Evidence of subclinical medial collateral ligament injury and posteromedial impingement in professional baseball players.

Background: Recognition and treatment of elbow conditions such as medial collateral ligament injury and posteromedial impingement are increasing in throwing athletes. Magnetic resonance imaging may provide pivotal information in the management of these athletes. Knowledge of the utility of magnetic resonance imaging has become widespread throughout the baseball community.

The split-line pattern of the distal femur: A consideration in the orientation of autologous cartilage grafts.

Purpose: To identify the surface collagen orientations of the distal femur and create a generic cartilage split-line map that could be used as a reference guide for the proper alignment of autogenous cartilage transplants.

Type Of Study: Anatomic, cadaveric study.

Methods: Eight fresh cadaveric knee joints were used to determine the collagen fiber orientation of the superficial layer of the articular cartilage of the distal femur.
