Gross anatomy of the femoral trochlea. a1 Sham group (SG) at 3 weeks postoperatively. a2 SG at 6 weeks postoperatively. b1 Patellar hypermobility group (PHG) at 3 weeks postoperatively. b2 PHG at 6 weeks postoperatively. c1 Patellar dislocation group (PDG) at 3 weeks postoperatively. c2 PDG at 6 weeks postoperatively. At 3 weeks postoperatively, the femoral trochlea was blunter in the PHG and PDG compared with the SG. At 6 weeks postoperatively, the trochlea groove was shallower in the PHG and PDG than the SG. At 6 weeks postoperatively, there was cartilage accumulation on the bilateral condyles in the PHG, and on the lateral condyle of the PDG
