The condition characterized by inflammation of the synovial membrane is synovitis. The synovial membrane is a thin layer of tissue that lines the joints and produces synovial fluid, which lubricates the joint and provides nourishment to the cartilage. When this membrane becomes inflamed, it can lead to symptoms such as joint pain, swelling, and stiffness.

Synovitis can occur due to various factors, including autoimmune disorders, infections, or injury. The inflammation can disrupt the normal function of the joint, leading to discomfort and restricted movement. Understanding this condition is important for personal trainers as it may affect a client's ability to perform certain exercises or participate in physical activities, requiring modifications or a referral to a healthcare professional.

Other choices refer to different conditions affecting various tissues or structures in the body. Bursitis involves inflammation of the bursae, which are small fluid-filled sacs that cushion the bones, tendons, and muscles. Tendinitis, on the other hand, is the inflammation of a tendon, typically due to overuse or strain. A contusion refers to a bruise caused by direct trauma to a muscle or tissue. Each of these conditions has distinct characteristics and implications for treatment and exercise.
