What is lateralization of tibial tuberosity?

Lateralization of the Tibial Tubercle. Alters downward force vector on patella during flexion to a more lateral vector, predisposing to maltracking/dislocation.

How is a tibial tuberosity fracture treated?

The goal of treatment for fractures of the tibial tubercle is to restore the extensor mechanism and the joint surface, when disrupted. Closed treatment generally entails closed reduction and immobilization in a long leg or cylinder cast for approximately 4 weeks or until evidence of union is apparent on radiographs.

What is a tibial tubercle osteotomy?

Tibial Tubercle Osteotomy (TTO) is a surgical procedure to improve alignment of the patella. This is performed by changing the insertion point of the patellar tendon on the tibia (tibial tubercle).

What is mild lateralization of the patella?

This is called patellar lateralization (outward drifting of the kneecap) or patellar subluxation. The drifting out oft he slide bearing leads to an increased contact pressure of the kneecap onto the slide bearing, which can damage the joint cartilage and eventually leads to an arthrosis.

How common is Trochlear dysplasia?

The patellofemoral joint presents a complex biomechanical interaction involving soft tissues and bony structures to maintain joint stability. The most relevant factor is trochlear dysplasia which is present in 85% of patients. Femoral trochleoplasty is a surgical procedure to recreate the trochlear groove.

Is the tibial tuberosity a bone?

The tuberosity of the tibia or tibial tuberosity or tibial tubercle is an elevation on the proximal, anterior aspect of the tibia, just below where the anterior surfaces of the lateral and medial tibial condyles end….
