Arthroscopic OATS Chondroplasty

This procedure is especially effective in patients with:

• Focal cartilage defects – Localized cartilage loss due to injury or repetitive stress.
• Active lifestyles – Athletes or physically active individuals needing durable joint function.
• Persistent symptoms – Pain, swelling, or instability that does not improve with physiotherapy, injections, or medications.

Prevention goals – Early treatment to protect against progressive arthritis and long-term joint deterioration.

1. Preoperative Evaluation
   The process begins with a thorough clinical assessment, including MRI or X-rays, to determine the size, depth, and location of the cartilage defect.
2. Arthroscopic Access
   Using small keyhole incisions, an arthroscope is inserted to provide a clear view of the joint. Specialized instruments allow precise work without damaging surrounding tissues.
3. Harvesting the Graft
   Healthy cartilage and subchondral bone are collected from a non-weight-bearing region of the patient’s knee.
4. Preparing the Defect Site
   The damaged cartilage is carefully cleaned, and the site is contoured to receive the graft.
5. Graft Placement
   The harvested plug is precisely fitted into the defect, aligning seamlessly with surrounding cartilage to create a stable, smooth surface.
6. Final Check and Closure
   The surgeon confirms graft stability and smooth knee motion before closing the small incisions.

Successful healing after arthroscopic OATS chondroplasty requires a phased rehabilitation plan:

• Initial Protection: Patients use crutches for several weeks to keep weight off the repaired area.
• Controlled Motion: Early physiotherapy emphasizes gentle range-of-motion exercises to maintain flexibility.
• Strengthening Phase: Gradual strengthening of the quadriceps, hamstrings, and hip muscles improves stability.
• Return to Activities: Low-impact activities may resume within 3–4 months, while full sports participation usually takes 6–9 months.

• Restores a natural cartilage surface for smooth, pain-free movement.
• Uses the patient’s own tissue, minimizing rejection risks.
• Achieves long-lasting results in carefully selected patients.
• Helps delay or prevent the development of arthritis.

As with any surgical procedure, risks include infection, graft failure, stiffness, or incomplete pain relief. However, with precise diagnosis, advanced arthroscopic technique, and committed rehabilitation, outcomes are highly successful.

arthroscopic OATS chondroplasty is a minimally invasive, highly effective procedure for patients with localized cartilage damage. By restoring natural cartilage with healthy autografts, it not only relieves pain but also preserves long-term knee function and protects against degenerative changes.
