What is the healing outcome for injuries to the superficial zones of articular cartilage?

• A. Heal immediately
• B. Cannot self-repair
• C. Take several months
• D. Require surgical intervention

Answer: (A)

Injuries to the superficial zones of articular cartilage have a unique healing response due to the structural and biochemical characteristics of this specific region. The superficial zone is the most superficial layer, comprising a dense network of collagen fibers and having a rich supply of chondrocytes. This area is crucial for maintaining the integrity of the articular cartilage and facilitating the function of the joint. While it is important to note that articular cartilage generally has limited healing capacity, superficial injuries can exhibit a relatively more favorable healing response compared to deeper zones. The presence of synovial fluid and the local chondrocytes can promote a degree of repair, leading to a quicker recovery in the superficial layer. The potential for immediate healing stems from the ability of superficial injury sites to respond to load and movement, as well as the relatively less complex nature of the tissue in this region. Although not every superficial injury will resolve immediately, many can show signs of healing sooner due to these factors. Therefore, the healing outcome for injuries to the superficial zones can indeed be viewed as having the potential to heal rapidly, making this answer appropriate. In contrast, deeper injuries often struggle to heal due to inadequate blood supply and a lack of cell proliferation, which necessitates more complex interventions
