Why is my son having flat feet complain of knee pain?
Patient: what type of doctor would you suggest can look at my son 14 years old with flat feet who has been wearing orthotics for over 5 years and is now complaining of knee and ankle pain and is sad he cannot play football anymore due to the pain in the knees. We are based in Dubai and would ideally like to consult with someone in the UAE or India or any great doctor elsewhere. Help please. thank you my email address is YYYY@YYYY Doctor: Hello,  With the history, it sounds that due to the usage of orthotics within the shoe for flat feet there is the cause of pain in the knee.  This is one of the most common problems people face when they have flat feet. Using orthotics is only when there is walking. When a person is trying for sport the orthotics need to be avoided as it will apply high pressure over the joints of the lower limbs. The pain must have caused due to changing in the biomechanical forces in the joints due to this.   What I will suggest as per my experience of 12 years in sports physiotherapy is that, avoid orthotics while playing sports. Use orthotics only when just walking. try doing exercises like lower limb strengthening and balance board rehabilitation. This should give good outcome scores for the patient.  Hope I have answered your query. Let me know if I can assist you further.  Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist
