Plain-English summary
A group of 82 dogs with torn knee ligaments underwent a surgical procedure called tibial tuberosity advancement (TTA) to help stabilize their knees. Half of the dogs received a new type of bone graft made from bovine tissue, while the other half had their own bone grafts used. After eight weeks, both groups showed similar healing in the surgery area, but the dogs with their own bone grafts had better healing at the top part of the surgery site. Overall, both treatments were effective, but using the dog's own bone may provide some advantages in certain areas of healing.

Abstract
OBJECTIVE: To compare radiographic healing and clinical outcome of a frontal-opening wedge osteotomy of canine tibiae when the osteotomy site is packed with either a novel bovine xenograft or standard autogenous cancellous bone graft (ACBG). STUDY DESIGN: Cohort study. ANIMALS: Dogs (n = 82) with partial or complete rupture of the cranial cruciate ligament that had tibial tuberosity advancement (TTA). METHODS: In 48 dogs, the osteotomy was packed with a novel bovine xenograft and in 34 dogs, ACBG was used. Eight week postoperative radiographs from both groups were graded for osteotomy healing using a 0-4-point scale. Data were analyzed using a Mann-Whitney test with significance set at P < .05. RESULTS: Thirty-four dogs (39 stifles) with xenoimplants had complete records and radiographic follow-up at 8 weeks. No significant differences between xenografting and autografting were identified in grading of osteotomy fill, osteointegration, or healing of the distal osteotomy. Significant differences were noted in grading of osteotomy healing proximally (autograft > xenoimplant) and of opacity in the osteotomy site (xenoimplant > autograft). CONCLUSIONS: Radiographic evidence of healing of the xenoimplanted portion of the TTA osteotomy was equivalent to results with ACBG. Healing of the proximal osteotomy site (above the cage) was improved when ACBG was used as the graft.
