In Vivo Kinematics for Subjects Implanted With Klassic Total Knee Arthroplasty (TKA)

Completed

Conditions studied: Total Knee Arthroplasty, Osteo Arthritis Knee, Knee Implant, Knee Injuries

In brief

In vivo knee kinematics will be assessed for 20 subjects that have been implanted with a Total Joint Orthopedics Klassic knee system by Dr. Aaron Hofmann of the Hofmann Arthritis Institute's Center for Precision Joint Replacement. This is the location from which all participants will be recruited and where fluoroscopy data collection will occur. Participants will undergo fluoroscopic surveillance of their implanted knee using a C-arm fluoroscopic unit while performing a deep knee bend activity at least six months post-operatively.
