Osteochondral Defect

This video captures arthroscopy of a patient who complains of knee pain after a fall. Since the fall, he has been experiencing pain and swelling in the knee.

The video shows a detached piece of cartilage from its bed. It is floating off its bed and can be easily peeled off. Also, notice how the surrounding cartilage is easily peeled off from the underlying bone.

This patient subsequently went for a cartilage transplant and has since returned to active sports. (watch video on cartilage transplant)
