- During total knee arthroplasty (TKA), whether or not one should routinely resurface the patella is controversial.
- Leaving an unresurfaced patella following index TKA may lead to anterior knee pain (AKP), patellofemoral crepitus, and future secondary resurfacing operations.
- However, routinely resurfacing the patella (PR) may lead to patellar fracture, aseptic loosening, patellar instability, avascular necrosis, and patellar clunk.
- The purpose of the present study is to utilize the existing level one evidence to assess the cost-utility of routine patella resurfacing during primary TKA.
- Hypothesis: Selective resurfacing of the patella is more cost effective than routine patellar resurfacing during primary TKA.
