Summary

A patient with Rubinstein Taybi Syndrome experienced spontaneous patella dislocation and reduction. Early surgical intervention for patellar instability is recommended in RTS patients despite developmental delays.

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...

Background:

Rubinstein Taybi Syndrome (RTS) is a rare genetic disorder characterized by intellectual disability, distinctive facial features, and broad thumbs/toes.
Patellar instability is a known orthopedic complication in some genetic syndromes, but specific patterns in RTS are not well-documented.

Observation:

A case of Rubinstein Taybi Syndrome presented with recurrent, spontaneous patella dislocation and reduction.
Clinical assessment revealed significant ligamentous laxity and a reducible patella, indicating inherent joint instability.

Findings:

The patient underwent successful open reduction and stabilization of the patella, utilizing a semitendinosus tenodesis procedure.
This surgical approach addressed the patellar instability in the context of RTS.

Implications:

The findings suggest that orthopedic interventions for patellar instability should not be delayed in children with RTS, even with associated motor and psychomotor delays.
This case highlights an unusual presentation of patellar dislocation in RTS, emphasizing the need for tailored orthopedic management in this population.
