Arthroscopic Chondroplasty: Chemical Augmentation for Cartilage Defects

Arthroscopic chondroplasty (sometimes termed “chromeplasty” in older literature) treats symptomatic articular cartilage defects by applying bioactive agents (chondroitin sulfate, hyaluronic acid, PRP, or marrow stimulation) to the lesion bed via arthroscopy.

Goal

Promote fibrocartilage repair, reduce pain, improve function. Not true hyaline regeneration.

Indications

• Outerbridge grade II–III lesions
• Mechanical symptoms (catching, locking)
• Failed conservative management

Limitations

Evidence modest; newer techniques (MACI, osteochondral allograft) offer more durable hyaline-like repair for larger defects.
