Patient-reported allergies are associated with increased rate of postoperative stiffness after arthroscopic rotator cuff repair.

BACKGROUND: Several risk factors have been identified for the development of postoperative shoulder stiffness, and there has been increasing interest in orthopedic literature regarding patient-reported allergy (PRA) as an identifiable risk factor for adverse outcomes. The purpose of this study is to determine whether PRAs are associated with subsequent rates of diagnosis of adhesive capsulitis (AC) or return to the operating room for postoperative shoulder stiffness within 2 years after arthroscopic rotator cuff repair (ARCR). METHODS: Current Procedural Terminology surgical billing codes were used to retrospectively identify patients who underwent ARCR at a single urban academic institution from January 2012 to December 2020 with minimum 2-year follow-up. Lysis of adhesions (LOA), manipulation under anesthesia (MUA), and AC of the shoulder were further queried within 2 years postoperatively for the ipsilateral shoulder. Patients were excluded if they had undergone ipsilateral MUA/LOA or received a diagnosis of AC before the index procedure. Demographic characteristics and medical comorbidities (hypertension, diabetes, hyperlipidemia, and hypothyroidism) were extracted from electronic medical records. Baseline characteristics were compared between patients with and without PRAs. Multivariate logistic regression analyses were performed to determine the association of the presence of PRAs overall, as well as the presence of 1, 2, or 3 or more PRAs, with subsequent MUA/LOA or diagnosis of AC within 2 years postoperatively. RESULTS: Of 7057 patients identified in the study period, 6583 were eligible for the final analysis. The mean age was 56.6 ± 11.7 years, and the mean body mass index was 29.1 ± 5.6. Overall, 19.3% of patients (n = 1271) reported at least 1 allergy, and 7.1% (n = 469) had >1 PRA. A total of 44 patients (0.7%) underwent subsequent ipsilateral MUA/LOA within 2 years postoperatively, whereas 93 patients (1.4%) received a diagnosis of ipsilateral AC in the same time frame. PRAs were significantly associated with subsequent diagnosis of AC (odds ratio [OR]: 2.39; 95% confidence interval [CI]: 1.45-3.92; P < .001), but not MUA/LOA (OR: 1.97, 95% CI: 1.26-3.61; P = .133). Patients with 2 PRAs had greater odds of being diagnosed with AC than patients with 1 PRA (OR: 2.74; 95% CI: 1.14-5.99; P = .012). Although this association was nonsignificant for MUA/LOA, patients with 2 PRAs (OR: 2.67; 95% CI: 0.96-8.80; P = .059) demonstrated a similar statistical trend. CONCLUSION: PRAs are associated with increased odds of receiving a diagnosis of AC within 2 years after ARCR but were not found to be associated with return to the operating room for postoperative stiffness.

Decision-Making Regarding Newborn Circumcision: A Qualitative Analysis.

OBJECTIVES: Circumcision of newborn males is left to parental preference, as medical necessity has not been demonstrated. For medical providers seeking to help parents make decisions and provide informed consent, there is little information regarding how parents gather and process information about circumcision. This study aimed to characterize the comprehensive range of parental attitudes, gaps in knowledge, and decision-making regarding circumcision. METHODS: Qualitative data was obtained from semi-structured open-ended interviews conducted during the postpartum hospitalization. Interviews were recorded, transcribed, and coded by multiple independent reviewers. A grounded theory approach was used to identify emergent themes regarding attitudes towards, sources of information about, and decision-making surrounding circumcision. RESULTS: Ten mothers were interviewed, of whom six planned to circumcise and four did not. Major themes emerged: the importance of cultural norms, limited yet influential discussions, and the lack of, but desire for, more knowledge. Discussions with medical providers were often limited, though when physician conversation was more extensive, provider input was highly influential. Parents lacked evidence-based knowledge of the risks and benefits of the procedure. They uniformly desire more information and counseling from their medical providers. CONCLUSIONS FOR PRACTICE: This study affirms the importance of sociocultural factors and identified a discrepancy between parents' desire for empiric information and the counsel offered by providers, identifying a need for improved parent counseling. The qualitative themes that emerged from this work enabled the development of a comprehensive conceptual model that can be further tested to develop a decision aid for circumcision of the newborn.

Isolated Acetabuloplasty for Femoroacetabular Impingement: Favorable Patient-Reported Outcomes and Sustained Survivorship at Minimum 5-Year Follow-Up.

