Surgery for Osteoarthritis of the Knee
Although total knee replacement is an excellent treatment of end-stage osteoarthritis of the knee in the older (>65 years) population, many patients with less severe disease are significantly impacted by their symptoms and have failed to respond to less invasive treatment alternatives. For this group, there are several less invasive surgical alternatives, including arthroscopic meniscectomy, grafting of symptomatic areas of bone marrow lesions, unloading osteotomy, and unicompartmental knee replacement. Current total knee arthroplasty designs can be expected to survive 20 years or more in the older, less active population. New materials may extend that survivorship.
