Tibial wedge ostectomy: complications of 300 surgical procedures.
BACKGROUND
Tibial wedge ostectomy (TWO) is a surgical procedure that aims to give functional stability during weight-bearing in a hindlimb with cranial cruciate ligament deficiency, by reducing the slope of the tibial plateau angle.


METHODS
Advantages of the TWO surgery are that it does not require dedicated equipment and can be performed in young dogs prior to closure of the physis. However, it is a technically demanding procedure and the potential for complications is high.


RESULTS
In this retrospective review of 249 dogs that had unilateral and 51 that had bilateral TWO surgery, the overall complication rate was 31.7% (95/300) and the rate of revision surgery was considerable (37 cases or 12.33%).


CONCLUSIONS
The most important clinical complications were postoperative medial meniscal tears, tibial fractures and implant failures, necessitating repeat surgery.
