A fastener (30,130) is provided for securing a soft tissue (4) to a bone (6) upon actuation of an actuating mechanism (16,116). The fastener (30,130) includes an elongated tubular shaft (32,132) having first and second opposing ends (34,36; 134,136), an aperture (38,138) extending from the second end (36,136) toward the first end (34,134), and a collar (40,140) disposed at or about the second end (36,136). The first end (34,134) of the elongated tubular shaft (32,132) is inserted through the soft tissue (4), through the exterior surface (10) of the cortex (8) and into the interior (12) of the bone (6). The collar (40,140) engages and secures the soft tissue (4). In response to being actuated by the actuating mechanism (16,116), a portion (34,134) of the elongated tubular shaft (32,132) deforms against the cortex (8) within the bone (6), thereby securing the soft tissue (4) between the collar (40,140) and the exterior surface (10) of the cortex (8) of the bone (6). A tissue fastener system (2,102) and an associated method of fastening soft tissue (4) to a bone (6) are also disclosed.
