INTERPRETATION There was a clinical ly relevant association between early migration of TKPs and late revision for loosening .
PURPOSE We performed two parallel systematic review s and meta-analyses to determine the association between early migration of tibial components and late aseptic revision .
Resurfacing versus not resurfacing the patella in total knee arthroplasty: 8- to 10-year results.
Patellar resurfacing in total knee arthroplasty is a topic debated in the literature . Concerns include fracture , dislocation , loosening , and extensor mechanism injury . Residual anterior knee pain has been reported when the patella is not resurfaced . One hundred patients with osteoarthritic knees were prospect ively r and omized to either have their patella resurfaced or left not resurfaced . All patients were treated with a single prosthesis that featured an anatomically design ed patellofemoral articulation ( Anatomic Medullary Knee , DePuy , Warsaw , IN ) Two patients in the unresurfaced group and one in the resurfaced group required repeat surgery for patellofemoral complications . At 8- to 10-year follow-up evaluations , Knee Society Clinical Ratings scores were not different between the 2 groups . Rates of anterior knee pain with walking and stair climbing were significantly less in the resurfaced group . Eighty percent of patients with a resurfaced patella were extremely satisfied with their total knee arthroplasty versus 48 % without patellar resurfacing . When satisfied and extremely satisfied patients were grouped together , there was no difference between the 2 groups
