechanical studies have shown that LET reduces strain on the ACL by decreasing excess tibial translation and rotation. Additionally, in vivo studies have demonstrated restoration of side-to-side differences in anterior-posterior knee translation, higher rates of return to play, and overall increased patient satisfaction following combined ACLR and LET. As a result, various LET techniques have been developed to help offload the ACL graft and lateral compartment of the knee. However, conclusions are limited by a lack of concrete indications and contraindications for use of LET in the clinical setting. Recent studies have shown that rotatory knee instability contributes to native ACL and ACL graft rupture and LET may provide further stability to reduce rates of failure. Further investigation is needed to establish concrete indications and contraindications to determine which patients would most benefit from added stability of the ALC.
RESUMEN
Glenohumeral bone loss is frequently observed in cases of recurrent anterior and posterior shoulder instability and represents a risk factor for failure of nonoperative treatment. Patients with suspected glenoid or humeral bone loss in the setting of recurrent instability should be evaluated with a thorough history and physical examination, as well as advanced imaging including computed tomography (CT) and/or magnetic resonance imaging (MRI). In cases of both anterior and posterior instability, the magnitude and location of bone loss should be determined, as well as the relationship between the glenoid track (GT) and any humeral defects. While the degree and pattern of osseous deficiency help guide treatment, patient-specific risk factors for recurrent instability must also be considered when determining patient management. Treatment options for subcritical anterior bone loss include labral repair and capsular plication, while more severe deficiency should prompt consideration of bony augmentation including coracoid transfer or free bone block procedures. Concomitant humeral lesions are treated according to the degree of engagement with the glenoid rim and may be addressed with soft tissue remplissage or bony augmentation procedures. While critical and subcritical thresholds of glenoid bone loss guide the management of anterior instability, such thresholds are less defined in the setting of posterior instability. Furthermore, current treatment algorithms are limited by a lack of long-term comparative studies. Future high-quality studies as well as possible modifications in indications and surgical technique are required to elucidate the optimal treatment of anterior, posterior, and bipolar glenohumeral bone loss in the setting of recurrent shoulder instability.
RESUMEN
PURPOSE: The purpose of this study was to assess the effect of surgeon anterior cruciate ligament reconstruction (ACLR) volume on rates of ACLR with concomitant meniscus repair versus meniscectomy and subsequent meniscus surgeries. METHODS: A retrospective review was conducted from a database of all ACLR performed between 2015 and 2020 at a large integrated health care system. Surgeon volume was categorized as < 35 ACLR per year (low-volume), and ≥ 35 ACLR per year (high-volume). Rates of concomitant meniscus repair and meniscectomy were compared between low-volume and high-volume surgeons. Subgroup analyses compared the rates of subsequent meniscus surgery and procedure time based on surgeon volume and meniscus procedure type. RESULTS: A total of 3,911 patients undergoing ACLR were included. High-volume surgeons performed concomitant meniscus repair statistically significantly more often than low-volume surgeons (32.0% vs 10.7%, p < 0.001). Binary logistic regression indicated 4.15 times higher odds of meniscus repair among high-volume surgeons. Subsequent meniscus surgery occurred more commonly following ACLR with meniscus repair among low-volume surgeons (6.7% vs 3.4%, p = 0.047), but not high-volume surgeons (7.0% vs 4.3%, p = 0.079). Low-volume surgeons also had longer procedure times for concomitant meniscus repair (129.9 vs 118.3 min, p = 0.003) and meniscectomy (100.6 vs 95.9 min, p = 0.003). CONCLUSIONS: Data from this study shows that surgeons with lower volume of ACLR select meniscus resection statistically significantly more often than higher-volume surgeons. However, an abundance of literature is available to show that meniscus loss negatively affects the development of post-traumatic osteoarthritis in patients Therefore, as demonstrated in this study by high-volume surgeons, the meniscus should be repaired and protected whenever possible. LEVEL OF EVIDENCE: III.
