Most of the family physicians more often encounter patients with knee problems. An accurate diagnosis must require detailed information about common pain sequences in knee injuries, knee anatomy and factors of frequently occurring causes of knee problems. However, the specialized skills of a doctor to perform physical examination are a must to attain diagnosis for the patient with a knee problem. The doctors perform a physical exam in order to diagnose the knee problem by carefully inspecting the palpation for tenderness, knee pain, range-of-motion test, evaluation of joint effusion, assessment of ligaments for laxity or injury, and occurrence of the menisci. However, a doctor is more likely to:

  • Examine your knee for pain, swelling, warmth, tenderness and visible bruising
  • To monitor or evaluate the integrity of the muscles and the structures which are present in your knee by pulling or pushing the joint
  • And doctors also observe that how far a patient can move his/her lower leg in various directions

In addition to the physical examination, the doctor also inquires the patient for a detailed history of any past knee problem or injury to get help with obtaining an accurate diagnosis. The history of the patient must include factors related to the pain, joint effusion, timing of pain, the mechanism of injury, and mechanical symptoms such as locking or popping of the patient.
