Description
Akaraphutiporn and colleagues offer a 2026 radiographic study of medial patellar luxation, a condition where the kneecap slips inward, common in small-breed dogs. Using X-rays of 69 stifle joints from 46 dogs, they compared healthy joints with grade II and grade III luxation. They measured the kneecap and the thigh bone in detail, then calculated ratios describing how well the two parts fit together.
Kneecap size itself did not differ between groups, so the bone alone does not explain the condition. The groove that cradles the kneecap told a different story: grade III joints had a significantly shallower trochlear groove and a wider sulcus angle, signs of progressive flattening. The ratio of kneecap height to groove depth stood out as the most useful measure of mismatch. For surgeons, the message is to plan around the thigh bone's shape rather than the kneecap's size.
