  • Knee Replacement

    Knee replacement, or knee arthroplasty, is a surgical procedure that involves replacing the damaged or diseased surfaces of the knee joint with artificial implants. The goal of knee replacement surgery is to relieve pain, improve mobility, and restore function in individuals who have severe knee problems.

    The most common reason for knee replacement is osteoarthritis, a degenerative joint disease that causes the breakdown of cartilage in the knee joint. However, knee replacement can also be performed for other knee conditions such as rheumatoid arthritis, an autoimmune disease that affects the joints, and psoriatic arthritis, a type of arthritis associated with the skin condition psoriasis.

    During knee replacement surgery, the damaged parts of the knee joint, including the ends of the femur (thigh bone) and tibia (shin bone), are removed and replaced with artificial components made of metal alloys, high-grade plastics, or ceramic materials. The artificial components mimic the function of a healthy knee joint, allowing for improved joint movement and reduced pain.

    Knee replacement surgery can be a highly effective treatment for individuals with severe knee pain and disability. However, it is typically considered as a last resort when more conservative treatments, such as medication, physical therapy, and lifestyle modifications, have been unsuccessful in providing relief. The decision to undergo knee replacement surgery is typically made in consultation with an orthopedic surgeon who assesses the individual's condition and determines the most appropriate course of treatment.

  • What to Expect From Knee Replacement Surgery Outcomes

    It is true that knee replacement surgery can be highly beneficial for individuals with arthritis of the knee, providing relief from pain and improving mobility. The success rates of knee replacement surgeries are generally high, with good or excellent outcomes reported in 80 to 90 percent of cases. However, as with any surgical procedure, there are potential risks and the possibility of varying outcomes.

    While the majority of patients are satisfied with the results of knee replacement surgery, it is important to acknowledge that there is a small percentage of individuals who may not experience the desired level of satisfaction. As you mentioned, approximately 10 percent of patients may not be happy with the outcome of the surgery. The reasons for dissatisfaction can vary and may include factors such as ongoing pain, limited range of motion, complications, or unmet expectations.

    It is also worth noting that a small percentage of patients may continue to experience some level of pain even after a knee replacement. Studies have reported that around 10 to 20 percent of patients may still have persistent pain following surgery. This pain can be caused by various factors, including inflammation, nerve damage, or the presence of other underlying conditions.

    It is crucial for patients considering knee replacement surgery to have realistic expectations and be aware of the potential risks and outcomes. Consulting with an orthopedic surgeon and discussing individual circumstances and concerns can help in understanding the specific risks and benefits associated with the procedure.



    Thank you for providing information about the recovery process and expectations after a knee replacement surgery. It's important for patients to have a realistic understanding of what to expect during their recovery. Here's a summary of the points you mentioned:

    1. Immediate Pain Relief: While pain relief is provided in the hospital through local anesthetic infiltrations, blocks, and medications, it's important to note that the surgery itself is typically followed by fairly intense pain.

    2. Prolonged Pain: After the surgery, patients may experience relatively minor pain, such as discomfort at the end of the day or before bedtime. However, this can be easily controlled with over-the-counter painkillers like Tylenol or Advil. This type of pain may persist for about six to nine months after surgery.

    3. Maximal Benefit Timeline: The full benefits of a knee replacement are usually not realized until about nine to eighteen months post-surgery. So, patients should not expect complete relief or extreme comfort within the first few weeks.

    4. Post-Surgery Mobility: Patients often use a walker or crutches for a short period, typically until they return home from the hospital (around two to three days). After that, they can transition to using a cane. By three to six weeks, many patients no longer require a cane and can resume activities like golfing, driving (if not on painkillers), swimming, and vigorous walking.

    5. Swelling and Bruising: Swelling is expected after surgery, particularly when patients become more active at home. The knee may remain swollen and warm to the touch for up to a year or two, which is normal. Additionally, bruising on the leg, potentially from the hip to the ankle, is common for a few days to a couple of weeks after surgery.

    6. Numbness: The outer part of the knee may be numb after surgery. This is a normal occurrence and not a cause for concern. Although it is not painful or bothersome, patients may have questions about it.

    It's essential for patients to discuss their specific concerns and recovery progress with their healthcare provider, as individual experiences may vary.

    If you think you have any more questions talk to your local family physician, physiotherapists  or if you’d like to know more about a knee replacement, consult with your physician.
