Apophysitis of the tibial tubercle, Lannelongue's disease, [1] osteochondrosis of the tibial tubercle [2] Lateral view X-ray of the knee demonstrating fragmentation of the tibial tubercle with overlying soft tissue swelling. Specialty: Orthopedics: Symptoms: Painful bump just below the knee, worse with activity and better with rest [3] Usual onset
The main parameter in this test is step-off, which is the shortest distance from the femur to a hypothetical line that tangents the surface of the tibia from the tibial tuberosity and upwards. Normally, the step-off is approximately 1 cm, but is decreased (Grade I) or even absent (Grade II) or inverse (Grade III) in injuries to the posterior ...
The injury is most commonly treated by open reduction internal fixation as closed reduction is made difficult by the entrapment of the fibula behind the tibia. [1] The entrapment of an intact fibula behind the tibia was described by Ashhurst and Bromer in 1922, who attributed the description of the mechanism of injury to Huguier's 1848 ...
The final step of reconstruction ligament fixation is the proximal tibial attachment of the sMCL. This soft-tissue attachment can be reproduced with a suture anchor [ 28 ] placed 12.2 mm distal to the medial joint line (average location), directly medial to the anterior arm of the semimembranosus tibial attachment.

Tibial tuberosity fractures are infrequent fractures, most common in adolescents. In running and jumping movements, extreme contraction of the knee extensors can result in avulsion fractures of the tuberosity apophysis. [3] A cast is all that is required if the fragment is not displaced from its normal position on the tibia. However, if the ...
This is a pure compression fracture of the lateral or central tibial plateau in which the articular surface of the tibial plateau is depressed and driven into the lateral tibial metaphysis by axial forces.3 A low energy injury, these fractures are more frequent in the 4th and 5th decades of life and individuals with osteoporotic changes in bone.

Bosworth fracture - a fracture with an associated fixed posterior dislocation of the proximal fibular fragment which becomes trapped behind the posterior tibial tubercle. The injury is caused by severe external rotation of the ankle. [4] Volkmann's fracture or Earle's fracture, a fracture of the postero-lateral rim of the distal fibula. [5]
