Surgical advances in the management of cranial cruciate disease at Henley House VetsJune 29, 2020
Rupture of the cranial cruciate ligament (CCL) is a common injury in dogs, and sometimes cats. It occurs when the ligament is put under severe strain due to twisting or overstretching or when the ligament degenerates and loses strength over time. Once the ligament is ruptured it creates instability in the stifle (knee joint) which lead to rapidly progressing osteoarthritis.
Until recently, the preferred method of stabilisation was to arrange referral to an orthopaedic specialist to perform a TPLO (Tibial Plateau Levelling Osteotomy) where the top of the shin bone (tibia) is cut and rotated to alter the angle at which it meets the femur (thigh bone). This procedure has good results, especially for bigger dogs, but is very expensive and is performed in unfamiliar surroundings by a vet you have not met before.
At Henley House we are now able to perform the MMP (Modified Maquet Procedure) which gives similar results to the TPLO even in larger dogs but can be performed here by head vet, Chris Hall.
The MMP procedure involves a cut (osteotomy) in the tibia allowing the tibial tuberosity to be hinged forwards and held in place by a wedge-shaped implant made from titanium foam. This change of angle puts tension on the patella tendon (kneecap) and helps to reduce the instability caused by loss of the CCL.
As a result, dogs who have had this procedure are often using the affected limb after only a few days. Strict, controlled rest is still very important during the following 2-3 months while the patient’s bone merges with that of the titanium foam implant.
This has been a very popular and successful technique used around the world and results so far at Henley House have been very encouraging.
If your dog has a persistent, unilateral hind limb lameness call the surgery on 01825 766099 to arrange an appointment with Chris to discuss your options.