PURPOSE: To evaluate minimum 5-year outcomes and conversion rate to total hip arthroplasty (THA) for the treatment of femoroacetabular impingement (FAI) syndrome with an isolated acetabular osteoplasty. METHODS: Patients undergoing hip arthroscopy with an isolated acetabular osteoplasty from March 2009 to June 2014 for FAI syndrome with pincer and/or cam morphology and a labral tear were identified. Those who underwent femoroplasty or prior ipsilateral hip surgery or who had previous hip conditions, ipsilateral hip dysplasia, or a Tönnis grade higher than 2 were excluded. Patient-reported outcomes (PROs) collected included Patient-Reported Outcomes Measurement Information System (PROMIS) scores specific to physical functioning and pain interference, modified Harris Hip Score, International Hip Outcome Tool 12, Hip Outcome Score-Activities of Daily Living, Hip Outcome Score-Sport-Specific Subscale, and Numeric Pain Rating Scale. Patients were also queried about secondary surgical procedures and conversion to THA. RESULTS: We identified 86 patients at minimum 5-year follow-up (average, 7.4 years). The average patient age was 39.8 ± 12.3 years, 70.9% of patients were female, and 7% of patients had Tönnis grade 2. The mean PRO scores were 52.0 ± 8.9 for the PROMIS physical functioning score, 39.6 ± 7.5 for the PROMIS pain interference score, 78.7 ± 12.0 for the modified Harris Hip Score, 73.3 ± 23.1 for the International Hip Outcome Tool 12 score, 89.9 ± 12.0 for the Hip Outcome Score-Activities of Daily Living, and 81.4 ± 21.0 for the Hip Outcome Score-Sport-Specific Subscale. Of the patients, 72.1% achieved the patient acceptable symptomatic state (PASS) according to previously established PASS scores for FAI syndrome treated with hip arthroscopy at minimum 5-year follow-up. The overall rate of revision arthroscopy was 3.5%, and the rate of conversion to THA was 5.8%. CONCLUSIONS: An isolated acetabular osteoplasty can provide sustained clinical benefits for the treatment of FAI syndrome with labral tears, with good to excellent PROs and PASS rates and a low rate of conversion to THA at minimum 5-year follow-up. LEVEL OF EVIDENCE: Level IV, case series.

Risk factors for 30-day readmission following hip arthroscopy.

PURPOSE: Hip arthroscopy is known to be safe with low rates of postoperative complications. The purpose of this study is to evaluate hip arthroscopy cases in a national surgical database to identify risk factors associated with readmission. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2012 to 2016 for current procedural terminology billing codes related to hip arthroscopy. International Classification of Diseases diagnostic codes were used to exclude cases involving infection, fracture, or open procedures. Univariate and multivariate analyses were performed to identify risk factors associated with 30-day readmission. RESULTS: 1493 patients were identified who had undergone hip arthroscopy. The most common procedures were labral resection or chondroplasty (n = 589, 39.5%) and femoroplasty (n = 527, 35.3%). The 30-day complication rate was 1.7% and the most common complications following the procedure were bleeding (n = 12, 0.8%) superficial infections (n = 5, 0.3%), and returning to the operating room (n = 4, 0.3%). The 30-day readmission rate was 1.3%. On multivariate analysis, hypertension requiring anti-hypertensive medication (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.4-8.7) and chronic corticosteroid or immunosuppressant use (OR 7.2; 95% CI 1.9-26.7) were identified as independent risk factors for readmission. There was no difference in complication rates when hip arthroscopy was performed with isolated femoroplasty (n = 340), isolated acetabuloplasty (n = 103), both (n = 187) or neither (n = 863). CONCLUSION: These findings confirm that the 30-day readmission (1.3%) and complication rate (1.7%) are low for isolated hip arthroscopy procedures; however, hypertension and chronic steroid use are independent risk factors for readmission. LEVEL OF EVIDENCE: Retrospective comparative study, Level III.

Management of Humeral Shaft Fracture: A Network Meta-Analysis of Individual Treatment Modalities.

