What Are the Trends in Women's Representation Among Lead Investigators of Orthopaedic Clinical Trials?

Background: Serving as a principal investigator for a clinical trial can bring national visibility and recognition to physicians, and it can have a substantial impact on their promotion and tenure. In the field of orthopaedics, there is a well-known gender gap in terms of representation and leadership. Examining the representation of women in clinical trial leadership may help to inform and enable the design of targeted interventions and policies to foster a more inclusive and diverse environment in clinical trial leadership.

Total Knee Arthroplasty After Meniscectomy Is More Likely in Patients With Bicompartmental or Complex Tears.

Purpose: To determine the relationship between meniscus tear morphologies, stratified by location and pattern, and knee arthroplasty rates in a commercial insurance population.

Methods: The PearlDiver database was queried for patients ≥35 years old with a meniscus tear of specified laterality and ≥2 years follow-up between 2015 and 2018. Two analyses were conducted with cohorts matched on age, sex, Charlson Comorbidity Index, obesity, osteoarthritis (OA), and treatment (meniscectomy vs conservative): one with equal-sized subgroups by tear location (medial only, lateral only, or both medial and lateral) and another by tear pattern (bucket-handle, complex, or peripheral).

Patient Demographic Factors Are Not Associated With Mesenchymal Stromal Cell Concentration in Bone Marrow Aspirate Concentrate.

Purpose: To describe the capacity for concentration of a single processing machine for bone marrow aspirate concentrate (BMAC) production and investigate the effects of demographic factors on the number of mesenchymal stromal cells (MSCs) in BMAC.

Methods: Patients enrolled in our institution's randomized control trials involving BMAC who had complete BMAC flow cytometry data were included. Multipotent MSC phenotype, defined as cell-surface coexpression of specific-identifying antigens (≥95% positive) and the absence of hematopoietic lineage markers (≤2% positive), was determined for both patient bone marrow aspirate (BMA) and BMAC samples.

Biomechanical Analysis of Anteroinferior Bankart Repair Anchor Types.

Background: All-suture anchors and knotless anchors are increasingly used in the repair of anteroinferior labral tears in patients with shoulder instability. Optimal repair constructs may limit recurrent instability.

Purpose: To perform a quantitative biomechanical comparison of 3 labral fixation devices for soft tissue Bankart lesions: knotless soft-body tensionable anchor (SB knotless), knotted soft-body anchor (SB knotted), and knotless hard-body PEEK (polyether ether ketone) interference anchor (HB knotless).

Establishing the Minimal Clinically Important Difference and Patient Acceptable Symptomatic State following Patellofemoral Inlay Arthroplasty for Visual Analog Scale Pain, Western Ontario and McMaster Universities Arthritis Index, and Lysholm Scores.

Background: The purposes of the study were to define the minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) after patello-femoral inlay arthroplasty (PFA) and to identify factors predictive for the achievement of clinically important outcomes (CIOs).

Methods: A total of 99 patients who underwent PFA between 2009 and 2019 and had a minimum of 2-year postoperative follow-up were enrolled in this retrospective monocentric study. Included patients had a mean age of 44 years (range, 21 to 79).

Association between neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and survival in undifferentiated pleomorphic sarcoma (NLR, PLR, and overall survival in UPS).

Background And Objectives: Cancer-related inflammation has been shown to be a driver of tumor growth and progression, and there has been a recent focus on identifying markers of the inflammatory tumor microenvironment. Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are inflammatory indices that have been identified as prognostic biomarkers in various malignancies. However, there is limited and conflicting data regarding their prognostic value in soft tissue sarcoma (STS) and specifically in undifferentiated pleomorphic sarcoma (UPS).

Long-term outcomes after osteochondral allograft transplantation to the humeral head.

Background: Long-term outcomes of osteochondral allograft (OCA) transplantation to the humeral head have been sparsely reported in the literature.

Purpose: To evaluate outcomes and survivorship of OCA transplantation to the humeral head in patients with osteochondral defects at a minimum of 10 years of follow-up.

Methods: A registry of patients who underwent humeral head OCA transplantation between 2004 and 2012 was reviewed.

Effects of Opioid-Limiting Legislation and Increased Provider Awareness on Postoperative Opioid Use and Complications After Hip Arthroscopy.

Background: On August 31, 2017, Ohio passed legislation that regulates how opioids can be prescribed postoperatively. Studies have shown that such legislation is successful in reducing the morphine milligram equivalents (MMEs) prescribed after certain orthopaedic procedures.

Purpose: (1) To determine if the opioid prescription-limiting legislation in Ohio reduced the cumulative MMEs prescribed after hip arthroscopy without significantly affecting the rates of emergency department (ED) visits, hospital readmissions, and reoperations within 90 days postoperatively, and (2) to assess risk factors associated with increased postoperative opioid dosing.

Hip Capsular Reconstruction With Indirect Head of the Rectus Femoris Tendon.

Hip capsulotomy is performed during arthroscopic hip procedures to achieve adequate visualization of the joint and instrument access. The hip capsule, and in particular the iliofemoral ligament, is an important stabilizer of the hip joint, and patients who undergo capsulotomy without subsequent repair may experience hip pain and instability, with increased risk of requiring revision hip arthroscopy. Therefore, restoring watertight closure of the capsule is necessary to restore native biomechanics and achieve desired postoperative outcomes.

