Fabella Fractures after Total Knee Arthroplasty with Correction of Valgus Malalignment

Fabella Fractures after Total Knee Arthroplasty with Correction of Valgus Malalignment

The incidence of fabella fractures is considered to be extremely low. This report presents two patients with femorotibial osteoarthritis and considerable preoperative valgus malalignment, who developed a fracture of the fabella (as demonstrated by radiography) after total knee arthroplasty with intraoperative correction of the valgus malalignment. Special attention should be paid to the fabella...

Patellar 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, ...

Moderate varus/valgus malalignment after total knee arthroplasty has little effect on knee function or muscle strength.

BACKGROUND AND PURPOSE Postoperative muscle strength and component alignment are important factors affecting functional results after total knee arthroplasty (TKA). We are not aware of any studies that have investigated the relationship between them. We therefore investigated whether coronal malalignment of the mechanical axis and/or of individual implant components would affect knee muscle str...
