There Are Five Main Types of Knee-Replacement Surgeries

February 24, 2022

Countless people suffering from “bad knees” were relieved when, in the early 1970s, surgeons started performing knee replacements. The doctors said that the implants would last for about 10 years. Things have advanced since then, though. Knee replacements now stay the course for an average of two decades! 

At the office of Nutley Orthopaedic Group, our skilled professionals are experts at diagnosing orthopedic issues as well as providing the treatment needed to maintain excellent orthopedic health. Your care and comfort are our top priorities. We will take as much time as you need to address your every concern and explain your options in care. 

An estimated 600,000 knees get replaced in the U.S. each year. That’s why potential patients should be aware that there are five types of knee replacement operations. 

    1. A total knee replacement is the most common kind. The surfaces of the thigh bone and shin bone that connect to the knee are replaced. 
    2. A partial knee replacement is performed only on patients whose knees have sturdy ligaments and normal cartilage. Partials require incisions that are smaller than totals. 
    3. Patellofemoral replacement surgery addresses only the underside of the kneecap and the hollow in which the kneecap sits. This method can be very good for people who have chronic arthritis of the kneecap.


  • Complex (or revision) knee replacement might be needed for those with extremely bad arthritis or who have already had two or three replacement surgeries. 
  • When a knee is worn or has been injured in only a solitary area, that area can be replaced by a living cartilage graft or cells that morph into cartilage.
