This study sought to determine if greater flexion when landing with load resulted in knee biomechanics thought to decrease ACL injury risk and whether knee biomechanics during landing relate to knee anatomic metrics. HYPOTHESIS Anatomic metrics regarding the slope and concavity of the tibial plateau will exhibit a significant relation to the increased anterior shear force on the knee and decreased knee flexion posture during landing with body-borne load. STUDY DESIGN Descriptive laboratory study. METHODS Twenty male military personnel completed a drop landing task with 3 load conditions light (~6 kg), medium (15% body weight), and heavy (30% body weight). Participants were divided into groups based on knee flexion exhibited when landing with the heavy load (high- and low-Δflexion). Tibial slopes and depth were measured on weightbearing volumetric isposed to knee forces and biomechanics that load the ACL during weighted landings. CLINICAL RELEVANCE The ability to screen individuals for anatomic metrics that predict knee flexion may identify soldiers and athletes who require additional training to mitigate the risk of lower extremity injury.BACKGROUND Treatment of the severely resorbed maxilla traditionally has been managed with such protocols as sinus elevation, bone and soft-tissue grafting, and osteotomy procedures. The use of zygomatic implants has made it possible to circumvent such procedures, allowing immediate loading of implants with fixed prostheses. OBJECTIVE This study reports the success rate of 452 zygomatic implants placed and restored in 249 patients over 5 years in a multi-center setting. Additionally, case examples are presented. METHODS The authors conducted a multi-center case series study. Inclusion criteria were ASA 1 or ASA 2, nonsmo
