The examiner lifts the lower limb of the other side and bends the knee joint as much as possible to make the thigh stick to the abdomen and observe it. Whether the flexion activity occurs in the contralateral knee joint, and if there is flexion, the hip joint has flexion deformity. (2) Bilateral knee and hip flexion test: The patient is in the supine position, and the examiner bends his knee joint as much as possible, pushing his knee as far as possible to the head.

If there are lesions of these two joints, pain can be caused, and further examination can be made according to the pain site to determine which joint the pain is in.
