An improved device provides a cost-effective, time-effective way to stably and reliably affix soft tissues (e.g., tendon or ligament) to the surface of anatomical structures with comparable or greater strength and stiffness (e.g., bone). The device does not require specialized procedures or tools. A single device applies both incremental tensioning and compression to the soft tissue being affixed. The device allows the user, typically a physician or veterinarian, to reliably manipulate, control, and maintain tissue tension. The device is versatile, and can accommodate attachment of soft tissues of different sizes and mechanical properties to bone or to other soft tissues. These features provide flexibility to human and veterinary health practitioners in a variety of specialized areas including orthopedics, joint stabilization, soft tissue repair, spinal surgery, and plastic surgery.
