PAPrKA: Physical Activity Patterns after Knee Arthroplasty 

Knee Osteoarthritis (OA) is a degenerative knee joint disease that affects around 250 million people globally. That means one in five people aged over 50 in the UK are affected.  

OA can be treated with an operation called a Knee Arthroplasty, also known as joint replacement. During this operation the damaged knee surfaces are replaced to reduce pain in patients and improve mobility. Before their operation, patients want to know how long their recovery will take and how much mobility they will regain. 

Our study, led by The University of Manchester, will answer those questions. To do this we’ll use the vital data our patients will share with us from their smartphones and wearable fitness devices. 

Project aims 

The Physical Activity Patterns after Knee Arthroplasty (PAPrKA) study is aiming to do three things: 

• To understand physical activity in people with knee osteoarthritis before and after joint replacement. 

• To understand factors that might influence different recovery pathways. 

• To share our findings about how to work successfully with people and access and link their data for research. 

How to take part 

Recruitment for this study will begin in early 2025. More information will follow soon.