Forearm Pronation at Foot Contact: A Biomechanical Motion-Capture Analysis in High School and Professional Pitchers.

Background: It has previously been speculated that baseball pitchers who display excessive forearm pronation at foot contact (FC) have a higher propensity toward ulnar collateral ligament injury and subsequent surgery.

Purpose: To evaluate the association between degree of forearm pronation/supination at FC and throwing arm kinetics in high school and professional pitchers, at both the individual (intrapitcher) and the group (interpitcher) level.

Study Design: Descriptive laboratory study.

Background: Social media has the potential to act as an avenue for patient recruitment, patient and surgeon education, and expansion of the physician-patient relationship.

Purpose: To evaluate the existing social media presence among members of the American Orthopaedic Society for Sports Medicine (AOSSM) to describe trends in different subgroups within the membership.

Study Design: Cross-sectional study.

Patient-Specific Variables Associated with Failure to Achieve Clinically Significant Outcomes After Meniscal Allograft Transplantation at Minimum 5 Year Follow-Up.

Purpose: To determine the improvements in patient-reported outcome measures (PROMs) necessary to achieve minimal clinically important difference (MCID), patient-acceptable symptomatic state (PASS), and substantial clinical benefit (SCB) after primary meniscal allograft transplantation (MAT) at a minimum of 5-year follow-up, while identifying variables predictive of achieving clinically significant outcomes (CSOs).

Methods: A retrospective review was performed to identify patients undergoing primary MAT at a single institution from 1999 to 2016. Lysholm, International Knee Documentation Committee (IKDC), and Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales were collected before surgery and at a minimum of 5-year follow-up.

Spanish-Speaking Patients Have Limited Access Scheduling Outpatient Orthopaedic Appointments Compared With English-Speaking Patients Across the United States.

Purpose: To evaluate whether Spanish-speaking patients can obtain appointments to outpatient orthopaedic surgery clinics across the United States at a similar rate as English-speaking patients and to examine the language interpretation services available at those clinics.

Methods: Orthopaedic offices nationwide were called by a bilingual investigator to request an appointment with a pre-established script. The investigators called in English asking for an appointment for an English-speaking patient (English-English), called in English requesting an appointment for a Spanish-speaking patient (English-Spanish), and called in Spanish asking for an appointment for a Spanish-speaking patient (Spanish-Spanish) in a random order.

The reverse fragility index: RCTs reporting non-significant differences in failure rates between hamstring and bone-patellar tendon-bone autografts have fragile results.

Purpose: The reverse fragility index (RFI) is a novel metric to appraise the results of studies reporting statistically non-significant results. The purpose of this study was to determine the statistical robustness of randomized controlled trials (RCTs) reporting non-significant differences in anterior cruciate ligament reconstruction (ACLR) graft failure rates, defined as re-rupture/revision ACLR rate, between hamstring tendon (HT) and bone-patellar tendon-bone (BTB) autografts by calculating RFIs.

Methods: A systematic review was performed to identify RCTs that compared HT to BTB grafts for ACLR through January 2022.

Biokinetic Evaluation of Hallux Valgus during Gait: A Systematic Review.

Background: Foot pathologies can affect the kinetic chain during gait, leading to altered loading at other joints that can lead to subsequent pathologies. Although hallux valgus is the most common foot disease, little has been discussed about the biokinetic effects of hallux valgus on the foot and lower limb. This systematic review evaluated the kinematic, kinetic, and pedobarographic changes of the hallux valgus foot compared to a healthy one.

Determining the Time Required to Achieve Clinically Significant Outcomes on the PROMIS Upper Extremity Questionnaire After Arthroscopic Rotator Cuff Repair.

Background: Clinically significant outcome (CSO) thresholds for the Patient-Reported Outcome Measurement Information System-Upper Extremity (PROMIS-UE) score have been previously defined after arthroscopic rotator cuff repair (RCR). However, the time required to achieve CSOs for the PROMIS-UE score is unknown.

Purpose: To (1) determine the time required to achieve the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and Patient Acceptable Symptom State (PASS) score thresholds after RCR for the PROMIS-UE questionnaire and (2) identify patient factors associated with earlier or delayed achievement of these clinical benchmarks.

Revision Lateral Femoral Condyle Osteochondral Allograft Transplantation With the Snowman Technique After Failed Previous Oblong Osteochondral Allograft.

Osteochondral allograft transplantation provides components of both cartilage and subchondral bone and can be used in large and multifocal defects where autologous procedures are limited by donor-site morbidity. Osteochondral allograft transplantation is particularly appealing in the management of failed cartilage repair, as larger defects and subchondral bone involvement are often present, and the use of multiple overlapping plugs might be considered. The described technique provides our preoperative workup and reproducible surgical approach for patients who have undergone previous osteochondral transplantation with graft failure and are young, active patients who would not be otherwise suited for a knee arthroplasty procedure.

Nonoperative Treatment of the Biceps-Labral Complex.

The long head of the biceps and superior labrum should be evaluated as an interdependent functional unit. A focused patient history and physical examination including multiple provocative tests should be performed alongside advanced imaging studies to obtain an accurate diagnosis. Nonoperative treatment modalities including nonsteroidal anti-inflammatory drugs, glucocorticoid injections, and a standardized physical therapy regimen should be exhausted before operative intervention.
