Abstract
Medial patellofemaral ligament (MPFL) reconstruction is the popular procedure for patellar dislocation, but the plication procedure of the MPFL is not so popular. We reported two cases of plication of the MPFL, one following patellar fracture-dislocation and one following patellar dislocation. The first case was a 28-year-old man who suffered a left patellar fracture-dislocation. The patient underwent plication procedure of the MPFL and primary fixation of an osteochondral fracture three days after injury. Eight months after surgery, no discomforting symptoms were diagnosed. Radiography revealed good bony union and satisfying congruity of the patello-femoral joint. The second case was a 14-year-old girl who suffered a right patellar dislocation. The patient underwent the plication procedure of the MPFL and the Elmslie-Trillat surgery six months after injury. Six months after surgery, slight thigh muscle atrophy was diagnosed but the patient did not complain of any discomfort. Radiography revealed satisfying congruity of the patellofemoral joint and the MPFL was clearly observed by magnetic resonance imaging (MRI). The results of the plication procedure of the MPFL for both cases were satisfying at the last follow-up examination.
