title: Comparison of complication rates and clinical outcome between tibial plateau leveling osteotomy and a modified cranial closing wedge osteotomy for treatment of cranial cruciate ligament disease in dogs.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  Prospective cohort study.
  
  
  METHODS
  Dogs weighing 20-60 kg with unilateral cranial cruciate ligament disease treated by either TPLO (n = 97) or mCCWO (n = 74).
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
