For what problems is distal realignment indicated?
Distal realignment may be performed for recurrent patellar instability, such as recurrent subluxation or dislocation.
"....distomedial...tibial tubercle transfer....led to clinically relevant functional improvement and pain reduction in patients with patellar maltracking and patella alta without instability...."
"....regardless of the type of medialization procedure employed, over- and undercorrection must be avoided...."
"....However, the....[removal of hardware]....rate was high (72%)"
What are the various distal realignment procedures?
The various procedures have evolved over the years and include -
Relevance of the TT-TG distance
To assess how far the tibial tubercle and the trochlear groove are out of alignment, the surgeon will use scan pictures to calculate the TT-TG distance, and use this as a guide for correction.
