Which of the following best describes the outcome of interarticular adhesions?

• A. Increased joint mobility
• B. Joint hypomobility
• C. Improved flexibility
• D. Enhanced range of motion

Answer: (B)

Joint hypomobility is characterized by a reduction in the normal range of movement in a joint, which is a direct consequence of interarticular adhesions. These adhesions are essentially abnormal bands of fibrous tissue that form between the surfaces of the joint, leading to restrictions in motion. When these adhesions develop, they prevent the smooth gliding of the joint surfaces, resulting in stiffness and reduced mobility.

In contrast to other potential outcomes like increased joint mobility, improved flexibility, or enhanced range of motion, which imply that joints are functioning optimally and moving freely, the presence of interarticular adhesions unequivocally results in a locked or restricted joint state. Therefore, the best description of the outcome is indeed joint hypomobility, as it precisely captures the limiting effect that adhesions have on joint function.
