摘要

AIM:To determine outcomes using the Femoro-Patella Vialla(FPV)arthroplasty and if there is an ideal patient for this implant.METHODS:A total of 41 FPV patellofemoral joint replacements were performed in 31 patients(22 females,9 males,mean age 65 years).Mean followup was 3.2 years(minimum 2 years).Radiographs were reviewed preoperatively and postoperatively.We assessed whether gender,age,previous surgery,patella atla or trochlear dysplasia influenced patient satisfaction or patient functional outcome.RESULTS:The median Oxford Knee Score was 40 and the median Melbourne Patellofemoral Score was 21 postoperatively.Seventy-six percent of patients were satisfied,10%unsure and 14%dissatisfied postoperatively.There was no radiological progression of tibiofemoral joint arthritis,using the Ahlback grading,in any patient.One patient,who was diagnosed with rheumatoid arthritis postoperatively,underwent revision to total knee replacement.There were no intraoperative lateral releases and no implant failures.Gender,age,the presence of trochlear dysplasia,patella alta or bilateral surgery did not influence patient outcome.Previous surgery did not correlate with outcome.CONCLUSION:In contrast to the current literature,the FPV shows promising early results.However,we cannot identify a subgroup of patients with superior outcomes.
