The outcome of three methods of patellar resurfacing in total knee arthroplasty (original) (raw)

1995, International Orthopaedics

Two hundred and three patients with 219 Miller GaIante type I knee arthroplasties have been reviewed in a multicentre study at an average of 3.5 years after operation. Three groups are compared: 83 patients were treated with a full polyethylene patellar component; 68 with a metal backed component, and 68 with patellar debridement without resurfacing. We found no differences between the 3 groups in relation to pain, range of movement, stability, flexion or extension deficit, extension lag, alignment, walking distance, ability to climb stairs or the use of walking aids. There was also no difference in the incidence of patellofemoral complications. The number of revision operations was the same in patellar-resulfaced and non-resurfaced knees. Lateral release was accompanied by more complications in every subgroup. R6sum6. Dans un travail multicentrique nous avons dtudid 219 arthroplasties de Miller Galante type 1 chez 203 patients avec un suivi postopdratoire de 3.5 ansen moyenne (de 2 gt 6). On a compard trois modes de traitement: 83 fois un implant rotulien en polydthylbne, 68 fois une plaque mdtallique post~rieure, les 68 autres malades furent trait& par ddbridement simple sans rev&ement artificiel de la surface articulaire., On n 'a trouvd aucune diffdrence entre les trois groupes quant gt la douleur, la mobil#d, la stabilitd, le ddficit de flexion ou d'extension, l'impossibilitd
