<p>A soft tissue fixation assembly comprises an anchor element which is installed in a bone or other tissue, and a suture joiner element which mates with the anchor element The suture joiner element includes a suture retaining element that securely retains suture, and which is connected to the anchor element. Energy is transmitted through the suture joiner element to cause relative vibratory motion between the respective components and localized collapsing and compressing of the suture joiner element to secure the suture within the suture joiner element and to secure the suture joiner element within the anchor element. The soft tissue segment is thus fixed to the bone via the sutures secured in the bone anchor.</p>
