Background: Tibial plateau levelling osteotomy (TPLO) is commonly used to manage cranial cruciate ligament (CrCL) disease. The use of a spherical osteotomy blade (S‐TPLO) enables correction of some tibial deformities with three rotational degrees of freedom. Methods: As a proof of concept, this retrospective study included 45 dogs with CrCL disease that were treated with an S‐TPLO. The tibial plateau angle (TPA) was measured preoperatively, immediately after surgery (pTPA 0 ) and on postoperative days 42 (pTPA 42 ) and 56 (pTPA 56 ). Lameness and osteotomy healing were assessed until 56 days postoperatively. Results: Thirty‐one dogs had complete CrCL ruptures, and 14 dogs had partial ruptures. Thirty‐one dogs had medial meniscal damage. The mean TPA, pTPA 0 , pTPA 42 and pTPA 56 were 26.0°, 7.8°, 8.5° and 8.9°, respectively. The TPA from post‐op to follow‐up did not vary significantly (p > 1.365). Minor complications occurred in five dogs. The mean lameness score improved significantly from 3.2 preoperatively to 0.9 on day 56 (p < 0.0001). The mean healing score improved significantly from 1.6 on day 42 to 2.2 on day 56 (p < 0.001). Conclusion: S‐TPLO was successful in treating CrCL disease in stifle joints without tibial deformities, with results comparable to previously reported TPLO outcomes.
