Movement Dynamics of Knee Osteoarthritis and Total Knee Replacement (MDOA&TKR)

February 19, 2025 updated by: Josie Morris, University of Portsmouth

Quantifying the Movement Dynamics of Adults Living with Total Knee Arthroplasty and Knee Osteoarthritis

This research aims to explore differences in walking and functional movement mechanics, exercise response, and physical activity between people with osteoarthritis (OA), those who have undergone total joint replacement, and healthy individuals.

Detailed Description

People living with OA tend to be less physically active than those without the disease, which is often due to pain, stiffness and joint instability. This reduction in physical activity can lead to additional health problems down the line. When the disease becomes severe, joint replacement surgeries are sometimes performed to relieve pain and improve individuals' quality of life. However, despite reducing pain, there is little evidence to show that joint replacement surgeries encourage individuals to return to healthy physical activity levels.

Reasons for the lack of change may include a failure to address unhealthy walking and movement patterns which could still be causing pain and instability and reduced physical fitness levels.

By investigating these reasons, we hope that findings from this study will help to inform future interventions that improve clinical outcomes and quality of life for individuals with OA and post-joint replacement.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Peak knee adduction moment
Time Frame: From the start of a biomechanical movement testing visit to the end (approximately 2 hours)
The external knee adduction moment (KAM), which reflects medial-to-lateral knee joint load distribution during gait, has become an OA treatment target. The peak KAM is a strong predictor of presence, severity, and the rate of progression of knee OA.
From the start of a biomechanical movement testing visit to the end (approximately 2 hours)
