Plain-English summary
A crossbreed dog was brought in because it couldn't put weight on its right back leg and was holding its knee at an awkward angle. The vet found that the dog had a severe case of medial patellar luxation, where the kneecap was slipping out of place. To fix this, the vet performed surgery to rotate the bone structure in the knee, which helped keep the kneecap in the right position. After the surgery, the dog healed well and showed only mild signs of joint wear, allowing it to return to normal activity.

Abstract
A crossbreed dog was presented with non-weight bearing on the right hindlimb and a semi-flexed stifle. Clinical examination and radiographic investigation showed a grade 3 medial patellar luxation, characterised by hypoplasia of the medial trochlear ridge. No other significant skeletal abnormalities were detected. A 180 degrees rotation of the femoral trochlea was the surgical technique chosen to treat the trochlear dysplasia, the aim being to move the normal lateral ridge to the medial side and thereby prevent patellar luxation. This technique was able to restore correct conformation of the femoral trochlea and preserve the integrity of the trochlear groove cartilage, thus potentially retarding the progression of degenerative joint disease. The dog recovered fully and postoperative radiographic examinations showed healing of the rotated trochlea with only mild signs of degenerative joint disease.
