Outcome and owner assessment after single-session bilateral tibial plateau leveling osteotomy in 127 dogs.

Objective: To retrospectively evaluate complication rates following bilateral tibial plateau leveling osteotomy (TPLO) as well as owner assessment of outcomes and post-operative management.

Methods: Medical records of dogs presenting with bilateral cranial cruciate ligament (CCL) disease that underwent single-session bilateral TPLO from 2015 to 2019 in 1 referral practice were retrospectively reviewed. A non-validated questionnaire was sent to the owners to assess their ability to cope during the rehabilitation period, as well as procedure outcome.

Results: In total, 127 dogs were included for analysis. The overall complication rate was 16.5% (minor complication rate 9.4% and major complication rate 10.2%). Of the 50 owners that answered the questionnaire, 31 (62%) did not need to use sling support at home at any time and 10 (20%) used sling support for < 1 wk. Furthermore, only 1 owner indicated that they would not choose to do a bilateral TPLO surgery again.

Clinical Significance: Bilateral single-session TPLO surgery performed by an experienced surgeon had a similar outcome and complication rate to that of unilateral TPLO surgery. Most owners reported that postoperative care of their dog was not difficult.