RESUMEN
Purpose: To determine whether surgeon volume affects revision rate following primary anterior cruciate ligament reconstruction (ACLR) with allograft and to determine whether surgeon volume impacts allograft tissue type used. Methods: All patients aged 14 years or older who underwent primary allograft ACLR at a large hospital system between January 2015 to December 2019 with minimum 2-year follow-up were included. Patients with double-bundle ACLR, multiligament reconstruction, and absent allograft type data were excluded. Surgeon volume was categorized as 35 or more ACLR/year for high-volume surgeons and less than 35 ACLR/year for low-volume surgeons. Revision was defined as subsequent ipsilateral ACLR. Patient characteristics, operative details, allograft type, and revision ACLR rates were retrospectively collected. Revision rate and allograft type were analyzed based on surgeon volume. Results: A total of 457 primary allograft ACLR cases (mean age: 38.8 ± 12.3 years) were included. Low-volume surgeons experienced greater revision rates (10% vs 5%, P = .04) and used allograft in a younger population (37.6 vs 40.0 years old, P = .03) than high-volume surgeons. Subgroup analysis of the total cohort identified a significantly increased failure rate in patients <25 years old compared with ≥25 years old (30% vs 4%, P < .001). Allograft type selection varied significantly between surgeon volume groups, with low-volume surgeons using more bone-patellar tendon-bone (P < .001) and less semitendinosus allograft (P = .01) than high-volume surgeons. No differences in revision rate were observed based on allograft type (P = .71). Conclusions: There was a greater revision rate following primary allograft ACLR among low-volume surgeons compared with high-volume surgeons. Low-volume surgeons also used allograft in a younger population than did high-volume surgeons. Level of Evidence: Level III, retrospective comparative prognostic trial.
RESUMEN
INTRODUCTION: The gender disparity in orthopaedic surgery has been recognized for many years. Because research affects promotions, this study investigates trends in female authorship in three journals over the past 25 years for both first and senior authors. METHODS: All articles from Journal of Bone and Joint Surgery, Journal of the American Academy of Orthopaedic Surgeons, and Clinical Orthopaedics and Related Research from 1995 to 2020 in 5-year intervals were downloaded, and the data for first and senior authors were extracted. The sex of the first and senior authors was determined using the validated Genderize algorithm. The demographics of the first and senior author cohorts were analyzed using chi square tests. The trends in female authorship controlling for year and journal were assessed with logistic regression models. RESULTS: Within the studied journals, 5,636 individuals were identified as first authors and 4,572 as senior authors. Sex was determined for 82.59% of the authors. Female first authorship increased significantly from 1995 to 2020 (6.70% to 15.37%, P < 0.001). Similarly, female senior authorship increased significantly from 1995 to 2020 (8.22% to 13.65%, P < 0.001). Overall, there was no significant difference in gender composition of authors between journals (P = 0.700 first author and P = 0.098 senior author). Women were much more likely to publish as first or senior author in later years, regardless of the journal (P < 0.001 first author and P < 0.001 senior author). DISCUSSION: Female authorship in prominent orthopaedic journals has increased markedly from 1995 to 2020 with interjournal differences in senior author gender disparity. Although female orthopaedic surgeons publish at rates equal to or greater than their representation in the specialty, additional research is needed into the persistence of gender disparities in orthopaedics.

BACKGROUND: Bone marrow aspirate concentrate (BMAC) has emerged as a therapeutic option for symptomatic knee osteoarthritis (OA). PURPOSE: To systematically review the literature to evaluate the efficacy of isolated BMAC injection in the treatment of OA of the knee joint. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic review was performed by searching the PubMed, Embase, and Cochrane Library databases up to July 2020 to identify human studies that assessed the clinical outcomes of isolated BMAC injection for the treatment of knee OA. The electronic search strategy used was "bone marrow aspirate concentrate knee osteoarthritis." RESULTS: Eight studies met the inclusion criteria, including a total of 299 knees with a mean follow-up of 12.9 months (range, 6-30 months). Of all patient-reported outcomes assessed across studies, 34 of 36 (94.4%) demonstrated significant improvement from baseline to latest follow-up (P < .05). Five studies evaluating numerical pain scores (visual analog scale and Numeric Rating Scale) reported significant improvements in pain level at final follow-up (P < .01). However, 3 comparative studies evaluating BMAC in relation to other therapeutic injections failed to demonstrate the clinical superiority of BMAC. CONCLUSION: The BMAC injection is effective in improving pain and patient-reported outcomes in patients with knee OA at short- to midterm follow-up. Nevertheless, BMAC has not demonstrated clinical superiority in relation to other biologic therapies commonly used in the treatment of OA, including platelet-rich plasma and microfragmented adipose tissue, or in relation to placebo. The high cost of the BMAC injection in comparison with other biologic and nonoperative treatment modalities may limit its utility despite demonstrable clinical benefit.

