Intersurgeon Variability of Minimal Clinically Important Difference for Worsening Achievement Rates After Total Joint Arthroplasty.

BACKGROUND: Using the Patient-Reported Outcome Measurement Information System, we sought to evaluate surgeon performance variability via minimal clinically important difference for worsening (MCID-W) achievement rates in primary and revision total knee and hip arthroplasty. METHODS: This retrospective study analyzed 3,496 primary total hip arthroplasty (THA), 4,622 primary total knee arthroplasty (TKA), 592 revision THA, and 569 revision TKA patients. Patient factors collected included demographics, comorbidities, and Patient-Reported Outcome Measurement Information System physical function short form 10a scores. Surgeon factors collected included caseload, years of experience, and fellowship training. The MCID-W rate was calculated as the percent of patients in each surgeon's cohort who achieved MCID-W. Distribution was presented via a histogram with associated average, standard deviation, range, and interquartile range (IQR). Linear regressions were performed to evaluate the potential correlation between surgeon- and patient-level factors with MCID-W rate. RESULTS: The average MCID-W rates of the surgeons represented in the primary THA and TKA cohorts were 12.7 ± 9.2% (range, 0 to 35.3%; IQR, 6.7 to 15.5%) and 18.0 ± 8.2% (range, 0 to 36%; IQR, 14.3 to 22.0%). The average MCID-W rates among the revision THA and TKA surgeons were 36.0 ± 22.2% (range, 9.1 to 90%; IQR, 25.0 to 41.4%) and 21.2 ± 7.7% (range, 8.1 to 37.0%; IQR, 16.6 to 25.4%). Strong correlations were not found between patient- or surgeon-level factors and MCID-W rate of the surgeon. CONCLUSION: We demonstrated variance in MCID-W achievement rates across surgeons in both primary and revision joint arthroplasty, independent of patient- or surgeon-level factors.

How do underserved adolescents want to learn about health? An exploration of health concerns, preferences, and resources utilized.

Understanding health concerns and preferences of underserved adolescents has potential to shape health interventions. The objective of this study is to better understand these adolescents' current and preferred health resources, prior to the COVID-19 pandemic. High school students from underrepresented communities in six US cities completed a pre-pipeline program survey in which they reported level of personal concern, as well as current and preferred sources of information about 1) depression/anxiety, 2) nutrition, 3) sexual health, 4) trauma/violence, and 5) alcohol/drugs. 259 participants completed the survey (avg. age 15.7, 79% female, 58.3% Hispanic, and 36.0% Black). At least a moderate level of concern and some degree of prior knowledge (>3 on 5-point Likert scale) were reported across all health topics. Participants reported the lowest level of knowledge on the topic of trauma/violence. Students reported family (24%) and teachers (21%) as the most utilized current sources of information. Students reported doctors as the preferred source of information across all health topics. The difference between students' current source of information and preferred source of information was significant across four topics: depression/anxiety, sexual health, trauma, and alcohol/drugs (p <0.01). These results underscore the important role of physicians as educators and suggest a need for improved education on trauma/violence. These results also establish a pre-COVID-19 baseline for adolescent health concerns, current, and preference health resources. This baseline understanding may shift because of pandemic changes.

Arthroscopic Management of Meniscal Cysts: A Systematic Review.

PURPOSE: The purpose of this study was to systematically review the outcomes of arthroscopic management of meniscal cysts and to compare the results across the reported surgical techniques. METHODS: Following the PRISMA methodology, 3 databases (PubMed, Scopus and Web of Science) were searched from inception to June 2021 for randomized controlled trials (RCTs) and observational studies reporting outcomes on patients with meniscal cysts who underwent arthroscopic surgery. The Mixed Methods Appraisal Tool (MMAT) was used to evaluate the study quality. RESULTS: Eighteen studies examining 753 patients (761 meniscal cysts; 92.5% in the lateral meniscus) were included. Overall, 486/736 (66.0%) patients underwent purely arthroscopic decompression, 174/736 (23.6%) received arthroscopic excision, 58/736 (7.9%) received arthroscopy assisted percutaneous drainage, and 18/736 (2.4%) received a combined procedure. The recurrence rate for meniscal cysts was 7.1% across all arthroscopic procedures; 8.3%, 3.4%, and 0% for arthroscopic decompression, arthroscopic excision, and arthroscopy assisted percutaneous drainage, respectively. A total of 79.3% of patients returned to the same level of sport and 85.7% had resolution or minimal knee symptoms after arthroscopic surgery for meniscal cysts. Patient perception of surgical outcomes after any type of arthroscopic surgery for meniscal cysts was reported by 5 studies, with 189/203 (93.1%) reporting satisfaction with their surgical procedure. CONCLUSION: Based on current evidence, arthroscopic management of meniscal cysts yields satisfactory patient outcomes, low cyst recurrence rates and high return to sport rates regardless of the surgical technique. Rates of cyst recurrence were relatively higher with arthroscopic decompression versus excision and percutaneous drainage; however, prospective studies using modern surgical techniques are necessary to better evaluate the surgical outcomes and to compare those with nonoperative modalities, given that a significant proportion of the included articles in this review were relatively outdated. LEVEL OF EVIDENCE: Systematic review of level II and IV studies.

Injury Epidemiology and Time Lost From Participation in Women's NCAA Division I Indoor Versus Beach Volleyball Players.

