Plain-English summary
A group of 14 dogs with medial patellar luxation (where the kneecap slips out of place) and patella alta (where the kneecap is positioned too high) underwent a new type of surgery to help fix the problem. The modified procedure involved repositioning the tibial crest to better align the kneecap, which showed promising results. After the surgery, the dogs experienced favorable outcomes, with fewer complications than traditional methods. This approach could become a standard treatment for dogs facing this issue, helping them regain normal knee function.

Abstract
Medial patellar luxation is defined as medial displacement of the patella from the trochlear groove. In dogs, medial luxations account for 75% of all patellar luxation cases, and are frequently associated with patella alta. Common surgical treatments for medial luxation are trochleoplasty and lateral transposition of the crest to drive the patella into the correct anatomical alignment. Postoperative complications for this procedure are estimated to be between 18-29% of cases, with up to 48% of complications involving reluxation. It was previously hypothesized that in cases of medial luxation involving patella alta, the addition of a distal component to the lateral tibial crest transposition will result in repositioning of the patella into its proper position in the trochlear groove, thus reducing the recurrence of luxation. We performed this modified procedure on 14 dogs (17 limbs) that were suffering from medial luxation combined with patella alta, and our results led to favourable clinical outcomes. This modified surgical procedure places the patella into a more normal proximo-distal anatomical position, is simple to perform, and may become common practice for surgical treatment of medial patellar luxation with an alta component.