Shoulder injury related to vaccine administration (SIRVA) is a rare yet increasingly recognized complication of immunization. Although a medicolegal term rather than a true diagnosis, SIRVA was introduced in 2010 by the Vaccine Injury Compensation Program after an increase in claims filed for vaccine-related shoulder injury. Patients typically present with severe pain and limited range of motion within 48 hours of vaccination and may experience notable functional limitations. Although the underlying pathophysiology is incompletely understood, the existing literature suggests that SIRVA results from the inflammatory response produced when the vaccine is injected into tissues containing a preexisting antibody. Current treatment modalities include physical therapy, corticosteroid injections, and antiinflammatory medications. In some cases, surgery may be required to treat underlying pathology, such as rotator cuff or biceps tendinopathy. Although the available literature indicates modest improvement in patients with SIRVA undergoing treatment, current data are limited to case series. Larger, high-quality studies are needed to determine the natural history and optimal treatment of this increasingly prevalent condition.

BACKGROUND: Multiligamentous knee injuries (MLKIs) are rare, and heterogeneous in presentation and treatment options. Consequently, optimal postoperative rehabilitation of MLKI remains unclear. OBJECTIVE: To summarize the latest evidence for postoperative rehabilitation protocols following multiligamentous knee reconstruction (MLKR). PATIENTS AND METHODS: A multidatabase search was conducted with the aid of a health sciences librarian. Blinded reviewers conducted multiple screenings of studies evaluating postoperative rehabilitation protocols following MLKR. All included studies were then graded based on level of evidence, and data concerning patient demographics and rehabilitation protocols were extracted. RESULTS: MLKR rehabilitation protocols differ widely in terms of weightbearing, bracing, initiation, and types of physical therapy, yet several established protocols were referenced frequently throughout the literature. Such protocols resulted in good outcomes, with patients returning to running in 6 to 12 months and returning to sport in 8 to 12 months. CONCLUSION: The rare nature of MLKI hinders the ability to create a standardized rehabilitation protocol. However, early postoperative physical therapy and range of motion consistently lead to improved outcomes. Randomized studies are needed to determine optimal postoperative rehabilitation following MLKR.

BACKGROUND: Recent evidence suggests that there may be an increased risk of infection for patients undergoing a corticosteroid injection before, during, or after knee arthroscopy. PURPOSE: To systematically review the literature to evaluate the risk of postoperative infection in patients undergoing intra-articular corticosteroid injections (CSI) before, during, or after knee arthroscopy. STUDY DESIGN: Systematic review; Level of evidence, 3. METHODS: A systematic review was performed by searching the PubMed, Cochrane Library, and Embase databases to identify studies that evaluated the rate of postoperative infection in patients undergoing knee arthroscopy who received an intra-articular CSI during the perioperative period. The search phrase used was "knee AND arthroscopy AND injection AND (infection OR revision)." A subanalysis was also performed to analyze infection rates based on the timing of the corticosteroid injection in relation to arthroscopy. RESULTS: Four studies met the inclusion criteria, representing 11,925 patients undergoing knee arthroscopy with an intra-articular CSI administered during the perioperative period (mean follow-up, 5.3 months) and 247,329 patients without a corticosteroid injection during the perioperative period (mean follow-up, 5.9 months). Patients who received an injection experienced a statistically significantly higher rate of postoperative infection (2.2%) when compared with patients who did not receive an injection (1.1%; P < .001). When analyzed by the timing of the injection, patients receiving an injection preoperatively or intraoperatively experienced a statistically significantly higher rate of postoperative infection (3% and 2.6%, respectively) when compared with patients receiving an injection postoperatively (1.4%; P = .001 for both). CONCLUSION: Patients undergoing knee arthroscopy who receive an intra-articular CSI during the perioperative period can be expected to experience significantly higher postoperative infection rates when compared with patients not receiving an injection. Furthermore, patients receiving a corticosteroid injection pre- or intraoperatively may experience significantly higher rates of postoperative infection when compared with patients receiving an injection postoperatively.
