Biceps tenodesis is a commonly performed procedure. It can be done using a multitude of fixation methods, at multiple locations, and either open or arthroscopic, with little if any clinical differences in the literature. Yet, many techniques have drawbacks in the risk of complications or in the technical ease. Here we present what we have found to be an efficient, simple, reproducible technique: KAToB, Knotless All-arthroscopic intraarticular Tenodesis of the Biceps using a knotless anchor at the articular margin. This technique minimizes the risk of nerve injury, infection, and fracture; has good clinical outcomes; and has a low rate of failure.
