Objective: To evaluate the clinical and
functional results of two surgical treatments of patellar dislocation in
children. Material and Methods: A prospective study was undertaken from January
1995 to December 2009. Pre-postoperatively, the clinical and roentgenographic
examinations were performed. Patellar dislocation was classified according to
Bensahel’s criteria. There were two surgical techniques performed: 1) the iliotibial
tract passing through patella (ITT), and 2) transferring
vastus medialis oblique muscle to superior border patella (VMO). Lateral
retinacula were released to restore the tension of the medial retinacula and quadricepsplasty
was used in all patients. The results of the operations were classified according
to Kujala’s functional knee-scor- ing systems. Results: 128 patients (132
knees) were operated. There were 20 males and 108 females. 94 knees (71.2%)
were Type 1, and 38 knees (28.8%) were Type 2. The ITT was in 74 patients (76
knees), and VM was in 54 patients (56 knees). Clinical signs, imaging finding
before and after the operation and operative results of these patients were
operated with ITT and VM with no
significant difference (p > 0.05).
Overall, we attained excellent results in 95 knees (72.0%), good results in 30
knees (22.7%), and fair results in 7 knees (5.3%). There have been no poor
results or recurrences so far. Conclusion: These techniques are simple, safe
and effective in skeletally immature children. Long-term follow-up of these patients
was operated ITT and these patients which were operated VMO were not different, but time for
operation was: ITT: 65 minutes, and VMO: 55 minutes.
