The MAKO Surgical Corp. Patellofemoral Knee Implant System II is intended to be used in cemented patello-femoral arthroplasty in patients with degenerative arthritis in the distal femur and patella, patients with a history of patellar dislocation or patella fracture, or patients with failed previous surgery (arthroscopy, tibial tubercle elevation, lateral release) where pain, deformity or dysfunction persists. These components are single use only and are intended for implantation with bone cement.

This device consists of a CoCrMo patellofemoral component and an ultra-high molecular weight polyethylene patella components are intended for cemented, one-time use only. The anterior surface of the patellofemoral component is polished and features a trochlear groove. The posterior surface of the patellofemoral and patella component employ features such as cement pockets and pegs for enhanced stability of the prosthesis when cemented onto the femur and patella, respectively.
