THE FPV PATELLO-FEMORAL JOINT REPLACEMENT: MID-TERM RESULTS FROM AN INDEPENDENT DISTRICT GENERAL HOSPITAL
2018
The Femoro Patella Vialli (FPV) is indicated for isolated patello-femoral joint replacement (PFJR). It is now the second most commonly used PFJR in the UK, however there are limited studies evaluating its outcome. Key differences include a larger component sulcus angle of 140 degrees which more closely mimics the normal knee.Between 2006 and 2012, we performed 53 consecutive FPV patellofemoral arthroplasties in 41 patients with isolated patellofemoral joint osteoarthritis. Mean age was 62.2years (39–86) and mean follow-up was 3.5 years. Mean Oxford Knee scores improved from 19.7 to 37.7 at latest follow-up. Ninety four percent of patients were happy or very happy with their knees. Progression of tibiofemoral osteoarthritis was seen 12% of knees. 2 knees required revision to TKR at 7 months post-operatively, which we attribute to poor patient selection. There were no cases of maltracking patella or patella dislocations at final follow-up, which we attribute to the larger sulcus angle. There were no cases o...
