Background: Patellar crepitus after total knee arthroplasty (TKA) is not uncommon. The choice between patellarresurfacing or retention in TKA has remained controversial. Therefore, this randomized controlled trial aimed to evaluatethe impact of patellar resurfacing on the incidence of patellar crepitus. In addition, we compared the clinical outcomesand satisfaction between the...

Background: There is no difference in the functional outcomes 6 months after total knee arthroplasty (TKA) for kneeosteoarthritis between patellar resurfacing and non-resurfacing. Thus, we have performed this study to compare theshort-term clinical outcomes of TKA performed with and without the patella resurfacing.Methods: A total of 50 patients with osteoarthritis of the knee (OAK) were random...

Background and purpose - Knee pain after total knee arthroplasty (TKA) is not uncommon. Patellar retention in TKA is one cause of postoperative knee pain, and may lead to secondary addition of a patellar component. Patellar resurfacing in TKA is controversial. Its use ranges from 2% to 90% worldwide. In this randomized study, we compared the outcome after patellar resurfacing and after no resur...

Among patients that underwent total knee arthroplasty from June, 1990 to January, 1999, 61 cases (44 patients) that could be followed for more than 10 years were included in this study. The patients were divided into a patellar retention group and a patellar resurfacing group, and were compared with regard to their clinical and radiological outcomes. In patients undergoing primary TKA, a select...

Background: Patellar resurfacing after routine arthroplasty remains controversial. Few studies have specifically examined the effect of patellar resurfacing on outcomes after resection of the distal part of the femur and reconstruction with a megaprosthesis. Our objective was to compare the outcomes of megaprosthesis reconstructions of the distal part of the femur with and without patellar resu...

350 knees were evaluated in a prospective, randomized, double-blinded study of selective patellar resurfacing in primary total knee arthroplasty. Knees with exposed bone on the patellar articular surface were excluded. 327 knees were evaluated at a mean follow-up of 7.8years. 114 knees followed for greater than 10 years were analyzed separately. Satisfaction was higher in patients with a resurf...

Total knee arthroplasty (TKA) is a well-established procedure, and has proven to be durable and effective for the treatment of advanced arthritis of the knee joint. Early TKAs did not include patellar replacement and anterior knee pain was reported after the procedure had been carried out. The incorporation of patellar resurfacing during TKA reduces anterior knee pain, although new complication...

Tel: +90 312 202 55 28 Fax: +90 312 212 90 08 e-mail: [email protected] We avoid routine patellar resurfacing during knee replacement because of the risk of major complications that include patellar fracture, avascular necrosis, patellar tendon injury and...

BACKGROUND Changing the kinematic behaviour of patellar movement could be one of the reasons for anterior knee pain after implantation of a total knee arthroplasty (TKA). The aim of the current study was to measure the potential influence on patellar kinematics of patellar resurfacing during TKA. METHODS Patellar movement before and after TKA with and without patellar resurfacing was measured...
