Total knee arthroplasty and medial patellofemoral ligament reconstruction for knee osteoarthritis with habitual patellar dislocation: a case report.

ABSTRACT:

Background

Knee osteoarthritis and habitual patellar dislocation are clinically common osteoarticular diseases. However, existing literature lacks reports on their co-occurrence and treatment approaches.

Case presentation

A 78-year-old female developed habitual lateral patellar dislocation of the left knee after an accidental fall over 20 years ago. One year prior, she experienced weight-bearing pain in the left knee. Physical examination, full-length lower limb radiography, and computed tomography confirmed a diagnosis of left knee osteoarthritis with habitual patellar disloca
