Summary
Objectives: To describe the complications, short and long-term outcome and owner satisfaction
of dogs with cranial cruciate ligament rupture treated with a recently described new
osteotomy for the modified Maquet technique (N-MMT).
Materials and methods: Medical records and radiographs of 82 dogs (84 stifles) were reviewed. Details regarding
short-term outcome and complications were recorded from the medical records. Long-term
follow-up information was obtained by telephone interview. Historical data and complications
were statistically analysed.
Results: Major complications occurred in 34/84 stifles. Intra-operative complications occurred
in 26/84 stifles, all of which were fissures or fractures of the cortical hinge. Twenty-one
of these fractures or fissures were repaired with a figure-of-eight wire. The second
most common major complication was late meniscal tears in 3/84 stifles. One dog sustained
a complete tibial fracture. Non-displaced fracture of the cortical hinge was the most
common postoperative minor complication, which occurred in 5/84 stifles. The median
preoperative lameness score was 3 out of 6. Final in-hospital re-evaluation of limb
function was available in 58 dogs. The median lameness score at that time was 0 out
of 6. Development of osteotomy related complications was not associated with a significant
change in the postoperative lameness score.
Clinical significance: Subjectively assessed clinical outcome with the N-MMT was good to excellent in this
cohort of dogs. However, a high rate of intra- and postoperative complications of
the N-MMT procedure was also present in these dogs.
