NCT01705366

Brief Summary

The objective of this study is to document the demographic and clinical characteristics and the long-term clinical outcomes of patients who require a robot assisted knee arthroplasty. The hypothesis is that MAKO® robot assisted surgery replacing one or two compartments of the knee joint has 10 year implant survival and clinical outcomes that are equivalent to other knee replacement systems.

Study Arms (1)

Knee Arthroplasty

Patients undergoing total knee arthroplasty. This may be Non-MAKO® Robot Assisted Total Knee Arthroplasty or MAKO® Robot Assisted Medial Knee Arthroplasty or MAKO® Robot Assisted Medial and PF Knee Arthroplasty The Non-MAKO® Robot Assisted Total Knee Arthroplasty uses the Depuy Knee Replacement System or the Stryker® Knee Replacement System. The MAKO® Robot Assisted Arthroplasty uses the RESTORIS Multicompartmental Knee System .

Procedure: Non-MAKO® Robot Assisted Total Knee ArthroplastyProcedure: MAKO® Robot Assisted Medial Knee ArthroplastyProcedure: MAKO® Robot Assisted Medial and PF Knee ArthroplastyDevice: RESTORIS Multicompartmental Knee SystemDevice: Depuy Knee Replacement SystemDevice: Stryker® Knee Replacement System

Interventions

Patients undergoing a non-MAKO® robot assisted surgery to replace one or more compartments of the knee.

Also known as: TKA, Total Knee Replacement, Revision Knee Arthroplasty
Knee Arthroplasty

Patients undergoing a MAKO® robot assisted surgery to replace the medial compartment of the knee.

Also known as: Unicompartmental Knee Arthroplasty (UKA)
Knee Arthroplasty

Patients undergoing a MAKO® robot assisted surgery to replace the medial and patellofemoral (PF) compartments of the knee

Also known as: Bi-compartmental Knee Arthroplasty
Knee Arthroplasty

The RESTORIS Multicompartmental Knee (MCK) System components are intended for single or multicompartmental knee replacement used in conjunction with the MAKO® Robotic Arm Interactive Orthopedic System (RIO®). The components can be used for medial compartment, lateral compartment, patellofemoral compartment, or bicompartmental (medial and patellofemoral compartments) knee replacement. The device is intended to be used with bone cement.

Also known as: RESTORIS® MCK MultiCompartmental Knee System, FDA 501K number K090763
Knee Arthroplasty

The Depuy Knee Replacement System components are intended for use in total knee replacement. These components are intended for implantation with bone cement.

Knee Arthroplasty

The Stryker® Knee Replacement System components are intended for use in total knee replacement. These components are intended for implantation with bone cement.
