What happens to the tendon in cases of chronic tenosynovitis during movement?

In cases of chronic tenosynovitis, the tendon becomes inflamed, leading to various symptoms during movement. One of the key characteristics of this condition is the presence of articular crepitus, which refers to a grating or crackling sound or sensation that occurs when the tendon moves within its sheath. This occurs because the inflamed tendon may not glide smoothly, causing friction and resulting in these audible and tactile sensations.

Additionally, pain is a common symptom associated with chronic tenosynovitis. Patients often experience discomfort when the affected tendon moves, impacting their ability to perform certain movements without pain. This combination of crepitus and pain is indicative of the underlying inflammation and the interaction between the tendon and its surrounding structures during activity, making option C the accurate choice in this scenario.

While significant swelling can occur, particularly in acute cases, it may not be as prominent in chronic conditions. Muscle wasting is not a direct symptom of tenosynovitis itself; it could be a consequence of disuse over time rather than a primary effect of the condition. The absence of symptoms is inaccurate when discussing chronic tenosynovitis, as the condition typically manifests through pain and movement-related issues.
