Joint Warmth
Warmth of the knee joint develops in a number of abnormal and normal settings. Knee joint might become warm as a result of the healing process usually after a surgery like arthroplasty i.e., the replacement of joints. Moreover, a physical trauma or injury such as bleeding into a joint, bruising, or fracture might also lead to warming up the knee joint area. Knee joint warmth might also be a symptom of psoriatic arthritis, rheumatoid arthritis, or an infection. The direct or indirect involvement of knee joint in the bacterial infection leads to significant warming up of the knee. Other knee problems which might be the cause of knee warmth include Osgood-Schlatter’s disease, septic arthritis, cellulitis, dislocated knee, stress fracture, slipped femoral epiphysis, torn meniscus, patellofemoral pain syndrome, rheumatic fever, ACL injury, or repetitive motion trauma.
