Full recovery after knee arthroscopy will depend on what type of problem was treated.
Problems such as a torn meniscus, broken cartilage, Baker's cyst, and problems with the synovium are often easily fixed. Many people stay active after these surgeries.
Recovery from simple procedures is fast in most cases. You may need to use crutches for a while after some types of surgery. Your provider may also prescribe pain medicine.
Recovery will take longer if you have had a more complex procedure. If parts of your knee have been repaired or rebuilt, you may not be able to walk without crutches or a knee brace for several weeks. Full recovery may take several months to a year.
If you also have arthritis in your knee, you will still have arthritis symptoms after surgery to repair other damage to your knee.