BACKGROUND: Beach volleyball officially became a National Collegiate Athletic Association (NCAA) Division I sport in 2015-2016. Few studies have examined the epidemiology of injuries in indoor versus beach volleyball in NCAA Division I athletes. PURPOSE: To compare the epidemiology of injuries and time lost from participation between female NCAA Division I athletes who participate in indoor versus beach volleyball. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Injury surveillance data (2003-2020) were obtained using an institutional database for all NCAA Division I women's beach or indoor volleyball athletes. The total injury rate was expressed per 1000 hours played. The injury rate per body site was calculated by dividing the number of injuries in each body region by the total number of injuries. The frequency of injury per body site was also expressed as number of injuries per 1000 hours of practice or number of injuries per 1000 hours of game. The injury rate (total and per body site) and time lost from participation were compared between indoor and beach volleyball athletes. RESULTS: Participants were 161 female NCAA Division I volleyball athletes (53 beach volleyball and 108 indoor volleyball athletes). In total, 974 injuries were recorded: 170 in beach volleyball and 804 in indoor volleyball. The injury rates for beach versus indoor volleyball were 1.8 versus 5.3 injuries per 1000 hours played (P < .0001). Indoor volleyball athletes had significantly higher injury rates compared with beach volleyball players for concussion (7.5% vs 6.5%; P < .0001) and knee injury (16.7% vs 7.6%; P = .0004); however, the rate of abdominal muscle injury was significantly higher in beach versus indoor volleyball (11.8% vs 4.7%; P = .0008). Time lost from sport participation was significantly longer in beach versus indoor volleyball for knee (24 vs 11 days; P = .047), low back (25 vs 17 days; P = .0009), and shoulder (52 vs 28 days; P = .001) injuries. CONCLUSION: Based on this study, injury was more likely to occur in indoor compared with beach volleyball. Sport-related concussion and knee injuries were more common in indoor volleyball, but the rate of abdominal muscle injury was higher in beach volleyball. Beach volleyball players needed longer time to recover after injuries to the knee, low back, and shoulder.

Ballistic trauma patients have decreased early narcotic demand relative to blunt trauma patients: Blunt ballistic injury opioid use.

OBJECTIVES: Blunt and ballistic injuries are two common injury mechanisms encountered by orthopaedic traumatologists. However the intrinsic nature of these injures may necessitate differences in operative and post-operative care. Given the evolving opioid crisis in the medical community, considerable attention has been given to appropriate management of pain; particularly in orthopaedic patients. We sought to evaluate relative postoperative narcotic use in blunt injuries and ballistic injuries. DESIGN: Retrospective Cohort Study. SETTING: Academic Level-1 Trauma Center. PATIENTS: 96 Patients with blunt or ballistic fractures. INTERVENTION: Inpatient narcotic pain management after orthopaedic fracture management. MAIN OUTCOME MEASUREMENTS: Morphine equivalent units (MEU). RESULTS: Patients with blunt injuries had a higher MEU compared to ballistic injuries in the first 24 hours postoperatively (35.0 vs 29.5 MEU, p=0.02). There were no differences in opiate consumption 24-48 hours (34.8 vs 28.0 MEU), 48 hours - 7 days post op (28.4 vs 30.4 MEU) or the 24 hours before discharge (30.0 vs 28.6 MEU). On multivariate analysis, during the 24-48 hours and 24 hours before discharge timepoints total EBL was associated with increased opioid usage. During days 3-7 (p<0.001) and in the final 24 hours prior to discharge (p=0.012), the number of orthopaedic procedures was a predictor of opioid consumption. CONCLUSION: Blunt injuries required an increased postoperative narcotic consumption during the first 24 hours of inpatient stay following orthopedic fracture fixation. However, there was no difference at other time points. Immediate post-operative pain regimens may be decreased for patients with ballistic injuries. LEVEL OF EVIDENCE: III.

Surgical Management of Shoulder and Knee Instability in Patients with Ehlers-Danlos Syndrome: Joint Hypermobility Syndrome.

Ehlers-Danlos Syndrome (EDS) is a hereditary disorder of the connective tissue, which has been classified into numerous subtypes over the years. EDS is generally characterized by hyperextensible skin, hypermobile joints, and tissue fragility. According to the 2017 International Classification of EDS, 13 subtypes of EDS have been recognized. The majority of genes involved in EDS are either collagen-encoding genes or genes encoding collagen-modifying enzymes. Orthopedic surgeons most commonly encounter patients with the hypermobile type EDS (hEDS), who present with signs and symptoms of hypermobility and/or instability in one or more joints. Patients with joint hypermobility syndrome (JHS) might also present with similar symptomatology. This article will focus on the surgical management of patients with knee or shoulder abnormalities related to hEDS/JHS.

Knee Arthroscopy After Total Knee Arthroplasty: Not a Benign Procedure.

BACKGROUND: Outcomes of knee arthroscopy (KA) after total knee arthroplasty (TKA) have been limited to small case series with short-term follow-up. The purpose of this study is to report the outcomes of patients who undergo a KA after a TKA using a large longitudinal database. METHODS: The PearlDiver Medicare database was queried for patients who underwent a KA procedure after a TKA on the ipsilateral extremity. A randomly selected control group was created by matching controls to cases in a 3:1 ratio based on age, gender, year of procedure, and Elixhauser Comorbidity Index. Revision for infection and all-cause revision were used as end points. RESULTS: A total of192 TKA patients who underwent a subsequent KA (TKA + KA group) were compared to 571 TKA patients who did not have a subsequent KA (TKA - KA group). The incidence of revision for infection was 6.3% in the TKA + KA group compared to 2.2% in the TKA - KA group (odds ratio, 2.87; P = .009). The incidence of all-cause revision was 18.8% in the TKA + KA group compared to 5.1% in the TKA - KA group (odds ratio, 4.34; P < .001). CONCLUSION: KA after TKA was associated with increased infection-related and all-cause revision. The association between KA and subsequent infection requires further investigation.
