Abstract:
We present a case of bilateral patellar component dissociation 6 years after bilateral total knee arthroplasty. The patient had undergone arthroscopic lateral releases bilaterally for patellar maltracking. After repetitive trauma, the patient experienced patellar component dissociation, which was treated arthroscopically by removing the patellar components and leaving the patellae unresurfaced. The patient's symptoms improved substantially. Our case highlights certain features of the etiology as well as the management of patellar component dissociation in the total knee arthroplasty, showing the important role of arthroscopy.
