Breed, age, weight, and gender were recorded. Radiographs were reviewed for determination of preoperative tibial plateau angle (PreTPA), postoperative TPA (PostTPA), patellar tendon angle (PTA) postoperatively, and TPA at final evaluation (FinalTPA). Difference between PostTPA and FinalTPA was used to define any TPA shift. Radiographic healing at final evaluation was graded based on a 5‐point scale.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Mean time to final recheck was 88 days (range 49–237 days) with mean ± SD PreTPA = 28.6 ± 4.8°; PostTPA = 9.2 ± 2.2°; FinalTPA = 9.7 ± 2.6°; and TPA Shift = 0.52 ± 1.61°. There was no significant difference between PostTPA and FinalTPA (<jats:italic>P</jats:italic> = .084, power > 0.80). Mean postoperative PTA was 89.9 ± 1.7°. There were 2 implant related complications; 1 HCS migration and 1 HCS failure.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>Stabilization of the CBLO using a bone plate augmented with a HCS was effective in maintaining PostTPA and achieving satisfactory radiographic healing.</jats:p></jats:sec>
