PAPrKA: Physical Activity Patterns after Knee Arthroplasty\u00a0<\/h1>\n

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.\u00a0\u00a0<\/p>\n

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.\u00a0<\/p>\n

The PAPrKA study linked fitness data gathered from participants’ smartphones and wearable fitness devices with existing health records. Recruitment has now ended and the analysis has begun.<\/p>\n

Interview – Matt Barker’s experience<\/strong><\/p>\n

Matt Barker, a former Iron Man Triathlete underwent a knee replacement surgery in November 2022. Having heard about our study, he discussed his experiences and the impact on his daily movement following surgery in the article<\/a> released by the University and in the full\u00a0Q&A interview below:<\/p>\n

  1. When did you have a knee replacement?<\/strong><\/li>\n<\/ol>\n

    November 2022 \u2013 this was a partial knee replacement and followed a microfracture procedure on the same knee 5 years previously<\/p>\n

      \n
    1. Can you describe what daily life was like for you prior to the surgery?<\/strong><\/li>\n<\/ol>\n

      It was becoming increasingly difficult. Standing was painful. I was unable to move anywhere quickly and had to give up most of my active lifestyle (certainly no running, and country walks became more and more limited). My job as a teacher required me to be on my feet for most of the day \u2013 teaching, moving around school, daily duties and so on \u2013 and each day my knee would become progressively more swollen and painful throughout the day. Walking downstairs and down any kind of slope was especially difficult. Colleagues would worry about me and ask if I was alright; this was especially difficult as I still mentally saw myself as a fit and active person, but the daily reality was that I was becoming more and more restricted.<\/p>\n

        \n
      1. What made you decide to have surgery?<\/strong><\/li>\n<\/ol>\n

        It was a combination of factors:<\/p>\n
