Onlay patellar resurfacing technique

Group Type ACTIVE_COMPARATOR

Total knee with onlay patellar resurfacing technique

Intervention Type PROCEDURE

The patellar resurfacing technique that the patellar implant is embedded on the patellar bone.The patellar implant is placed on top of a flat tibial osteotomy or cut-surfaced bone

Inlay patellar resurfacing technique

Group Type EXPERIMENTAL

Total knee with inlay patellar resurfacing technique

Intervention Type PROCEDURE

The patellar resurfacing technique that the patellar implant is embedded in the patellar bone.The patellar implant is surrounded by a rim of cortical bone and supported by hardened, sclerotic bone
