Which of the following is a characteristic of tissue remodeling around an implant?

• A. Bone remodeling in isolation
• B. Implant encapsulation
• C. Cartilage deposition at interface
• D. Muscle hypertrophy near implant

Answer: (B)

When tissue remodels around an implanted device, the body often forms a fibrous capsule that surrounds and isolates the implant. This encapsulation is a common part of the healing response to inert materials, reflecting the foreign body reaction where fibroblasts lay down collagen to create a protective barrier around the implant. It explains why encapsulation is described as a characteristic remodeling outcome. The other options don’t fit this typical pattern. Bone remodeling in isolation would imply bone changes without a surrounding barrier, which isn’t the general hallmark of the tissue response to an implanted object. Cartilage deposition at the interface isn’t a normal or expected reaction to most implants, and muscle hypertrophy near an implant reflects a different adaptive process rather than the standard remodeling around the implant itself.
