Patella

Dysplasia of the femoral trochlea is complex and variable. Why it occurs is poorly understood. Some believe that trochlea dysplasia is genetically determined and some believe that it is a result of aberrant forces through the joint (form follows function) during growth. Recent evidence suggests that aberrant forces lead to dysplasia.

According to recently published results, medial open-wedge high tibial osteotomy adversely affected the patellofemoral joint.

A 36-year-old man was referred for the management of ongoing posterior right knee pain and discomfort following a complicated surgical history for his knee. He sustained a partial tear of his right quadriceps tendon in 2003 and underwent surgical repair. In 2004, he sustained a complete retear of the same quadriceps tendon and underwent revision surgery. In 2017, he sustained another knee injury at which time he underwent arthroscopic partial medial and lateral meniscectomy.