OBJECTIVE: The purpose of this study was to perform a network meta-analysis of level I and II evidence comparing different management techniques to define the optimum treatment method for humeral shaft fractures (HSFs). DATA SOURCES: A systematic review of the literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines of MEDLINE, Embase, and Cochrane Library was screened from 2010 to 2023. STUDY SELECTION: Inclusion criteria were evidence level I or II studies comparing nonoperative and/or operative repair techniques including open reduction internal fixation plate osteosynthesis (ORIF-Plate), minimally invasive percutaneous plating (MIPO), and intramedullary nail (IMN) fixation for the management of HSFs (OTA/AO 12A, B, C). DATA EXTRACTION: The risk of bias and methodologic quality of evidence were assessed according to the guidelines designed by the Cochrane Statistical Methods Group and Cochrane Methods Bias Group. DATA SYNTHESIS: Network meta-analysis was conducted with a frequentist approach with a random-effects model using the netmeta package version 0.9-6 in R. RESULTS: A total of 25 studies (1908 patients) were included. MIPO resulted in the lowest complication rate (2.1%) when compared with ORIF-Plate (16.1%) [odds ratio (OR), 0.13; 95% confidence interval (CI), 0.04-0.49]. MIPO resulted in the lowest nonunion rate (0.65%) compared with all management techniques (OR, 0.28; 95% CI, 0.08-0.98), whereas Non-Op resulted in the highest (15.87%) (OR, 3.48; 95% CI, 1.98-6.11). MIPO demonstrated the lowest rate of postoperative radial nerve palsy overall (2.2%) and demonstrated a significantly lower rate compared with ORIF-Plate (OR, 0.22; 95% CI, 0.07-0.71, P = 0.02). IMN resulted in the lowest rate of deep infection (1.1%) when compared with ORIF-Plate (8.6%; P = 0.013). MIPO resulted in a significantly lower Disabilities of the Arm, Shoulder, and Hand score (3.86 ± 5.2) and higher American Shoulder and Elbow Surgeons score (98.2 ± 1.4) than ORIF-Plate (19.5 ± 9.0 and 60.0 ± 5.4, P < 0.05). CONCLUSION: The results from this study support that surgical management results in better postoperative functional outcomes, leads to higher union rates, reduces fracture healing time, reduces revision rate, and decreases malunion rates in patients with HSFs. In addition, MIPO resulted in statistically higher union rates, lowest complication rate, lowest rate of postoperative radial nerve palsy, and lower intraoperative time while resulting in better postoperative Disabilities of the Arm, Shoulder, and Hand and American Shoulder and Elbow Surgeons scores when compared with nonoperative and operative (ORIF and IMN) treatment modalities. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

On the Rise: The Increasing Frequency of Pediatric Shoulder Stabilization Surgery in Children and Adolescents.

The management of shoulder instability in children and adolescents continues to evolve. The purpose of this study was to evaluate the epidemiology of shoulder stabilization procedures in a large, nationally representative pediatric population. The Pediatric Health Information System (PHIS) database was queried for patients 18 years and younger undergoing surgical shoulder stabilization between 2008 and 2017. Patients undergoing arthroscopic surgery were compared with patients undergoing complex (open or bony augment stabilization) procedures. Annual trends were calculated using linear regression. A total of 3925 procedures were performed, of which 92.9% were arthroscopic Bankart repairs. There was a significant increase in overall pediatric shoulder stabilizations and arthroscopic repairs between 2008 and 2017. Complex procedures were performed most often in the Northeast, but the annual frequency did not increase nationally. [Orthopedics. 2023;46(3):e167-e172.].

Outcomes following arthroscopic repair of humeral avulsion of the glenohumeral ligament (HAGL) lesion: A systematic review.

Purpose: The purpose of this systematic review was to evaluate patient outcomes following arthroscopic surgical management for a humeral avulsion of the glenohumeral ligament (HAGL) lesion. Methods: Based on PRISMA guidelines, two independent reviewers performed a literature search to isolate studies on arthroscopic HAGL repair. The functional outcomes, return to play (RTP), and recurrent instability from each study were extracted and analyzed. Results: Overall, 7 manuscripts were included with 49 patients. The patient population was 61.4% male with a mean age of 24.8 years (15-42 years), and 41.9 months of follow-up on average (12-104 months). The Rowe score was the most frequently reported outcome measure with a weighted mean of 89. In total, 81.2% of patients reported being able to RTP post-operatively, with 70.5% reported being able to play at an equal or higher level. There was 1 recurrent dislocation (2%). Conclusion: The current study found successful clinical outcomes following the arthroscopic management of HAGL lesions. Recurrent dislocation requiring revision was rare, with high rates of return to play including those who could return to the same level of play. However, the paucity of evidence does not permit a statement of best-practice to be made.