RESUMEN
BACKGROUND: Various analgesic modalities have been used to improve postoperative pain in patients undergoing hip arthroscopy. PURPOSE: To systematically review the literature to compare the efficacy of the fascia iliaca block (FIB) with that of other analgesic modalities after hip arthroscopy in terms of postoperative pain scores and analgesic consumption. STUDY DESIGN: Systematic review. METHODS: A systematic review was performed by searching PubMed, the Cochrane Library, and Embase up to April 2020 to identify randomized controlled trials that compared postoperative pain and analgesic consumption in patients after hip arthroscopy with FIB versus other pain control modalities. The search phrase used was "hip arthroscopy fascia iliaca randomized." Patients were evaluated based on postoperative pain scores and total postoperative analgesic consumption. RESULTS: Five studies (3 level 1, 2 level 2) were identified that met inclusion criteria, including 157 patients undergoing hip arthroscopy with FIB (mean age, 38.3 years; 44.6% men) and 159 patients among the following comparison groups: lumbar plexus block (LPB), intra-articular ropivacaine (IAR), local anesthetic infiltration (LAI), saline placebo, and a no-block control group (overall mean age, 36.2 years; 36.5% men). No significant differences in pain scores were reported in the postanesthesia care unit (PACU) between the FIB and LPB (3.4 vs 2.9; P = .054), IAR (7.7 vs 7.9; P = .72), control group (no FIB: 4.1 vs 3.8; P = .76); or saline placebo (difference, -0.2 [95% CI, -1.1 to 0.7]). One study reported significantly higher pain scores at 1 hour postoperation in the FIB group compared with the LAI group (5.5 vs 3.4; P = .02). Another study reported significantly greater total analgesic consumption (in morphine equivalent dosing) in the PACU among the FIB group compared with the LPB group (20.8 vs 17.0; P = .02). No significant differences were observed in total PACU analgesic consumption between FIB and other analgesic modalities. CONCLUSION: In patients undergoing hip arthroscopy, the FIB does not appear to demonstrate superiority to other forms of analgesics in the immediate postoperative period. Therefore, it is not recommended as a routine form of pain control for these procedures.

BACKGROUND: Little is known regarding the effect of early active elbow range of motion (ROM) protocols on failure rates and outcomes after open subpectoral biceps tenodesis. HYPOTHESIS: We hypothesized that patients managed using an early active ROM protocol after open subpectoral biceps tenodesis would demonstrate similar failure rates and functional outcomes compared to patients managed using a traditional delayed active ROM protocol. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: We evaluated 63 patients who underwent open subpectoral biceps tenodesis with unicortical suture button fixation. Based on surgeon preference, 22 patients were managed using an early active motion protocol consisting of no restrictions on elbow flexion or forearm supination, while 41 patients were managed using a delayed motion protocol postoperatively. Primary outcome measures included failure of biceps tenodesis and American Shoulder and Elbow Surgeons (ASES) and Single Assessment Numeric Evaluation (SANE) scores. Secondary outcomes included shoulder and elbow ROM at 6 months postoperatively. RESULTS: The mean follow-up for the 63 patients was 24.2 months postoperatively. One patient (2.4%) in the delayed active motion cohort and no patients in the early active motion cohort experienced failure. Final outcome scores as well as 6-month shoulder and elbow ROM indicated excellent functional outcomes, with no significant difference between motion cohorts. The median postoperative ASES scores were 97.99 in the early active motion cohort (mean ± standard deviation [SD], 95.49 ± 7.68) and 95.42 in the delayed motion cohort (mean ± SD, 90.93 ± 16.08), while median postoperative SANE scores were 96 in the early motion cohort (mean ± SD, 94.23 ± 6.68) and 95 in the delayed motion cohort (mean ± SD, 88.39 ± 17.98). Subgroup analysis demonstrated no significant difference in outcome scores based on the performance of concomitant rotator cuff repair or hand dominance. CONCLUSION: Early active ROM after open subpectoral biceps tenodesis with unicortical suture button fixation resulted in low failure rates and excellent clinical outcomes, comparable to the results of patients managed using delayed active ROM protocols. This suggests that patients undergoing open subpectoral biceps tenodesis may be managed using either early or delayed active motion protocols without compromising functional outcome.
RESUMEN
CASE: A 26-year-old man presented to the emergency department with atraumatic right leg pain after a period of low-impact activity. He was discharged and returned 3 days later with findings of acute compartment syndrome. CONCLUSION: We present a case of delayed diagnosis of acute exertional compartment syndrome (AECS) in the setting of rhabdomyolysis, leading to detrimental sequelae. Practitioners with a high degree of clinical suspicion can make a prompt and accurate diagnosis by physical examination alone, allowing early treatment of AECS.
