Recently, I was treating a patient who had knee pain and difficulty doing certain sports activities. Radiological exams did not reveal any lesions in the knee. During the physiotherapy assessment, the knee pain could not be elicited. However, I found a muscle weakness in the hip/gluteal area as well as a significant lack of joint mobility in the foot. Thus, my clinical impression is that the issues in the hip and the foot were contributing to the knee pain, since the entire leg like other regions of the body functions as a whole, like a chain. In the end, without having to directly treat the knee, we succeeded in eliminating the pain and in significantly improving his athletic performance. In conclusion, in certain cases, the factors contributing to pain in a specific part of the body can originate from elsewhere due to the connectivity of various areas.
