Cruciate Ligament Disease & Tibial Tuberosity Advancement

dvm (54)Anterior cruciate ligament (ACL) rupture is one of the most common orthopaedic conditions we diagnose and treat at the clinic.  As in people (AFL players in particular), ACL rupture is an extremely painful and debilitating injury, and if left untreated can lead to long term suffering in the form of severe osteoarthritis.

Tibial plateau leveling procedures are a recent technique that addresses the problem of tibial conformation abnormalities (large tibial plateau angle).  Various procedures are now available that include TPLO (Tibial Plateau Levelling Osteotomy), TTO (Triple Tibial Osteotomy) and TTA (Tibial Tuberosity Advancement) These techniques involve cutting the tibia and applying a bone plate resulting in a reduced tibial plateau angle. This provides excellent results in dogs weighing over 15kg.

Currently we are performing TTA (Tibial Tuberosity Advancement). This procedure involves cutting the tibial tuberosity and advancing it forward so that the patella tendon is perpendicular to the slope of the tibial plateau.  This prevents the abnormal sliding motion of the joint which occurs after the ligament has been damaged.  This procedure relieves the pressure of the injured cruciate ligament and  stabilizes the joint, resulting in a reduction in arthritis. Compared with other tibial plateau leveling procedures, the TTA is less invasive, as there is less soft tissue dissection during surgery and the bone is cut in a portion that does not bear the body's weight.  This results in less swelling and pain following surgery.  In general lameness resolves more rapidly following TTA.  Finally, TTA implants are made from titanium, which offers superior biocompatibility.
