Differential Diagnosis for Knee Joint Sensitivity to Touch

  • Single most likely diagnosis
    • Patellofemoral Pain Syndrome (PFPS): This condition is characterized by pain around or behind the patella, often exacerbated by activities that put stress on the knee, such as climbing stairs, squatting, or jumping. Sensitivity to touch in the knee joint area can be a symptom, making it a plausible diagnosis for knee joint sensitivity.
  • Other Likely diagnoses
    • Ligament Sprains: Injuries to the ligaments surrounding the knee can cause pain and sensitivity, especially if the sprain is acute. The most common ligaments affected are the medial collateral ligament (MCL), lateral collateral ligament (LCL), anterior cruciate ligament (ACL), and posterior cruciate ligament (PCL).
    • Meniscal Tears: Tears in the menisci, which are cartilage structures in the knee joint, can cause pain, locking, and sensitivity in the knee. The symptoms can vary depending on the location and size of the tear.
    • Bursitis: Inflammation of the bursae, fluid-filled sacs that cushion the knee joint, can cause pain and sensitivity, especially if the bursitis is located near the surface, such as prepatellar bursitis.
  • Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
    • Septic Arthritis: An infection within the knee joint, which is a medical emergency. Symptoms can include severe pain, redness, swelling, warmth, and decreased range of motion. Prompt diagnosis and treatment are crucial to prevent joint destruction.
    • Osteonecrosis: Also known as avascular necrosis, this condition involves the death of bone tissue due to a lack of blood supply. It can cause pain and sensitivity in the knee and, if not addressed, can lead to collapse of the bone and severe arthritis.
  • Rare diagnoses
    • Complex Regional Pain Syndrome (CRPS): A condition characterized by chronic pain, inflammation, and hypersensitivity in one of the limbs after an injury or trauma. It's rare but can cause significant disability and requires early intervention.
    • Neuroma: A benign growth of nerve tissue that can develop in the knee, causing pain, sensitivity, and sometimes a palpable mass. It's less common in the knee area compared to other parts of the body but should be considered in the differential diagnosis for unexplained knee pain and sensitivity.
