Outcomes of Patellar Resurfacing in Total Knee Athroplasty

Abstract

he long term results of patients treated with total knee athroplasty (TKA) have revealed that 90% of cases had a 15 year survival rate. However, a considerable proportion of these cases reported poor functional outcomes and persistent anterior knee pain due to patello-femoral joint related problems despite an otherwise well performed knee replacement The role of patellar resurfacing in total knee arthroplasty (TKA) is still debatable. No clear consensus was reported by different studies regarding the mechanical and clinical significance of patellar resurfacing. Many surgeons choose to apply patellar resurfacing on a routine basis, others do not resurface the patella at all, a third group supports resurfacing the patella selectively. Some authors prefer resurfacing argui
