Patella morphological alteration after patella instability in growing rabbits

Patella morphological alteration after patella instability in growing rabbits

BACKGROUND The shape of the patella has been considered to be a predisposing factor resulting in patellar instability, but the effects of abnormal patella position during its development are unclear. The present study evaluated patellar morphological changes after patella instability and evaluated the influence of patellar instability on the patella shape. METHODS Twenty rabbits that were 2 m...

Patella instability in children and adolescents

Patellar instabilities are the most common knee pathologies during growth. Congenital dislocations are rare. Extensive, early soft tissue releases relocate the extensor mechanism and may enable normal development of the femoro-patellar anatomy.Conservative management is the preferred strategy after a 'first-time' traumatic dislocation. In cases with concomitant anatomical predisposing factors s...

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...
