To report complication rates and clinical outcomes after tibial plateau leveling osteotomy (TPLO) and a modified cranial closing wedge osteotomy (mCCWO) for treatment of cranial cruciate ligament disease in dogs.
Prospective cohort study.
Dogs weighing 20–60 kg with unilateral cranial cruciate ligament disease treated by either TPLO (n = 97) or mCCWO (n = 74).
Clinical and radiographic assessments including lameness score, morphometric measurements and tibial plateau angle (TPA) were made before surgery and 8 weeks after either TPLO or mCCWO. Long-term outcome assessment by owner questionnaire or interview was undertaken at ≥6 months postoperatively.
Significant differences in lameness scores between groups were not identified at short- or long-term follow-up. Major complication and reoperation rates did not differ significantly between groups (TPLO 7.2% and 6.1%; mCCWO 9.5% and 5.4%). Median postoperative TPA did not differ significantly between groups (TPLO group 5.5°; mCCWO group 6.5°). At >6 months owner assessed lameness, disability, quality of life and satisfaction were not different between groups and were good in 90–97% of dogs.
In dogs weighing 20–60 kg, TPLO and mCCWO are associated with similar complication rates and clinical outcomes when performed by surgeons experienced with the surgical techniques.
