title: Medium-term results of patellofemoral joint arthroplasty.
abstract: The results of a multi-surgeon, multi-implant series of patellofemoral joint arthroplasties performed over a ten year period are presented. All patellofemoral joint arthroplasties performed from 1997 to 2006 were retrospectively reviewed using case notes, radiographs and clinic appointments until their latest follow-up period. One hundred and one arthroplasties in 91 patients were followed up for an average period of 48 months (range 6-96 months). The average age was 57 years with female patients thrice as common as male patients. There were 5 (5%) complications with 1 deep infection and 4 stiff knees. Thirty five subsequent procedures were performed in 28 patients including arthroscopic debridement in 18, arthroscopic lateral retinacular release in 8, tibial tuberosity transfer in 3, manipulation for stiffness in 2, and revision to total knee arthroplasty in 4 patients (3 for progression of tibiofemoral osteoarthritis and 1 for infection). The necessity of further surgeries in one third of the study group suggests that close follow-up of these patients is needed to address any concerns that can be easily resolved.
