Fracture characteristics | Management | Fracture types | Management | |
---|---|---|---|---|
 < 0.5 cm, extra-articular, or avulsion fracture | Conservative | Pointy | Undisplaced | Conservative |
 < 0.5 cm, displaced, intra-articular | Arthroscopic excision |  | Displaced | Excision |
0.5–1 cm, displaced | Arthroscopic assessment of chondral lesion | Flat | Follow the management strategy for fracture characteristics described above |  |
 > 1 cm single fragment | Arthroscopic assisted screw fixation | Neck-like | Displaced neck is too thin to fixed | Excision |
 > 1 cm or multiple segmental fractures, or comminuted fractures, or fractures with dislocation | Emergency reduction, open reduction and internal fixation |  | Others | Follow the management strategy for fracture characteristics described above |
