Isolated unilateral absent patella and contralateral small patella

The "small patella" syndrome.

Twelve closely related members of one family were found to have small or absent patellae. Seven of these patients also had abnormalities of the pelvic girdle and upper femora. There was a resemblance to the nail--patella syndrome in the patellar abnormalities but not in the associated conditions, and it would therefore appear that the syndrome described is a new variety of congenital abnormalit...

Simultaneous, Isolated Traumatic Bilateral Patella Fractures

INTRODUCTION Isolated traumatic fractures of both Patellae, occurring at the same time, in an otherwise healthy person, are very rare. The Patella, as a subcutaneous and a cancellous bone, is vulnerable to injury. However, simultaneous injury to both Patellae without the involvement of any other bony injuries occurs infrequently, and only a few cases have been reported in the literature. CASE...

simultaneous, isolated traumatic bilateral patella fractures

conclusions in simultaneous bilateral patella fractures, good functional outcome can be expected following a stable surgical fixation and a structured rehabilitation regime. however, personality of the fracture determines salvage versus sacrifice of the patella. case presentation we report a rare case of isolated, traumatic bilateral patella fracture with unusual fracture patterns and briefly r...

Bipartite Patella

Osteophytes removal in patella versus lateral facetectomy of the patella in patella-retaining total knee arthroplasty

BACKGROUND In this study, the results of the partial lateral facetectomy of the patella to better patellofemoral motion and congruence are compared with the results of the osteophyte removal of the patella and neurectomy only in total knee arthroplasty (TKA). METHODS Data from 55 patients undergoing TKA with osteophytes removal of the patella and neurectomy only, and those undergoing osteophy...
