Cranial Cruciate Ligament (CCL or CrCL) Rupture Repair

Your dog’s cranial cruciate ligament (CCL) is located in the canine knee joint and is responsible for providing stability to the joint. When your pet injures their CCL, it is the equivalent of a human injuring their anterior cruciate ligament (ACL).

Injuries to the CCL / ACL are often due to variety of factors, including aging (degeneration) of the ligament, being overweight, genetics, being out of condition, or the result of an accident such as landing wrong, twisting or slipping. Dogs are also more prone to CCL injuries if they have already had one in another leg.

There are many ways to repair a cranial cruciate ligament.
Ask us about our state of the art techniques: TPLO, TTA, TTO, MMP, CBLO, FHT, and Lateral Imbrication. CCL surgery for dogs starts at only $1000.

Our CCL / ACL Ligament Rupture Repair Techniques

Tibial Plateau Leveling Osteotomy (TPLO)

Developed by Dr. Slocum in Eugene, Oregon, (he is not board certified) after having the medial meniscus inspected for damage. The tibial plateau, including the joint surface, is then rotated from its backward sloping postion to a level position. This is done by an oscillating curved bone saw blade, rotating the cut portion, and placing a bone plate to hold the rotated portion in its new orientation while the bone heals. This change in geometry leads to redistribution of forces in the joint which neutralizes cranial tibial thrust. Therefore, the joint, does not depend on the CrCL for stability, replacing the ligament is now unnecessary.

Tibial Tuberosity Advancement (TTA)

TTA was developed by Dr. Tepic in Zurch Switzerland (who is not board certified), and was taught by KYON Pharma. KYON Pharma is not affiliated or recognized by the American Veterinary Medical Association (AVMA) or FDA, and KYON certification is not a Board certification.

The TTA is a dynamic technique. It is the state-of-the-art bio-mechanical study of the canine stifle joint. With TTA, the tibial tuberosity is cut and then advanced forward leading to redirection of the straight patellar ligament. This change in Geometry results in redistribution of the forces within the stifle joint, cranial tibial thrust is neutralized and replacement of the torn CrCL is unnecessary.

Triple Tibial Osteotomy (TTO)

Developed by Dr. W. Bruce in Australia (who is not board certified) TTO is the newest of the dynamic stabilization techniques. Similar to TPLO and TTA, it involves cutting and rearranging bone in the vicinity of the top or the tibia in order to effect a bio-mechanical change in the CrCL-deficient limb to eliminate cranial tibial thrust and provide stability without replacing the torn ligament. This newest technique, in theory, makes use of the positive aspects of both the TPLO and TTA while better controlling the possible draw backs.
