Patellar Fractures in Adults
J. Stuart Melvin, MD and Samir Mehta, MD J Am Acad Orthop Surg 2011 19 Patellar fracture is a common injury caused by excessive tension through the extensor mechanism or a direct blow. The intact patella increases the leverage and efficiency of the extensor mechanism and articulates with the femoral trochlea. Patellar fractures can lead […]
The Use of Highly Cross-linked Polyethylene in Total Knee Arthroplasty
J Am Acad Orthop Surg, Vol 19, No 3, March 2011 Paul F. Lachiewicz, MD and Mark R. Geyer, MD Polyethylene wear, with resultant particle-induced osteolysis, is a cause of late failure of total knee arthroplasty. The causes of both wear and osteolysis are multifactorial; still, improvements in the polyethylene liner have been investigated. Available […]
The Role of Trochlear Dysplasia in Patellofemoral Instability
NULL Matthew Bollier, MD and John P. Fulkerson, MD J Am Acad Orthop Surg, Vol 19, No 1, January 2011, Trochlear dysplasia is characterized by abnormal trochlear morphology and a shallow groove.
