We take pride in being able to perform most surgeries here in Middleton Cheney. Here’s a video of John performing a cruciate repair:
The cruciate ligament in the stifle (knee) prevents the lower part of the leg (tibia) sliding backwards and forwards in relation to the upper part of the leg (femur). Rupture tends to occur when the stifle is put under enormous strain, such as when a running dog suddenly changes direction. Genetics plays a large role too; almost half of dogs that rupture one cruciate ligament will go on to rupture the other in the opposite stifle.
The procedure on the video uses a porous titanium wedge to move the front of the tibia (which is attached to the patellar ligament) forward. By moving this forward we neutralise the forces within the stifle that causes the painful sliding motion. The cruciate ligament itself isn’t repaired; it’s just not needed any more. We expect 90% of dogs to return to full and normal life with appropriate aftercare.
