Background And Purpose: The prevalence of arm pain in youth baseball players is high with approximately half reporting arm pain during the season, and the number of ulnar collateral ligament reconstructions in youth baseball players is increasing. Few studies have examined the relationship between shoulder strength and passive range of motion (ROM) with arm pain (either shoulder or elbow pain) during throwing, especially in athletes in early adolescence. The purpose of this study was to determine the relationship between shoulder ROM and strength and the presence of arm pain during throwing in youth baseball players.

Foot strike pattern has been shown to influence VLR while running, but little is known about its influence on PFA. Twenty healthy women ran on a treadmill for 2 conditions: with a rearfoot strike and with a forefoot strike.

- The study explores the anatomic and biomechanical aspects of the indirect head of the rectus femoris (IHRF) tendon as a graft for labral reconstruction, focusing on its anatomical relationships and relevance in surgery.
- Researchers performed cadaveric tests to assess IHRF's effectiveness in restoring joint function, comparing its performance against the iliotibial band (ITB) while also evaluating the potential complications from harvesting the graft.
- Results highlighted specific anatomical measurements related to the IHRF's attachment points and demonstrated that IHRF may be a viable option for labral reconstruction, with detailed radiographic and contact pressure data supporting its use.
Hip and Pelvis Movement Patterns in Patients With Femoroacetabular Impingement Syndrome Differ From Controls and Change After Hip Arthroscopy During a Step-Down Pivot-Turn Task.

February 2024
Background: Alterations in hip kinematics during functional tasks occur in positions that cause anterior impingement in patients with femoroacetabular impingement (FAI) syndrome. However, tasks that do not promote motions of symptomatic hip impingement remain understudied.
Purpose: To compare movement patterns of the hip and pelvis during a step-down pivot-turn task between patients with FAI and controls as well as in patients with FAI before and after hip arthroscopy.
