My brother a knee looks like it is protruding. Almost as if the bottom half of his leg is shifted backwards making the knee stick out a lot! His leg is also very hyper extended, but only that one leg! The other is completely fine and nice and straight. This condition was not always this way, he one day just noticed that one of his knees was hyper extended a bit. It is our belief that it has gotten worse over time! Please, any ideas what is wrong?
Hi, thank-you for providing the brief history. A thorough clinical examination is advised along with an x-ray or an MRI. As the knee is in his it needs a thorough clinical examination and an MRI to understand the ligament injuries.Also, there will be shortening of the qua Chat Doctor.  You may need a thorough assessment and a physical therapy to help make this anatomical corrections. Regards Jay In
