Plain-English summary
A group of dogs with congenital medial patellar luxation (a condition where the kneecap dislocates) underwent surgery, and many were found to have significant cartilage erosion on the surface of their kneecaps. In fact, two-thirds of the dogs showed some level of erosion, with the damage being most severe in heavier dogs and those with the most severe luxation. This erosion could be a reason why some dogs continue to have problems even after surgery. Understanding this issue can help veterinarians better manage expectations and treatment plans for affected dogs.

Abstract
One hundred and forty-five stifles of client-owned dogs that underwent corrective surgery for congenital medial patellar luxation were inspected for cartilage erosion on the articular surface of the patella. The lesions were mapped in surface percentage ranges of 20% and by location. Two-thirds of the patellae had cartilage erosion. Cartilage erosion varied between 0 and 100% of the total patellar articular surface and was localised mainly on the medial and distal side of the patella. Dogs with Grade IV patellar luxations and heavier dogs were more affected. The majority of dogs in our study with congenital medial patellar luxation had grossly apparent cartilage erosion on the articular surface of the patella, which may help to explain why certain patients do not function well clinically after technically successful corrective surgery.
