Dandelion is a 3-year-old English Mastiff. In September 2014, she became lame on her right hind limb and was treated with a course of anti-inflammatories. After 2 courses with no improvement, Dandelion was scheduled to have her knee examined by Dr Dennis Choi (Mount Pleasant Veterinary Centre, Gelenggang) under general anaesthesia.
Upon examination, there was an instability of her knee reflected by a positive cranial drawer test. This confirmed a cranial cruciate ligament rupture.
Dandie’s surgery, performed by Dr Choi, is called a cranial tibial wedge osteotomy. A triangular wedge of bone is cut from the tibia to change the angle of the weight bearing surface of the knee. This prevents abnormal sliding motion of the joint which occurs after the cruciate ligament has ruptured.
By the first week, Dandie was able to place weight on her right hind leg but still visibly lame. 2 weeks after surgery, she was feeling better and to my dismay, trying to run and jump. Activity had to be restricted for a full 12 weeks until bone healing was complete. Premature, uncontrolled activity can risk breakdown of the surgical implant.
A seroma (sterile accumulation of fluid), almost the size of a fist, had also developed at her surgical site. No specific treatment was required for the seroma and it was resorbed by her body in about three weeks.
Dandelion has since made a full recovery from surgery and is back to her mischievous self – jumping onto sofas, stealing random items from the garden and chasing birds every morning!
