2. Office Jobs
You might think that the kind of work most likely to lead to a knee injury would be something physical that involved spending a lot of time on your feet. In fact, though, the opposite can sometimes be true!
Jobs that involve sitting for long periods of time can actually place the most strain on the joints because they cause uneven development of the muscles. The leg extensors (used to kick the leg forward) may become elongated and weaker, and the hamstrings and glutes can become tighter and shorter. This uneven development can then end up pulling on the knee joint and causing discomfort.
