This study demonstrated no association between high physical activity level and an increased risk of all-cause revision surgery or revision surgery due to aseptic loosening during the first 12 years following total knee arthroplasty (TKA).  

While these findings are encouraging to those of you with TKAs who continue to stay active there are many factors to consider:

• The TKA implant design, materials and the contact geometry.  For example, higher contact stresses occur in knee flexion so activities like jogging and downhill skiing may cause undue wear and tear
• The more active you are, the more wear and tear
• The type of activity
• The health, conditioning and experience of person with TKA

This is not to discourage staying active!  But as with any artificial joint, you should take care to understand your implant and sport and what modifications are necessary to protect both you and the implant.
