Plain-English summary
A group of dogs with knee problems, specifically medial patellar luxation (where the kneecap slips out of place) and cranial cruciate ligament (CCL) disease, underwent a surgical procedure called tibial tuberosity transposition-advancement. After the surgery, most dogs showed improvement, with 29 out of 39 dogs no longer limping just six to eight weeks later, and 35 out of 39 dogs maintained this improvement over several months. However, some dogs did experience complications, including a recurrence of the kneecap issue in a few cases. Overall, this surgery appears to be a promising option for treating these conditions in dogs.

Abstract
OBJECTIVE: To report surgical technique, morphometric effects and clinical outcomes for tibial tuberosity transposition-advancement (TTTA), sulcoplasty and para-patellar fascial imbrication for management of concomitant medial patellar luxation (MPL) and cranial cruciate ligament (CCL) disease in 32 dogs. STUDY DESIGN: Case series. METHODS: A previous technique for tibial tuberosity advancement was modified to incorporate lateral and distal tibial tuberosity transposition. Preoperative, immediate, and six to eight week postoperative radiographs were reviewed with morphometry of a range of tibial and stifle anatomic parameters. Findings of sequential clinical examinations to six to 20 months postoperatively were recorded. RESULTS: Thirty-nine stifles were treated by surgery. Medial patellar luxation grade ranged from II to IV/IV. The CCL rupture was complete in 17/39 stifles, and incomplete in 22/39. Complications occurred in 11/39 stifles including MPL recurrence (n=4). Resolution of subjectively-assessed lameness occurred in 29/39 stifles at the six to eight week assessment. Resolution of lameness was eventually documented in 35/39 stifles (4/39 lost to follow-up), and was maintained at the six to 20 month reassessment where available. The TTTA induced relative patella baja in 31/39 stifles. Magnitude of actual tibial tuberosity advancement was lower than that predicted by cage size. CLINICAL SIGNIFICANCE: Tibial tuberosity transposition-advancement is a potential treatment modality for concomitant CCL disease and MPL in the dog, but refinement of planning is required, while biomechanical and kinematic effects remain unknown.
