He reported that quadriceps contracture patients may present in a variety of ways. Physical examination did not reveal general joint laxity or malalignment of the lower extremity. The passive lateral patellar tilt test was negative since the soft tissue attachment to the lateral border of the patella was diffusely stiff and tight.

Hbitual Bone Joint Surg. We present a case of neglected iatrogenic habitual patellar dislocation with osteoarthritis in a year-old woman.

They found that vastus medialis was so deficient that muscle advancement was not possible.


He recommended cautious physical examination regarding patella tracking since radiological examinations, including skyline view do not always show the pathophysiology of patellar instability.

It was not seen in cases with history of trauma. Criteria which allowed him to return to work were no pain, stability of the patella, no swelling, and full range of motion. An MRI or ultrasound might fislocation shown features of the MPFL and the attachment of the vastus medialis internus on the patella, but these results were not available for the preoperative work-up.

The postoperative course was simple with no complications.
