Secondary habitual patellar dislocation

Keywords

This case illustrates a 27-year-old women who underwent thirteen years ago a realignment surgery for recurrent patellar dislocation in her left knee. She continued to have dislocations episodes which became habitual in the last year with more than 30º flexion.

The preoperative radiological assessment showed a shallow trochlear groove and a lateralized tibia tuberosity with pathological TA-TGT values.

Intraoperatively the patella had lost its normal facet anatomy with 3-4 cartilage degenerative changes, and the trochlea was also completely flattened with 2-3 degenerative changes.

A tibial tubercle medialization of 10 mm with a mild Fulkersson effect (5º lateral osteotomy inclination), a vastus medialis advancement and a lateral release as far as the vastus lateralis obliquus was performed.

After a 9 month rehabilitation program based on early ROM exercises and isokinetic strengthening the patient has regained full flexion, with no dislocation/apprehension events, no pain and has started to practice again highly demanding sport.

    Interesante caso en que demuestra la eficacia de la reparación de la anatomía alterada para recuperar buena función del aparato extensor.  Un pregunta ¿No se realizó ningún gesto quir´rugico en la zona lesionada del cartílago rotuliano?
