Influence of Training Background on Elbow Arthroplasty Case Numbers: An Analysis of the American Board of Orthopaedic Surgery Part II Oral Examination Case List Database.

Introduction: This study aimed to evaluate the influence of training background on the frequency and indications of elbow arthroplasty performed by early-career surgeons.

Methods: A review of the American Board of Orthopaedic Surgery Part II Oral Examination Case List database from 2010 to 2021 was completed. The number of cases performed by surgeons from each individual training background were calculated and compared with the total number of surgeons who completed each fellowship during the study period.

Accuracy of MRI in Assessment of High-Grade Partial Distal Biceps Tears.

Background: Magnetic resonance imaging (MRI) is commonly used to diagnose and assess the extent of partial distal biceps injuries. The aim of this study was to report on the accuracy of MRI and the effect of injury history and study timing on its performance.

Methods: A retrospective review of all patients who underwent surgical treatment of partial thickness distal biceps tears at a single center by multiple surgeons was performed.

Clinical Examination in the Diagnosis of Anterior Cruciate Ligament Injury: A Blinded, Cross-sectional Evaluation.

Objective: This study was conducted to compare the effectiveness of clinical tests for anterior cruciate ligament (ACL) injury.

Methods: This study prospectively evaluated the effectiveness of the Lachman test, anterior drawer test, and lever test in diagnosing ACL injury in 133 patients with knee pathology. The examiner was blinded to the patient's history, symptoms, and laterality of the pain at the time of examination.

Clinical Outcomes of Surgical Repair for Partial Distal Biceps Tendon Tears.

Purpose: The purpose of this study was to describe the outcomes of patients treated with surgical repair of partial tears of the distal biceps tendon.

Methods: The study was a retrospective review of repairs of partial tears of the distal biceps tendon performed by multiple surgeons from January 1, 2015 to October 15, 2020. Inclusion criteria consisted of preoperative magnetic resonance imaging indicative of distal biceps pathology without a complete tear and surgical treatment with intraoperative confirmation of a partial tear.

Selective Patella Resurfacing in Contemporary Cruciate Retaining and Substituting Total Knee Arthroplasty: A Matched Cohort Analysis.

Background: Leaving the patella unresurfaced in total knee arthroplasty (TKA) is increasing due to modern patella-friendly implants, awareness that complications are not uncommon with resurfacing, and knowledge that historical studies were scientifically confounded. This study examined the effect of selective patellar resurfacing on patient-reported outcome measures (PROMs) using modern implants and techniques in cohorts rigorously matched for demographics and osteoarthritis severity.

Methods: A total of 166 TKAs performed without patellar resurfacing were case-control matched to 166 TKAs with patella resurfacing.

Primary Repair of Chronic Distal Biceps Tendon Tears.

Background: This study reports the clinical results following primary repair of distal biceps tendon ruptures more 6 weeks after injury.

Methods: A retrospective review of distal biceps tendon repairs performed by 8 different hand surgeons from January 1, 2015 to October 15, 2020 was performed. Patients with complete tears surgically treated ≥6 weeks after injury without tendon graft were included.

Osteoarthritic Severity in Unresurfaced Patellae Does Not Adversely Affect Patient-reported Outcomes in Contemporary Primary TKA.

Introduction: The degree of osteoarthritis (OA) acceptable to leave in a native patella during unresurfaced total knee arthroplasty (TKA) remains unknown. This study's purpose was to examine the effect of patellofemoral OA severity on patient-reported outcome measures (PROMs) in primary TKAs performed without patellar resurfacing.

Methods: One hundred ninety-three primary TKAs performed without patellar resurfacing were retrospectively reviewed.

Reconstruction of the Thumb Metacarpophalangeal Ulnar Collateral Ligament With an Adductor Pollicis Slip: An Anatomic Evaluation.

Purpose: Reconstruction of the ulnar collateral ligament (UCL) of the thumb metacarpophalangeal joint is commonly performed for chronic injuries. This study evaluates the anatomic feasibility of using a part of the adductor pollicis tendon to reconstruct UCL.

Methods: Ten cadaveric arms were dissected to evaluate the relationship between the insertions of UCL and the adductor pollicis.

Use of an Abductor Pollicis Brevis Tendon Slip for Reconstruction of the Radial Collateral Ligament of the Thumb Metacarpophalangeal Joint: An Anatomical Investigation.

Background: Reconstruction of the radial collateral ligament (RCL) of the thumb metacarpophalangeal (MP) joint is commonly performed for chronic injuries. This study aims to evaluate the anatomical feasibility and reliability of using the abductor pollicis brevis (APB) tendon to reconstruct the RCL.

Methods: Ten cadaver arms were dissected to evaluate the relationship between insertions of the RCL and APB.
