Patellar instability after total knee arthroplasty.
Twenty-five knees with symptomatic lateral patellar instability after total knee arthroplasty (TKA) were treated by operative realignment. Causes of instability include errors in surgical technique, quadriceps imbalance, and trauma. Fourteen knees had proximal realignment, nine had combined proximal and distal realignment, and two had component revision. At an average follow-up period of 50 mon...
متن کاملAcute Patellar Tendon Rupture after Total Knee Arthroplasty Revision
Patellar tendon rupture is a catastrophic complication following total knee arthroplasty (TKA). Though revision TKA has been suspected of being a predisposing factor for the occurrence of patellar tendon rupture, there are few reports on patellar tendon rupture after revision TKA. Here, we present a case of acute patellar tendon rupture that occurred after TKA revision. In the patient, the pate...
متن کاملPatellar meniscus in total knee arthroplasty.
Twenty-four clinically successful, autopsy retrieved porous-coated anatomic total knee arthroplasty (TKA) specimens were evaluated to determine the structure and function of the patellar meniscus. Mean implant duration was 76 months (range: 11-135 months). Histological examination showed the patellar meniscus to be composed of dense fibrous tissue with scattered regions of chronic granulomatous...
متن کاملPatellar malalignment treatment in total knee arthroplasty.
The patella, with or without resurfacing, plays a fundamental role in the success of a total knee arthroplasty (TKA). Patellofemoral joint complications are due to problems related to the patient, to the surgical technique, or to the design of the components. Patellar tracking is influenced by several factors: a severe preoperative valgus, the presence of pre-existing patellofemoral dysplasia, ...
متن کاملPatellar Dislocation after Total Knee Arthroplasty for Neglected Chronic Post-traumatic Patellar Dislocation: A Case Report
Introduction Chronic post-traumatic dislocation of the patella is rare and results in persistent dislocation throughout the arc of motion of the knee. Whereas newborns with trochlear dysplasia may exhibit congenital patellar dislocation, typical delayed presentation in adults is often due to trauma and can progress to painful motion and secondary osteoarthritis. Although rare, recurrent disloca...
