Osteochondral Fractures of the Patella



- See:
      - bipartite patella
      - pediatric avulsion fractures
      - patellar dislocation

- Discussion:
    - are primarily of two types;
    - direct blow, or more commonly patellar dislocation, may cause an immediate frx around the point of contact, separating a single fragment 
           that includes articular cartilage, subchondral bone, and supporting trabecular bone.
    - this piece may never displace, and in this case fracture usually heals with time and causes little trouble;
    - however, fragment may displace and become a mechanically troublesome loose body;
    - excision has been recommended in these situations but, for large fragments, stabilization by transosseous fixation with Herbert screw has 
         been described.
