Summary
Brief summary
The purpose of the current investigation is to assess the safety and efficacy of a new hinged revision knee device. This device is designed to provide efficient, reproducible reconstructions with optimal limb and implant alignment, durable implant fixation, and functional outcomes that increasingly approach those of primary Total Knee Arthroplasty (TKA).
