Knee replacement surgery or knee arthroplasty is a surgery carried out to replace all or some portion of your knee joint. Your surgeon will replace damaged cartilage and bone with a prosthetic joint.
The duration of knee replacement surgery is determined by the specific type of surgery, the patient’s general health condition, and various intraoperative complications. Usually, it takes around 1 to 2 hours to complete. This period increases when other surgical procedures such as ligament repairs, or complicated revisions are performed. It also includes the preparation and treatment before and after the surgery; therefore, a patient typically spends a few days in a hospital. Current studies show improved recovery times due to technology and procedure innovations.

Surgery to replace all or part of your knee joint is known as a knee replacement. It is a type of procedure called an arthroplasty (joint replacement). During the procedure, an orthopedic surgeon will remove damaged parts of your natural knee joint and replace them with an artificial joint made of metal and plastic. This artificial joint is known as a prosthesis.
The following are the two types of knee replacement surgeries:

Partial and total knee replacement differ in the area of the knee being “reconstructed” and the recovery process.
Partial Knee Replacement (also known as unicompartmental knee arthroplasty or UKA) involves replacing only the affected part of the knee, preserving healthy areas. It is performed for osteoarthritis in one knee compartment, typically the medial or lateral compartment. UKA requires a smaller incision, less bone removal, and generally leads to a quicker recovery.
Total Knee Replacement involves replacing the entire knee joint with an artificial implant. This is typically done in cases of widespread osteoarthritis affecting multiple knee compartments. The procedure removes damaged cartilage and bone in all three knee compartments and replaces them with prosthetic components.
The choice between partial and total knee replacement is multifaceted and depends on such aspects as the degree of knee arthritis, the nature of its localization, age, activity, and other health indicators of the patient. Partial knee replacement can be more beneficial due to faster recovery, and preservation of the natural knee parts. However, it is not indicated for everyone, especially patients with more severe knee arthritis or its wider distribution. Therefore, it is important to consult an orthopedic surgeon.

Knee replacement surgery usually takes about 1 to 2 hours, though the exact time can vary based on the type of surgery, your overall health, and whether any complications arise. If extra procedures, like ligament repairs or more complex revisions, are needed, the surgery may take longer. Keep in mind that the time spent at the hospital also includes pre- and post-surgery care, so most patients stay for a few days. Fortunately, thanks to advancements in technology and surgical techniques, recovery times have improved significantly in recent years.
Undergoing knee replacement surgery is a big decision, and it’s completely normal to have lots of questions. Whether it’s before or after your surgery, don’t hesitate to talk to your surgeon and healthcare provider about any concerns you may have. While recovery from knee replacement can take a few months, most patients find relief from pain and enjoy better joint function afterward. Your surgeon can guide you on when it’s safe to return to your usual activities and what to expect as you heal.

Q: How long after knee replacement can you walk?
A: After knee replacement surgery, most patients are able to walk without the use of a cane or walker six weeks of the time. Everybody's journey to recovery is unique.
Q: How long will the artificial knee joint last?
A: According to research, more than 82 percent of total knee replacements are still functioning well after 25 years. However, wear and tear can adversely affect its performance and lifespan. Younger people are more likely to require a revision at some point during their lifetime, mainly due to a more active lifestyle. Discuss with a doctor about your particular situation.
Q: Can I go home the same day after knee replacement?
A: Same-day surgeries, also known as outpatient surgeries, occur when a patient leaves the hospital on the day of the procedure in a safe manner to recover at home. Of my patients undergoing knee replacement surgery, between one-third and half can return home the same day as their treatments.
