Arthrosurface Launches Patellofemoral WaveKahuna Arthroplasty Implant

Share:

Arthrosurface introduced its next-generation Patellofemoral (PF) WaveKahuna™ arthroplasty system.

PF WaveKahuna is designed to restore the articular surface geometry of the patella and femoral trochlear groove, while maintaining patients' native joint anatomy. The hybrid inlay/onlay design incorporates a distal femoral trochlear groove implant that mates to a taper post via morse taper interlock. It is a larger than the original Arthrosurface PF Wave™, and combines both dome and anatomical patella components.

The implant is designed for cemented arthroplasty in patients with osteoarthritis of the distal patellofemoral joint, those with a history of patellar dislocation or patellar fracture and those with failed previous surgery where pain, deformity or dysfunction persist.
