Brief Summary: Patients who have had a total ankle joint replacement surgery typically have limited movement in their ankles possibly due to the fact that commonly used ankle joint prosthetic devices only allow limited axes of motion

This study will evaluate the ability of a Scandinavian Total Ankle Replacement STAR mobile-bearing prosthesis and INBONE 2 fixed-bearing prosthesis to restore triplanar motion in the tibiotalar ankle joint following a surgical arthroplasty total joint replacement procedure

3D X-ray video motion analysis will be utilized to quantify range of motion measurements in two groups of ankle prosthesis users and a group of matched control participants
Detailed Description: 15 study participants will include those using a Stryker STAR prosthesis and a Wright Medical INBONE 2 prosthesis and a group of matched control subjects

CT scans of lower limb anatomy ankle-foot complex will be obtained for all subjects to be converted into 3D bone surface models for use in the joint motion tracking software

Each participant will participate in one day of data collection with an X-Ray Motion Analysis XMA system High-speed biplanar XMA system will capture video images of the skeletal motions within the foot-ankle complex during normal movement Subjects will walk and perform controlled movements in the capture volume within the XMA system

Following data collection the 3D bone surface models will be mapped to the sagittal side view coronal front view and axial top view plane skeletal motions demonstrated in the collected x-ray videos Motion tracking data will then be used to accurately animate the 3D bone models to demonstrate the active range of ankle-foot joint motions during voluntary movement and gait

Resulting range of motion measurements in dorsiflexionplantarflexion internalexternal rotation and inversioneversion will be used to determine the extent to which normal motion in the ankle-foot complex has been restored in ankle prosthesis users
