Overview
Microfracture stimulates cartilage repair by creating small holes in bone.

Indications
Small, focal cartilage defects in active patients.

How it is done
Arthroscopic awl creates microfractures to release healing cells.

Risks and considerations
Repair tissue is fibrocartilage, which may be less durable.

Recovery timeline
Non-weight bearing is common for several weeks; return to sport can take 4 to 6 months.

When to seek care
Swelling or pain beyond expected recovery should be assessed.