Injury Risk in Collegiate Football Players With Generalized Joint Hypermobility: A Prospective Cohort Study Over 2 Years.

Background: Generalized joint hypermobility (GJH) has been identified as a risk factor for injury in various athletic patient populations. Purpose: To evaluate GJH as a predisposing risk factor for injury in a population of National Collegiate Athletic Association (NCAA) Division I football players. Study Design: Cohort study; Level of evidence, 2. Methods: The Beighton score was collected for 73 athletes during their preseason physical examinations in 2019. GJH was defined as a Beighton score ≥4. Athlete descriptive characteristics, including age, height, weight, and playing position, were recorded. The cohort was evaluated prospectively for 2 years, and the number of musculoskeletal issues, injuries, treatment episodes, days unavailable, and surgical procedures for each athlete during this period were recorded. These measures were compared between the GJH and no-GJH groups. Results: The mean Beighton score was 1.4 ± 1.5 for the 73 players; 7 players (9.6%) had a Beighton score indicating GJH. During the 2-year evaluation, there were 438 musculoskeletal issues, including 289 injuries. The mean number of treatment episodes per athlete was 77 ± 71 (range, 0-340), and the mean number of days unavailable was 67 ± 92 days (range, 0-432 days). There were 23 athletes who required 25 operations, the most common procedure being arthroscopic shoulder stabilization (n = 6). The number of injuries per athlete was not significantly different between the GJH and no-GJH groups (3.0 ± 2.1 vs 4.1 ± 3.0; P = .13), nor were there any between-group differences in the number of treatments received (74.6 ± 81.9 vs 77.2 ± 71.5; P = .47), days unavailable (79.6 ± 124.5 vs 65.3 ± 89.3; P = .61), or rates of surgery (43% vs 30%; P = .67). Conclusion: A preseason diagnosis of GJH did not place NCAA football players at a greater risk for injury during the 2-year study period. Based on the findings of this study, no specific preparticipation risk counseling or intervention is warranted for football players who are diagnosed with GJH as defined by the Beighton score.

Angiotensin Receptor Blockers and Angiotensin-Converting Enzyme Inhibitors Have No Significant Relationship With Postoperative Arthrofibrosis After Shoulder Arthroscopy.

Purpose: To determine the effect of perioperative angiotensin II receptor blocker (ARB) or angiotensin-converting enzyme inhibitors (ACEi) on postoperative arthrofibrosis, as defined by requiring manipulation under anesthesia (MUA) or new diagnosis of adhesive capsulitis (AC) following arthroscopic shoulder procedures. Methods: Patients were retrospectively identified using Current Procedural Terminology surgical billing codes to identify patients who underwent any shoulder arthroscopic procedure at a single urban academic institution from 2012 to 2020 with a minimum 2-year follow-up. Patients were excluded if <30 years old at time of surgery, as these patients rarely use ARB and ACEi medications, or if they had pre-existing AC. Demographics, active medication prescriptions at the time of surgery, and medical comorbidities were recorded. Multivariable logistic regression was performed to determine the effect of ARB/ACEi on subsequent MUA or AC by 90 days, 1 year, and 2 years. Results: In total, 5,559 patients were included in the final analysis. A majority of the cohort (53.4%) underwent arthroscopic surgery between the ages of 50 to 69 years. Most patients were male (61.8%) and without obesity (67.3%). In total, 18.9% and 15.0% were taking an ARB or ACEi medication perioperatively, respectively. Within 2 years' postoperatively, 51 patients (0.9%) underwent subsequent ipsilateral MUA, and 174 patients (3.1%) developed AC. Patients taking ARBs had a 17.5% rate of postoperative arthrofibrosis within 2-years compared with 19.1% in those not on ARBs, although this difference was not significant (P = .58). Likewise, no significant difference was found between those taking ACEi versus not (15.0% vs 15.0%, P = .99). Individual generic ARB/ACEi subgroup analysis did not demonstrate any significant associations with rate of postoperative arthrofibrosis (P > .05). Conclusions: ARBs or ACEi did not significantly affect the rate of postoperative arthrofibrosis following shoulder arthroscopy, however female sex, diabetes mellitus, and Black/African American race were associated with an increased rate of necessitating MUA or developing AC within 2 years postoperatively. Level of Evidence: Level III, retrospective cohort study.

