Histologic study of periprosthetic osteolytic lesions after AES total ankle replacement. A 22 case series

Severe periprosthetic osteolytic lesions after the Ankle Evolutive System total ankle replacement.

Between 2002 and 2008, 130 consecutive ankles were replaced with an hydroxyapatite (HA) and titanium-HA-coated Ankle Evolutive System total ankle prosthesis. Plain radiographs were analysed by two independent observers. Osteolytic lesions were classified by their size and location, with cavities > 10 mm in diameter considered to be 'marked'. CT scanning was undertaken in all patients with marke...

OPEN PATELLA PERIPROSTHETIC FRACTURE AFTER TOTAL KNEE REPLACEMENT: A CASE REPORT AND REVIEW OF LITERATURES

Arthrodesis after failed total ankle replacement.

We present a series of 16 patients treated between 1993 and 2006 who had a failed total ankle replacement converted to an arthrodesis using bone grafting with internal fixation. We used tricortical autograft from the iliac crest to preserve the height of the ankle, the malleoli and the subtalar joint. A successful arthrodesis was achieved at a mean of three months (1.5 to 4.5) in all patients e...

Predictors of periprosthetic fracture after total knee replacement

BACKGROUND AND PURPOSE Periprosthetic fracture is a devastating complication of total knee replacement (TKR). Most published studies have not comprehensively assessed clinical and demographic predictors. We wanted to determine the incidence and predictors of postoperative periprosthetic fracture after primary and revision TKR. PATIENTS AND METHODS We used prospectively collected data in the M...

Open Periprosthetic Patellar Fracture after Total Knee Replacement

INTRODUCTION Periprosthetic patellar fracture after total knee arthroplasty (TKA) is a rare complication. Their management can be very challenging with unpredictable results. Literature analysis showed few articles about this complication, but no publication has described the management of open patella fracture around total knee arthroplasty. CASE PRESENTATION We report a unique case of an op...
