Answer:
b. Cartilage thinning
Step-by-step explanation:
The joints of our body are lined with hyaline cartilage, a tissue with unique characteristics that can shape and make bones slide in perfect sync over each other. The cartilage tissue acts as a lining of the bony surfaces of the knee, preventing friction between them and also absorbing the impact we generate when we move.
The nonweight bearing or overweight can lead to a damage to this cartilage, which can cause pain, loss of movement, accumulation of fluid content in the knee and, in more severe cases, lead to cartilage thinning.
