A young client in his early twenties came to see me with pain on the lateral side of his right knee a few days after playing tennis.
But as often happens, the knee was not telling the whole story.
On assessment I found a flat overpronated foot and significant tightness through the posterior chain. In this kind of pattern, I often suspect that the foot intrinsic muscles are not doing enough of their quiet but essential work.
These small muscles under the foot are rarely discussed, yet they help support the arch, guide balance, improve load sharing, and give the whole lower limb a better mechanical foundation. When they become inhibited, the foot can collapse too easily, the chain above starts compensating, and the knee may end up receiving forces it was never meant to manage alone.
So sometimes lateral knee pain after tennis is not just a knee story.
Sometimes it is a foot to knee to hip story.
This is why I always look at the body as a connected chain rather than a collection of separate complaints. The painful area is not always the place where the trouble began.
