Plain-English summary
A group of 45 dogs with cranial cruciate ligament (CrCL) disease underwent a new surgical technique called spherical tibial plateau levelling osteotomy (S-TPLO). This method was used to correct knee issues and improve their mobility. After surgery, the dogs showed significant improvement in lameness, going from a score of 3.2 before surgery to just 0.9 by day 56. Most dogs healed well, and while a few had minor complications, the overall results were promising, similar to traditional TPLO surgery outcomes.

Abstract
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) and on postoperative days 42 (pTPA) and 56 (pTPA). 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, pTPAand pTPAwere 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.