The children's brain tumor network (CBTN) - Accelerating research in pediatric central nervous system tumors through collaboration and open science.

Pediatric brain tumors are the leading cause of cancer-related death in children in the United States and contribute a disproportionate number of potential years of life lost compared to adult cancers. Moreover, survivors frequently suffer long-term side effects, including secondary cancers. The Children's Brain Tumor Network (CBTN) is a multi-institutional international clinical research consortium created to advance therapeutic development through the collection and rapid distribution of biospecimens and data via open-science research platforms for real-time access and use by the global research community. The CBTN's 32 member institutions utilize a shared regulatory governance architecture at the Children's Hospital of Philadelphia to accelerate and maximize the use of biospecimens and data. As of August 2022, CBTN has enrolled over 4700 subjects, over 1500 parents, and collected over 65,000 biospecimen aliquots for research. Additionally, over 80 preclinical models have been developed from collected tumors. Multi-omic data for over 1000 tumors and germline material are currently available with data generation for > 5000 samples underway. To our knowledge, CBTN provides the largest open-access pediatric brain tumor multi-omic dataset annotated with longitudinal clinical and outcome data, imaging, associated biospecimens, child-parent genomic pedigrees, and in vivo and in vitro preclinical models. Empowered by NIH-supported platforms such as the Kids First Data Resource and the Childhood Cancer Data Initiative, the CBTN continues to expand the resources needed for scientists to accelerate translational impact for improved outcomes and quality of life for children with brain and spinal cord tumors.

Are two plates better than one? A systematic review of dual plating for acute midshaft clavicle fractures.

Background: The rate of operative fixation of acute midshaft clavicle fractures has exponentially increased in recent years; however, the rate of reoperation for symptomatic hardware removal remains high and the optimal fixation strategy unknown. This systematic review aimed to summarize available evidence for dual plating of acute displaced midshaft clavicle fractures. Methods: EMBASE, MEDLINE, and PubMed searches identified clinical studies evaluating dual plate fixation of acute midshaft clavicle fractures. Pooled analysis was performed using a random-effects model in RevMan 5.3. Results: Eleven studies including 672 patients were included. Hardware removal occurred in 4.4% and 12.3% of patients undergoing dual and single plate fixation, respectively. Compared to single plating, dual plating had significantly lower odds of hardware removal (P = 0.001) with no difference in union rates. There were no significant differences in reoperation (excluding hardware removal), complications, and patient-reported outcomes between the two groups (P > 0.05). Conclusions: This study suggests that dual plating of acute displaced midshaft clavicle fractures may lead to lower rates of reoperation for symptomatic hardware removal without compromising fracture healing. Ultimately, well-designed randomized trials are needed to further investigate the findings from this systematic review.

An eponymous history of the anterolateral ligament complex of the knee.

BACKGROUND: Recent interest has surged in the anterolateral ligament (ALL) and complex (ALC) of the knee. Its existence and role in rotary stability of the knee, particularly in the setting of anterior cruciate ligament (ACL) reconstruction, remains a contentious and controversial topic. UNDERSTANDING THE ALC: We must review our history and recognize the pioneers who pushed our understanding of the ALL forward before it was popularly recognized as a discrete structure. Additionally, given that many eponyms remain in common use related to the ALC, we must standardize our nomenclature to prevent misuse or misunderstanding of terms in the literature. In this review, modern understanding of the anterolateral ligament complex (ALC) is traced to 1829 by exploring eponymous terms first in anatomy and then in surgical technique. Understanding our history and terminology will allow us to better understand the ALC itself. CONCLUSION: This review aims to provide historical context, define terminology, and provide insight into the clinical relevance of the ALC.

A Qualitative Assessment of Return to Sport in Collegiate Athletes: Does Gender Matter?

