An acute tear of the ligament generally heals conservatively. Whereas, it is thought that the tear of the anterior cruciate ligament (ACL) does not heal by the conservative treatment. There are many studies about the factors that ACL does not heal conservatively. The purpose of the research was to create a rat model of natural healing of ACL and to examine the healed ligament histologically and mechanically. After cutting ACL, the artificial ligament was penetrated the bone tunnel of tibia tuberosity and back of the distal femur, and controlled the abnormal movement of the knee joint. We had confirmed the continuity of the healed ACL in all rats with histological evaluation. Running of the healing ligament had been normally approximated. Compared to the normal ACL, the healing ligament was thick, and scar tissue had grown into joint intercondylar fossa. Healing ACL was about half strength compared to the normal. We found that the ruptured anterior cruciate ligament was healed by joint control kinematically.
