Plain-English summary
A group of dogs with cranial cruciate ligament (CCL) injuries underwent a surgical procedure called a CORA-based leveling osteotomy, which was stabilized using a special bone plate and a headless compression screw. After surgery, the dogs were monitored for an average of about three months, and their knee angles were measured to ensure they remained stable. The results showed that the surgery was effective in maintaining the correct angle of the knee joint, with most dogs healing well. However, there were a couple of complications related to the implants used.

Abstract
OBJECTIVE: To report the effectiveness of a bone plate/headless compression screw (HCS) construct in preventing tibial plateau angle (TPA) shift postoperatively and to describe radiographic healing of the osteotomy. STUDY DESIGN: Case series. ANIMALS: Dogs (n = 31). METHODS: Records of dogs diagnosed with cranial cruciate ligament (CCL) injury treated with the center of rotation of angulation (CORA) based leveling osteotomy (CBLO) stabilized with a bone plate augmented with a HCS were reviewed. 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. RESULTS: 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 (P = .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. CONCLUSION: Stabilization of the CBLO using a bone plate augmented with a HCS was effective in maintaining PostTPA and achieving satisfactory radiographic healing.
