Where is the tuberosity of the tibia located?
Narrow below the anterio surface of condyle of tibia, where it ends in a large oblong elevation, is the tibial tuberosity, which gives attachment to the ligamentum patellæ; a bursa intervenes between the deep surface of the ligament and the part of the bone immediately above the tuberosity.
Is tibia tuberosity posterolateral or anterolateral?
For the proximal tibia, the tibial tuberosity is anterolateral, the fibular articulation is placed posterolaterally, and the lateral femoral articular surface is smaller, rounder, and set laterally.
What are the signs and symptoms of tibial tuberosity of the knee?
The pain often waxes and wanes for months, increasing with squatting, walking down stairs, or forceful contraction of the quadriceps. The tibial tuberosity is often swollen and tender and may be warm. No effusion is present, and the knee pain is reproducible with resisted extension or passive hyperflexion of the knee.
How does elevation of tibial tuberosity affect patella compressive force?
Anterior elevation of tibial tuberosity increases the efficiency of the quadriceps by increasing the lever arm and at the same time decreasing the PFJRF. According to Maquet, a 2 cm elevation will decrease the patella compressive force by 50%.77,78
What is tibial tuberosity avulsion fracture?
Tibial tuberosity avulsion fractures have been described in rare cases of autograft bone–tendon–bone (BTB) reconstructions.53–55 Tibial tubercle avulsion may occur ipsilaterally with primary ACL reconstruction or in the contralateral leg when using the contralateral patellar tendon autograft in revision cases.
What is the age range for tibial tuberosity?
The lesion usually occurs in boys between the ages of 11 and 15 years and between 8 and 12 years of age. This pattern is directly related to strenuous activity that coincides with the development of the tibial tuberosity (Gholve et al., 2007).
