Semitendinosus tenodesis is one of several surgical procedures to improve knee stability.


What is a tenodesis

A tenodesis is a procedure where a tendon is freed from its muscle but remains attached to the bone, and it is then used to help reconstruct an area of instability. This is particularly relevant in children with instabilities where adult reconstruction procedures might damage the growth plate.
