The Association of Gait Kinematics, Instability and Patient Reported Outcomes in Patients With Total Knee Replacement

Summary

It is unclear why 20% of patients with total knee replacements (TKR) are dissatisfied. Few studies have specifically assessed the way people walk ('gait') with an 'unhappy' or unstable knee or following re-do ('revision') TKR surgery.

The investigators conjecture that people having re-do TKR surgery because their knee is unstable will have altered walking patterns (for example, less bending of the knee) before and after surgery, and that these changes are related to how satisfied the patient is with their knee. The investigators will also examine whether there are differences in the way people walk with an unstable knee replacement or with a stable knee replacement, in comparison to people who do not have a knee replacement.

This exploratory project will use 3D infrared cameras to analyse differences in walking patterns and whether there is associated change in patient satisfaction. If an association exists, the data from this study may help to develop alternative measures of outcomes, in order to guide treatment decisions.

Conditions

  • Arthroplasty, Replacement, Knee

Interventions

PROCEDURE

Revision TKR surgery

This study will follow the cohort of patients who have an unstable primary TKR with which they are dissatisfied. They will be assessed before and after their revision TKR surgery.

OTHER

No intervention.

This study will also make a case-control comparison between patients with a stable primary TKR and an unstable primary TKR.
