Highlights
Acute patellar dislocation is primarily an injury of active young patients of both sexes, with a higher recurrence rate in female patients[1])
According to Amis et al.4), a rupture of this structure always occurs in lateral patellar dislocation because the medial patellofemoral ligament (MPFL) can undergo a maximum elongation of 20%–30%; this is far less than the patellar width, which often exceeds 40 mm4)
The MPFL is often damaged during patellar subluxation or dislocation, and over the last decade, several authors have recommended repair or reconstruction of the MPFL to reduce the high incidence of recurrent dislocation, and many different MPFL surgical reconstruction or repair techniques have been described in the literatures5)
Summary
Acute patellar dislocation is primarily an injury of active young patients of both sexes, with a higher recurrence rate in female patients[1]). The medial patellofemoral ligament (MPFL) deficiency was reported to be 50% to 96% in those who had experienced traumatic patellar dislocation during open surgical exploration[3]). Lee et al.10) reported on MPFL anatomical measurements in Koreans: the width at the patellar attachment was 14.2 mm (range, 10 to 15 mm), the width at the femoral insertion was 11.5 mm (range, 10 to 12.3 mm), the average length of the upper border was 53.2 mm (range, 47.7 to 59.3 mm) and that at the lower border was 55.4 mm (range, 51.0 to 59.7 mm), and the thickness was 1.7 mm (range, 1.1 to 3.0 mm) on the patellar side and 1.1 mm (range, 0.6 to 1.6 mm) on the femoral side. The femoral attachment has been spread by decussating fibers that are attached to both the adductor tubercle and to the superficial fibers of the medial collateral ligament with more direct attachment to the epicondyle[11])
