Labelling of lesions in the stifle joint. a Pig 3. An osteochondrosis lesion is labelled yellow in the lateral femoral condyle, and a cyst-like osteochondrosis lesion is labelled green in the medial femoral condyle. b Pig 4. A cyst-like lesion is labelled red in the medial trochlear ridge. c Pig 26. There is an osteochondrosis lesion at the extensor fossa that was labelled blue and grouped with lateral trochlear lesions, and osteochondrosis lesions labelled in yellow in the lateral and green in the medial condyle, respectively. d Pig 21. The arrow points to a large, cyst-like lesion immediately deep to the intercondylar eminences of the tibia that is not labelled because the labelling application did not include any tibial regions. There is also a small osteochondrosis lesion labelled green in the medial femoral condyle