INTRODUCTION: Participation of female athletes in collegiate athletics continues to rise, but there remains a significant underrepresentation of this growth in the literature and lack of knowledge regarding the impact of gender on the college athlete experience. Our goal was to explore how collegiate female and male athletes perceive and approach return to sport after orthopaedic surgery. METHODS: Semi-structured, open-ended interviews were conducted with collegiate varsity athletes from a single institution who underwent orthopaedic surgery following injury with at least two years follow-up. Athletes were asked about factors influencing recovery, rehabilitation, and their return to or retirement from sport. Codes, categories, and themes were derived within and across genders. RESULTS: Fifteen athletes (six females and nine males) were interviewed individually. Athletes shared similar experiences following injury, citing similar motivations driving them back to sport. Athletes stressed the importance of the athlete role to their identity regardless of gender. Our analysis revealed two gender-related challenges: male athletes commonly felt weight change was a barrier to successful recovery and often led to self-consciousness; while females expressed frustrations in lack of empathy from those they turned to for support. CONCLUSION: Female and male athletes shared some common supporting and challenging factors in return to sport following orthopaedic surgery. The most important findings of the present study were the differentiated challenges male versus female athletes experienced. Female athletes found difficulty with interpersonal relationships and external support, while male athletes struggled internally with their own body image and changing self-concept. This qualitative study provides a nuanced look at the experience of varsity athletes returning to sport following surgery. An understanding of the gendered experiences of collegiate athletes is critical to ensure all athletes in this unique population are supported as they cope with injury and seek to return to sport.

Bilateral versus unilateral hip arthroscopy for femoroacetabular impingement: a systematic review.

One in four patients presenting with femoroacetabular impingement (FAI) has bilateral symptoms, and despite excellent outcomes reported after arthroscopic treatment of FAI, there remains a paucity of data on the outcomes following bilateral hip arthroscopy. This systematic review aims to examine the outcomes following bilateral (either 'simultaneous' or 'staged') versus unilateral hip arthroscopy for FAI. A systematic review of multiple electronic databases was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and checklist. All studies comparing simultaneous, staged and/or unilateral hip arthroscopy for FAI were eligible for inclusion. Case series, case reports and reviews were excluded. All study, patient and hip-specific data were extracted and analyzed. The Newcastle-Ottawa Scale was used to assess study quality. A meta-analysis was not performed due to heterogeneity among outcome measures. A total of six studies, including 722 patients (42.8% male) and 933 hips were eligible for inclusion. The mean age across patients was 35.5. The average time between staged procedures was 7.7 months. Four of the six studies were retrospective cohort studies, while the remaining two were prospective in nature. The overall quality of the eligible studies was found to be good. No significant difference was noted among patient-reported outcomes (modified Harris hip score, hip outcome score and non-arthritic hip score), visual analog scale, return to sport, traction time and complications between those undergoing bilateral (simultaneous or staged) versus unilateral hip arthroscopy. Based on the current available evidence, bilateral hip arthroscopy (whether simultaneous or staged) exhibits similar efficacy and safety when compared with unilateral hip arthroscopy. However, further prospective study is required to confirm this finding.

Risk Factors for 30-Day Readmission following Knee Arthroscopy.

This study evaluates knee arthroscopy cases in a national surgical database to identify risk factors associated with readmission. The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2012 to 2016 for billing codes related to knee arthroscopy. International Classification of Diseases diagnostic codes were then used to exclude cases which involved infection. Patients were subsequently reviewed for readmission within 30 days. Univariate and multivariate analyses were then performed to identify risk factors associated with 30-day readmission. A total of 69,022 patients underwent knee arthroscopy. The overall 30-day complication rate was 1.75% and the 30-day readmission rate was 0.92%. On multivariate analysis, age > 60 years (odds ratio [OR], 1.29; 95% confidence interval [CI], 1.07-1.55), smoking (OR, 1.40; 95% CI, 1.15-1.70), recent weight loss (OR, 13.22; 95% CI, 5.03-34.73), chronic obstructive pulmonary disease (OR, 1.98; 95% CI, 1.39-2.82), hypertension (OR, 1.48; 95% CI, 1.23-1.78), diabetes (OR, 1.92; 95% CI, 1.40-2.64), renal failure (OR, 10.65; 95% CI, 2.90-39.07), steroid use within 30 days prior to the procedure (OR, 1.91; 95% CI, 1.24-2.94), American Society of Anesthesiologists (ASA) class ≥ 3 (OR, 1.69; 95% CI, 1.40-2.04), and operative time > 45 minutes (OR, 1.68; 95% CI, 1.42-2.00) were identified as independent risk factors for readmission. These findings confirm that the 30-day overall complication (1.75%) and readmission rates (0.92%) are low for knee arthroscopy procedures; however, age > 60 years, smoking status, recent weight loss, chronic obstructive pulmonary disease, hypertension, diabetes, chronic steroid use, ASA class ≥ 3, and operative time > 45 minutes are independent risk factors for readmission.
