The single antegrade sling graft: a novel hamstring autograft technique for combined anterior cruciate ligament and anterolateral ligament reconstruction.

Introduction: As a result of increased incidence of anterior cruciate ligament (ACL) injury in young athletes, there is a rise in the indications surgical ACL reconstruction procedures. The value of anterolateral ligament (ALL) reconstruction emerges as a proposed solution to prevent graft failures and improve stability in this high demanding category of patients. The purpose of this study is to present our experience with a novel hamstring auto-grafting technique, the single antegrade sling graft (SASG), for combined reconstruction of both ACL and ALL using autologous gracilis (GR) and semitendinosus (ST) grafts utilizing a single femoral tunnel and double tibial tunnels.

Group acceptance sampling plan based on truncated life tests for Type-I heavy-tailed Rayleigh distribution.

This study on the Type-I heavy-tailed Rayleigh (TI-HTR) distribution is a special case of Type-I heavy-tailed (TI-HT) family of distributions was studied. The characteristics were derived, including the moment and its measures, quantile function, reliability measures, and other statistical properties as well as parameter estimation using the maximum likelihood method and penalized likelihood estimation. The behavior of its various functions were shown graphically.
