Objective To study the curative effectiveness of combination operation in the treatment of congential dislocation of patella. Methods From Jan. 2000 to March 2004, 5 cases of congenital dislocation patella were treated through combination operation and these cases were reviewed. There were 2 cases of mono-knee dislocation and 3 cases of bi-knee dislocation. The combined operations included lateral retinacular releas, medial retinacular tightening of the knee, vastus medialis transfer to patella, medial and distal transfer of the half patellar tendon, medial transfer of the tibia tubercle. They were followed up on average for 4 months to 4 years. Results All patients had the stable knee joint and a full range of motion, and motor functions were obviously improved after operation. The re-dislocation and restriction of the knee joint motion were not found. Conclusion The combined operation for the congenital dislocation of the patella in children can obtain satisfactory curative effectiveness.
