Pain above both knees can be caused by several reasons: 1. Bilateral osteoarthritis, when bilateral osteoarthritis of the knee joint can be accompanied by osteophytes of the knee joint, when there can be bone spur formation on the upper edge of the patella of the knee joint, which can cause pain above the knee. Patients with osteoarthritis of the knee can also have secondary synovitis, which can also cause pain in the suprapatellar capsule above the knee. This is diagnosed and treated by early examination of knee x-ray and CT. 2. Synovitis, when synovitis of the knee is secondary to cold, strain or gout, rheumatoid, etc., there can be pain in the suprapatellar capsule above the knee, often accompanied by fluid in the knee cavity and limited joint movement, which is diagnosed and treated by examination of MRI and ultrasound of the knee.
