One or both knees may be affected and flares may recur. Episodes of pain typically last a few weeks to months.
Some studies correlate avulsion of the tibial tuberosity with associated injuries of the knee 6 1012 as meniscal tears collateral ligaments ruptures capsule avulsion and intra articular fractures but we also could not find any on the clinical examination.
Tibial tuberosity injury. Tibial tuberosity avulsion fractures are uncommon pediatrie injuries. They comprise approximately 1 of all physeal fractures and approximately 3 of all proximal tibial injuries4 most fractures. Osgoodschlatter disease osd is inflammation of the patellar ligament at the tibial tuberosity apophysitis.
Tibial tuberosity fractures are rare injuries with a reported incidence of 04 to 27. Tibial tubercle fractures are a common fracture that occurs in adolescent boys near the end of skeletal growth during athletic activity. These injuries usually occur in adolescent aged males participating in sports particularly basketball.
Definition of tibial tuberosity in the medical dictionary by the free dictionary. These injuries usually occur in the early postoperative period and have been. It is characterized by a painful bump just below the knee that is worse with activity and better with rest.
In contrast to the proximal tibial epiphysis which develops in compression the tibial tuberosity is an apophysis and develops in traction. The tibial tuberosity develops from a secondary ossification center in the proximal aspect of the tibia. Epidemiology these fractures have an incidence 04 to 27 and males are affected more so than females.
Treatment is closed reduction and casting or surgical fixation depending on the degree of displacement. Tibial tuberosity avulsion fractures are uncommon. Explosive quadriceps contraction against a fixed foot or rapid eccentric knee flexion are biomechanics typifying jumping activities which predispose a vulnerable tibial apophysis to avulsion injuries.
5355 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. Tibial tuberosity avulsion fractures have been described in rare cases of autograft bonetendonbone btb reconstructions. The typical patient is an adolescent male approaching skeletal maturity with well deve.
