    Objectives Investigation of the association of change in postoperative (post-op) tibial plateau angle (TPA) in dogs with cranial cruciate ligament disease (CCLD) after Tibial Plateau Leveling Osteotomy (TPLO) during six months on the post-op outcome.Methods 60 dogs with CCLD treated with TPLO fulfilled the inclusion criteria. TPA measurements were taken immediately post-op and six months post-op by 3 observers and change in TPA was calculated. Outcome was evaluated with lameness score, owner questionnaire and gait analysis performed preoperatively, and 6-months post-op.Mean change in TPA was 0.22±0.75°. Interobserver reliability for TPA measurements was excellent. No differences for TPA measurements between observers was found (p=0.07-0.105). No association between change of TPA and outcome could be demonstrated. The multivariate linear regression model for the symmetry index of peak vertical force (SIPVF) 6 months post-op was significant (R 2 = 0.210; p = 0.031), and the TPA at 6 months post-op was the only significant factor (ß= 0.459; 95%CI: 0.41 -1.44; p < 0.001, which emphasize a lower TPA 6 months post-op leads to lower SIPVF values.The study indicates that lower TPAs 6 months post-op leads to a more symmetrical gait in hindlimbs 6 months post-op. No other significant factor between post-op changes in TPA and outcome after TPLO was found. Our results show little post-op TPA change up to six months. It might indicate that change in TPA is not present as reported.
