Considerable difference of opinion exists regarding the healing of tendons and tendon grafts. The principle of Roux states that the end result of a transplant in which biologic laws have been observed depends largely on whether or not the functional activity for which the tissue was originally intended has been assumed early. The tension to which the graft should be subjected is also a perplexing problem. The postoperative treatment of tendon grafts differs from that of grafts in other parts of the body, for example, in skin and in bone. With the latter, immobilization is essential in establishing a vascular supply; with the former, immobilization tends to form adhesions which defeat the purpose of the graft.
Until the middle of the eighteenth century, surgeons were largely influenced by the opinions of Galen, who taught that tendons are a mixture of nerves and ligaments the suturing of which is
