Patellar Height Correlates Modestly With Trochlear Dysplasia: A Magnetic Resonance Imaging Analysis.

Purpose: To evaluate whether there is a correlation between the position of the patella and trochlear morphology in patients with and without patellar instability using exclusively MRI measurements.

Methods: MRI scans of knees in patients with patellofemoral instability and knees of patients with an ACL (anterior cruciate ligament) tear as a control group were reviewed. Measurements of patellar position (Canton-Deschamps ratio, Patellar Trochlear Index, and lateral patellar inclination) and trochlear morphology (lateral trochlear inclination and sulcus angle) were obtained from each scan.

Clinical outcomes after refixation of subacute repaired distal biceps tendon ruptures.

Background: The aim of this study was to evaluate the clinical outcome and complication spectrum after delayed repair surgery of distal biceps tendon ruptures, postulating that satisfactory results are possible contrary to previous literature.

Methods: Forty-three of 92 patients with a full workup (= OPT in) undergoing primary distal biceps tendon repair were included in this study. The mean age of participants was 49.

Relationship Between Patellar Morphology and Known Anatomic Risk Factors for Patellofemoral Instability.

Background: Patellar instability (PI) is a common problem among pediatric, adolescent, and young adult patients. Recent literature has shown a correlation between pathoanatomy and PI.

Purpose/hypothesis: The purpose of this study was to determine if there is any difference in patellar shape in patients with and without PI and if there is any association between the shape of the patella and the shape of the trochlea.

Glenoid version is associated with different labrum tear patterns in shoulder instability.

Background: Previous studies have evaluated glenoid version as a risk factor for anterior and posterior shoulder instability. However, the association of glenoid version with combined anterior-inferior-posterior (>180°) labrum injuries is unknown. The purpose of the present study was to investigate various parameters of glenoid morphology, including version, in >180° labral tears and to compare these values with isolated anterior and isolated posterior tears.

Incidence and Complications of Open Hip Preservation Surgery: An ABOS Database Review.

Hip preservation surgery encompasses various surgical procedures that have the goal of decreasing the progression of osteoarthritis, preserving normal hip function, and delaying the need for arthroplasty. These procedures can encompass arthroscopic, open, and combined techniques. This study investigated the trends and complications associated with open hip preservation surgery performed by candidates undergoing Part II of the American Board of Orthopaedic Surgery examination.
