A modified version of Galeazzi’s technique to treat patellar dislocation in adolescent patients has shown good results at mid-term follow-up, according to research published in the Journal of Orthopaedic Science.

In 14 patients treated for patellar dislocation, surgeons used Galeazzi’s semitendinosus tenodesis technique as modified by Baker, with patient results reported as excellent in 62.5% and good in 37.5% of cases, according to the abstract.

A static CT scan showed that all 16 knees in the study had satisfactory congruence; however, a dynamic CT scan showed that, in one group, patellas in 7 knees were not stabilized postoperatively because patients had high patellas. There was no change in results from static and dynamic CT scans in the remaining knees that did not have high patellas.

Researchers included patients measured as Tanner stage ≤3 and were mean 11.6 years old with no less than 2 to 3 episodes of patellar dislocation. Patients were measured preoperatively and for at least 4 years postoperatively.
