Short-term and eight to 12 months results of a tibial tuberosity advancement as treatment of canine cranial cruciate ligament damage.
OBJECTIVE
To describe the perioperative complications and the six weeks and eight to 12 months outcome of cases of canine cranial cruciate ligament damage treated with a tibial tuberosity advancement.


METHODS
The medical records including the six weeks' postoperative re-evaluation and radiographs of dogs with a tibial tuberosity advancement (70 operated stifles) were analysed regarding the short-term outcome and the recorded complications. A questionnaire for the evaluation of the eight to 12 months outcome was sent to the owners and the answers tabulated.


RESULTS
The complication rate was comparable with previous reports of cranial cruciate ligament rupture treated with a tibial tuberosity advancement or a tibial plateau leveling osteotomy (TPLO). The most frequent complication was a symptomatic late secondary meniscal damage in six cases (8.5 per cent). These cases were successfully treated with a partial meniscectomy during a minimal invasive procedure. The six-week re-evaluation showed advanced healing of the tibial crest osteotomies in 94 per cent of the cases and a significant reduction of the lameness in all dogs. Eighty-three per cent of the owners reported that their dogs are never lame or only after heavy exercise eight to 12 months after the tibial tuberosity advancement procedure. Sixty-five per cent of the owners stated the overall treatment to be excellent, 28 per cent good.


CONCLUSIONS
The six weeks' follow-up examination and the questionnaire revealed results of the tibial tuberosity advancement comparable to previously published studies, stating that the lameness and the activity level of the patients with cranial cruciate ligament disease greatly improved after the tibial tuberosity advancement.
