From: Patellar development after patella instability and early reduction in growing rabbits
Gross anatomy of the patella: 5 months after release surgery of the non-reduced group (left), 5 months after release surgery of the control group (middle), 5 months after release surgery of the reduction group (right). The articular surfaces of all three groups were smooth. However, the articular surface of the patella was flatter in the non-reduced group (left) than in the control group (middle) and the reduction group (right). The transverse diameter of the patella was longer in the non-reduced group (left) than in the control group (middle) and the reduction group (right)
