When knee pain begins to interfere with your daily activities, it’s natural to start exploring surgical options. Two common procedures—knee replacement and knee arthroscopy—address knee issues differently. Understanding the differences between them can help you and your orthopedic surgeon choose the best approach for your needs. At the practice of Steven C. Thomas, MD and Donald W Pennington, DO, our board-certified surgeons specialize in orthopedic procedures in the Las Vegas area.
What Is Knee Replacement?
Knee replacement, also called knee arthroplasty, is a major surgical procedure that involves removing damaged cartilage and bone from the knee joint and replacing them with artificial components. This is typically recommended for severe arthritis or extensive joint damage that hasn’t responded to conservative treatments.
What Is Knee Arthroscopy?
Knee arthroscopy is a minimally invasive procedure in which a small camera (arthroscope) and specialized instruments are inserted through tiny incisions. Surgeons use this technique to diagnose and treat a variety of knee problems, including torn cartilage, loose bodies, and inflamed tissue.
Key Differences Between the Two Procedures
Invasiveness:
-
Knee replacement is an open surgery with larger incisions and significant tissue alteration.
-
Knee arthroscopy uses small incisions and causes minimal disruption to surrounding tissue.
Conditions Treated:
-
Knee replacement: Severe osteoarthritis, extensive cartilage loss, advanced joint deformities.
-
Knee arthroscopy: Meniscus tears, ligament injuries, cartilage damage, early arthritis.
Recovery Time:
-
Knee replacement: 3–6 months for full recovery, with structured physical therapy.
-
Knee arthroscopy: 2–6 weeks for most activities, though rehab may be longer for major repairs.
Durability of Results:
-
Knee replacement: Long-lasting relief, typically 15–20 years.
-
Knee arthroscopy: Relief depends on the underlying condition; may delay but not replace the need for joint replacement in some cases.

Factors influencing your choice include:
