Anatomy and Physiology. Internal derangement of the knee is a mechanical disorder of the knee which interferes with normal joint motion and/or mobility. A fragment of soft tissue or bone that suddenly becomes interposed between the articular surfaces is the classic cause of internal derangement.
Typical injuries treated for the knee are internal derangement, which is a torn medial meniscus; torn anterior cruciate ligament; patellofemoral arthritis; instability and chondromalacia; tendonitis and bursitis about the knee joint with torn ligaments; and tendons and tendonitis in the knee joint.nternal derangement of the knee (IDK) involves either a ligament or medial meniscal tear, which are two of the soft tissue structures that stabilize and cushion the knee joint (the other two are muscles and tendons).
