OSD may result in an avulsion fracture, with the tibial tuberosity separating from the tibia (usually remaining connected to a tendon or ligament). This injury is uncommon because there are mechanisms that prevent strong muscles from doing damage. The fracture on the tibial tuberosity can be a complete or incomplete break. [citation needed]
The tibial tuberosity thus forms the terminal part of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when the foot strikes the ground. [1] The two ligaments, the patella, and the tibial tuberosity are all superficial, easily palpable structures. [2]
X-ray of a 15-year-old male, showing an older avulsion fracture of the tibial tuberosity. A tibial tuberosity avulsion fracture is an incomplete or complete separation of the tibial tuberosity from the tibia. This occurs as a result of a violent contraction of the quadriceps muscles, most often as a result of a high-power jump. Incomplete ...
Patellar tendon rupture showing a marked distance between the tibial tuberosity and the bottom of the knee cap. Specialty: Orthopedics: Symptoms: Pain, trouble walking, inability to straighten the knee [1] Usual onset: Sudden [2] Types: Partial, complete [1] Causes: Falling directly on the knee, jumping from a height [1] Risk factors
“Your saddle should be positioned so the tibial tuberosity—or the bony bit below the kneecap—is directly above the ball of the foot, which in turn should be above the pedal spindle,” she says.
The patellar tendon is a strong, flat ligament, which originates on the apex of the patella distally and adjoining margins of the patella and the rough depression on its posterior surface; below, it inserts on the tuberosity of the tibia; its superficial fibers are continuous over the front of the patella with those of the tendon of the quadriceps femoris.
It is worse in the morning (after sleeping and not moving). The muscle insertion hurts very focally as it joins into the bone, but there is little to no pain at all with passive motion. Symptoms include multiple points of tenderness at the heel, tibial tuberosity, iliac crest, and other tendon insertion sites.
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 ...
