Medial compartment arthritis (usually osteoarthiritis) can cause pain on the inner side of the knee. This is usually more of an ache than a sharp catching pain and is present when you walk on the leg. As the arthritis worsens the pain can become continuous and interfere with sleep.
Though the pain usually occurs on the outer side of the knee just above the knee joint, it may also occur over the entire iliotibial band or just below the knee, where the iliotibial band inserts into the shinbone (tibia). The pain usually sets in slowly, often after running for several minutes.
