Abstract
Individuals who have undergone knee arthroplasty may still want to run, but no study has reported a progression to guide patients and clinicians. The objective of this case report is to document the process of returning to running after total knee arthroplasty with a 1-year follow-up. The client was a 55-year-old woman, former triathlete, who underwent unilateral knee arthroplasty 1 year prior to consultation. She alternated slow running with walking and increased based on symptoms. She also performed a lower limb exercise programme. The client was a low-impact forefoot striker, ran with a high step rate and wore minimalist shoes. During the 1-year follow-up, she reported no knee pain but experienced minor episodes of calf strains. Towards the end, her comfort level was best when alternating running and walking for 3-4 km, three to four times per week. The client reached her objective of finishing an olympic distance triathlon. The exercise programme also helped to increase lower limb strength and improve physical performance. This case report suggests that it is possible to return to running up to 1 year after total knee arthroplasty. Future research should study bigger samples and monitor implant wear to provide better guidance to patients and physiotherapists.
