A Mixed Methods Exploration of Factors That Influence Student Participation in Optional Formative Review Quizzes.

Introduction: Weekly formative Review Quizzes are an integral feature of the Georgetown University School of Medicine assessment program. The Quizzes offer students an opportunity to test themselves in a low-stakes setting and then discuss their answers with peers in small groups; faculty are also present to help the groups with difficult problems.

Methods: We conducted a mixed methods study in which we monitored quiz attendance over the course of the first four curricular blocks, deployed a study specific survey, and held focus groups to determine the factors that influenced quiz participation and how students perceived that the quiz contributed to their learning.

Subtrochanteric femoral shortening for hip centre restoration in complex total hip arthroplasty with functional outcome.

Aims: Complex total hip arthroplasty (THA) with subtrochanteric shortening osteotomy is necessary in conditions other than developmental dysplasia of the hip (DDH) and septic arthritis sequelae with significant proximal femur migration. Our aim was to evaluate the hip centre restoration with THAs in these hips.

Methods: In all, 27 THAs in 25 patients requiring THA with femoral shortening between 2012 and 2019 were assessed.

Biomechanical assessment of an alternative method of staple fixation for anchoring the Bone Patellar Tendon Bone graft to the tibia.

Introduction: The Anterior cruciate ligament (ACL) is the most commonly injured ligament around the knee and is best reconstructed with a biological graft. For ideal graft fixation, there should be sufficient initial strength to avoid failure of fixation and sufficient stiffness to restore the stability of the knee and to avoid gradual loosening in the post-operative period.When considering fixation of Bone Patellar Tendon Bone (BPTB) grafts to the tibia, the interference screw is considered to be the gold standard.
